Science Fair Project Idea
thumbnail Big, puffy, cotton-like clouds, and the bubbles in a pot of boiling water may not seem like they have much in common, but they do—both are formed by a heat-transfer process called convection. Warmed gases and liquids rise, while cooler ones fall, creating currents and mixing things up. Whether making processed foods in a factory or making plastic or metal parts, knowing how to mix up a big tank of hot and cold liquids or gases quickly is important. Engineers must rely on experimentation… Read more

thumbnail 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

thumbnail Of course it can, you say: ice is water and ice floats! And you're right. But we're talking about water in the liquid phase (the title reads better without getting overly specific). So how about it? Can liquid water float on water? Check out this project to find out. Read more

thumbnail A nice hot cup of tea sure can wake and warm you up in the morning. In this science fair project, you will investigate the chemistry of tea. The longer you steep a tea bag in hot water, the stronger the tea will be. But how does the strength of the tea change with longer brewing time? In this food science project, you will make a very simple electronic device to measure the strength of tea. The device will determine how strong the tea is by measuring the amount of light the tea absorbs. Read more

Science Fair Project Idea
thumbnail The enormous task of cleaning up oil spills in oceans and seas has burdened industry, government, and environmentalists for decades. The cleanup is almost always difficult. It involves great amounts of time, resources, and money to remove the oil from the water, and the cleanup is often only partially successful. Today, however, scientists are coming to the rescue, developing a new technique that combines nanotechnology and magnetism. In this science project, you will test the proposed… Read more

Safety Neodymium magnets are very strong. Some have the capacity to interfere or reset pacemakers. Never put a neodymium magnet in your mouth. Always keep them away from computers, credit cards, and other magnetized objects.

Ferrofluids create stains on skin and other materials, so take appropriate measures to keep the fluid contained to the working area.

thumbnail "Plastic made from milk" —that certainly sounds like something made-up. If you agree, you may be surprised to learn that in the early 20th century, milk was used to make many different plastic ornaments —including jewelry for Queen Mary of England! In this chemistry science project, you can figure out the best recipe to make your own milk plastic (usually called casein plastic) and use it to make beads, ornaments, or other items. Read more

Science Fair Project Idea
thumbnail What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

Science Fair Project Idea
thumbnail In this biology science fair project, you will observe how the Physarum polycephalum (P. polycephalum) organism responds to various amounts of glucose. P. polycephalum is easy to grow in a petri dish and responds in complex ways to its environment. Will it grow toward the chemical as it looks for a meal, or will it flee, trying to avoid further contact? Try this science fair project to learn more about chemotaxis in the fascinating Physarum polycephalum. Read more

Science Fair Project Idea
thumbnail 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
