Science Fair Project Idea
If you're like most people, you like listening to music. Have you ever wondered how your ears and your brain turn the sound waves out there in the world into the experience of music in your head? If you're interested in doing a project about how we hear, this is a good one for you. With this project, you'll do background research and make measurements to understand how the sensitivity of your own hearing varies with the pitch of the sound. Read more

Science Fair Project Idea
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.

In this project you'll learn about how digital image files are encoded, and how digital images can be compressed so that the files take up less storage space and can be transmitted more quickly. You will also measure the quality of compressed and uncompressed images, which will give you important insights into the tradeoffs between file size and image quality. Read more

Science Fair Project Idea
Do you like to analyze stuff and finding out what it is made of? An analytical chemistry method, called chromatography, allows you to separate mixtures of compounds and to identify each individual compound within the mixture. Chromatography is used by many scientists, for example food scientists, forensic scientists, or organic scientists to analyze all kinds of mixtures such as food, blood, or medicine. In this project, you will be using paper chromatography to analyze the pigments from… Read more
