Science Fair Project Idea
thumbnail Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. Do you like chemical reactions that stink and ooze foamy bubbles? Do you think it sounds fun to make a super gross liver smoothie? Then this is the experiment for you! Read more

Science Fair Project Idea
A solution consists of a solute dissolved in a solvent. A solution is saturated when no additional solute will dissolve in it. Can a saturated solution of sodium chloride dissolve any Epsom salts? Can a saturated solution of Epsom salts dissolve any sodium chloride? How does solubility vary with temperature? How does solubility vary with the surface area of the solute? Design experiments to find out! (Gardner, 1999, 16-17, Stretton, 2004) 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
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

Safety Adult supervision is required. Use caution when working with the oxygen canister.
Science Fair Project Idea
In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project ). The source of the material can be a cell line, bacterial culture,… Read more

Safety If bacteria or cell lines are used as the source of material for purification, [# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="SRC approval" #] may be necessary. Adult supervision is recommended.
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

Material Availability Readily Available
Cost Very Low (under $20)
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
In this project you'll make a liquid that will contradict your expectations. Hold it loosely in your hand and it will drip off your fingers, but grab it tightly and it will feel solid. Slap a bowl of it with a spoon, and instead of splattering, it solidifies. Do background research on colloids, and be sure you can explain the following terms: colloid, Newtonian fluid, non-Newtonian fluid, thixotropic. (For instructions on how to make it see the link listed under Exploratorium, 1998, in the… Read more

Science Fair Project Idea
Many essential chemical reactions and natural biochemical processes occur in liquid solutions, so understanding the chemical properties of liquid solutions is fundamentally important. This project asks the basic question, how much of a substance can dissolve in water, for three different substances: ordinary table salt, Epsom salts, and sugar. Read more

Science Fair Project Idea
During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… Read more
