In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

Students design and create their own air-powered rockets, in this hands-on activity.

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can
