Science Fair Project Idea
thumbnail When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not.

Science Fair Project Idea
thumbnail Does your skin get dry? Or do you know someone with dry skin? Dry skin can be a real medical problem for some people. You may have seen many kinds of lotions, creams, and ointments advertised as restorative for dry skin, especially dry hands. But how well do they work? And which ingredients are most important in making them work? In this science project, you will create a model of human skin using JELL-O® and test how well skin moisturizing products with different ingredients keep the… 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

Science Fair Project Idea
Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more

thumbnail While watching an ice hockey game, have you ever wondered what differentiates a good player from a great player? For sure, the great player is athletically superior to the good player. But maybe it is a combination of athleticism and equipment. Maybe a great player knows which hockey stick is best for him or her. Hockey players can choose to play with hockey sticks with different flexibilities or "flex." In this science fair project, investigate how stick flex affects shot accuracy and speed.… 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

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

thumbnail Do you live in an area where the weather changes a lot from season to season throughout the year? Or do you live in a place where the weather stays pretty much the same all year long? How dynamic is the weather, and how does it compare to climate? In this experiment you can use the Internet to conduct your own investigation about how climate and weather in your local area change over time. Read more
