Science Fair Project Idea
thumbnail The Stroop effect describes an experiment about the time it takes to name the color of printed words. When you try to name the color in which color words are printed, it takes longer when the color word differs from the ink color than when the color word is the same as the ink color. This project is an interesting variation: what happens if you 'warp' the words into a curved shape that is harder to recognize as a word? Will the Stroop effect still happen? How 'warped' do the words have to be in… Read more

Can you pat your head with one hand while you rub your stomach with the other? This experiment is kind of like that, but it can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough, but see what happens when color words get in the way. Read more

thumbnail 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

thumbnail Everyone's used to the idea that people are either right-handed or left-handed for particular tasks. That is, one hand is preferred (or dominant) over the other for a particular task. Did you know that people also have a dominant eye? This project is designed to look for consequences of having the dominant hand and eye on the same side of the body (uncrossed) vs. having the dominant hand and eye on opposite sides of the body (crossed).

thumbnail Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or… Read more

Think it's a good idea to plug into iTunes, surf the Web, or watch TV while doing homework or trying to read? Lots of people do it and claim that jumping from one activity to another keeps their attention level up and even gives their brain some time to "relax" between the more challenging tasks. Just how efficient is multitasking? In this project, you'll find out after testing the ability of volunteers to successfully do two or more things at once. Read more

thumbnail Yogi Berra said "You can observe a lot by just watching." In this human biology science fair project, you will observe how your eyes perceive color by watching afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. You will also learn how different cone cells in your retina respond to different colors.

thumbnail 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

thumbnail Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test… Read more
