Students investigate their tracks to determine the number of footsteps it takes to travel the entire length of their bodies. Then they determine the taller of two children and the shorter of two children with their tracks. Students also...

Students, using paper and water, make tracks and record the time needed to make them. They compare tracks made walking and running to determine the speed of the animal.

Students calculate the stride length of a walking or running animal. They use scale models of dinosaurs to calculate the leg and stride length of the animals.

Students discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.
