Nut clusters, chocolate-dipped candies, and chocolate-dipped strawberries are just some of the delicious goodies that have a thin, rich layer of chocolate wrapped around them. But how do pastry and candy chefs make these delectable treats? The first step is to melt and temper chocolate. Tempering is a process in which the cocoa butter in chocolate is hardened into a specific crystalline pattern. When the cocoa butter molecules are in this pattern, the chocolate is shiny and breaks with a sharp… Read more

Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more

Walk into a fitness club and what kind of music do you hear? Slow, sparkling, relaxing music? Or driving, "up-tempo" songs that are designed to encourage you to move? Fitness clubs and other businesses, like restaurants and grocery stores, use background music to set the mood and to determine how fast they want their customers to move. The tempo of the background music is a key component to the environment that businesses want to create. Tempo is an important number or word inscribed by a… Read more

Did you know that your body has a built-in cooler? And it might not be what you think! Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair project, you'll use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt. Read more

You have probably had X-rays taken at the dentist's or doctor's office, but do you know how the X-ray images are made? Images made using X-rays, also called radiographs, are considered to be relatively safe to take, even though they are made using a small amount of radiation, specifically electromagnetic radiation. Radiation is energy that travels through space as either waves or high speed particles. Watch this video to learn more about electromagnetic radiation and X-rays. [[ Video… Read more

How a biological system functions is a consequence of the 3-D structures of biological macromolecules like proteins and protein complexes. Proteins can be categorized into different protein families based upon sequence, structure, and function. Typically, proteins in the same family have similar biochemical functions. You can investigate the structure of a protein by using protein databases (Entrez Protein, SwissProt, PDB) and 3-D computational models. You can compare the structures of… Read more

Whipped egg whites are used in many sweet and savory recipes. They are used to add air into cake batters, meringues, and soufflés. Egg whites, also known as albumin are 15 percent protein dissolved into water. When egg whites are beaten or whipped, the protein chains unravel. This is called denaturation. The process of whipping egg whites adds air to the mixture, in addition to denaturing the proteins. The denatured proteins create bonds with each other and trap air bubbles within… Read more
