CHAPTER 6

Planning science lessons

Those who know, do; those who understand, teach ~ Aristotle (384-322BC)

HOW CAN I CONSTRUCT A SCIENCE LESSON PLAN? A science lesson plan presents your specific teaching and learning ideas. Lesson plan structures and content vary according to the type of lesson. There are key components that need to be incorporated in a full science lesson plan. As a beginning teacher, you will need to understand and use these components to consolidate your pedagogical thinking. These components include the intended lesson outcome or achievement standard, lesson duration, key scientific concept, health and safety requirements, the science activity, teaching strategies (including classroom management), resources, assessment, and evaluation. Each of these will be discussed in more detail here.

Intended lesson outcomes (achievement standards) Although you will consider your students’ needs and interests, every lesson must have an intended outcome or achievement standard. There can be little justification for teaching a lesson if it does not have an achievement standard (e.g., outcome, framework, or essential learning, which were classified as aims and/or objectives in the 20th Century). The standard is derived from the presiding science curriculum. Using the curriculum standards justifies your teaching within an education system. Indeed, you have the support and backing of your education department when using the curriculum in the ways advocated. I’ve shown this as “intended lesson outcome” as you may or may not produce evidence that all students attained this outcome or standard within your lesson. Undoubtedly, you will find the need to include supplementary science activities to assist those students who have not achieved the standard. An effective teacher will also provide for students who complete tasks early with extension activities related to the standard. As your teaching practices develop, you will be able to plan science lessons that cater effectively for individuals, including those requiring more assistance and gifted and talented students. As standards (outcomes) and assessments are inextricably linked, it is advisable to select one standard per lesson (unless you are combining it with another key learning area). If you have a class of thirty students then you will be assessing these students on one standard, therefore: 30 students x 1 standard = 30 assessments. I have seen lesson plans that incorporate three or four outcomes (standards). Imagine trying to assess 30 students x 4 standards (120 standards) in a 40-minute lesson! I hope you

will become a “super” teacher but I am yet to see any teacher successfully assess 120 standards in a 40-minute lesson. You need to be very selective with your intended outcome/standard. There may well be four standards that suit a particular lesson, nevertheless, your decision to select the most appropriate standard for a lesson will be based on this question: What standard do I want to assess in this lesson? When selecting an intended outcome (standard), you need to consider the range of student abilities with purposefully selected science activities. It may also be appropriate to assess only half the class on one standard for a particular lesson and then, focused on the same standard, the other half of the class in another lesson (which will be discussed later).

Lesson duration Teachers are watchers of the clock. The school day has a broad schedule of times (start, recess, lunch, end) and further schedules of subject specificity (e.g., sport, art, drama, music). Hence, teachers plan lessons within designated timeframes. The broad school schedule can determine the length of lessons. For example, the duration between recess and lunch in a primary school may not be long enough to conduct certain lessons, while the morning periods may be reserved for particular subjects (e.g., English). You have two main questions to ask when planning the timing of your science lesson, that is: (1) When is the most effective time to teach this science lesson? (2) What will be the duration of this science lesson? There is considerable evidence that students are more mentally active during the morning. Indeed, most primary schools conduct sport, music and art during the afternoon, as students’ conceptual learning does not need to be as intense in these subject areas. Science can involve considerable intellectual interaction and teachers have to make pedagogical decisions to capitalise on the students’ prime learning time. Most schools conduct English classes in the morning and mathematics lessons tend to follow the English prime time. As the intensity of science lessons can vary, an astute teacher will plan science according to the intellectual demands of the lesson. For example, designing a mousetrap car or a balloon rocket may be thought as a “playful scientific endeavour” with group interaction. Engaging and exploring in these activities may be suitably timetabled in the afternoon. Students can explain the science concepts around these activities through diagrams, illustrations, and verbal discussions. Yet, a science lesson that involves more intense conceptual understandings (e.g., velocity) may need to be conducted earlier in the day to take advantage of students’ intellectual capacities. When considering English as a key subject, science can contribute significantly to English-language development. Hence, learning about the structure of a scientific report may be more suited to a morning session, where students focus on language and writing development. These are generally a teacher’s pedagogical choices, which need to be based around the school’s timetable and the students’ needs. Certainly, teachers experiment in timetabling, and this should be one of your decisions when planning to teach science lessons. This will help you to determine the most beneficial scenarios for your class.

