In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners explore different ways to stack cups to meet a personal goal.

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.
