Harvesting Fresh Water With a Fog Catcher

Science Fair Project Idea

Scientific Method

Did you know that about 1 in 10 people worldwide do not have access to clean water? Collectively, girls and women worldwide spend an average of 200 million hours every day collecting the water they need from rivers, water holes, or lakes. What if there was a way to capture water from another source—like the air? In areas where there is a lot of fog, a device called a fog catcher makes this possible. Fog catchers use fine meshes to capture and collect water droplets from the foggy air.… Read more

Predicting Future Water Quality with Machine Learning

Science Fair Project Idea

Scientific Method

Understanding the water quality of our rivers, streams, and lakes is critical for maintaining healthy ecosystems and sources of drinking water. Dissolved oxygen is one key water quality measurement that impacts aquatic life. But how can we predict how water quality might change in the future so we can intervene to keep our water healthy? With machine learning! In this project, you will gather water quality data for a location of your choice and use a random forest model to predict future… Read more

Dust Busters: How No-Plow Farmers Try to Save Our Soil

Science Fair Project Idea

Scientific Method

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

Fight Flooding and Pollution with...a Garden?!

Science Fair Project Idea

Scientific Method

What looks pretty, stops flooding, and helps fight pollution? A rain garden! Find out how by building and testing your own miniature rain garden in a plastic bottle. Read more

Modeling Your Local Watershed and Nutrient Pollution

Science Fair Project Idea

Scientific Method

Have you ever been unable to swim in a body of water because it was polluted? Have you ever wondered where the water came from, or what contributed to its pollution? In this science project, you'll learn how water drains to common areas to create bodies of water and how the land surrounding a waterway can contribute to its health and pollution. Read more

Bug Vacuums: Sucking up Biodiversity

Science Fair Project Idea

Scientific Method

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

Predicting How Urban Wildfires Will Spread

Science Fair Project Idea

Scientific Method

Urban wildfires can cause devastating loss of life and property. Can we save lives by predicting how and where these fires will spread? What protective measures can we take to save buildings from the fires? In this project you will use a computer model to simulate how wildfires spread in populated areas, and experiment with different protective measures to try and save houses from burning. Read more

Cleaning up Dyes from Contaminated Waters using Yeast

Science Fair Project Idea

Scientific Method

Have you ever wondered how your clothes got the colors they have? What dyes were used to color them? And after the clothes were manufactured, what happened to any leftover dyes? It turns out that many waters around the world are contaminated by dyes, and this can impact animal and human health. In this science project, you will investigate how active, living yeast may be able to break down dyes in contaminated water. Read more

Investigate the Greenhouse Effect

Science Fair Project Idea

Scientific Method

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

How Does Soil Affect the pH of Water?

Science Fair Project Idea

Scientific Method

Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out. Read more
