Science Fair Project Idea
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 woken up in the middle of the night just not feeling well? Maybe your mom or dad gave you some medicine and you felt better after taking it. Medicine is a great tool in the fight against an illness, but medicine can be a poison if too much is taken. Similarly, household products can clean your home and make it smell great, but if eaten, can be poisonous. That is why most medicines and household products are stored in childproof containers. But are childproof containers really… Read more

Are you convinced that virtual reality (VR) will soon become mainstream and improve our lives in unpredicted ways? Or maybe you believe it is a big hype doomed to fade and disappear. In this science project, you will use one aspect of VR—the headset—and investigate if it could convey reality better than traditional pictures or 360° images. You will go out and measure how people perceive pictures and images you took. Will people embrace the VR headset and what it can do or prefer… Read more

Do you ever use a password to log in to a computer, email account, or website? Do you use the same password for each one? Even if your password is very long or hard to guess, using the same password for many accounts can still be risky. If someone manages to find out your password (for example, via a phishing attack, or if you write your passwords down and someone finds the piece of paper), they could easily access many of your accounts. However, memorizing lots of different passwords can be… Read more

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

Oh, were you ever scared! Your heart pounded, your breath rate shot up, your palms got cold and clammy. Fear does that to us. Here's a science project based on roller coaster rides to see if heart rate is an accurate measurement of fear. Are you brave enough to take on this frightfully fun project? 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

Okay, now you've done it. You goofed off, didn't study for your math test, and didn't do well. Mom and Dad are not going to be happy. In fact, they might even be angry. They don't say anything when they see your test, but you can tell from their faces that they are angry. But how can you tell? How can you tell if someone is angry, or happy, or sad? The answer is that you have learned how to tell someone's emotional state from his or her facial expressions. Are facial expressions of happiness or… 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 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
