Compare mass and gravity in hands-on gravity well experiments!

Blending physics and astronomy, students learn about the gravitational pull of objects in space—including our own planet Earth!—and how more mass creates deeper gravity wells. But they won’t have to take a textbook’s word for it. Hands-on gravity experiments offer visible proof!

Start by placing the center weight on the covered frame and roll golf balls along the edge until they orbit the center weight. Students ask and answer their own questions about changes to gravity and its impact on the orbiting balls. Creativity abounds as students imagine the center weight as the sun and golf balls as the planets that orbit it. Then reward budding curiosity by allowing students to test the gravity wells of weighted objects found in the classroom.

The durable ABS frame features hook-and-loop fastener straps to keep the spandex and cordura cover taught. The steel center weight is powder-coated for longevity and features a beveled edge that nests easily into the cover. Included lesson direction is adaptable for Grades K-4 and 5-8. See contents list below. Frame is 40”H x 40-1/2” dia; 14 lb. Weight is 2-1/2”H x 4” dia; 7-3/4 lb. Recommended for Elementary and up.
