Science Fair Project Idea
Earth, the Sun, wind, and water are all sources of renewable and sustainable energy—and sources you probably already know about. But did you know that you can get energy from such things as banana peels, coffee grounds, and newspaper? In a process called composting, you can transform kitchen and other solid wastes into a product that is beneficial for your garden: homemade fertilizer. As the waste decomposes, it also creates heat. Can this naturally created heat be put to use? In this… Read more

Prerequisites Making a compost pile can take anywhere from a couple of days to a few weeks, depending on the method and bin you use. In this energy and power science fair project, you will spend a few days creating a compost pile. You will have to account for the time as you are planning your science fair project. You will also need to be home for several hours at a time on many specific days throughout this project. Read through the Experimental Procedure for more details.
Material Availability You (and friends, if possible) will have to start collecting potato peelings or grass clippings a few weeks in advance to accumulate enough, so keep this in mind when budgeting time for your science fair project. See the Materials and Equipment list for details.

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… Read more

Do you know what plants need to grow? Sure, they need soil, water, and sunshine. Everyone knows that. But here's a secret: they also need nitrogen. Plants use nitrogen to make DNA in their cells and the proteins that lead to healthy stems and leaves. The problem is, although the Earth's atmosphere is made up of 78% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. So how do plants get their nitrogen? Either through nitrogen deposits in the soil, or through… Read more

Mowing the lawn is hard work, especially on a warm day. Not only do you have to mow the grass, but you also have to dispose of the clippings. Some people add the clippings to a compost pile in their yard, which is a great idea. But did you know that some grasses can be used as a source of energy? In this energy science fair project, you will learn more about a type of energy called biomass energy. You will grow different kinds of grasses and see which type of grass gives you the most biomass,… Read more

Have you ever bought or tried something new, just because of the way it looked, or the nice box that it came in? On your birthday, which present do you pick to open first? The one that looks big and colorful and exciting or the one that is wrapped in old tissue paper? The way that something is packaged and wrapped often advertises what is inside. But can attractive, exciting packaging convince you to try something that might not be very exciting, but is, perhaps, something that is good for you?… Read more
