Measure Speed of the Ant
To measure distance, time and speed.
The distance of a straight line is usually measured with a scale. This activity train students on how to measure distance of a curved line.
Thread, scale, watch
Watch an ant moving on the floor. Keep marking ant position as it moves. Measure the distance it travels and the time it takes to travel this distance. Calculate the speed of the ant.
The distance of a curved line can be measured by using a thread and a scale. The time is measured by the watch. The speed is calculated by dividing the distance by the time. The students can also be introduced to the concepts of average speed, instantaneous speed, displacement, and velocity.
