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.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

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

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

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

In this physics activity, learners build their own rockets out of film canisters and construction paper.

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 build simple catapults and use them to launch cotton balls.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

Learners construct and launch paper helicopters.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

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

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

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

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.
