We are in our newest Science unit - Balance and Motion! We learn a lot about these concepts in fun, interactive, and hands-on ways! The essential questions for this unit are:
-Why do things move?
-What are different ways to change the motion of an object?
-What is balance?
During this unit, students explore stable (balanced) and unstable systems, using counterweights to change the center of mass of the systems. They explore two types of motion--spinning and rolling--first through trial and error, and later through systematic explorations. Students begin to develop a sense of variables, which they control to produce desired outcomes.
Some key vocabulary terms:
axle
balance
counterweight
motion
rotate
slope
sphere
spin
stability
wheel
