WEEK 3 Tuesday Lesson 1

INTRODUCTION TO ENERGY

Students present to class what they found about their energy form.

Students to note the main points about each energy type as they are

presented.

Learning Intention: Know the different forms of energy.

3. Give students 5-10 minutes to finish research/discuss with partner what they are going to share with the class.

4. Have students draw up a table in their book to record notes for each energy type as they go.

Form of

Energy Definition

Examples of where

this form of energy

can be found

Can this form of

energy be transformed

into a different type of

energy?

Any other

interesting facts

about this form

of energy?

5. Each group share what they found about their energy. Students should have a comprehensive table covering all of the

energy types by the end of the lesson. If presentations so not get finished, complete in next lesson.

6. Check questions pg 56.

7. IF TIME: Introduction to Energy

- Emphasize that energy makes things happen: how do we feel when we have lots of energy? How are new batteries

different to flat ones? Footballs can fly through the air by us kicking it. We can burn wood which creates a bright flame

and lots of heat. Energy makes things happen.

- Discuss the definitions of energy that students came up with in the group research task. Energy is

something that has the ability to cause a change or make something happen. Scientists call this the “ability to

do work”.

- We cannot see energy or weigh energy or keep it in a container. We only see what energy can do as nothing will move

or happen without energy.

- Energy is measured in Joules


Introduce energy: definition, unit of measurement, importance of energy in our daily lives (plants, eating, cars, electrical energy for power, torch and batteries etc etc.

KINETIC ENERGY

Remind students of what kinetic energy is, introduce KE=1/2

mv2 equation, do some practice questions.

LEARNING INTENTION: To understand that kinetic energy is the energy of a moving object.

1. Owe this class chocolate frogs (those who were present in Wednesday’s lesson)

2. Warm up activity – “What is energy” revision (see how much they can do by remembering, use notes to help you)

- Write the definition of energy.

- Match a couple of definitions with energy type.

3. Kinetic energy

- Kinetic energy is the energy that is possessed by a moving object

- Kinetic energy depends on mass and speed

- It is possible to calculate the KE of an object using the formula KE = ½ mv2

- Kinetic energy can be transferred from one object to another: visual examples using 2 balls, dominos and talk about

playing pool.

4. Practice questions – using KE = ½ mv2 equation

- Do question 1 as an example; do question 2 with student input. May have to explain what squared means.

5. Go through the solutions to the worksheet

6. Forms of energy that are easy to identify

- Talk about how some forms of energy are really easy to “see”

- Brainstorm – where can we easily find heat energy, light energy, sound energy

- Does everything have energy? We have talked about how everything around us has energy, but what about door,

books on shelf – do they have energy. Not moving, not making any sounds, not hot, not producing any light?


KE extension worksheet (for those who understand the maths and finish the first questions easily.

Move onto gravitational potential energy

Students can begin making a ‘glossary’ of the important words that they have learnt so far.

ENERGY TRANSFER AND TRANSFORMATION

Energy can be transferred to different objects and transformed

into different forms of energy, introduction to chemical energy.

LEARNING INTENTION: To understand that energy can be transferred and transformed.

7. Warm up activity – Kinetic energy revision (see how much they can do by remembering, use notes to help you)

- Write the definition of kinetic energy, examples of where we can find kinetic energy

8. Watch OK GO video clip

9. Energy transfer

- Energy can be transferred from one object to another. Examples: kicking a ball (kinetic energy from leg moving is

transferred (passed onto) the ball which causes the ball to move

- Heat energy is also a common one where we see energy transferred from one object to another.

- Saw in OK GO video a lot of this … things were bumping into other things to make them move and continue on the

chain reaction.

10. Energy transformation

- Energy can be transformed from one form of energy to another form of energy. Sometimes several energy changes

happen all at once.

- Examples: talk about energy rotation prac, rubbing hands, fire, phone, car, toaster.

11. Chemical energy

- A type of potential energy.

- Chemical energy is one form of energy that we can look at energy transformation.

- Chemical energy is the energy that is stored in chemical bonds in molecules. When the bonds are broken, energy is

released in a different form.

- Examples: food (chemical to kinetic … gives us energy to move and do things), batteries, wood, petrol, paper.

12. Introduction to Practical

- To find out how much energy is released when a small piece of food burns.

- Burning food: chemical to heat (+light+sound). When we convert the chemical energy into heat energy, we can use it

to heat up water as a way to measure how much energy was released.

- Prac report required.

13. Time remaining: Finish check questions pg 56, Pg 63 Q1, 5, 7, 8


Check questions pg 56, Pg 63 Q1, 5, 7, 8

ELASTIC AND GRAVITATIONAL POTENTIAL ENERGY

What are elastic and gravitational potential energy, elastic potential

energy practical.

Learning Intentions: To define and give examples of gravitational and elastic potential energy.

- Warm up activity: quick quiz on the screen, remind students of what potential energy is.

- Gravitational Potential Energy

- GPE is energy that is stored in an object when it is above the ground.

- Hold up textbook – we know it has GPE because if you take hand out from under the textbook, it will fall. When

holding, it wasn’t doing anything right at that point but could be used in a later time.

- Depends on mass (demonstrate with textbook and paper), height above the ground (demonstrate with two

textbooks) and gravity.

- Practice question – students to come to conclusion that as an object gets closer to the ground it has less GPE,

where did that energy go? It gets TRANSFORMED into kinetic energy.

- Elastic Potential Energy

- Energy that is stored in an object that can be stretched or squashed.

- Potential energy – not using the energy while it is stretched but has energy that is ready to be used at a later time

(it when you let it go)

- Introduce practical that is going to investigate Elastic potential energy – read through and explain.

- Potential Energy Practical

- Students to complete practical and associated questions.

- IF TIME: Check questions textbooks

- Science World 8 Pg 63
