LESSON TEMPLATENAME OF THE TEACHER TRAINEE : DEEPIKA RAJ C STANDARD: VIII FNAME OF THE SCHOOL : GOVT.HSS PALAYAMKUNNU STRENGTH :SUBJECT : PHYSICS DURATION: 45UNIT : MOTION AGE : 13+TOPIC : RELATIVE MOTION DATE :

CURRICULAR STATEMENTPupils develop an understanding on the concept `Relative motion through experimentation, observation and discussion and also develop an ability to use the acquired knowledge in another situations CONTENT ANALYSIS TERMS : State of rest, State of motion, Reference bodyFACTS :i. A passenger in a moving bus is in state of rest with respect to the bus and in state of motion with respect to the rodii. A child standing in a field is in state of rest with respect to the ground but in the state of motion with respect to the suniii. A crow sitting on a cow is in state of rest with respect to the cow and in state of motion with respect to the groundiv. A book on s rotating table is in state of rest with respect to the table and in state of motion with respect to the groundv. The baby of kangaroo is in the state of rest with respect to the mother and in state of motion with respect to the groundvi. The earth is not seems to be moving with respect to us but seems to be moving when watching from other planetsvii. All creatures on earth are in state of motion with respect to the sun but not in motion with respect to the earth

CONCEPTS:i. Reference body: Reference body is the body with respect to which the state of rest or state of motion of another body can be describedii. State of rest: If the position of a body does not changes with respect to the reference body then the body is said to be at restiii. State of motion: If the position of a body changes with respect to another body then the body is said to be in state of motion

LEARNING OUTCOMETo enable the pupil to1. recalling terms and definitions of state of rest, state of motion and reference body and recognizing the same for developing factual knowledge2. explaining the process and definitions of state of rest, state of motion and reference body for developing conceptual knowledge3. conducting practical works on the techniques of finding out the state of a body with respect to the reference body for developing procedural knowledge4. validating the process of defining state of rest, state of motion and reference body for developing meta cognitive knowledge PRE-REQUISITESThe pupils already knows that sometimes they are in motion and sometimes they are t rest TECHING LERNING RESOUECESMATERIALS: Activity cards, Sketch pen,A-V AIDS : Laptop CLASSROOM INTERACTION PROCEDUREEXPECTED PUPIL RESPONSE

INTRODUCTION1. Have you ever travelled in a bus?2. Do you like to see sites while travelling in a bus?3. Did you feel that the trees and hills are running backward when we move forward?4. Did your companions are seem to be running backward?5. Why did you feel like this?So today through this class we will discuss about this. Teacher starts the class.

PRESENTTION Teacher divides the whole students in to four groups and name them as NEWTON, EINSTEIN, GALILI, KEPLER and ask them to do the following activities.

ACTIVITY NO:1 Teacher shows a video of a group of person travelling in a bus. In the video a person standing outside the bus is waving his hands towards a passenger inside the bus. Teacher instructed the students to watch the video and to answer the following questions by discussing in the group. DISCUSSION CLUES1. What do you saw in the video?2. Whether the position of the passenger changes with respect to the man standing outside?3. Does his position changes with respect to the companion in the bus?

CONCEPTS TO BE CONSOLIDATEDThe position of the passenger changes with respect to the road but does not changes with respect to the bus

ACTIVITY NO:2 Teacher shows a video of a crow sitting on a cow grazing in a field. Teacher instructed the pupils to watch it and to answer the following questions by discussing in the group.

DISCUSSION CLUES1. What do you see in the video?2. Does the position of the crow changes with respect to the cow?3. Does the position of the crow changes with respect to the ground?

CONCEPTS TO BE CONSOLIDATEDThe position of the crow changes with respect to the ground but doesnt changes with respect to the cow

ACTIVITY NO: 3 Teacher shows a video of solar system to the students. Instructed them to watch it and to answer the following questions by discussing in the group.

DISCUSSION CLUES1. What do you see in the video?2. Do we feel that the earth is moving with respect to us?3. Does the earth is seems to be moving when watching from other planets?

CONCEPTS TO BE CONSOLIDATEDWhen observing from earth the earth is seems to be not moving. But the earth actually moves.

GENERALISATION From the above activities it is clear that a body is said to be in state of rest or state of motion only with respect to another body. When the body in reference changes the state also changes. Reference body is the body with respect to which the state of rest or state of motion of another body can be described

If the position of a body does not changes with respect to the reference body then the body is said to be at rest

If the position of a body changes with respect to another body then the body is said to be in state of motion
