Ecological Footprint Analysis

Science Fair Project Idea

Scientific Method

The sustainability of our planet's resources ultimately depends upon our actions as citizens. How much we drive, what we eat, whether we have pets, and whether we recycle are all individual actions that affect the sustainability of the Earth's resources. Learn how ecological footprinting works and figure out how big your footprint is. How big is your family's footprint? Your school? A local business? Can you propose ways to increase or decrease the size of your ecological footprint? Develop… Read more

Feeding Earthworms: Do Different Diets Affect Them and the Soil They Enrich?

Science Fair Project Idea

Scientific Method

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

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

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

Here Today, Gone Tomorrow: Saving Migratory Animals

Science Fair Project Idea

Scientific Method

Extinct might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a… Read more

Home Sweet Biome: How Do Plants Grow in Different Environments?

Science Fair Project Idea

Scientific Method

Have you ever looked around and noticed the plants and animals that grow in your neighborhood? Have you ever visited friends in another part of your city, state, or even another part of the country? Have you noticed whether the plants and animals where they live are similar to those growing near you? What would it be like to live where they do? Why do certain plants and animals grow in one area, but not in another? In this science fair project you will learn about biomes and how different… Read more

How Long Does Trash Last?

Science Fair Project Idea

Scientific Method

Even though many cities have recycling programs, a lot of trash still ends up in the dump. Find out which materials will break down and which materials won't. Will the results of this experiment change which products you often buy? 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

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

Maybe you have grown vegetables or flowers, but have you ever grown the flowerpot? Yes, you read that right! In this activity, you will use mushroom roots to grow a biodegradable material that can be molded into a product of your liking, like a flowerpot! Growing a set of bowls, a lampshade, or a pot is easier than you might think. Once you try it out, you just might feel inspired to replace some of your plastic objects with ecological counterparts that you created from mushroom roots! Read more
