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

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.

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 three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners are divided into teams.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
