Smarter Farming with Aerial Photo Analysis

Science Fair Project Idea

Scientific Method

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.

Disappearing Act: How Fast Do Different Biodegradable & Compostable Materials Decompose?

Science Fair Project Idea

Scientific Method

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

Going Green as You Clean: Are 'Green' Detergents Less Toxic Than Conventional Detergents?

Science Fair Project Idea

Scientific Method

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. Read more

Macroinvertebrates as Indicators of Pollution

Science Fair Project Idea

Scientific Method

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. Read more

Heavy Metals and Aquatic Environments

Science Fair Project Idea

Scientific Method

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. Read more

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more

Using Urine in a Microbial Fuel Cell

Science Fair Project Idea

Scientific Method

Every day, we produce a lot of sewage (wastewater full of feces and urine). In fact, it adds up to 6.4 trillion liters of urine alone produced worldwide each year! The sewage is collected and then treated or disposed of. But what if, along the way, there were a way to make that sewage do something useful? Human urine is rich in nutrients, and some bacteria actually thrive on eating those nutrients. There are also devices called microbial fuel cells that can generate electrical power by using… Read more

Household Water Usage

Science Fair Project Idea

Scientific Method

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… Read more

Looking Downstream: Could Nanosilver in Consumer Products Affect Pond Life?

Science Fair Project Idea

Scientific Method

Do you know that many consumer products, such as sports clothes, cosmetics, and even food containers contain tiny silver particles? These so-called nanoparticles—usually 1–100 nanometers (a billionth of a meter) in size—are toxic to bacteria and fungi and therefore, are used to prevent them from growing on everyday items you use. But what happens if the silver nanoparticles get into the water; for example, when you wash off your makeup or clean your clothes? Do they affect… Read more

Invasive Species

Science Fair Project Idea

Scientific Method

Invasive species are organisms (either plant or animal) that have been introduced into a new, non-native area and spread rapidly in the new environment due to a lack of regulation by predators. Frequently, invasive species will out-compete native species for resources which can put native species at risk. This is an especially big problem for threatened habitat and endangered species, which are already at risk. Survey your area to document cases of invasive species invading a local… Read more
