In this activity, learners build a carousel toy that spins when pushed down.

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

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.

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.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

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

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

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

In this quick activity (page 1 of PDF under SciGirls Activity: Hockey), learners will use a simple physics of motion and gravity demonstration to test their predicting skills.

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

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

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Play with a slinky and make transverse waves. In this simple Exploratorium Science Snack, learners will experience making waves and will learn the different parts of a wave.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.
