Ward's® Gravity and Orbits Lab Activity

Enough Materials to Construct Five Sets of Two Models

• Includes a teacher's guide

Students investigate the effect of gravity on a moving body, then determine the relationship between a celestial object’s period of revolution and the force pulling on the object, by constructing two simple models in a two-part lab activity. You will receive enough materials for five setups, a teacher’s guide, and student copymasters.
