Lesson Planning of Speed
Subject General Science
Grade 4^{th}
Students` Learning Outcomes
 Define speed and give its relation with distance.
Information for Teachers
 Speed involves two things: distance covered and the duration of time.
 Distance covered in unit time is called speed.
 A fast speed objects covers a specified distance in less time than a slow speed object.
Material / Resources
Two tennis balls, writing board, chalk / marker, duster, textbook
Introduction
 Ask the students:
 When you were walking in the street, a cyclist passed by you; who are faster, you or the cyclist?
 Then ask have you ever seen the speedometer of a motor bike or a car?
 Inform them that the speedometers are used to measure the speed.
 Inform the students: When you come to school, you cover some distance between your home and school. Then ask:

 How do you cover this distance? (Expected answer may be as; on foot, on bicycle, car or bus).
 How long does it take you to cover this distance?
 How can you cover this distance faster? (Expected answer may be as; on foot, on bicycle, car or bus). (Inform them: A fast speed object covers the specified distance in less time)
Development
Activity 1
 Ask two students to go from one end of the classroom to the other.
 Ask one student to cover this distance by walking and the other by running.
 Ask: Who reached the first? And why done so?
 Draw their attention to the fact that the greater the speed of the object the shorter is the time taken to cover a certain distance.
Activity 2
 Mark two lines on the floor, one is the starting line and the other is the finishing line.
 Place two tennis balls A and B side by side on the starting line.
 Then ask a student to push both the balls towards the finishing line with different forces.
 After this demonstration, ask the students:

 Which ball reached the finishing line earlier?
 Which ball moved faster?
 Draw out the conclusion than an object with greater speed covers a certain distance in shorter time.
Activity 3
 Take your students to a playground.
 Ask two students to start running in the same direction at the first clap and stop running at the send clap.
 Then ask:
 Which student covered a longer distance in the same time?
 Which student ran faster? (Expected answer may be as; a high speed object covers a longer distance in a certain time)
Sum up / Conclusion
 Ask the students:
 What we have learnt from today`s lesson? And write on the board the following conclusions from the students` answers.
 The distance is measured by measuring length between the specific points.
 A faster object covers a specified distance in less time than a slow speed object.
 A faster object covers a longer distance in less time as compare to a slow one.
Assessment
 Teacher will show some pictures (or cut outs) as given below to the students and ask the following questions:
 Look at the pictures below.
 Which item is the fastest and which is slowest?
 In the blocks given below, put the number of suitable pictures.
 Involve the students in solving the questions given at the end of chapter / unit in textbook
Follow up
 Discuss the speed of different things in everyday life with your class fellows and enlist them in order of decreasing speed of objects.
