The tabletop-sized gravity well allows for easy transport, so busy learners can take their gravity experiments around the classroom! Place the weighted resin ball (1-3/4" dia) in the center of the gravity well, then roll the differently sized marbles around the edge to represent the orbits of different planets. As students peer into the cosmos and learn about gravity in the solar system, they develop observation skills while getting hands-on experience with experimentation.

Easily stretch the spandex cover over the foam frame (20" dia x 6"H) and secure with hook-and-loop fasteners or disassemble it for compact storage. Keep everything organized together with the convenient storage bag. Kit accommodates 3 students. Set of 4 accommodates 12 students. Recommended for Elementary and up.

CHOKING HAZARD (1). Not for under 3 yrs.

Next Generation Science Standards*:

  • 5-PS2-1: Support an argument that the gravitational force exerted by Earth on objects is directed down.

  • MS-ESS1-2: Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.

  • MS-ESS1-3: Analyze and interpret data to determine scale properties of objects in the solar system.

  • MS-PS2-4: Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

  • MS-PS2-2: Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.

  • HS-PS2-4: Use mathematical representations of Newton’s Law of Gravitation to describe and predict the gravitational forces between objects.

  • HS-PS2-1: Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.

  • HS-ESS1-4: Use mathematical or computational representations to predict the motion of orbiting objects in the solar system.
