In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.

In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.

In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

In this activity, learners use simple materials to create giant bubbles.

Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.
