In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the... (View More)

A simple experimental apparatus made of rubber band and books is used by student teams challenged with demonstrating the concepts of friction, force, and inertia. This resource is from PUMAS - Practical Uses of Math and Science - a collection of... (View More)

The force of gravity is the focus of this demonstration using a ruler, string and a paper clip. Students observe that the Earth's gravity is always downward toward the center of the Earth. The resource is part of the teacher's guide accompanying the... (View More)
