Gravity: Falling for Cue (Gr. 6-8)


In this lesson, students will work in pairs to create a model that demonstrates the role of gravity on motions within the solar system. Gravity will be represented as a string between a stationary object and Cue. The students will analyze the effects of increasing the mass of Cue and changing the distance from the stationary object on the strength of the gravitational attraction.


  • Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system
  • Develop an understanding on the effect of distance and mass on the force of gravity
  • Use Cue as an object in orbit, connected by a string to a stationary object
  • Implement loops and/or events in their program