Key scientific concepts There is a body of scientific knowledge that’s growing and developing. When you teach a science lesson in the primary school it is generally based on predetermined scientific knowledge. For instance, I was teaching about the human circulatory system to a Year 6 class. I drew upon the scientific body of knowledge available about the human heart as background knowledge for the lesson. Terminology such as aorta, ventricles, veins, and arteries were used to get across scientific concepts. Although I taught students about the four chambers (left and right atria, left and right ventricles) and the four types of values that regulate the blood flow through the heart, the key science concept I wanted to students to understand was: The heart is a pump. http://www.texasheartinstitute.org/hic/anatomy/anatomy2.cfm Just as the heart is a pump for the body, key scientific concepts are at the heart of a well-designed science lesson plan. After deciding on the intended standard, ask yourself this question: What key scientific concept(s) do I want my students to understand at the end of the lesson? Selecting a key concept from the scientific body of knowledge gives further purpose to your lesson and students’ articulation of this concept (e.g., through discussions, labelled diagrams) can act as an indicator on whether your students are achieving the intended standard. Students may extend beyond this key scientific concept but at least you have a benchmark as an standard indicator. Here is another example of key scientific concepts around electricity for an upper primary class. Key scientific concepts: Low voltage direct current (DC) electricity is used to power many portable electrical devices. The most common source of DC electricity is the battery. Batteries have positive and negative polarities. Batteries contain cells with each cell generally producing 1.5 volts. Simple electrical circuits can be made using battery power. You will need to have background information around these key scientific concepts to ensure you are going to teach the topic with accuracy and confidence. Although lesson introductions can occur in many different ways, you may want to discuss this information with the students during a lesson introduction with relevant questioning, to illustrate:

Key Concept Information: a) Working with low voltage electricity means there is no need to be concerned that you may be harmed. This is different to the high voltage electricity that is very dangerous and may be fatal, found in building power points, lights and other locations. D.C. electricity is normally obtained via batteries although occasionally it comes directly from a transformer which is plugged into a power point. Can you name some examples of devices that use DC electricity in the form of batteries? (remote controls, toys, mobile phones, torches, cars, trucks, boats).

Page 4: Chapter 6 Planning Science Lessons

b) A standard cell in a battery produces 1.5 volts. Typical AAA, AA, C, D type batteries contain a single cell which means they all provide 1.5 volts. Although they all put out 1.5 volts, the bigger batteries last longer whilst the smaller batteries take up less room. This means the designers of remote controls and other battery powered equipment have to consider how much power their device is going to use and how small the batteries can be to save space. Some batteries produce more than 1.5 volts (1.5V), which is achieved by adding cells in the battery. Some common batteries provide 3V, 6V, 9V and 12V. How many cells would each of these batteries contain? c) In many situations it is necessary to connect several batteries together in a special way to provide the voltage required for a particular application. When connecting two or more batteries together to increase the voltage, the positive terminal of one battery must be connected to the negative terminal of the next battery. Now for a torch light bulb to glow, electricity must be able to flow along an unbroken path, called a circuit, from the negative terminal of the battery to the positive terminal of the battery. Electricity will flow through materials called conductors that include most metals. However, insulators are materials that electricity cannot travel through, such as wood, plastic, and rubber. What do you think may be other good conductors or insulators?

You may have a student activity sheet that focuses on the key concepts around simple DC electrical circuits. Some of the questions on this activity sheet may include: Q1. What is the most common source of DC electricity for portable devices? Q2. Name six devices that use DC electricity. Q3. What is the voltage of a single cell in a battery? Q4. A typical car battery produces twelve volts. How many cells does it have? Q5. What is the name of the material that electricity can travel through and what are some examples? Q6. What does an insulator do and what are some examples of insulators? Q7. When batteries are joined together to produce a higher voltage, how must they be connected? Q8. What is the name of the path that electricity travels along? Q9. What do you think a switch does in a circuit? Q10. Many trucks use 24V for their electrical systems yet they use 12V batteries. Draw a simple circuit diagram showing the battery or batteries including polarities (negative / positive), a switch (key ignition) and the engine.

Now let’s see how this key concept information may play out within the structure of a lesson (i.e., introduction, body, and conclusion).

Example 6.1: Lesson plan structure with key concepts for an upper primary class Introduction: As we will be working with low voltage electricity, there is no need to be concerned that you may be harmed. This is different to high voltage electricity that is very dangerous and can be fatal, found in building power points, lights and other locations.

• D.C. electricity is normally obtained via batteries although occasionally it comes directly from a transformer which is plugged into a power point. Can you name some examples of devices that use D.C. electricity in the form of batteries? (Remote controls, toys, mobile phones, torches, radios up to larger equipment such as cars, trucks, boats, industrial)

• A standard cell in a battery produces 1.5 volts. Typical AAA, AA, C, D type batteries contain a single cell which means they all provide 1.5 volts. Although they all put out 1.5 volts, the bigger batteries last longer whilst the smaller batteries take up less room. This means the designers of remote controls and other battery powered equipment have to consider how much power their device is going to use and how small the batteries can be to save space. (Show Internet PowerPoint on different batteries, have real batteries in class)

Some batteries produce more than 1.5 volts and this is achieved by having additional cells within the battery. Some common batteries provide 3V, 6V, 9V and 12V. How many cells would each of these batteries contain?

• In many situations it is necessary to connect several batteries together to provide the required voltage. When connecting two or more batteries together to increase the voltage, the positive terminal of one battery must be connected to the negative terminal of the next battery.

