In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

Coins are everyday objects which tell a lot about the people who use them.

Learn about dyes and mordants (fixatives) when you tie-dye fabric with Kool-Aid™ and vinegar. The colored molecules in Kool-Aid™ form a chemical bond between the fiber and dye molecules.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

Build time sense into the schedule by asking learners to predict what can happen in a certain amount of time: We have 20 minutes before outdoor time. What can you get done?

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.
