Science Fair Project Idea
thumbnail Why are some fruits, like pineapple, not recommended for adding to gelatin? It is because the gelatin may not solidify well if it has these fruits in it. In this science project you will determine whether certain enzymes in some fruits are preventing gelatin from solidifying, and whether there is a way to still include these fruits without ruining your gelatin dessert. It is an experiment with edible results! Read more

Safety Adult supervision is recommended for making the gelatin, which involves using boiling water and a knife to cut the fruits.
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

Time Required Long (2-4 weeks)
Prerequisites A class in chemistry would be helpful, but is not required.
Material Availability You will need to order the Oscillating Chemical Reaction Kit online. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety Adult supervision is required. Minor injury is possible. Be sure to wear safety goggles.
Science Fair Project Idea
Yeast contains an enzyme, called catalase, that acts as a catalyst for the reaction that breaks down hydrogen peroxide into oxygen and water (2H2O22H2O + O2). Safety note: oxygen is a highly reactive gas, adult supervision recommended for this project. For your background research, be sure that you understand substrate, catalyst, reaction rate, catalase, enzyme saturation and protein denaturation. Use a solution of 3% H2O2 for the substrate. Construct an apparatus that allows you to collect… 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

Time Required Average (6-10 days)
Prerequisites You should be attending or already have taken an introductory chemistry class. This science fair project requires careful attention to detail and will involve some creative problem solving and independent research on your part.
Material Availability You will need to order a chemical kinetics kit online. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety Wear safety goggles when working with all chemicals. Hydrochloric acid is corrosive to hands and eyes. Wear splash goggles and gloves when handling acids.
Science Fair Project Idea
Many proteins act as catalysts which speed up or regulate a biochemical reaction. The kinetics of an enzyme can be investigated by measuring the reactants and products of the reaction over time. Research the enzymatic reaction of a protein and investigate its kinetics. Measure the production of hydrogen peroxide (H2O2) by catalase, the digestion of gelatin by papain, or any other enzymatic reaction you have access to. Bio-Rad's provides a great measurement platform for exploring… Read more

Science Fair Project Idea
Have you ever pulled a muscle or just been sore after a long day of work or exercise? Hot showers are great, but maybe you've used the more convenient heat packs. Heat packs, which you can buy at grocery or drug stores to soothe aching muscles, use exothermic reactions to produce a low level of heat that lasts for an extended period of time. Exothermic reactions change chemical energy into heat energy. In this chemistry science fair project, you will use heat packs to study the heat-generating… Read more

Science Fair Project Idea
thumbnail Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars, glucose and sucrose, in different foods and investigate how sucrose is converted into glucose with the help of an… Read more

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
