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.

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

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 drop two different masses of play dough and observe how long it takes them to hit the ground.

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

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.

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

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 make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).
