In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this activity, learners construct a home-made journal with simple, everyday materials.

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

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

In this story time program, young learners listen to the Dr.

In this engineering activity, young learners investigate multi-level buildings.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

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.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
