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.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

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

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

Millions of organisms can live in and around a body of water.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
