Abstract

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 themselves. This is the foam that one sees after beating egg whites for a while. When a cook beats an egg white, he or she usually does so with a wire whisk and a bowl. But what kind of bowl should be used? Does the material of the bowl help or hinder beating the egg white? In this science fair project, investigate how bowls made from copper, stainless steel, glass, plastic, and wood affect how long it takes to whip egg whites. Is the foam that you get from the different bowls similar or quite different? After you finish beating the egg whites, check how long the foam stays foamy. How long is the foam stable? Can you develop a reason why certain materials affect egg whites? Whipping an egg white might seem like a trivial cooking task, but there is some serious science involved. After you are done experimenting, add some sugar to your whipped whites and bake some meringue cookies to reward yourself for all your hard work!

Materials Scientist and Engineer

What makes it possible to create high-technology objects like computers and sports gear? It's the materials inside those products. Materials scientists and engineers develop materials, like metals, ceramics, polymers, and composites, that other engineers need for their designs. Materials scientists and engineers think atomically (meaning they understand things at the nanoscale level), but they design microscopically (at the level of a microscope), and their materials are used macroscopically (at the level the eye can see). From heat shields in space, prosthetic limbs, semiconductors, and sunscreens to snowboards, race cars, hard drives, and baking dishes, materials scientists and engineers make the materials that make life better.

Food Scientist or Technologist

There is a fraction of the world's population that doesn't have enough to eat or doesn't have access to food that is nutritionally rich. Food scientists or technologists work to find new sources of food that have the right nutrition levels and that are safe for human consumption. In fact, our nation's food supply depends on food scientists and technologists that test and develop foods that meet and exceed government food safety standards. If you are interested in combining biology, chemistry, and the knowledge that you are helping people, then a career as a food scientist or technologist could be a great choice for you! Read more
