Science Fair Project Idea

Scientific Method

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

The Brains Behind 'Where's Waldo?'

Science Fair Project Idea

Scientific Method

What makes you notice someone in a crowd? Why do some things stand out, while others melt into the background? In this science project you can investigate the psychology of how things get noticed, by studying how our brains perform a visual search. Have you ever looked and looked desperately for something? It is so frustrating! The classic example is when I lose my keys. You would think that by now (knowing that I am the kind of person who often loses my keys) I would have a huge, bright red… Read more

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more

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

Now You See It, Now You Don't: A Chromatic Adaptation Project

Science Fair Project Idea

Scientific Method

This project shows that our perceptions can change, even with the stimulus remains the same. A clear color difference in an image disappears after just 20 seconds of looking at another (special) image. Now you see it, now you don't! 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

The Wagon Wheel Effect

Science Fair Project Idea

Scientific Method

Have you ever seen a video where it looked like a car's wheels were spinning backward even though the car was driving forward? What about helicopter blades that looked like they were spinning very slowly, or even not moving at all? This illusion is called the "wagon wheel effect," named after old movies where it looked like wagon wheels were spinning backward. In this science project you will learn how the wagon wheel effect works and how you can film it yourself. Read more

Guitar Jingle: Discovering the Locations of Harmonics

Science Fair Project Idea

Scientific Method

Did you know that your guitar has a secret? Yes, that's right—hidden along each string are special places where you can play harmonics and make your guitar sound like a bell! In this music science fair project, you'll find out where the main harmonics are located on a guitar, and then see how those locations are related to the length of the strings. So get out your guitar—it's time to ring in a science fair project! Read more

Learning Your A, G, C's (and T, too)

Science Fair Project Idea

Scientific Method

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this new alphabet. Read more

Throwing You Some Curves: Is Red or Blue Longer?

Science Fair Project Idea

Scientific Method

This a straightforward, but interesting, project in geometry. It is a good first proof to try on your own. You should be able to figure it out by yourself, and you'll gain insight into a basic property of circles. Figure 1 below shows a semicircle (AE, in red) with a series of smaller semicircles (AB, BC, CD, DE, in blue) constructed inside it. As you can see, the sum of the diameters of the four smaller semicircles is equal to the diameter of the large semicircle. The area of the larger… Read more
