Science Fair Project Idea
What happens to the food leftovers in your home? Do they go in the trash? Down the garbage disposal? Or get gobbled up by the family dog? Food leftovers are a type of organic waste, a waste that comes from a plant or animal. Organic waste—like table scraps, agricultural waste, and human and animal waste—is biodegradable. This means, it can be chemically broken down by bacteria, fungi, or other living organisms into very small parts. [[ Image [] Figure 1. This photo shows… Read more

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? Read more

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

Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does a 'hot' compost pile compare to a 'cold' compost pile, or how does traditional composting compare to worm composting, or vermiculture? [[ Image [] Figure 1. Different composting methods yield different soils. In this picture, the soil on the left is… Read more

Worms are slimy, wiggly, and gross. But did you know that they have many unique abilities? One of the neatest things that worms can do is regenerate, or re-grow, parts of their body. After a piece of a worm is cut off, it can grow back with all of the necessary new parts. How much of a worm can you cut off and still get regeneration? Is one end of the worm better at regenerating than the other? See if you can make heads or tails of this wiggly problem! Read more

Science Fair Project Idea
Have you ever seen a product labeled "biodegradable" or "compostable" and wondered just how well it decomposes? A lot of different products claim to be biodegradable or compostable, such as food containers, bags, packaging materials, and spoons and forks. Not only do they clearly come in different shapes and sizes, but they are made of different materials as well. Do they decompose differently, and, if so, which decomposes the fastest? In this science project, you will make your own indoor… Read more

Science Fair Project Idea
Have you ever wondered why a plant that grows well in one environment may not survive in a different environment? For example, plants that grow well in a wet jungle would probably not do so well in a dry desert, lacking enough water. This is because plants have adapted to their specific environment. Some plants have even adapted to tolerate chemicals that would usually be toxic, such as various heavy metals. In this plant biology science project, you will investigate whether different… Read more

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.
Cost Very High (over $150)
Safety Wear safety goggles and use caution when working with all tools. Be sure to wear disposable gloves when handling animal waste and to clean all of the work surfaces thoroughly with a bleach solution.

Plants need nitrogen to grow healthy stems and leaves. Although nitrogen is the most abundant element in the air we breathe, that form of nitrogen cannot be used by plants. Nitrogen contained in fertilizer, on the other hand, is readily taken up by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more
