Project Idea
thumbnail You have probably seen it on You Tube™ — the exploding Coke® and Mentos® experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller eruption? In this science project, you will see if using crushed Mentos candies, instead of whole Mentos candies, will affect the reaction. Read more

Project Idea
thumbnail What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more

Project Idea
Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more

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

Project Idea
thumbnail Do you enjoy eating smoothies packed full of berries and other tasty fruits? Or maybe you like drinking a creamy milkshake with peanut butter, chocolate, and bananas. Often, smoothies and milkshakes are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? Some ingredients in a smoothie can have more than one kind of sugar in them, and our bodies process each kind of sugar differently. In this science project, you will measure the concentration of… Read more

Project Idea
thumbnail The ingredients in Alka-Seltzer® tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces before dropping them in water? Find out for yourself with this project. Read more

Project Idea
thumbnail Do you want your hair to be shiny after you wash it? Do you want your clothes to stay bright and soft after laundering, and last a long time? You might think that a special shampoo or detergent can make this happen, but in this chemistry science fair project, you'll discover that how well people and things get clean has a lot more to do with the type of water used for washing than any special shampoo or soap. Did you know that water can be classified as either soft or hard? Soft water lathers… Read more

Project Idea
thumbnail While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself! Read more
