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

Earth is a planet full of water. 70% of its surface is covered with water in oceans, lakes, rivers, and more. Water on our planet can also be found in the atmosphere and underground. In this lesson, students will explore how water is continually cycled among land, the oceans, and the atmosphere. As students build a physical model of the water cycle, they will be able to simulate and observe evaporation, condensation, precipitation, and other water cycle processes in real-time. Remote… Read more

NGSS Performance Expectations:

MS-ESS2-4. Develop a model to describe the cycling of water through Earth's systems driven by energy from the sun and the force of gravity.

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

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

Chemical Analysis of Rainwater

Science Fair Project Idea

Scientific Method

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize the scientific area that most interests you. Read more

Have you ever imagined yourself falling asleep on a cloud? Did you know that if you were to sleep in a cloud, you would wake up soaking wet!? There are many different types of clouds, but one thing they have in common is that they’re all made of water (or ice). But how do clouds form, and how is it possible that water can float above us in the air? In this experiment you’ll make your own cloud in a jar, and get to test the conditions that are required to make a cloud… 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

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

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

Recycling Greywater: Can Plants Tolerate It?

Science Fair Project Idea

Scientific Method

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
