In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity related to flight, learners conduct two simple tests to explore how lift works.

When baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

"Exploring the Universe: Objects in Motion" encourages participants to explore the complex but predictable ways objects in the universe interact with each other.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

This is an activity about Newton's First Law of Motion - a body in motion tends to stay in motion, or a body at rest tends to stay at rest unless acted upon by an outside force.

Learners follow the template to build and fly a paper helicopter.