• For a light bulb to glow, electricity must be able to flow along an unbroken path, called a circuit, from the negative terminal of the battery to the positive terminal of the battery. Electricity will flow through materials called conductors that include most metals. Insulators are materials that electricity cannot travel through, such as wood, plastic, rubber.

Explanation of task: We are going to form 5 groups to undertake an activity demonstrating a simple electrical circuit. Each group will have a light bulb which needs 6V to power it correctly. The ‘D’ type batteries I will supply are 1.5V. How can we obtain the necessary voltage using the supplied batteries? (Connect 4 batteries in series). How must the batteries be connected together? Body of lesson: Ensure the batteries are inserted into the holder so the positive terminal of one battery is connected to the negative terminal of the next battery. Leave the skill-test wand about half way along the test circuit and you should see the lamp glowing. Starting at the negative terminal of the battery holder, can you trace the circuit the electricity is flowing through? When the wand is resting against the skill-test frame the lamp glows as the entire circuit consists of conductors. When the wand is lifted slightly so it doesn’t have direct contact with the skill-test frame, the lamp goes out. Why? (Air between the wand and frame becomes an insulator). Taking turns, each student attempts to move wand from one end of skill-test frame to the other as fast as they can without making contact with the frame. Each time the student makes contact with the frame, the light comes on and the student has to stop and answer a question card before proceeding with the skill test. Another student times how long the skill test takes, including answering the question cards. Student with shortest time is winner. Conclusion: Consolidate key concepts around DC electricity. Devices require different voltages to power them. For the lamp to glow it was necessary to have a circuit. Electricity travels through conductors, not through insulators. Voltage may be increased by joining batteries together in series with positive terminal of one battery connected to the negative terminal of the next battery.

Selecting a science activity Selecting a science activity or group of activities should be related directly to the achievement standard and key scientific concept(s). It will also provide the basis for assessment. You may find numerous activities that could suit the standard and associated key scientific concept. So, how do you decide on the most appropriate activity? You will need to consider the timeframe, health and safety issues, resources, and suitability of the activity. Students’ abilities, needs and interests must also enter this equation. Note I didn’t include your own content knowledge, as it is assumed you will learn or revise the concepts prior to teaching them. After considering the science syllabus and support documents, commercial texts, the Internet, and other sources, you may now have many appropriate science lessons that could link to the standard (and assessment criteria). With such a choice, and assuming all these activities address the criteria, select the lesson you think would be highly engaging for the students. Science should be fun and hands on wherever possible! Keep the other lessons as back-ups or extensions or as a resource you may need if the students require further conceptual understandings or you can use them as workstation activities. That is, students move from one activity to the next (see Examples 6.2a and 6.2b). Example 6.2a: A selection of activities for rotational hands-on learning

Workstation 1 Objective: Students learn about a hurricane/cyclone and how and where they are formed. Materials: Computer with Internet access Instructions: Follow the prompts on this website and investigate the links - http://www.field-trips.org/trips.htm

Workstation 3 Objective: Students will understand that a powerful sound wave through the air is the cause of thunder. Materials: A sheet of paper (30 cm x 40cm) Instructions: Need to follow instructions in the in 101 Great Science Experiments: A step-by-step guide by N. Ardley.

Workstation 2 Objective: Students will understand that static electricity is the cause of lightning. Materials: A metal tray with handle, polythene bin liner and a metal spoon. Instructions: Lay the bin liner out on a flat surface. Have metal spoon close and ready to use. Turn the light out to make the room dark (or use storeroom). Rub the tray across bin liner for about 30 secs. Don’t touch tray, only the handle. Lift tray up and slowly bring spoon up to it (about 1 cm). Reference: Weather: Science Projects by C. Oxlade

Workstation 4 Objective: Students observe and articulate the twirling motion created to form a tornado Materials: Empty jar, clear liquid soap, vinegar, water, food colouring. Instructions: Fill jar 3/4’s with water. Put a teaspoon of liquid soap into jar and add a teaspoon of vinegar. Tighten lid and shake jar to mix ingredients. Swirl jar in circular motion. Stop and look into the jar. Add food colouring for better effect. See http://www.weatherwizkids.com/tornado2.htm

Workstation 5 Objective: Students observe cold air colliding with warm air, the water condenses and forms a fog. Materials: Beaker, hot water, strainer, ice cubes. Instructions: Fill up the beaker completely with hot water (safety observed). Leave for 1 minute. Pour out almost all the water. Leave one quarter of water in jar. Put strainer over the top of the jar. Place several ice cubes in the strainer. Watch what happens! Be patient! See http://www.weatherwizkids.com/fog.htm

Example 6.2b: A selection of activities for rotational hands-on learning Activity 1 Make rain – Students observe that a cloud forms from water vapour. The vapour condenses and becomes heavy. Materials: Large Pyrex jar, hot water, a cover for the jar, an empty tin can filled with ice cubes Instructions: Pour hot water into jar. Cover the jar with the lid. Place empty tin can filled with ice on top of jar lid.

