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

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

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

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 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.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

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?

Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

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.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
