Fourth graders conduct experiments to identify the center of gravity. For this gravity lesson, 4th graders do two hands-on experiments to increase their understanding of this concept. This self-discovery lesson provides students with the...

Learners identify an object's center of gravity. In this physics lesson, students use two metal forks, modeling clay, toothpick, and a drinking glass to balance the forks on the glass. Learners use the angle of the forks to spread the...

Students calculate acceleration due to gravity.
