If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels. Read more

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

Have you ever wondered if some shapes have certain "sounds" to people, even if they have different native languages? For example, does everyone match certain physical characteristics, like sharpness or roundness, with certain sounds? Are there certain human sounds with meanings that can cross the language barrier? In this science project you will investigate this by testing the Bouba-Kiki Effect—will it turn out that abstract visual properties can be linked to sound? Read more

Did you know that the average child sees 20,000 30-second TV commercials in just one year? That's a lot of encouragement to buy new toys, clothes, entertainment, and food. In this behavioral science fair project, you'll find out some other ways (besides commercials) that marketers use to try and get adults to buy products, like having them touch or hold an item. You'll find out if these methods work with kids, too, and if they increase how much people are willing to pay for a product. It's a… Read more
