In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

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

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 (p.23 of PDF), learners dye wool with fungi. Learners discover that natural chemicals in fungi can dye wool different colors.

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

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

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 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

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

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 activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

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 build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity (page 7 of pdf), learners research tide pool ecosystems, and then create brochures that "advertise" these environments.

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

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

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.
