Science Fair Project Idea
This is a straightforward, fun project to measure the rate of the chemical reaction that occurs when Alka-Seltzer® tablets are plopped into water. You'll track the volume of carbon dioxide gas produced at regular intervals after the reaction begins. How does changing the temperature of the water affect the production of gas? 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
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.
Science Fair Project Idea
Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more

Science Fair Project Idea
Have you ever wondered how fun toys like Silly Putty, Gak, and Slime are made? These products are so much fun because of the properties of polymers, which make them delightfully bouncy, stretchy, sticky, moldable, breakable, hard, soft, and just plain fun! In this science project you can be the developer of your own putty product by changing the ratio of ingredients to change the physical properties of your putty polymer. By describing the physical properties of your results, you can choose… Read more

Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple… Read more

Imagine that you want to create your own brand of colored candies. You know they would be a success if only you could figure out how to make a certain color, such as purple. How can you do this when government regulators have approved just a few food dyes? First, you will need to find out how your competitors make all of their colors from these few dyes. Do different candy brands use the same or different dyes? This can be figured out with gel electrophoresis, a technique commonly used in… Read more