Activity 2 Make a rainbow – Students observe how the light bends when it enters the water and leaves the water. Materials: Bright light, clear drinking glass, piece of white paper. Instructions: Partially fill the glass with water. Place a glass of water near light beam. Place the white paper under the light beam.

Activity 3 Make lightning – Students will observe that static electricity is lightning. The flash they will see jump is just like lightning Materials: Inflated balloons. Wool clothing - like a wool sweater - or a piece of real fur A metal surface like a filing cabinet or a metal doorknob (group 1 – Metal bar, fork. Group 2 – Dumbbell and pot). Instructions: Inflate balloons. Darken the room as much as possible. Rub the balloon(s) rapidly against a wool sweater or a piece or real fur about ten times or more. Move the balloon close to something metal.

Activity 6.1: Justifying your activity choices Let’s assume you have found seven or so activities for your Year 4 class around the topic “Living things need each other and the environment”. You have considered the various sub-topics and activities. You have already determined that the activities align with the Year 4 curriculum standard (e.g., see Year 4 Australian Curriculum: Science). However, you can only choose three activities that will fit with the rest of your program. Discuss the following questions in relation to the activities suggested:

1. What three activities would you choose? 2. Why did you select these activities? 3. What else would you need to know to make a better choice?

Health and safety requirements There is no doubt that your students’ wellbeing must be your first priority in a school. I can’t emphasise enough that teaching can only occur after you have considered your students’ health and safety. Every science lesson must take into account health and safety requirements. As each lesson is different, you will need to think about the specific health and safety requirements applicable to that particular lesson. Indeed, you will need to be a forward thinker on a student’s health and safety

Page 9: Chapter 6 Planning Science Lessons

Hudson’s guide for teaching primary science

94

regardless of the subject area. For example, while on playground duty I would identify potential dangers and quickly address these with the students concerned. Use this type of predictive behaviour for conducting your science lessons. You will then need to manage potential health and safety hazards. Here’s an outdoors science lesson experience…

When I had conducted bushwalking activities for students to investigate flora and fauna, I would ensure all students had food and drink, appropriate clothing including hats and covered footwear, and I would outline the procedures for the bushwalk (e.g., stay as a group, be with a partner, do not touch any creature, be wary of potential dangers themselves). I would carry in my backpack a mobile phone, torch, thermal sheet, and a basic first aid kit, which I knew how to use through a St John’s Ambulance First Aid course (or you could have a parent who knows how to use it and has attended such a course). It’s important to know the site before taking students for an outdoor science activity. In this case, I explored the bushwalking area with my colleague (and friend) the weekend prior to the lesson. This helped me to identify potential hazards through first-hand experience. Finally, as a back-up plan, I discussed the area with a Parks and Wildlife ranger and notified him of our field trip details.

Always remember your number one priority:

No child should be hurt or placed in danger during the process of learning. There are potential hazards outside the classroom, there are also potential hazards inside the classroom, which must be identified. In its simplest form, you need to think about the basic steps of your science activity where you recognise potential hazards and state how you will manage these potential hazards. This doesn’t need to be lengthy but it does need to show you have considered the students’ health and safety in your planning. This consideration is part of your duty of care and legal obligations. You will find many primary science lessons have few hazards, nevertheless, even seemingly innocuous aspects such as handling scissors, water spillage, or using magnifying glasses have potential danger. Other lessons may require protective gear such as goggles, gloves, or dust coats, and all science lessons should have students with covered footwear (unless there is a special case to be bare footed). I taught at one country school where many kids came to school without shoes! This didn’t appear to present a problem as these little feet had toughened up walking on dirt roads, through bush tracks, or chasing cows across paddocks. Nevertheless, teaching science can involve using equipment and it doesn’t take much to drop a piece of equipment, which tends to land at or on the feet. A pair of scissors can do damage. So I had students bring their shoes in their bags if they were not wearing them to school. Science lessons meant students had to put on their shoes first. Health and safety was party of my legal responsibility. Your lesson plan should include the identification and management of potential risks associated with the lesson. I always articulated these potential risks to the students after the lesson introduction which was just before they commenced the hands-on activity. I would monitor students’ health and safety during the lesson and act quickly if a student was not adhering to my instructions. You may find

Page 10: Chapter 6 Planning Science Lessons

95

students who disregard or forget about the health and safety instructions at times. Repeat offenders are suitably and respectfully managed, as I never beat around the bush when it came to ensuring the wellbeing of each and every student. Try Activity 6.1 to see how you would manage the health and safety aspects of a science lesson.

