This is a great tool to illustrate the variables of gravity and mass and how they relate. Students will thoroughly enjoy making predictions then manipulating the variables then see the outcomes.

The asset relates directly to Earth, Moon and Sun interaction, but could be used as a starting point for discussion about other heavenly bodies. The manaipulative allows students to understand the concepts of gravitational pull and how it affects motion in our solar system.
By Reviewer 3
Great site to illustrate how gravity plays a role in the location and motion of the planets and the sun, but the site does not address any of the three standards completely.
