As humans we are part of the environment. With over 7.5 billion of us on Earth, our combined actions also have a big impact on the environment. As long as we are aware of the impact, we can do things as individuals, and working together as groups, to lessen the detrimental impact of billions of people. Explore important topics like air quality, water quality, the effects of climate change, and many others to make informed decisions about caring for our planet.

Do you have any great-grandparents who lived through the Great Depression in the United States during the 1930's? If so, they might have stories to tell about terrible dust storms that blackened the skies, from the Midwest to the east coast. Severe drought was a factor in causing this "Dust Bowl" era, but decades of poor farming practices contributed to it, too. In this environmental science fair project, you'll learn about farming methods that help keep dirt from drying up into dust, and help… Read more

Many people are surprised to learn that the season's we experience—winter, spring, summer and fall—have nothing to do with the distance of Earth from the Sun. In this science fair project, you will investigate how the temperature on Earth actually depends on the tilt of Earth's axis of rotation. Read more

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… Read more

Have you ever heard the expression "a canary in a coal mine"? In the 1900's and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous gases, so if the birds stopped singing, or got sick, then the miners knew to leave immediately, even if they felt fine. As it turns out, our froggy friends are also very helpful at signaling problems, not in mines, but in and around bodies of water. Try this… Read more

Has the temperature in your house felt hotter or colder recently? This could be due to the greenhouse effect. The greenhouse effect states that gases in the atmosphere, such as CO2, might increase the surface temperature of Earth. In this science fair project, you will build a small model of Earth and use it to see how the temperature varies, compared to outside of the model. If you select this science fair project, you will be a part of the effort that is working to figure out what role… Read more
Science Fair Project Idea
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

Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more

Look out! When you walk on the grass, you are squishing millions of micro-invertebrates! Just kidding, these animals are too small to squish. Learn how to catch them by making a Berlese funnel in this fun project that will teach you about soil. Read more
Science Fair Project Idea
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

One way to conserve water is to find safe ways to use it more than once. Here is a project to test whether greywater (water that has been used for washing or bathing) can be used for watering ornamental plants. Read more
