Leaky Clues to Dam Design: How Reservoir Height Affects Hydroelectric Power Production

Science Fair Project Idea

Scientific Method

It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick—it can make electricity! Electricity can be generated through the flow or through the fall of water. A big, fast-flowing river, for instance, contains a lot of moving energy that provides enough pressure to turn the blades of a turbine and run an electric generator. This same pressure can also be created though… Read more

How to Make the Boldest, Brightest Tie-Dye!

Science Fair Project Idea

Scientific Method

The clothes you wear are made of fibers that come from many different sources. Some fabrics are made from natural fibers, and some from manufactured or totally synthetic fibers. In this science fair project, you will explore how different fiber types react with dye. Are you dye-ing to find out which works best? Read more

Centripetal Force

Science Fair Project Idea

Scientific Method

What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat! It works because of something called centripetal force and it does much more than make a great roller coaster. It keeps a satellite in orbit and you in your bicycle seat during a turn. How does it work? Read more

Agrivoltaics: What Crops Grow Best Under Solar Panels?

Science Fair Project Idea

Scientific Method

We need farms for food, and we need solar panels for renewable energy. What if we could combine the two? Find out if certain crops can grow well under the partial shade of solar panels in this agrivoltaics science project. (Note: you do not need access to real solar panels to do this project. Any source of shade will work.) Read more

Pencil Resistors

Science Fair Project Idea

Scientific Method

What do you do with your old wooden pencils when they get too short to hold? Don't throw them away; you can use them to make circuits! This project will show you how to use pencils to make resistors, an important part of many electrical circuits, and test how they affect the brightness of a lightbulb in a simple circuit. Read more

Modifying a Car for Better Aerodynamics

Science Fair Project Idea

Scientific Method

Have you ever seen those cool wind tunnel pictures of cars with streams of smoke blowing over them? You do not need access to a wind tunnel to do a car aerodynamics science project! In this project you will use cheap, readily available materials—tape and yarn—to visualize airflow over a car. You will examine how you can affect the airflow over the car by making changes, like adding or removing accessories or making body modifications out of cardboard and duct tape. Maybe you can… Read more

Model Water Flow in Rivers

Science Fair Project Idea

Scientific Method

Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape. Read more

Balloon Morphing: How Gases Contract and Expand

Science Fair Project Idea

Scientific Method

Expanding gases are everywhere, from the kitchen to the cosmos. You've tasted their pleasures every time you've eaten a slice of bread, bitten into a cookie, or sipped a glass of soda. In this chemistry science fair project, you'll capture a gas in a stretchy container you're probably pretty familiar with—a balloon. This will allow you to observe the gas expansion and contraction as the temperature changes. Read more

From Sauce to Solid: The Science of Cranberry Condiments

Science Fair Project Idea

Scientific Method

"Slurp...plop!" Recognize that sound? You might if your family usually serves jellied cranberries for the holidays. Jellied cranberries are thick, like gelatin, and retain the shape of the mold in which it was placed, which might mean Aunt Sue's turkey mold or even the shape of the can if you buy one of the popular canned versions. Taking a bite of wiggly jellied cranberries can be a fun addition to a delicious meal, but cranberries can also be served as a sauce. Both versions use the same… Read more

Paper Bridge for Pennies

Science Fair Project Idea

Scientific Method

Using just a single sheet of paper (8.5 x 11 inches) and up to five paper clips, can you build a bridge that will span 20 cm and support the weight of 100 pennies? The area beneath the span must be free (so that boats can pass beneath it). To test your bridge, place two books 20 cm apart, and set the bridge on the books, spanning the gap. Do not fasten the bridge to the book (nor to any other support). Does your bridge hold as much weight as you expected it would? If your bridge fails… Read more
