Science Fair Project Idea
thumbnail Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items that are blue in color have the same dye, called FD&C blue 1. In this chemistry science fair project, you will build a simple colorimeter, a device that measures the concentration of colored chemicals in solutions. You will use the colorimeter to measure the concentration of blue dye #1 in sports drinks, and to track the rate at which the… Read more

Science Fair Project Idea
Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors. Read more

Science Fair Project Idea
thumbnail You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more

thumbnail Many people you know probably have an opinion about the kind of milk they like to drink—some like it thin and refreshing, others like it thick and rich. Milk can be bought with different fat concentrations, but other than that, it's all the same. Or is it? This science fair project raises a few interesting questions about the other contents in milk. Do all milk products have the same protein concentrations? Do cows produce different types of milk during different stages of lactation?… Read more

Science Fair Project Idea
thumbnail Imagine that you want to create your own brand of colored candies. You know they would be a success if only you could figure out how to make a certain color, such as purple. How can you do this when government regulators have approved just a few food dyes? First, you will need to find out how your competitors make all of their colors from these few dyes. Do different candy brands use the same or different dyes? This can be figured out with gel electrophoresis, a technique commonly used in… Read more

Science Fair Project Idea
thumbnail You've probably noticed the colorful patterns "reflecting" from the shiny surface of a CD disk. What you are seeing is actually diffraction of white light, and the rainbows of color are diffraction patterns. In this project you'll learn about how diffraction patterns are generated, and you'll find out how you can use a laser pointer and a protractor to measure the microscopic spacing of data tracks on a CD.
