Science Fair Project Idea
Playing sports can be a lot of fun, but some sports pose higher risks of concussions, or brain injuries resulting from collisions, especially in contact sports like football. Some coaches, teams, and players use new warning devices mounted on helmets that sound an alarm after the head receives a serious impact. This gives an advanced warning of concussion risk (possibly before any of the medical symptoms might appear), signaling that the player should stop playing and see a medical… Read more

Time Required Long (2-4 weeks)
Prerequisites None
Material Availability This project requires access to a team of volunteers who play a contact sport (for example football, lacrosse, soccer, or hockey). See the Materials tab for details.
Cost Average ($50 - $100)
Safety The purpose of this project is to measure accelerations experienced during typical play. Never intentionally hit another player in the head.

The information and data collected in this activity are for educational purposes only. For specific medical advice, diagnoses, and treatment, consult your doctor.

Because of these health and safety concerns, adult supervision is required for this project. Some science fairs may require prior approval from the [# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="Scientific Review Committee" #] for this project, ask your teacher or fair coordinator for details.

As your mom and dad always tell you, a healthy diet is important to good health. This project is designed to see what happens to mice when they are allowed to load up on sugary snacks. Do you think that they will gain excess weight? Do you think that the mice will regulate their own intake and maintain a 'healthy' diet? You can try this project and find out for yourself. Read more

Have you ever wondered how nutritionists know how many Calories a certain food contains? In this project you will learn a method for measuring how many Calories (how much chemical energy) is available in different types of food. You will build your own calorimeter to capture the energy released by burning a small food item, like a nut or a piece of popcorn. This project gives a new meaning to the phrase "burning calories!"

Have you ever played a video game that made you break a sweat? Or pant a little bit? The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Do you think these video games can be considered exercise? This science fair project will help you find out! 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

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 seen a "Hail Mary" football pass, where the quarterback tries to throw the ball as far as possible to reach the end zone and score a touchdown? Or a last second game tying soccer goal from midfield? How far the ball will go does not just depend on how hard a player throws or kicks it; it also depends on the angle at which the player launches the ball. In this sports science project, you will investigate how launch angle affects the distance that a ball travels by filming… Read more

It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more

Tilt-A-Whirls, Merry-Go-Rounds, Spinning Tea Cups...does just the thought of them make you dizzy? Why should something so fun make our heads spin so long even after the ride has stopped? Learn about spins, turns, and the mixed signals that fire in our brains when the sensation of dizziness takes over. Weak stomachs, beware. This project has tests that will make your head spin!

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
