Science Fair Project Idea
thumbnail 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

thumbnail Pennies are bright and shiny when they're new, but become quite dull with time. What causes such a drastic change? Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in water that is corrosive enough to strip off the copper oxide layer. It turns out, however, that the same process that makes the pennies shiny has bad consequences when it comes to copper pipes: it… Read more

thumbnail Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more

thumbnail Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

thumbnail Are oranges highest in vitamin C when they are fresh from the tree (or, in a pinch, the grocery shelf)? Does the amount of vitamin C in an orange change over time, after it has been picked? In this science project, you will find answers to these questions by measuring the amount of vitamin C in a solution using an iodine titration method. 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

When you burn a piece of wood, you start with wood and oxygen, and end up with ashes, carbon dioxide, and water vapor. At no time during the reaction does wood reappear, even momentarily, from the ashes. Most chemical reactions are like this; they move in one direction, from reactants (starting chemicals) to products. In this chemistry science project, you will experiment with a rare and exotic reaction that oscillates. The reaction products appear and disappear for a number of cycles. Because… Read more

Lead is a very hazardous element. Even very small amounts can cause health problems, especially in babies and young children. One way to determine if a household item, such as a toy or a piece of jewelry, contains lead is to soak the item in a solution, and then test the solution for lead that might have leached out of the item. The goal of this chemistry science fair project is to determine how varying the pH of the test solution affects its ability to dissolve lead, which is a critical step… Read more

Safety Adult supervision is required. The chemicals used in this science fair project are potentially hazardous. The test solutions contain lead and should not come into contact with skin or any part of your body. It also contains chemicals that produce a strong "rotten egg" smell, so the procedure should be carried out in a well-ventilated area.

You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more
