1 ST.XAVIER S INSTITUTE OF EDUCATION MUMBAI LESSON PLAN CONTEXT Name of the Student Teacher: Cardoza Adalbert Roll No: 5 Name of the topic: Reflection of light Internship School: St. Andrew's High School Subject: Pedagogy I: Science Standard and Division: VIII-B Plan Number 1 Pedagogy II: Choose an item. General Lesson: 26/Co Teaching: Choose an item./theme based: Choose an item. Theme: Date : Time: 8:15am - 8:55am Entry Behaviour: The pupil is aware about the source of light, mirror properties of transparency and non transparency Correlation: Internal correlation with life External correlation with life Content Organisation - Topic: Reflection of light The laws of Types of /Core Components: Content essential to nurture national identity INSTRUCTIONAL OBJECTIVES A. FOR LESSONS Remembering The pupil defines the term The pupil identifies the different rays of The pupil lists the different images formed in a mirror The pupil recalls the diagram of

2 Understanding The pupil illustrates how an image formed in a plane mirror is in its exact location The pupil compares angle of incidence and the angle of The pupil distinguishes between and of reflected light The pupil estimates how an image is formed The pupil explains the concept of irregular Applying The pupil implements the use of in a periscope The pupil discovers why the moon shines so bright B. CORE COMPONENTS/VALUES The pupil develops awareness of the core component content essential to nurture national Identity The pupil suggest means as how would their behaviour towards others reflect traditional Indian values C. ASSIGNMENTS Creates The pupil creates a chart depicting various images formed in a plane mirror METHODOLOGY TO BE FOLLOWED: For the Lesson: Questioning and discussion For the core components Questioning and discussion EVALUATION STRATEGIES TO BE FOLLOWED For the Lesson: Explanation and give reasons TEACHING AIDS: Torch, mirror and lenses REFERENCES: Home Content What is Optics?

3 Experience: Set Induction The teacher asks one pupil to make a paper ball and throw it on the board and asks the class what did you observe? Teacher asks the pupil what happens when you throw anything towards a hard surface does it go inside it? It comes back Link statement Now, in a similar way we will see how light comes back on contact with a hard surface Statement of Aim SubUnit 1 Concepts Laws of Wrong conceptualisation So, today we will be doing the chapter of light, in which we will doing the laws of and types of Teacher asks the pupil what happens when you see yourself in front of the mirror. What is that concept called? Teacher shows an image of a day sky and asks the pupil why does the sea appear blue during the day and black at night? Is the colour of water blue? Teacher elicits the answer from the students and states that the colour of the sky is reflected in the sea that is a reason the sea is blue Teacher asks the students what is required for to take place Teacher asks the pupil doesn t take place on a hard surface? Depending on the answer the teacher states that it is not always that light requires a transparent medium it also can reflect through any medium but the given out is minimum Teacher asks the pupil what happens when a candle is kept in a dark room? Teacher asks the pupil when you throw a ball on the wall do you know exactly where is it going to fall? Similarly, when light falls on any surface we do not know exactly where is it going to fall??????? Teacher elicits the meaning of incidence from the students and puts up the definition of incident ray on the board Reflection of light Reflection The surface has to be transparent Diagram No An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. Thereflected

4 Teacher asks the pupil what happens once the ball hits the surface? Does the ball too get a particular direction after been thrown from the wall? That direction is known as the ray of (meaning to move backwards) Teacher draws up the rays of incidence and on the board Teacher asks the student what is the meaning of normal called? Teacher states an imaginary line can be drawn between the ray of incidence and ray of it is called as the normal Teacher asks the pupil why is this line called as the normal? Teacher elicits the meaning of normal from the students i.e. means equal and puts up the definition of Normal on the board ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface. Comes back Yes The normal line divides the angle between the incident ray and the reflected ray into two equal angles. Sub Unit2 Laws of Reflection Teacher asks various questions with respect to the diagram what is the ray that falls on the surface called? What is the ray that reflects from the surface called? and puts up the laws of on the board Teacher asks for examples as to where do we see this concept of in our houses and in our day to day life 1.The law of states that the incident ray, thereflected ray, and the normal to the surface of the mirror all lie in the same plane. Relevant questions for deriving the laws of 2. The incident ray and reflected ray lie on the opposite sides of the normal 3.. Furthermore, the angle of is equal to the angle of incidence. Both angles are measured with respect to the normal to the mirror

Teacher elicits the answer of regular and irregular with respect to A glass image and shadow and puts up the definition on CB All irrelevant questions please avoid Mirror-regular Surface of

5 SubUnit3 2 Types of Teacher asks the pupil what is the difference when you stand in front of the mirror and in front of a wooden plank? Teacher asks the pupil can you see yourself in the mirror when the room is dark? Teacher asks the pupil why we require light. Teacher asks the students what is shadow? When can you see it? Teacher elicits the answer of regular and irregular with respect to A glass image and shadow and puts up the definition on CB All irrelevant questions please avoid Mirror-regular Surface of water-irregular In a mirror we can see our image but in a wooden plank we cannot see No To see It s a shade of light. Reflection Action Summary So, today we have learnt the concept of, what does mean in terms of behaviour How would your behaviour reflect your family values? How would you as an individual reflect your national identity in this changing society? How would you interact with the foreigners you see in our country? The of light can be roughly categorized into two types of : specular is defined as light reflected from a smooth surface at a definite angle, and diffuse, which is produced by rough surfaces that tend to reflect light in all directions Evaluation So today we have learnt the topics on The laws of and Types of Write the laws of, explain the same with the help of a ray diagram What happens when a ray of light falls normally on the surface of a mirror

6 Assignment Give reason when a glass tube is placed in water it appears slanting Distinguish between regular and diffuse Create a chart depicting various images formed in a plane mirror ENTER Formatted: Tab stops: 1.75 cm, Left INCLUDE SUGGESTIONS GIVEN DR.VINI SEBASTIAN 21/9/17

8 C.B Work Laws of Types of relection he law of states that the incident The of light can be roughly ray, thereflected ray, and the normal to the categorized into two types of surface of the mirror all lie in the same : specular is defined plane. Furthermore, the angle as light reflected from a smooth surface at of is equal to the angle of a definite angle, and diffuse, incidence. Both angles are measured with which is produced by rough surfaces that respect to the normal to the mirror. tend to reflect light in all directions Supervisor s Feedback
