In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners watch a figure "magically" float up through the air.

In this activity, learners will put together towers using building bricks, then take the tower apart and challenge themselves to use the same bricks used to build a bridge.

In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

This activity explores the concept of center of gravity by having learners build a Jitterbug--a motorized toy that seems to dance--using a recycled CD and a DC motor.

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

In this activity, learners explore the work of paleontologists.

In this activity, young learners will learn about moon phases using materials found at home. This activity is adapted using play dough and cups to avoid food allergens and waste.

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 measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

This activity shows learners (with adult supervision) how to make a Glitter Globe, a fabulous toy that shimmers when you shake it.

In this activity, learners make a stroboscope--a spinning disk with slits around the edge that you look through.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.

In this math activity, learners make their own bubble wands and determine if the size of the wand affects the number of bubbles it produces.

In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.
