This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and...

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out...

Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...

Here is a cool project about making fresh water from salt water using solar power, also known as water desalination. The apparatus is made from readily available materials, and the power source is free. As an inventive thinker, you will...

In this project, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine on heart rate. You do not have to learn how to take a crustacean's pulse though, because you can actually...

Watch out. It's Eddy Vortex, Superhero. He swirls, he tumbles, he churns up air and water. OK, maybe eddies and vortices aren't exactly superheroes, but they are powerful regions of air and water flow that you have to watch out for in...

The poet Carl Sandburg wrote, "The fog comes on little cat feet". In this weather science fair project, you'll discover why this beautiful, quiet creeper appears on some days, and not on others. If you are fascinated by fog and weather...

Find out whether reclaimed water is really safe by following the guidelines of the Science Buddies project.

You might know that lead can be toxic, and that you can get lead poisoning from eating or inhaling old paint dust. Lead is called a heavy metal, and there are other sources of heavy metals that can be toxic, too. Silver, copper, mercury,...

It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick-it can make electricity. Electricity can be generated...

Have you ever heard the expression "a canary in a coal mine"? In the 1900s and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous...

Provides a simple explanation of the water cycle by describing four main stages - evaporation, condensation, precipitation, and collection. Includes three project ideas and some interesting facts.
