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

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 explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

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

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

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

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

In this multi-part activity learners examine non-point water pollution.

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

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 construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

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.
