In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

This activity offers learners and their families several ways to raise their awareness together about home water.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners create a biosphere in a baggie.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

In this laboratory activity, learners use a simple procedure to bait oomycetes from water and/ or soil and then examine these fungus-like organisms with the microscope to see how they look.

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

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

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 will explore vegetative propagation while preparing food scraps to grow into plants.

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
