Science Fair Project Idea

Scientific Method

Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. 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

Measuring Soil Erosion

Science Fair Project Idea

Scientific Method

When you think of environmental challenges facing the world, the first things that come to mind might be global warming, or loss of biodiversity, since these are often in the newspapers. A serious problem that you may not have heard about is soil erosion. Why is soil so important? What is the danger of erosion? How can we measure soil erosion? What can be done to prevent it? Check out this project and you can start finding answers. Read more

Go and Stop? Ant Traffic Signals

Science Fair Project Idea

Scientific Method

Have you ever stopped to watch a trail of ants moving back and forth between a food source and their nest? Have you ever wondered how they establish their trail? You've probably read that ants use chemical signals to communicate with one another. This is a relatively simple experiment that you can do to determine whether ants use attractant signals (positive cues) or repellant signals (negative cues) or both. Read more

Making It Shipshape: Hull Design and Hydrodynamics

Science Fair Project Idea

Scientific Method

Sailboats, tugboats, barges, ocean liners, submarines are all different boats with different shapes. How does the shape of a boat's hull affect how easily it moves through the water? This project shows you how you can investigate this question using a homemade water trough and model boat hulls. Read more

How Secure Are Your Security Questions?

Science Fair Project Idea

Scientific Method

Many websites ask you to answer "security questions," like "What is your mother's maiden name?," to recover your account if you ever forget your password or login ID. However, sometimes the answers to those questions are easy to find online. Does this pose a risk to the security of important accounts like email and online banking? Are people even aware that this information about them is available online? In this project, you will investigate how secure people think security questions are, and… Read more

Which Cheesecake Baking Method is the Best?

Science Fair Project Idea

Scientific Method

Since ancient times, nothing has said "special" and "dessert" quite like cheesecake! The Romans even sacrificed their form of cheesecake, called libum, in religious ceremonies. Modern cheesecakes are more likely to be eaten at parties and at restaurants than used as sacrificial offerings, but no matter how they're enjoyed, all cheesecakes require some finesse in their baking and mixing to avoid common cheesecake faults, like cracking, collapsing, or failure to rise. In this cooking and food… Read more

Why Do Flying Rings Go So Much Further Than Frisbees?

Science Fair Project Idea

Scientific Method

If you've played catch with both Aerobie flying rings and Frisbees, you know that the rings fly much further than the Frisbees with the same throwing effort. Why is that? Investigate the aerodynamics of flying rings and flying disks and find out! Read more

Explore Perceptrons: A Simple Type of Neural Network

Science Fair Project Idea

Engineering Design Process

Have the phrases "machine learning" or "neural network" caught your interest, but you are not really sure how to use them in a science project? This project is a great place to start for beginners. You will learn about a very simple type of neural network—a computer program modeled after the human brain—called a perceptron. The perceptron can make a simple yes/no decision based on several inputs. You can "train" your perceptron to improve its decision-making abilities. Try it and… Read more

Will Different-colored Lights Affect How Many Moths You Catch?

Science Fair Project Idea

Scientific Method

You are coming into the house after a game of flashlight tag with your friends, but the front porch light is not on for you to see the doorknob! What is going on? Maybe your parents know that turning a light on means moths will gather there, and they do not want you letting moths inside when you open the door. You have probably noticed how moths are attracted to lights at night. They will even fly dangerously close to flames in their journey toward light. In this project, you will learn a… Read more
