Curated OER
F = Ma, Inertia, And Action-reaction
Fourth graders investigate Newton's Second and Third Laws of Motion. They determine what makes objects harder or easier to push. While investigating they determine how applying force in order balance out gravity allows things to stay...

Building and Launching Rocket Kits
Students, in groups, build and decorate rocket kits and then launch them.
Curated OER
Rock-A-Bye Pendulum
Third graders use the scientific process to explore the effects of force on an object in motion. They demonstrate that the greater the force applied to an object, the greater the change in speed or direction of the object. They...

Momentum
Students learn the concepts of momentum and its conservation, using the recoil of a cannon as an example. They examine how momentum is a vector, allowing its conservation to be applied to problems in 2 and 3 dimensions.
