Human Behavior Project Ideas

Project Idea
You've probably observed from your own personal experiences that some actions are contagious. Yawning is a great example. When one person in a room yawns, several other people usually do, too. Coughing, clearing your throat, these are other actions that often seem contagious. But what about smiling? Have you ever walked down the street and had a random stranger smile at you? Did it make you happy? Did you smile back? In this science fair project, you'll investigate whether smiling is… Read more

thumbnail 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

thumbnail Have you ever had to remember a long list of planets or the state capitals? These kinds of lists are full of interesting facts, but they can be hard to remember, especially for tests. What could you do to remember the list better? In this human behavior science fair project, you will learn about a memory technique called mnemonics (pronounced nuh-MAH-nicks) and investigate whether using mnemonics can help you and your friends remember lists of words.

thumbnail You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. 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

thumbnail 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