Activity 6.2: Health and safety management Write the title of a science lesson: ________________________________ Now under the following three subheadings record in point form the basic procedures of students’ involvement in the science activity, potential and identifiable hazards (use predictive behaviour), and how you will manage these hazards. Basic Procedures Identifiable Hazards Management of Hazards

ADDITIONAL NOTES:

Teaching strategies After selecting an appropriate science activity with consideration of your students’ health and safety, you can enjoy designing the structure and form of your lesson. Never underestimate the power of an effective teaching strategy. If you select a teaching strategy purposefully, you will minimise classroom management problems, maximise student engagement, and capitalise on the teaching and learning environment. Each teaching strategy creates a new dimension for structuring your science lesson and provides considerable variety for students.

A person may have outstanding content knowledge but may not know how to impart this knowledge, which can make it difficult for a learner to understand the concepts. As a teacher, the term “pedagogical knowledge” highlights the importance of your role to know how to teach, and teaching strategies provide a way to engage students in learning about a chosen topic. Teaching strategies are so crucial to an effective science lesson that a whole chapter has been dedicated to this topic. Apart from the suggested literature in Reading 6.1, teaching strategies will be discussed in a later chapter.

Resources You need to select an activity that has suitable and manageable resources. These resources can include humans, renewable and non-renewable resources, environments, and the knowledge economy. Human resources can involve those with expertise on a particular topic. Renewable resources can include science equipment and other technologies that can be re-used. The word technology in its broadest sense means anything that has been constructed from raw materials. Hence, some technologies are renewable (e.g., whiteboard, desk, microscope) yet others may be non-renewable (e.g., most writing equipment such as whiteboard markers, pens). Environments are invaluable resources, as they present unique situations for students to learn about science. A classroom environment can be created to construct a “real world” experience. For example, study rocks and minerals would entail setting up the classroom with a good selection of rocks and minerals (and the use of other equipment e.g., magnifying glasses) for hands-on investigations. Environments beyond the classroom such as the school grounds, local community and other more distant locations can open opportunities for students’ explorations. Wetlands, farmlands, factories, rock pools, sand dunes and so forth provide first-hand contexts for investigations. These experiences are appreciated greatly by students if they are well organised and focused on their learning.

Resources incorporate library books, journals and magazines, computer programs and the Internet as part of the knowledge economy. It is ideal to have access to as many resources as possible; however a school’s location and its situation (e.g., public, private, socio-economic) may impose limitations for accessing resources, such as broadband Internet connections. Without doubt, the Internet has the widest range of resources for schools, which is particularly useful for explaining key science concepts and interactivity with science at appropriate levels. For instance, Brainpop (www.brainpop.com) presents a broad selection of science topics with pictorial representations and explanations of the key science concepts. There are competing Internet programs that can be downloaded for scientific exploration (e.g., www.stellarium.org and http://www.nova-astro.com/ecupro.html

show different ways to investigate astronomy). These resources can build students’ understandings though preference should be given to first-hand experiences wherever possible.

There are two key factors for resource access, namely, budget and constructive alternatives. A large budget may allow students access to the latest science equipment and cut costs for involvement in field trips. Those with limited budgets (and that is generally most schools) will need to consider constructive alternatives. For example, I wanted to take my upper primary students on a rainforest excursion that was different to the coastal rainforest in my district. I had planned a three-day excursion but the cost of a bus and bus driver made the excursion too expensive for some students. I realised early in my career that having a bus licence to seat 25 students would come in handy. So, taking my class on rainforest excursions and camping for three days at places such as Mount Warning area became viable propositions, which agreed with parents and received considerable parental support. Other constructive alternatives may include assistance from the community. For instance, I wanted an overnight camp on the school grounds to view the evening sky. Purchasing a telescope was out of reach for my school but, fortunately, a community member offered a telescope and his services at the school for the evening. I learnt with the students! This shouldn’t really come as a surprise, as I learn every time I investigate science with my students; although my learning is enhanced greatly when experts in specific fields are involved in educating my students.

Assessment Don’t get assessment and evaluation confused. Here’s a definition of assessment for education purposes and the next section will discuss evaluation.

Hudson’s guide for teaching primary science

Assessment is the process of collecting, analysing, and recording information about a student’s progress that indicates the level of achieving predetermined syllabus standards.

This definition is analysed in more detail in Chapter 10. In broad terms though, think of assessment as information about a student’s learning. Assessment, standards, key concepts, and the science activity are very closely related. Both the process and the product of students’ involvement in the science activity can be assessed. Your lesson plan needs to locate process and product inputs and outputs that can adequately determine a student’s learning achievements. Pinpointing a student’s achievements aligned with a standard will require evidence or indicators for verifying this attainment.

Evaluation Fundamentally, assessment is about data collection while evaluation is about making a determination on the quality of the teaching and learning.

Evaluation is an ongoing reflective judgement on the quality of teaching practices and the learning environment.

