How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

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

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

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

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

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

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 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.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.
