FOSS Third Edition Balance and Motion

We live in a dynamic world where everything is in motion in different ways, as objects, move from one place to another, vibrate, or rotate around and around. Still other things are stationary, stable for a time, balanced on a thin line between stop and go. These are the global phenomena that students experience in the Balance and Motion Module.

Students will:

  • Create and use representational models to demonstrate stable balanced systems.
  • Plan and execute examples of stable balanced systems.
  • Discover different ways to produce rotational motion.
  • Construct and evaluate toys that demonstrate spinning, and explain how they operate.
  • Design runways to control or change the motion of marbles.
  • Communicate observations and compare stability and motion, using precise vocabulary.
  • Plan and carry out investigations with sound and with magnetic force.
  • Analyze and interpret observational data.


  • Investigation 1: Balance
  • Investigation 2: Spinners
