1. Take a stone, tie a thread to it and whirl it with your hand. Observe the motion of the stone. We see that the stone moves along a circular path.

Lesson plan version 1.1 activities
1. Let us observe a bike, a cycle and a bullock-cart as they move on the road. Which of these takes the shortest time to cover a certain distance? The bike is the fastest as it takes least time. The bullock-cart is the slowest as it takes longest time. The cycle moves at a speed between that of the car and the bullock-cart. A fast moving object has high speed and a slow moving object has slow speed. Now, what about a car or train?
2. Let us give a cricket ball to a group of four friends and ask each of them to throw the cricket ball from a given point. Mark the point up to which each of them throws the ball. Measure the distance thrown and discuss the speed of the ball.
3. Let us organise a toy car race to understand the concept of speed. Divide the class into 5 groups. Draw a line at the starting point . One from each group should roll the toy car along the ground. Another should note the time taken by the car from the instant the car crosses the line to the instant it stops. Measure the distance. Calculate the speed of each car and record it.
OR
A race among students themselves can be conducted. Class assistant can record the time and then each student can calculate their own speed.
