Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

In this activity, "write" a secret message in genetic code as beads on a string.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

In this activity, learners build small animated toys that move.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this activity, learners follow simple directions to explore and create platonic solids.

In this activity, learners make a photographic image—without a camera!

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.
