In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to 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, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

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

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.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

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

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

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.

In this activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

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

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
