Product Description
These activities are a nice addition to a study of forces and motion. In the first one, students use BBs and pullback cars to demonstrate how when the car goes forward, it's pushing backward on the ground.

In the second, students use rubber bands to demonstrate and measure equal and opposite forces. Extension ideas are provided for digging deeper to help solidify the concept for students. Most students have the sense that only people can exert a force such as a push--and don't realize that walls, tables, the ground, etc can push things too. This surprising fact is fundamental to understanding Newton's third law.

PLEASE NOTE: these experiments is part of the unit bundle sold in my shop: Force, Motion, & Energy Bundle—Video and Written Instructions
