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

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 how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

Many people get water from a source deep underground, called groundwater.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

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

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

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

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

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

Water treatment on a large scale enables the supply of clean drinking water to communities.

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.
