Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

Learners construct a rocket from a balloon propelled along a guide string.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.
