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

Comparing Different Types of Irrigation Systems

Science Fair Project Idea

Scientific Method

With heat waves impacting the world globally, many gardeners, farmers, and scientists are turning to passive irrigation systems that reduce fossil fuel emissions while keeping plants well-watered and alive in the sweltering heat. In this science experiment, you will compare and contrast the effectiveness of passive irrigation systems compared to traditional surface irrigation systems and their impact on overall plant growth.

Dissolved Oxygen in Water vs. Temperature

Science Fair Project Idea

Scientific Method

To survive, we need oxygen in the air we breathe. Oxygen is also essential for most aquatic organisms, but there is much less oxygen available in water than in air. How much oxygen can dissolve in water? Does the temperature of the water matter? Learn how to measure dissolved oxygen and then see how oxygen concentration changes with water temperature. Read more

Acid Rain and Aquatic Life

Science Fair Project Idea

Scientific Method

Chemicals from Earth's atmosphere are making their way down to the planet! Not in spaceships, but in rain. The acid rain can infiltrate ground water, lakes, and streams. How does acid rain affect aquatic ecosystems? Read more

Using Daphnia to Monitor Water Toxicity

Science Fair Project Idea

Scientific Method

One way to test for the presence of toxic compounds in a water sample is a bioassay. In a bioassay, a living organism serves as a detector for toxins—the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay to monitor water quality. Many variations of this experiment are possible. 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

How Does the Tilt of Earth's Axis Affect the Seasons?

Science Fair Project Idea

Scientific Method

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

Making Species Maps

Science Fair Project Idea

Scientific Method

How do conservation biologists know which places are important to protect? How do nature guides know which animals can be found in which places? In this experiment you can discover how maps can be used to show how different animals are distributed in a local environment. Read more

Test and Change the Air Quality of Your Environment

Science Fair Project Idea

Scientific Method

Do you ever wonder if the air inside is cleaner or dirtier than the air you breathe outside? In this science experiment, you will test it using an air quality monitor. Have you ever wondered how lighting a candle in your room impacts your air quality? Did you cook and not turn on the fan? How did it affect your breathing, and how did it impact the air quality? In this project, you can see how these environmental factors can improve or worsen the air you breathe every day. 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
