Science Fair Project Idea
You know there is sugar in non-diet soda, but just how much sugar? Sure, you can look on the ingredients label, but how do food scientists actually measure the amount of sugar in a solution? They use a simple scientific device called a hydrometer. The hydrometer floats in the solution that is being tested, and the higher it floats, the more sugar there is! In this science fair project, you will use a precision hydrometer to measure the amount of sugar in soda. Read more

thumbnail Ocean currents have profound effects on the climates of the continents, especially those regions bordering on the ocean. For example, the Gulf Stream (a warm current that goes around the North Atlantic Ocean) is thought to make northwest Europe much warmer than it would otherwise be. Similarly, the California Current is thought to keep Hawaii cooler than other land masses at the same latitude as it. In this ocean science fair project, you will model the behavior of these "rivers" of hot and… Read more

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 Have you ever dreamed of a world where you could take the scraps from last night's dinner and toss them into your car's fuel tank and make gas? Well, we're not quite in "Back to the Future" yet, but in this energy science fair project, you'll discover that food scraps, dead plants, sawdust, and other decaying organic matter, called biomass are a rich source of energy. You can get energy out of biomass by burning it, turning it into a liquid, or by turning it into a gas called biogas. You've… Read more

Time Required Long (2-4 weeks)
Prerequisites This science fair project requires access to a well-ventilated area, away from open flame or electrical sparks.
Material Availability A small quantity of fresh cow manure is required.
Cost Low ($20 - $50)
Safety This science fair project produces a small amount of a flammable gas, so it must be conducted in a well-ventilated area, away from any source of open flame or source of electrical sparks. Use caution and have an adult's help when using the bleach, as it can cause chemical burns.
Science Fair Project Idea
thumbnail Have you ever looked in the kitchen cupboard and found a container of tiny white grains, but you were not sure if they were sugar or salt? They look very similar. How could you tell them apart? Well, you know that sugar and salt taste very different. Taste is actually called a property, and properties are used to describe and identify different materials. Properties can also be used to physically separate things. In this science project, you will use different properties to create a way… Read more

Material Availability Iron filings and neodymium magnets may need to be specially ordered. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety An adult's help may be needed for using a knife and scissors to cut a plastic bottle. Follow all safety precautions when handling the neodymium magnets; these magnets should never slam together, never pinch fingers or skin, never be swallowed, and should be kept away from all electronic devices. Keep them out of reach of all young children and pets. An adult should help if a stovetop or oven is used.