Growth as a professional occurs through first-hand experiences followed by critical self reflection. After implementing a lesson, you need to reflect on your teaching and the learning environment. This reflection is then translated into an evaluation of the teaching and learning. You can evaluate any assessment you have conducted, particularly in terms of achieving the standard with evidence of students’ learning of the key science concepts. Evaluation can enter all aspects of students’ involvement in a science activity. A later chapter presents evaluation in far more detail. For example, even though a teacher considers health and safety before implementing a lesson, the teacher would always evaluate this aspect during the lesson and after the lesson. There may be a need to enforce safety procedures that were not considered in the planning. Experienced teachers comment on aspects of a science lesson’s health and safety such as: “I’d change the location of this activity next time because it was too long in the sun” or “I quickly realised that some kids were not wearing gloves, so I stopped the activity and made sure they put them on”. These judgements help to advance the teacher’s practices for current and future work. Refer to Figure 6.1 to see the relationship between evaluation and other components of a lesson. There are a few aspects to note. First, you can assess students’ learning of the standards, key concepts, and their involvement in the activities. Second, you can evaluate students’ achievement of standards and key concepts in terms of the teaching and learning environment. Third, you can evaluate all the components of an activity including the health and safety, duration of the lesson, resources, and teaching strategies, which can also involve classroom management. Finally, you can evaluate the processes and products of an assessment linked to students’ “zone of proximal development” (ZPD). Figure 6.1 shows the connections for planning a science lesson. You can also discuss Activity 6.2 towards setting up your science lesson plan.

Activity 6.3: Setting up your classroom lesson plan You have just arrived at your new school and shown your new classroom. What steps would you take for teaching science? Also you should be noticing the connections between the science overviews and lesson planning.

Science topics from the syllabus and school’s policy Lesson timeframe and duration Intended outcome or achievement standard Health and safety issues and management of potential hazards Resources (e.g., support documents, texts, Internet sites, materials and

equipment) Prior knowledge (students’ abilities, needs and interests) Content knowledge – key scientific concepts Teaching strategies Classroom management Engaging hands-on science activity or activities Assessment considerations Evaluation questions

WHAT TYPE OF SCIENCE ACTIVITIES CAN I DO? Science learning can be designed in many forms. The type of activities is limited by the age and stage of the group, curriculum standards, health and safety requirements, resources, and lesson appropriateness. Below are sample activities that I have facilitated in classrooms and with my preservice teachers. These activities target primary students in years 5 and 6, although it is easy to

Page 15: Chapter 6 Planning Science Lessons

Hudson’s guide for teaching primary science

100

simplify and complicate the activities for lower or upper grades, respectively. These rotational activities are conducted with 2-4 students in each group. For preservice teachers, it takes about 10-15 minutes to complete an activity while discussing pedagogical possibilities before rotating to the next activity. In a primary classroom each activity can be converted into a full lesson. A “Science and Society” component that investigates historical and current developments of concepts can be included within many of these activities. For example, reading star maps may also entail investigating the development of astronomy (e.g., archaeoastronomy – Stonehenge and early astronomers such as Plato, Copernicus, Galileo) and current astronomical developments (see NASA; Neil Armstrong walking on the moon, Hubble, Voyagers I & II, galaxies). Concise steps are provided to activities for investigation and critical analysis. You will note that a teaching approach also has been assigned to each activity. I would recommend having at least one computer connected to the Internet (ideally one computer per group allows for easier access to informative websites). If not, print out some details from a website for the groups. Activity 6.4 refers to the outline of science activities in Example 6.4.

Activity 6.4: Advancing your lesson plan Refer to activities in Example 6.4 and discuss these points: 1. What teaching strategies would you use for some lessons? 2. How would you change/advance one of these activities? 3. Are there other class management strategies you would use for teaching a particular activity? 4. How would you translate one of these activities into a science lesson plan?

Example 6.4 outlines activities that are connected to the Australian Curriculum: Science (ACARA, 2011). You will note there is an achievement standard code associated with each activity. This code can be tracked back to the Australian Curriculum: Science document. Also you will note that there are different sciences (i.e., biological, earth and space, chemical, and physical). Example 6.4 presents different activities across these sciences for all primary grades, including the foundational level. The way you devise and conduct the lesson is reliant upon your own pedagogical creativity.

Example 6.5 outlines a basic lesson plan structure around a Physical Sciences topic “Building bridges”. There’s introduction with a stimulus and body of the lesson where students are involved in hands-on experiences. You will note that the key concepts are a thread throughout the lesson, and lead to a purposeful conclusion around these concepts. Example 6.5: Basic lesson structure PHYSICAL SCIENCES – Year 4

Building Bridges (50 minutes) Achievement standard: Forces can be exerted on one object by another Key concepts: Materials used for making bridges need to be tested for compression and tension.

Safety: Explain safe use of scissors and sun protection when held outside. Resources include: straws, paddle pop sticks, sticky tape. Sticky tape usage must be limited.

