Summary:The Pull of the Planets is part of a thematic series of lessons highlighting the Juno mission to Jupiter. It is a traditional hands-on activity that models how gravitational forces can keep planets and asteroids in orbit within the Solar System. Using stretchable fabric help in place with an embroidery hoop, students work with spheres of various materials to explore how mass and size affect the strength of gravitational forces. Background materials, including a materials sheet, aid teachers in organizing this activity.
