Which Filtration Material Leads to the Best Drinking Water?

Science Fair Project Idea

Scientific Method

Do you filter your tap water before drinking? Many commercials claim these filters make your drinking water cleaner and safer. But what, exactly, are these filters doing, and is the water really cleaner afterward? The cleaning power comes from their filtering material, called activated carbon. It exists in various forms: powder, granules, foams, and blocks. Do you think it matters what type of activated carbon is inside the filter? In this project, you will investigate whether larger or smaller… Read more

Remove Microplastics from Water with Bioremediation

Science Fair Project Idea

Scientific Method

Have you ever walked by an ocean, lake, or river and seen plastic trash? Have you ever wondered how microplastics might be impacting the creatures living in these places? In this science project, you will investigate how yeast can be used in bioremediation to remove microplastics from contaminated water. Read more

Removing Microplastics from Water with Ferrofluids

Science Fair Project Idea

Scientific Method

Have you ever walked next to your favorite ocean, lake, or creek and seen plastic waste everywhere? Have you ever thought about how much plastic breaks down into microplastics and pollutes waterways? Scientists are coming up with new ways to remove these microplastics from our waterways, and now you can test them out for yourself at home. Read more

Solar-Powered Water Desalination

Science Fair Project Idea

Scientific Method

How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water? Read more

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

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

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

Solar-Powered Salt Removal

Science Fair Project Idea

Scientific Method

Have you ever thought about being stranded on a desert island? How would you find water to drink? What would you need to survive? In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun. 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

The Cold Wash Challenge: Testing How Well Enzymes Work in Laundry Detergents

Science Fair Project Idea

Scientific Method

What do you think are some of the most common stains on clothes? If you thought of grass, grease, ketchup, blood, or toothpaste stains, you are correct. Everyday activities like eating, playing outside, or doing sports can result in a lot of dirty laundry. Luckily, we have laundry detergents that can get our clothes clean again! Some of these detergents contain enzymes that are intended to boost cleaning power. In this science project, you will investigate how effective biological and… Read more
