Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help…
Have you ever been to the Grand Canyon and seen what water can do over millions of years? When you turn on the faucet, do you see water come out, or mud? In this experiment you'll find out how engineers help prevent erosion, which keeps dirt out of our water.
Soil may look like a bunch of dirt, but good quality soil is actually a complex mixture of dirt, nutrients, microorganisms, insects and worms. What type of benefit do these microorganisms offer a growing plant? You can test this by baking soil in the oven to sterilize and kill the microorganisms. Do plants grown in sterile soil do better than plants in unsterilized soil? What about adding worms to one plant, but not to the other. Will the plant with worms grow better? Some insects are bad…

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize the scientific area that most interests you.
Everybody knows that worms are good for the soil, but not everybody knows why. Here's a project that investigates just one of the ways earthworms improve the earth. Would earthworm castings (or earthworm manure) help your plants prosper and flourish? If so, how much should you use?
When you think of environmental challenges facing the world, the first things that come to mind might be global warming, or loss of biodiversity, since these are often in the newspapers. A serious problem that you may not have heard about is soil erosion. Why is soil so important? What is the danger of erosion? How can we measure soil erosion? What can be done to prevent it? Check out this project and you can start finding answers.
What looks pretty, stops flooding, and helps fight pollution? A rain garden! Find out how by building and testing your own miniature rain garden in a plastic bottle.
Interested in helping the environment, and don't mind getting dirty? In this project you get to mix it up with earthworms, soil, and various types of organic kitchen scraps. The basic idea is to set up small earthworm colonies to compost different types of food waste. You test the soils in each type to see how diet affects both the earthworm population and the nutrients they put back into the soil. This project takes a little time, but it's worth it. You'll help the environment and learn…
Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape.
A day at the beach is a wonderful way to spend time with your family and friends. You can swim, play games, and build sand castles. But have you ever thought about how all of that sand got there and wondered why the shoreline weaves in and out of the ocean? In this science project, you will investigate how ocean waves build beaches by making a model of the beach and shoreline. All you need is a tiny surfer and a beach volleyball court for your model, and you can imagine that you are in…
