Science Fair Project Idea
thumbnail Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Can a human hair hygrometer also detect changes in hair structure caused by chemical lightening? This project shows you how to find out. Read more

Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Will a hygrometer help you to predict bad hair days(!) or can you use it to help predict the weather? Read more

Science Fair Project Idea
The iodine clock reaction is a favorite demonstration reaction in chemistry classes. Two clear liquids are mixed, resulting in another clear liquid. After a few seconds, the solution suddenly turns dark blue. The reaction is called a clock reaction because the amount of time that elapses before the solution turns blue depends on the concentrations of the starting chemicals. In this chemistry science fair project, you will explore factors that affect the rate of the iodine clock reaction. Read more

Science Fair Project Idea
thumbnail There are many different types of vinegar that you can buy to use around the kitchen for cooking and pickling. The chemical compound that gives vinegar its tart taste and pungent smell is acetic acid. Do different vinegars have different amounts of acetic acid? How much variation is there between the different types? Find out for yourself with this science project. Read more

Science Fair Project Idea
thumbnail Caves have been used for much more than just exploring throughout Earth's history. Caves have been used for shelter, for religious purposes, and for burial sites. They were even used for food storage, before refrigeration, because they are cool and have constant high humidity. But how are caves formed? What causes those fantastic formations in caves? How do cave formations change as you go deeper in the cave? Get ready for an adventure as you visit a local cave and learn more in this science… Read more

Prerequisites Access to a cave system
Material Availability This science fair project requires that you own or can borrow safety equipment, such as a hardhat and sturdy shoes, to wear in the cave.
Cost Average ($50 - $100)
Safety In this science fair project you will be visiting caves. Please exercise caution when working in caves because the ground can be slippery. Always stay on prescribed paths.

thumbnail Everybody knows that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? Here is a project that gives you a peek into the fascinating science of exercise physiology. Read more

Science Fair Project Idea
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

Science Fair Project Idea
Did you know that you can make a simple hygrometer (a device for measuring the relative humidity of the air) with hair? This type of hygrometer is easy to build (for instructions, see: ). Does the type of hair used in the hygrometer affect the accuracy of the results? Do some types of hair respond faster than others? Do some types of hair give a larger (or smaller) response? You could get hair samples from classmates, or a local beauty shop. Use hair samples of equal length to construct… Read more
