Science Fair Project Idea
Scientific Method
Are you good at tossing a Frisbee®? It is great when you throw a perfect, arcing curve, right on target! If you can do that, you have already trained your arm on the aerodynamics of Frisbee flight. Why not treat your brain to some Frisbee science with this project? Read more

Scientific Method
The insides of a car engine get very hot when the engine is running. Motor oil lubricates the moving parts, to keep the engine operating smoothly. What happens to motor oil as the engine temperature goes up? Read more

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

Scientific Method
The Wright brothers used kites extensively to test their design ideas in the years leading up to their first successful airplane flight. With this science project, you'll learn about kite aerodynamics, and then come up with your own hypothesis about building or flying a kite. You can test your hypothesis two ways: with an online kite simulation program from NASA, and outdoors with the real thing! A great feature of this science project is that it has many possible variations, so you can decide… Read more

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

Scientific Method
Mice, rats, and other rodents are typically nocturnal animals; that is, their activity level is highest at night. For this science fair project, you will build a device that records your pet's activity by monitoring movement of its exercise wheel to see how it varies during the day and night. You can also experiment with various ways of changing your pet's cycle of activity; for example, by playing with it during the day when it's normally resting. Read more

Scientific Method
Enjoy the thrill and pace of speed skating, do you? Well, this project's for you. Fast turns around the track become your laboratory tests in these experiments whether you skate on ice, wood, or pavement. The goal is to determine which type of turns are best in a race-tight, medium, or wide-and then to figure out why. You'll analyze the speed and stability of your turns and compare your results with those of a few fellow skaters. This is a friendly competition where the prize is learning… Read more

Scientific Method
This is a great science fair project for someone who is interested in both mathematics and art. Spidrons are geometric forms made from alternating sequences of equilateral and isosceles (30°, 30°, 120°) triangles. Spidrons were discovered and named by Daniel Erdély in the early 1970's, and have since been studied by mathematicians and artists alike. This project is a great way to learn about the mathematics and art of tiling patterns. Read more

Scientific Method
Have you ever heard that nanoparticles can kill bacteria? You may have even seen some consumer products advertise that they contain antibacterial nanoparticles. A nanometer is one billionth of a meter long. Nanoparticles are usually just a few nanometers in diameter — really, really tiny! So how can something that small kill bacteria which are approximately 700 - 1400 nanometers across? Are they really effective? In this science project you will grow some E. coli bacteria and… Read more

Scientific Method
Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within a short period of time. Hydropower energy is extracted from moving water, like ocean wave energy and tidal energy. In this energy science fair project, you will make a model of a tidal barrage (also known as a dam) and investigate how emptying the tidal barrage… Read more
