Use this site as a resource to learn about the many aspects of water.

Learn about the importance of water quality and environmental influences that reduce it.

Iron is an important mineral essential for good health. Iron deficiency can be a problem. In this science fair project, use a simple iron test kit to measure the concentration of iron in water. This experiement is explained clearly and...

Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

Can water remain liquid below its normal freezing point? If it does, that water is supercool(-ed). This project shows you a method for supercooling water. You can test water from different sources to see whether or not it can be...

In this cooking and food science fair project, determine if you really need 6 quarts of water to cook a pound of pasta. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much.

Have you ever wondered what makes water 'bead' up on a freshly waxed car? In this project you'll investigate the chemistry of surface tension by measuring how many drops of water a penny can hold.

If you look carefully, you could find dozens of similar interesting phenomena that are all linked to the surface tension of water. Here is a project that will help you understand and measure the properties of water surface tension.

To survive, we need oxygen in the air we breathe. Oxygen is also essential for most aquatic organisms, but there is much less oxygen available in water than in air. Learn how to measure dissolved oxygen and then see how oxygen...

In this science fair project, use a calorimeter with an attached heating element to measure how water responds to added thermal energy.

In this lesson plan young scholars will learn about water treatment and what happens to water when it goes down a toilet and drains into sewers. Through further investigation students will understand the relationship between water...

Learning activities allow students to learn about tools for making science observations such as a magnifying lens and ruler. Then students describe how macroinvertebrates are adapted to their aquatic environment.

Great lesson plans covering a wide-range of science-related subjects. A wonderful resource for wonderful teachers!

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

We know that plants, and even bouquets of cut flowers need water to survive, but we often do not think about how water moves within a plant. In this science project, you will use colored water and carnations to discover how water travels...

The goal of this science fair project is to build batch solar collectors from different colors of plastic bags and see which collector is the most efficient in heating water.

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy experiment. Which objects will produce the most drag when pulled through the...

Amaze your friends and family by moving water with just a few turns of your wrist, this is known as an Archimedes screw. In this science project, you will build a very simple Archimedes screw, to transfer water from a low-lying location...

When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as...