Teaching and learning activities Introduction: (≈10mins) Teachers provide a stimulus on the topic about building bridges with a selection of introductory, hands-on activities (e.g., see www.TeachEngineering.org). Teachers question students on their prior knowledge and understanding of these concepts and then ensure clarity of new terms (e.g., bridges – compression, tension). Body: (30mins) Students are provided with cooperative learning roles and interact with hands-on activities to construct a truss bridge (www.TeachEngineering.org). Teachers monitor students’ thinking and progress and use higher-order thinking questioning throughout the hands-on task. Students continue making a truss bridge and write notes on their discussion, particularly when they test their bridge design for compression and tension. Conclusion: (5-10mins) The conclusion consolidates the key concepts about compression and tension. Students are asked to demonstrate these concepts (e.g., through discussion, diagram, practical demonstration, written statements). Assessment: Teachers listen to students’ articulation of key concepts (throughout the lesson and also in the conclusion). Work supplied by the students (i.e., written notes and bridge construction) will be assessed in terms of quality and understanding of key concepts. Evaluation: Students reflect upon their learning experiences and the learning environment. Teacher also reflects on the teaching practices for enhancing strategies in subsequent lessons. Extension: Students illustrate and label their products and write scientific statements about their bridges.

Activity 6.5: Reviewing ideas for setting up science lesson plans Example 6.6 presents considerations for structuring a lesson.

1. Review and discuss Example 6.6 and critically analyse these considerations. What else would you include/exclude?

2. Look at the questions associated with Example 6.6. What questions would you ask?

3. What do you think the lessons are about? What could be the hands-on activities?

INTRODUCTION Gaining learner interest, establishing conceptual basis. 5-10 mins EXPERIMENT Student inquiry and investigation 20-25 mins CONCLUSION Bringing together ideas, reinforcing key concepts and intended outcomes 5-10 mins

• Read the Three Little Pigs • Ask questions about the materials used to build each

house. What did the pigs use to build their houses? Why do you think the first two houses blew away? Which house was most stable? Why?

• Ask students to list the properties of each material (straw, sticks, bricks) and suggest why they were suitable for building or not. What are the properties of the materials that did not work? What about the materials that did?

• List in a table on the overhead transparency (OHT) three materials. Consider hard/soft, heavy/light.

• Introduce experiment by posing questions: What other materials might be good for building? How can we find out?

• Hand out playing cards and split class into five groups. Ask students to move to their groups.

• Explain experiment… what they will be doing generally. MODEL how to use the hair dryer.

• Outline group expectations: co-operative work, everyone has a go, discuss results, record on sheets. If early finished then ask students to work out how far it moved.

• During experiment, circulate through class monitoring behaviour and eliciting students’ understandings by asking questions: What have you noticed about the materials in each category? Why do you think you need to make sure the hair dryer is at the same place each time?

• Can you tell me something about the materials that you think may be good or bad for building? Call class back to whole group scenario

• Ask each group to identify which materials were in each category, record results on a chart, in the case of disagreements – discuss why, ask students to give a reason for their choice.

• Create a table of properties of good building materials, use questions to elicit responses: What do you notice about all the materials that are good? What do they have in common? Would you say they are hard/soft, heavy/light? Do they move/bend? Did they pass the blow test?

• Use questions to guide discussion about why some materials are suitable for building and others are not: Why do you think this material was/was not suitable? What do you think are the best materials for building/why? If you were going to build a house what would you use? Why?

• Sit on floor and listen to story

• Reflect on story, answer questions.

• Split into groups • Observe

teacher’s use of hair dryer

• Do experiment in

groups • Record results • Discuss reasons

why the materials are suitable or not for building

• Discuss results

Assessment: Observe participation of group discussions. Observe appropriate behaviours. Ask questions to elicit understandings. Collect results sheets for marking (not summative) to gain awareness of each student’s understanding. Example 6.8: Life in a drop of pond water - Year 5 Outcome: Upper primary students will demonstrate the ability to work scientifically by collecting a sample of local pond water and investigating, through their ability to mount a wet slide and correct use of a microscope, to identify and draw living animals. Standard: Students identify living things and account for observed similarities and differences. Resources: 10 microscopes, 10 small plastic containers, 10 pairs of plastic gloves (one glove per pair), 10 eye droppers, slides and cover slips for each group, powerpoint presentation, worksheet, observational checklist, website: http://www.sciencenetlinks.com/matrix.php Classroom Organisation Reflection and introduction: Students sit at their desks for discussion and instructions. Collection of samples: Students are paired up and the teacher leads the class to the pond while they observe a demonstration of collecting pond water. Microscope and wet slide instructions: Students sit at desks. Microscope use: Students in pairs, work at the microscopes placed on the benches around the classroom.

“THREE LITTLE PIGS” EXPERIMENT: Which materials are best for building? MATERIALS: 5 hair dryers 1 x container of 10 different materials 1 x metre ruler 5 x results sheets for the Pigs METHOD:

1. Teacher plugs in hair dryers and ensure all are on cold 2. Outline safety procedures 3. One by one take the materials out of the container and

place them about 30 centimetres from the end of the hair dryer

4. Blow air for 10 seconds at the material; which materials moved, which didn’t.

5. Place the material in a group: Good for building/ Bad for building

6. Pack away hair dryers and materials 7. Discuss results with the class

If you finish early, try measuring exactly how far each object moves to find out which materials are least suitable for building.

