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
What Do We Do With Our E-waste?
Science Fair Project Idea
Scientific Method
If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more
What To Do About CO₂?

Where does CO₂ come from and how does excess carbon dioxide in the atmosphere affect the ocean and aquatic life? In this lesson students are introduced to the carbon cycle and explore pH and acidification with hands-on experiments. They then connect their experimental data with real-world data to evaluate claims about carbon dioxide and ocean acidification. Finally, students are introduced to how different companies and research groups are using green chemistry to build carbon capture… Read more
Wood vs. Alternative and Recycled Materials
Science Fair Project Idea
Scientific Method
Our forests are a very important natural resource that need to be managed wisely. We use wood products for many different purposes: building materials, paper, cardboard, furniture, fuel, etc. How can we use wood products in a sustainable manner? You can do experiments that examine the growth time of different tree species to see which are good candidates for tree farming. Which types of lumber are most sustainable? You can also compare the effects of clear cutting vs. thinning a forested… Read more
Biodiversity Survey
Science Fair Project Idea
Scientific Method
Survey your area to find out which species of plants and animals live there. You might be surprised to find out that something you grew up thinking was very common, is actually quite unique! For example, if you live in the great plains, then you may think that prairie dogs are a nuisance or a pest. Actually, some species of prairie dogs are only found here, and have a very important role for short and tall grass prairie ecosystems. The prairie dogs are an important part of the food-chain, and… Read more
Can Machine Learning Forecast Future Sea Levels?
Science Fair Project Idea
Scientific Method
Global sea levels are rising, but modeling and predicting them can be challenging with more and more extreme weather events. Can we use machine learning to track and predict sea level changes? In this science project, you will use previously collected data and machine learning to see if you can predict future relative sea level changes.  Read more
Deforestation
Science Fair Project Idea
Scientific Method
The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more

NGSS Performance Expectations:
  • MS-ESS3-4. Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.
Fish Markets and Sustainability
Science Fair Project Idea
Scientific Method
The sustainability of our ocean fisheries is a topic of concern for many, including environmentalists and fishermen who make their living on the bounty of the sea. It is important to use sustainable fishing practices so that our fisheries are not over-fished leading to a decline in productivity. Some states require fish markets to post information about their fish so that consumers can make informed decisions about which fish to buy. They post the type of fish (e.g., Coho Salmon), the source of… Read more
Household Water Usage
Science Fair Project Idea
Scientific Method
How much water do you use? Conserving water can do more than save your parents' money, it can also save freshwater ecosystems, wetlands, and watersheds. Some companies are trying to help fix the problem by making low flow faucets and showerheads. How well do they work? How much water can you save? Go to the hardware store to buy a few of the water saving products. Compare the amount of water that you run over a period of time to determine how much water you can save. Which water saving… Read more
