Science Fair Project Idea
thumbnail Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment. In this geology science project, you… Read more

Science Fair Project Idea
thumbnail What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper? The answer, often overlooked, is: soil. With this project you can get all the dirt on soil formation, soil horizons, and the composition of different soils. Read more

thumbnail Do you think worms are gross? Or that they are only good for birds or fish to eat? Well, in this zoology science project, you will find out that this lowly animal helps to put food on your table, too, by all the hard work that it does in the dirt. In this science project, you will discover in what kind of soil it likes to do its work. It is wiggly good fun! Read more

Science Fair Project Idea
thumbnail How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water? Read more

thumbnail 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 through the flow or through the fall of water. A big, fast-flowing river, for instance, contains a lot of moving energy that provides enough pressure to turn the blades of a turbine and run an electric generator. This same pressure can also be created though… Read more

Science Fair Project Idea
thumbnail Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. Read more

Science Fair Project Idea
thumbnail Have you ever thought about how fortunate you are to have safe and clean water coming out of your faucet? Many people in undeveloped nations don't have this luxury. But does that mean they can't have clean water at all? Is there an inexpensive way they could use to make their own clean water? In this microbiology science fair project, you will investigate whether or not sunlight can disinfect contaminated water. Read more

You should always exercise caution when obtaining a water sample from a creek or a stream.
Science Fair Project Idea
thumbnail Have you ever dreamed of a world where you could take the scraps from last night's dinner and toss them into your car's fuel tank and make gas? Well, we're not quite in "Back to the Future" yet, but in this energy science fair project, you'll discover that food scraps, dead plants, sawdust, and other decaying organic matter, called biomass are a rich source of energy. You can get energy out of biomass by burning it, turning it into a liquid, or by turning it into a gas called biogas. You've… Read more

Science Fair Project Idea
thumbnail 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… Read more
