In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.
