Lesson Plan of Speed
General Science Grade IV
Students’ Learning Outcomes
· Define speed and give its relation with distance.
Information for Teachers
· Distance covered in unit time is called speed.
· A fast speed objects covers a specified distance in less than a slow speed object.
Material / Resources
Two tennis balls, chalk, textbook
Worm up activity
Ask the students:
· When you were walking in the street, a cyclist passed by you. Who is 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?
(Students’ response: on foot, on bicycle, car or bus). How long does it take you to cover this distance?
· How can you cover this distance faster? By travailing on bicycle, car or on foot?
(Inform them: a fast speed object covers the specified distance in less time)
· Ask one student to cover this distance by walking and the other by running.
· Ask: who reached first? And why?
· Draw their attention to the fact that the greater the speed of object the shorter is the time taken to cover a certain distance.
· 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 the different forces.
· After this demonstration, ask the students: which ball reached the finishing line earlier?
· Which ball moved faster?
· Draw out the conclusion that an object with greater speed covers a certain distance in shorter time.
· Repeat the activity with different pairs of students.
· 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 second of clap.
· Then ask: which student covered a longer distance in the same time?
· Which student ran faster?
(Students’ response: A high speed object covers a longer distance in a certain time.
Sum up / conclusion
Ask the students: What we have learn t from today’s lesson? And write on the board the following conclusions from 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 compared to a slow one.
· Teacher will show some pictures (or cut outs) as given below to the students and ask the following questions:
· Look at the picture below, which item is the fastest and which is slowest?
· In the block given below, put the number of suitable pictures.
