DAILY LESSON PLAN

Date Class Subject No of student Duration Time Student’s ability

26/8/2013 4 Mawar 1 Science 41 70 mins 10.45-11.55 Weak

Topic : Light, Colour and Sight

Subtopic : 7.1 Synthesising the formation of image by plane mirrors and lenses

Objectives : Understanding the step to draw the diagram when the ray of light pass through the convex lenses and concave lens Understanding the characteristics of image formed by the convex lens when distance between the lens on the object varies.

Learning Outcome: By the end of this lesson, students should be able to:

a) Draw the ray diagram when the rays of light pass through the lens.b) Understand the step to draw the ray diagramc) Draw the ray diagram when distance between the convex lens on the object variesd) State the characteristics of image formed by the convex lens when distance between the lens on the object variese) State the characteristics of image formed by the concave lens

Scientific and Thinking Skills : Observing, identifying, classifying, comparing and contrasting, analyzing, reasoning

Pre-requisite knowledge : Students should be already able to:

a) state the characteristics of images formed by a plane mirror,b) label the raw diagram when the parallel ray pass through the lensc) State the rules to draw the Ray Diagram

Page 2: 7.1 Lp Convex Lens From Various Distance

Teaching and learning approaches : 1) Set induction

a) State learning outcome: Student know what they will get for today’s lessonb) Constructivism approach: -Student try to analyze which one is the convex lens and which one is the concave lens

-Students try to observe and analyze the image formed by concave and convex lens on their own

- Students try to make conclusion about the image formed by the concave lens and convex lens

2 ) Development phase:

a) Interactive approach : Student observe and analyze the image formed by the convex lens from the distant object\

b) Promote analytical thinking : Why human can see the things in surrounding are upright although the images formed on the retina are

upright?

c) Guided learning and expository approach in the developmental phase

Teaching aids / technology : 1. Power point Slide- Aid in deliver the content

2. Whiteboard, ruler, marker, and Power point slide - Aid in drawing the ray diagram

3. convex and concave lens, , spectacles, torchlight – Student can observe the formation of the image

through lens in real

Scientific attitudes and noble values : Enthusiasm in learning, cooperative, Gathering information with patient, confidence, respect,

Appreciating scientist’s contribution to human, appreciating God’s creation , Believe in God

activities

Induction

Phase

[ 10 minute]

Teacher check their homework

State the learning outcomes.

Convex lens

Analyze the characteristic of the image formed when looking at the near object through the convex lens, concave lens , on the whiteboard

Appreciating scientist’s contribution

to human

Motive: Teacher want to make them

appreciate other’s contribution

understand the concept and apply it

in real life

Teacher checks their homework and ask them to keep all other book in their bag.

Teacher tells them to stress more on this topic

since this topic always come out in SPM question.

Teacher let them to read the learning outcome

Give analogy on how to remember the

differences between convex and concave.

Teacher ask:

What can u see???

Upright or upside down???

Magnified or diminished? Real or virtual?

Teacher use the torchlight and the lens to show

the image on the board and the application of the

lens

Scientists have contributed many optical

instruments that benefits human such as slide

projector, microscope, telescope, camera,

Student put

the homework

on the table.

1. Answer the

question given

by the teacher

Tools

Lens ,torchlight,

black paper

Whiteboard

Moral value

Respect, compare

and contrast

Appreciating

scientist’s

contribution to

human

Page 4: 7.1 Lp Convex Lens From Various Distance

• Describe image formed

magnifying glass.

Contrast between real and virtual image

Teacher ask:

1. What u can see? Any idea about it?

2. Can u guess this is convex lens or concave

lens?

3. Try to look the board using your concave

lens and convex lens.

4. Describe image formed

5. Can u make the conclusion?

Spectacles

Development

phase

(± 20 minit)

Show the formation of the imageWhen the distant object pass through the lens

Teacher asks the student to come and observe

the characteristics of the image formed from the

distant object ( school building)

Teacher tell them on how to find the focal length

State all the characteristics:

• Image formed?

• Answer the previous question:

Why human can see the things in

surrounding are upright although the

Student listen

and answer

Black paper,convex

lenswhiteboard,

marker

Moral Value

Appreciate the

creation of God

analytical thinking

Page 5: 7.1 Lp Convex Lens From Various Distance

Rules to step to draw the ray diagramConvex lens Concave

images formed on the retina are upright?

Those who can answer can get the reward

Answer: Brain will automatically correct this

Appreciate the unique of God’s creation.

Teacher tells them that they have to master the

rule and the aim of ray diagram.

There are millions of ray of light, come from

many directions.

But in this lesson, u have to learn and remember

only three direction

Teacher ask them to read the step

Teacher asks for volunteer to draw in front of the

class

Teacher randomly call their name to draw in front

Student look at

the textbook

while listen to

teacher’s

explanation.

Students come

in front and

draw.

2nd

Development

phase

30 minutes

• Draw the ray diagram when distance between the convex lens on the object varies

• State the characteristics of image formed by the convex lens when distance between the lens on the object varies

In the previous lesson , student have learn the

rules to draw the diagram,

Still remember the rules?

Teacher asks for volunteer to draw in front of the

class

Student try to

draw on the

whiteboard

Power point Slide

Whiteboard

Page 6: 7.1 Lp Convex Lens From Various Distance

State the applications of the lens

Closing and

Reflection

phase

(± 5 minute)

1. Evaluation

2. Do summary

3. Ask them to do the

homework

4. Experiment in next class

5. Dismiss the class by saying

thank you

Evaluation :

Where we must put the object if we want to use

the convex lens as magnifying glass?

• Between F and optical centre

Any question???

Homework : Draw all the diagram on page 156 in

their note book

Teacher asks them to finish the worksheet.

Be prepared before experiment

Response to

the question

asks by the

teacher

Handout

Moral value

Be prepared,

hardworking,

analytical thinking,
