This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this activity, learners experiment with gear motion to understand how gears work to change the amount of force, speed, or direction of motion in machines.

Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.
