FOSS Module Summary

Module Summary – Balance and Motion (CA Ed.)


We live in a dynamic world where everything is in motion, or so it seems. But not everything is moving th same way. Some things move from one place to another. Other things go around and around in a rotational motion. 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.


  • Measure linear distance using standard metric units.
  • Explore concepts of position, balance, counterweight, and stability.
  • Observe and describe systems that are unstable and modify them to reach equilibrium by changing the position of counterweights.
  • Observe that objects fall to the ground due to the force of gravity unless something holds them up.
  • Discover different ways to produce rotational motion using forces (pushes and pulls).
  • Construct and observe toys that spin, and explore and describe some of the variables that influence the spinning of objects.
  • Observe and compare rolling systems with different-sized wheels.
  • Explore and describe the motion of rolling spheres.
  • Investigate sound pitch and volume in terms of vibration.
  • Investigate magnetic force and observe how it can make things move at a distance.
  • Know examples of how tools and machines are used to make things happen.
  • Make predictions of motion events based on patterns.
