A. Measure the speed of a cockroach.

Speed equals the distance traveled per unit time. Place the ruler on the table. Get the cockroach to run along the ruler in a straight line. Time with a stop watch how long it takes to run about 30 cm.

Speed (cm/sec) = Distance (cm)/ Time (sec)

How fast would your cockroach be if it were human size?

Human speed (miles / hour) = cockroach speed (cm/sec) X 4

 B. Our questions:

1. When your animal moves forward which parts move?

2. When an animal moves forward which parts push?
How do these parts push the animal forward?
How do these parts push the animal upward?

3. When an animal moves what slows down its movement?
