Project Idea
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've 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's a project that gives you a peek into the fascinating science of exercise physiology. Read more

Time Required Average (6-10 days)
Prerequisites Interest in exercise physiology; the deeper your knowledge of acid-base reactions, the futher you can take this project
Material Availability Readily available
Cost Low ($20 - $50)
Safety Adult assistance recommended for construction and setup of respirometer and data collection
Project Idea
thumbnail This is a simple "kitchen chemistry" project about acid/base chemistry. Scientists measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. In this project you'll learn about the pH scale, and you'll make your own pH indicator paper using a pH-sensitive dye that you'll extract from red cabbage. You can use your pH paper to measure the acidity/alkalinity of various household solutions. Read more

Project Idea
thumbnail What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper? The answer, often overlooked, is: soil. With this project you can get all the dirt on soil formation, soil horizons, and the composition of different soils. Read more

Project Idea
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

Time Required Average (6-10 days)
Prerequisites Some chemistry knowledge will be helpful.
Material Availability Specialty items: You will need a lead test kit, which can be ordered online. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
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.
Project Idea
thumbnail One way to test for the presence of toxic compounds in a water sample is a bioassay. In a bioassay, a living organism serves as a detector for toxins—the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay to monitor water quality. Many variations of this experiment are possible. Read more

Project Idea
thumbnail You have probably heard the saying that "water and electricity don't mix." Well, in this chemistry science fair project you will mix them, to create two solutions, one basic and one acidic. The apparatus is very simple, but the chemistry is complex and offers many avenues for exploration. Read more

Safety Minor injury is possible. Be careful not to short out the battery, as it may get very hot.
Project Idea
thumbnail This project will teach you the basics of analytical chemistry, which is a must for students who want to go into chemistry or materials science. The molecules in objects we see all around us are constantly attracting each other. Different materials can be attracted or repelled depending upon their molecular structure. We can utilize the different attractive forces between substances to separate a mixture of compounds. Chromatography is a method to separate mixtures and identify each compound in… Read more

Safety Alcohol is flammable and toxic
Project Idea
The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to become more acidic. What impact does that have on the marine life? In this ocean science fair project, you will demonstrate ocean acidification and investigate the effect on the shells of marine life. Read more
