Wondering what sustainable, high-producing agriculture might look like? This science project explores how analyzing bird's-eye-view pictures of a field can make farmers aware of variations in their fields. Farmers can use this information to optimize their farming practices, or even feed this information to high-tech agricultural equipment so the machines can automatically adjust their actions (like fertilizing or watering) to the needs of a piece of land.

In this science project, you will collect macroinvertebrate samples from multiple points along a body of water, ideally a small creek or stream, and test the pollution burden and biodiversity of small organisms or insects to see if pollution impacts biodiversity.

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…

One way to test for the presence of toxic compounds in a water sample is a bioassay. In a bioassay, a living organism serves as a detector for toxins—the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay to monitor water quality. Many variations of this experiment are possible.

There is strong interest in "going green," including using products that cause less environmental damage when they are disposed of. In this environmental sciences project, you will compare the toxicity of "green" and conventional liquid detergents using worms as test organisms.

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, nickel, cadmium, arsenic, and chromium are all heavy metals that can be toxic in certain environments. In this experiment, find out if one common heavy metal, copper, can be toxic to an aquatic environment.

When you go to the beach, you may not know if the beach is natural or man-made. The popularity of sandy beaches prompted developers in the past to bring in sand to cover rocky shorelines and turn them into more popular sandy beaches. However, the actions of the tides, currents and waves carried the extra sand out into the reef, endangering the reef and the creatures living on it. You can use a water table to conduct experiments with sand movements and reefs. How is sand moved by water? How…

When is an animal considered endangered? When will it become extinct? What happens when a population has reached the limits of its resources? What happens to a population when a habitat changes? These are some of the questions population biologists try to answer. They use population models, created from math equations, to predict what will happen to a population over time. If you want to see how modeling is done and make some predictions of your own, you certainly won't need a crystal…

Visit your local landfill to collect dumping statistics by watching the types of trash people bring to the dump. Identify problem areas and types of waste that are commonly brought to the dump. Propose new uses for common landfill problems like tires, construction materials, plastics, appliances, and computer parts. Measure packaging materials of some common products. Invent ways to reduce the amount of packaging and increase the use of recyclable materials like popcorn or corn-based packing…

How much water do you use? Conserving water can do more than save your parents' money, it can also save freshwater ecosystems, wetlands, and watersheds. Some companies are trying to help fix the problem by making low flow faucets and showerheads. How well do they work? How much water can you save? Go to the hardware store to buy a few of the water saving products. Compare the amount of water that you run over a period of time to determine how much water you can save. Which water saving…
