To help students understand and describe the motion of an object. A satisfactory description requires that measurements be made and that the motion be described using equations or graphs.
Toys of various types that move such as the following:
Wind-up Walking Toys
Battery Powered Cars
Nerf Dart Gun
Hot Wheels Car and Launcher
1. Have the toys out for students to see.
2. Group students and ask them to experiment with several of the toys, select one, and write a description of its motion.
3. When all groups have written their descriptions, select a student and read a description from one of the other groups. Have the student try to predict the position of the object at some later point in time based on the description.
4. Repeat this with other groups descriptions.
Students should have the most success with objects that move in a straight line at a constant speed. Suggest that starting a study of motion with this type of motion makes sense. Also point out that it is very difficult to write a good description of motion in words. Suggest
that it is possible to make much more accurate predictions about the motion of an object if information about its position and time are known and presented as a graph or in the form of an equation.
