- Less Details
Time Required Short (2-5 days)
Prerequisites None
Material Availability Must have access to a stove, refrigerator, and a freezer.
Cost Average ($50 - $100)
Safety Use caution when handling the hydrogen peroxide, boiling water, stove, and blender. Adult supervision may be required for using the stove.
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
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
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
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 Have you ever noticed that most yogurt containers say they contain "live cultures"? What does that mean? The label is suggesting that the yogurt has living bacteria in it! While some types of bacteria can make you sick, some are actually important to keep you healthy. But individual bacteria are so tiny that you cannot see one with the naked eye, so how can you tell if bacteria are really living in your yogurt? In this science fair project, you will investigate whether yogurt actually… Read more

- Less Details
Time Required Long (2-4 weeks)
Prerequisites None
Material Availability You will need to special order the agar plates. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety The bacteria in the yogurt is not harmful; however, it is possible for other bacteria to grow on the agar plates. For that reason, make sure to follow all the safety guidelines in the Experimental Procedure. Be sure to dispose properly any plates with bacteria when the experiment is over. Adult help is required to light a candle.
Science Fair Project Idea
thumbnail In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Safety Use caution when handling ethanol because it is very flammable. Adult supervision is recommended for using the stove and a food processor or blender.
Science Fair Project Idea
thumbnail Alka-Seltzer® tablets fizz furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. Can you make Alka-Seltzer fizz faster or slower by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more

Science Fair Project Idea
thumbnail Have you ever had a refreshing bath using a bath bomb? A bath bomb is several ingredients mixed and molded into a shape, which becomes fizzy when it touches the water. It can be quite a relaxing experience, especially if your bath bomb has a nice fragrance or includes some bath salts. The fizz is the result of a chemical reaction taking place between different ingredients within the bath bomb. In this science project, you will get to make your own homemade bath bombs and explore how changing… Read more
