Popping an Ollie: How Skateboarders + Physics = A Really Cool Trick

Science Fair Project Idea

Scientific Method

Have you ever seen a skateboarder jump over an obstacle or slide down a railing? It looks like they are defying the laws of physics when they perform these tricks. It looks like it, but that's not the case. Physics describes the motion of objects and it is a skateboarder's best friend! All of these tricks can be explained by physics. In this sports science fair project, you will learn how speed affects "popping an ollie." The ollie is a basic skateboarding trick, and it's the first step to more… Read more

Experiment with Factors that Affect Roundup® Weed Killer

Science Fair Project Idea

Scientific Method

Farmers are constantly battling various types of weeds that compete with the crops they are trying to grow. One of the tools they use to combat unwanted plants is a chemical called glyphosate. Glyphosate is the active ingredient in Roundup, a widely used weed killer. In this plant biology science fair project, you will explore the factors that affect the activity of glyphosate. Read more

Can Copper Foil Snails?

Science Fair Project Idea

Scientific Method

If you have a garden, you probably know about snails (or their shell-less relatives, slugs). You may even be looking for a good way to keep them from getting into your garden and eating up the results of all your hard work. In this science project, you will take a scientific look at one method of discouraging this garden pest. Read more

Factors that Affect the Transfer of Force through Saturated Soil

Science Fair Project Idea

Scientific Method

Soil liquefaction is a phenomenon where soil that is saturated with water suddenly loses its strength and behaves like a liquid. This usually occurs due to sudden, large stresses on the soil — for example, from an earthquake. This can be very dangerous for buildings sitting on top of the soil, as they can suddenly sink into the ground! The embedded video explains soil liquefaction in more detail. Is there a way to prevent soil liquefaction? Do you think adding certain materials to… Read more

Bacterial Resistant Materials and the Best Disinfectant

Science Fair Project Idea

Scientific Method

If you'd rate yourself high on the bacteriophobia scale, just keep on scrolling down to the next project. Bacteria are all around us, and normally our body's defenses keep us blissfully unaware of them. If you don't mind finding out where they're lurking in your house, then you might find this project interesting. Read more

Fresh Whipped Cream That Lasts

Science Fair Project Idea

Scientific Method

Fresh whipped cream is the final touch for many delectable desserts. One issue with fresh whipped cream is that it has to be used soon after it is made, especially if it is at room temperature, or it starts to collapse into goo. This is a problem for its use in frostings or inside pastries as filler. Whipped cream can be stabilized by adding unflavored gelatin. Stabilized whipped cream can be used at room temperature and it has a much longer life. But how much gelatin is just right? Try… Read more

Killing 'Vampires': Saving Money and Power by Turning Off Computer Peripherals

Science Fair Project Idea

Scientific Method

What do you think about killing vampires? No, no, not the kind that drink people's blood, but the kind that suck your power and money away. Equipment like televisions, computers, printers, and fax machines all use electricity to operate, of course, but do you realize that this equipment might still be sucking electricity from the wall, even when you think it's turned off? These electricity-suckers are called vampire loads. In this science project, you will investigate how much power these… Read more

Beats

Science Fair Project Idea

Scientific Method

Beats are a pattern of oscillating sound intensity (i.e., the volume of the pattern grows and fades with a regular cycle). They occur when two tones of almost equal frequency interfere. People can perceive beat frequencies below about 7 Hz. Figure out how to create sound files to play pure tones on your computer. Create files with a pure tone of one frequency in the left channel, and a pure tone of a different frequency in the right channel. Systematically explore different frequency… Read more

Stand Up! Investigate the Effect of Different Bowls on Whipped Egg Whites

Science Fair Project Idea

Scientific Method

Whipped egg whites are used in many sweet and savory recipes. They are used to add air into cake batters, meringues, and soufflés. Egg whites, also known as albumin are 15 percent protein dissolved into water. When egg whites are beaten or whipped, the protein chains unravel. This is called denaturation. The process of whipping egg whites adds air to the mixture, in addition to denaturing the proteins. The denatured proteins create bonds with each other and trap air bubbles within… Read more

Zapping Yeast with X-rays

Science Fair Project Idea

Scientific Method

Have you ever wondered how X-rays affect living organisms? You have probably had X-rays taken at the dentist's or doctor's office. These X-rays are considered to be relatively safe, but every X-ray exposes a person to some radiation, specifically electromagnetic radiation. Radiation is energy that travels through space as either waves or high speed particles. Watch this video to learn more about electromagnetic radiation. When the energy in X-rays encounters an object, it can… Read more
