This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex
