The Tortoise And Hare Race

Many students face the problem of interpreting graphs for kinematics. Very often, they think a line parallel to the time axis of the s-t graph represents movement of an object with constant velocity. In actual fact the object is not moving. In order to help the students to figure that out, the famous story of 'The tortoise and the hare race' can be retold with slight modification. For the hare that sleeps throughout the race its displacement from the starting point is always a constant whereas the tortoise moves with a constant velocity. With this method, it should be more interesting and meaningful to learn and understand the graphs. It is not too difficult to understand various s-t and v-t graphs by creating various interesting stories that students like. Spice up your teaching with various stories and illustrations and you will find that you can win more fans this way.
