Science Fair Project Idea
Have you ever known someone who had a bad reaction to a prescription drug? Although pharmaceutical companies test new drugs on a large number of people to make sure the drug works the way it is supposed to, often a small percentage of people respond differently to the drug. A person's genetics plays a large role in determining his or her response to a given drug. Our genes are made up of hundreds to millions of nucleotides of DNA (deoxyribonucleic acid), the genetic code. If… Read more

thumbnail It is fun to shake up a snow globe and watch the "snow" slowly fall. You can imagine that if the snow fell down very quickly it would be disappointing. But there are times when scientists in a laboratory want this to happen. Scientists use samples that have liquid mixed with small, solid pieces (like the inside of a snow globe), and they need all of the solid pieces in a clump, separated from the liquid. Instead of waiting for the pieces to slowly fall out of the liquid, scientists speed up… Read more

thumbnail Have you ever been in an earthquake? What did it feel like? Did you jiggle back and forth? Up and down? Was there a jolt? Or a rolling motion? Come build a house Hansel and Gretel would love to eat, a special table to shake it on, and see how different soil types can amplify shaking. Read more

thumbnail How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water? Read more

thumbnail Earth's atmosphere, the ocean of air that blankets the planet, is mostly nitrogen and oxygen, with small amounts of other gases. How much oxygen is present in air at sea level? In air high up in the Appalachians or Rockies? Atop Mount Everest? How much oxygen is present in the air you breathe? Here's a project that shows you how to measure the percentage of oxygen in an air sample. Read more

thumbnail The banjo's roots trace all the way over to Africa. The unique sound that a banjo makes depends, in part, on the resonator. The purpose of the resonator is to amplify and project the sound that is made by strumming and plucking the strings. In this music science fair project, you will experiment with a resonator on a banjo and see if you can hear the difference in sound. Read more

thumbnail Imagine that you could make an important piece of laboratory equipment in your kitchen. With this science project idea, you can! You will create your own centrifuge out of a salad spinner and some putty. In science labs, centrifuges are used to separate different liquids and/or solids from each other. You can load your homemade centrifuge with samples and see how they separate. What do you think happens to melted butter in a centrifuge? Read more

thumbnail Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… Read more

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.
