In this interesting science experiment video about forces, Jared uses balloons to show us that a force is a push or pull. He also explains that the force of air is what makes a jet take-off.
This video satisfies the K-PS2-1 requirement for kindergarten proficiency.
Students who demonstrate understanding can:
K-PS2-1. Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
