In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

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 are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners analyze a fictionalized report of life on Mars, based on a real NASA satellite photo, and explore how to separate scientific fact from fiction.

In this activity, learners of all ages will roll a ball coated with paint to artistically visualize the motion of the object.

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

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

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

What's a more compelling problem to solve than being stranded on a deserted island?

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this activity, learners set up a night time insect observation station with a light and sheet.
