|Balance and Motion Overview
We live in a dynamic world
where everything is in
motion, or so it seems. But
not everything is moving the
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
FOSS EXPECTS STUDENTS TO
• Measure linear distance using standard metric units.
• Explore concepts of position, balance, counterweight, and
• Observe and describe systems that are unstable and modify
them to reach equilibrium by changing the position of
• 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
• Observe and compare rolling systems with different-sized
• 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.
