During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

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

Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

In this activity, learners play a traditional Mexican game of chance with a twist. Learners take turns spinning a special "Toma Todo" top.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this math activity, learners build Peppy the dog the best trail and park for running around.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

In this Cyberchase activity, learners make decoders to send and receive secret messages. Learners make the device out of two 8-ounce cups and two code strips.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

With a straw, two craft sticks, and some rubber bands, construct a noisemaker called a Sound Sandwich and explore how vibration produces sound.

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.