Teacher Procedures/Student Activities Introduction: The lesson starts with a recap of what the students have already learnt. The students will be required to reflect upon their knowledge through answering the teachers’ questions. For example, “What lives in ponds?” and “Why are ponds good for the environment?” (5mins). After reflection, the teacher introduces the lesson that will be taking place that day. The teacher states that the students will be acting as field scientists and stresses the importance of investigation in science. The class and teacher collaborate to form a collective hypothesis. The teacher can start this process when he/she is telling the class what they are going to do during the activity, by asking them questions such as “Do you think anything can live in a drop of water?” and “If so, what do you think might live in it?” The teacher outlines the rules for the field trip (5 mins), which is on a neighbouring property to the school (all parental consent forms were supplied the day before). Safety procedures are ensured such as shoes, hats, and water wise behaviour. Body: The teacher leads the students the local pond and questions students about living and non-living things around the pond. Students record the interactions. The students observe a teacher demonstration of collecting pond water. All students carefully collect a water sample using an eye dropper. The teacher needs to ensure that students collect water near the vegetation. Once the samples have been collected, the students are taken back to class (15-20 mins). Back in the classroom, the teacher presents a power point to the students to remind them about how to use a microscope (e.g., http://www.microscopy_uk.org.uk) and teach them how to mount a wet slide. The teacher also physically demonstrates this procedure. Students are made fully aware about the risks involved with handling glass and microscopes. The teacher briefly outlines the worksheet before students commence the activity (5 mins). While the students are working the teacher monitors the room, observing students work and asking questions such as “How do you know if something is alive?” The teacher gets each group to reflect on their hypothesis by asking: “Did you think anything could live in a drop or water?” and “What did you discover?” Students who cannot locate an animal in their water can move to share with another pair. Students record their findings on the worksheet with illustrations and written comments (15mins). Once students are finished, they must pack up their equipment. Conclusion: Students sit together on the classroom floor with their worksheets. Teacher asks questions about their findings. Students are also asked to make scientific statements about their findings: “What is one thing that you know to be true now?” Teacher asks other questions that will lead the students into the next science lesson, for example: “What would you now write as a hypothesis about pond water?” and “What else would you like to know about animals in pond water?” Extension activity for early finishers: http://www.teachers.ash.org.au/jmresources/pond/life.html#ponds Assessment: Two forms of formative assessment will be employed. First, an observational checklist will be used to determine students’ collaborative interaction, values and attitudes. Second, worksheets will be collected to provide evidence of students learning. Evaluation: The teacher will evaluate the benefits of going to the pond, any other safety hazards that may not have been considered, students’ use of the microscopes and handling of slides, and the appropriateness of worksheets.

Many students have difficulty in understanding density. Density is mass divided by volume (d=m/v). Get a cereal packet – its mass might be say 750g. The cereal will be close to the top of the packet, which is how much volume it takes up inside the plastic bag. Now shake the packet. You will note that the cereal takes up less space, yet you still have 750g of cereal. So it is now more dense than what it was in the first place. If you used a machine and squashed the cereal it may take up only a very small space. It is now even more dense. So the same mass of cereal (750g) is in a much smaller space. Hence, it has the same mass in a smaller volume making it denser than originally observed. You can measure the density by taking the mass and dividing it by the volume. So you can see the smaller the volume the more dense it will be. Water has a density of 1 (e.g., d=m/v; d of water=1g/1mL therefore the density of water=1). Density is affected by temperature; hence boiling water (1000C) is slightly less dense than water at 00C. A few key concepts require further clarification within Example 6.9. Rocks are in three broad categories (i.e., igneous – from the volcano, sedimentary – layers of rocks deposited as a result of erosion, and metamorphic – rocks that have undergone pressure). Erosion can be in four categories, namely, wind, water, wave, and glacial or ice. Constellations are groups of stars, which allows for easy identification (e.g., Leo the Lion or Orion are constellations). Soluble means being able to dissolve (e.g., salt will dissolve in water). However, if you have a bag of salt and a jug of water there will be too much salt to dissolve so there will be a point where it reaches saturation. Example 6.9: More science activities for the primary classroom Set 1 Set 2 Identify rocks and minerals, testing mineral hardness, and use streak plates to test the colours of minerals

HOW CAN I IMPROVE MY PLAN? Evaluating your plan before implementation can provide a way to constructively refine the plan towards more effective teaching. Generally, teachers work collaboratively; they understand the value of interdependence. Many form collegial groups or partnerships as discussion forums for advancing their teaching practices (e.g., troubleshooting issues and bouncing ideas off each other). Another teacher can act as a critical friend, someone who can provide an objective account. Discussing or showing your teaching plans to a valued critical friend can help you to advance your teaching ideas. References Australian Curriculum, Assessment and Reporting Authority (ACARA).
