# Measure Speed of the Ant

## Objective

To measure distance, time and speed.

## Introduction

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.

## Apparatus

Thread, scale, watch

## Procedure

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.

## Discussion

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.
