Science Fair Project Idea
Do you know that many consumer products, such as sports clothes, cosmetics, and even food containers contain tiny silver particles? These so-called nanoparticles—usually 1–100 nanometers (a billionth of a meter) in size—are toxic to bacteria and fungi and therefore, are used to prevent them from growing on everyday items you use. But what happens if the silver nanoparticles get into the water; for example, when you wash off your makeup or clean your clothes? Do they… Read more

How do you like your mashed potatoes? Thin and whipped smooth? Or thick and mashed into chunks? Your mouth checks out not just the taste of your food, but its viscosity, or how it flows on your tongue, every time you take a bite! In this science fair project, you'll learn what viscosity is, and how to measure it in common liquids around your home. Read more

Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

Science Fair Project Idea
Plants need nitrogen to grow healthy stems and leaves. Although nitrogen is the most abundant element in the air we breathe, that form of nitrogen cannot be used by plants. Nitrogen contained in fertilizer, on the other hand, is readily taken up by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more

Science Fair Project Idea
Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond meal—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based… Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability This science project requires an iron test kit, available from [# Link Name="Chem_p090.7" Value="HtmlAnchor" #]. The Time Required estimate includes time for obtaining materials. Actual experimental time is only a few hours.
Cost Average ($40 - $80)
Safety The chemicals in the test kit could cause irritation if not handled properly. Be sure to wear gloves, safety goggles, and work in a well-ventilated area. Adult supervision is recommended. The small amount of sulfites contained in the iron indicator tablets may cause an allergic reaction in people who have asthma.

Here's a riddle for you: What would a latté be without a froth of bubbly milk on top? Answer: Black coffee! And how about a pumpkin pie without the whipped cream? Answer: Sad. Delicious, edible foams are everywhere, from sodas, meringues, and soufflés to mousses and whipped creams. They provide a delicious, spongy contrast to the foods they accompany, and their airiness releases aromas that enhance the eating experience. So, what makes a good foam? One with high volume and lots of… Read more

Science Fair Project Idea
Have you ever seen news coverage or other pictures of an oil spill in the ocean and wondered how all of that oil could be cleaned up? Oil spills can devastate wildlife by covering them with oil, and they can damage our precious water resources by contaminating them with oil. Part of the problem of dealing with oil spills is that the oil can be challenging to clean up. In this science project, you will test the absorptivity of different materials (called sorbents) to discover which ones are best… Read more

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

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
