Science Fair Project Idea
Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out. Read more

What is your favorite color and why? Do you think that simple tasks might be biased by your preferences? Find out in this science project if your color preferences will bias your fine motor skills when doing quick, repetitive tasks. Read more

Have you ever taken notes from the chalkboard during class and not noticed what was going on around you? Or have you ever been so focused on a task that you haven't seen other people around you? In both of these cases, you were paying attention, but you were seeing without seeing! This is called inattentional blindness and it's the topic that you will investigate in this human behavior science fair project. If you are interested in how the human brains perceives information, then this might… Read more

Have you ever seen a baby in the park and wondered if it was a boy or a girl? Maybe once you found out the gender, you thought how sweet, mischievous, or cute the baby was. But wait…do you think that the words you used to describe the baby might be based on your own gender stereotypes? A gender stereotype is when you expect someone to act a certain way simply because he or she is a boy or a girl. In this human behavior science project, you will investigate whether young children use gender… Read more

Have you ever bought or tried something new, just because of the way it looked, or the nice box that it came in? On your birthday, which present do you pick to open first? The one that looks big and colorful and exciting or the one that is wrapped in old tissue paper? The way that something is packaged and wrapped often advertises what is inside. But can attractive, exciting packaging convince you to try something that might not be very exciting, but is, perhaps, something that is good for you?… Read more
Science Fair Project Idea
Have you ever thought to yourself, "I have got to have that new video game right now?" Or maybe there's a new shirt at the store that you just have to have. So you rush home, break into your bank, and gather all of your money, even though you have been saving to buy your mom a gift. But wait! Maybe if you do a few more chores and save for just a few more days, you can gather enough money to buy your mom a gift and buy what you want. This behavior is called delayed gratification and it's what… Read more

Do you like to read? Did you know that most people read without even thinking about it? Find out in this experiment how a simple reading/color test called the Stroop Effect can show you how your brain works. Read more
Science Fair Project Idea
We've all heard that "practice makes perfect," but what is the best way to practice? For example, does "mental practice" do any good? You'll need at least 9 volunteers for this project. Pick a well-defined sports activity, with a measurable outcome, such as shooting basketball free-throws (measure number of shots taken and number of shots made), or balancing on one foot on a slightly raised beam (measure how long you can do it; if it's too easy, try closing your eyes). Test all volunteers… Read more
Science Fair Project Idea
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
Science Fair Project Idea
If you stare at a waterfall, or look at passing scenery from the window of a moving train, you will have a strange sensation when you turn your gaze to something stationary. You can investigate these types of motion after-effects with simple equipment described by the Exploratorium. How long does it take to induce the effect? How long does the effect last? Can the after-effect be canceled by viewing motion in the opposite direction? (Staff, date unknown) Read more
