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

The Chinese invented paper made from plants and cloth about 2,000 years ago. Learners follow a similar process to make paper from recycled paper.

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

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

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

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 (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs.

In this activity, learners make a flip book that shows the progression of two solar events on reversible sides of the flip book.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

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?

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

Learners write or draw with white crayon on white paper. They look and feel to detect their marks on the paper. Then, learners paint over their paper with watercolor paint.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

Educator Amy O'Donnell from the American Museum of Natural History guides learners to create a diorama of a coral reef.

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