In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.
