Science Fair Project Idea
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

The holidays are a wonderful time, when lots of good foods and good smells come from the kitchen. But have you noticed that if you stay in the kitchen awhile, you no longer notice the delicious smells? Don't worry! Your nose is not broken, you are just experiencing olfactory fatigue—basically, that's when your nose takes a nap. But what is behind olfactory fatigue and what happens when you experience it? Does a person's sense of smell "get tired" in the same way for different smells? Put your… 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

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

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
thumbnail You have probably heard about left-brain and right-brain differences in people. The left brain is supposed to be better at language, and organizing sequential actions, the right brain is supposed to be better at visualizing orientations in space, making and listening to music, and deciphering the emotions of others. Is there evidence for left/right brain specialization in other animals? This project examines tail-wagging in dogs. Does tail-wagging show any evidence of left/right brain… 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

thumbnail Cake, cookies, pie, ice cream, hot chocolate, lemonade…Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will be… Read more

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

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
