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

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

Students design and build their own parachutes in this hands-on engineering project.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

Coins are everyday objects which tell a lot about the people who use them.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners will explore how and why weight distribution works.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity learners will build a neighborhood out of blocks and cardboard.
