Project Idea
thumbnail What do Nolan Ryan, Mark Wohlers, Armando Benitez, and Roger Clemens have in common? These men are all major league baseball pitchers who have pitched baseballs at 100 miles per hour or greater! What does it take to throw a baseball this fast? Does it come down to having the biggest muscles? Can a ball thrown this fast also be accurate? In this sports science fair project, you will learn about the biomechanics of pitching. Investigate how body position and physics interact to produce fast… Read more

Time Required Short (2-5 days)
Prerequisites You should do this sports science fair project in a location where you can tie a clothesline either between two trees or two poles. Since you will be throwing a baseball, make sure that the location is away from windows and other breakable structures.
Material Availability You must have access to a camcorder and baseball equipment. Make sure that the camcorder has a timer and the ability to display the recording in slow motion.
Cost Low ($20 - $50)
Safety Minor injury is possible. Adult supervision is recommended.
Project Idea
thumbnail Thinking about improving your sports performance? Want to help friends and family make the most of their physical fitness activities? One factor to consider is food! Whether you realize it or not, what you eat does change your body! It affects how you feel, and can even change how you perform in sports. This science fair project will help you explore the link between what goes in your mouth and what your legs and arms can do. Read more

Project Idea
thumbnail 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.

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.

Project Idea
thumbnail What do you consider creepy? Clowns? Zombies? Video game characters with jerky movement? In 1970, a roboticist by the name of Masahiro Mori suggested that people are "creeped out" by robots that are almost, but not exactly, humanlike. He called this phenomena the uncanny valley. But researchers are still exploring and defining the uncanny valley. In this science project, you can do your own exploration—just try not to creep your friends out too badly! Read more

thumbnail Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Read more

Time Required Average (6-10 days)
Prerequisites To do this science project, you must live in an area where you can receive at least one strong AM radio station. You can check for this with a car or portable radio.
Material Availability Specific circuit items are required. A Science Buddies kit is available for your convenience. See the Materials and Equipment list for details
Cost Average ($40 - $80)
Safety Never operate your crystal radio during a thunderstorm. When not in use, always disconnect your antenna from the radio circuit, and connect it directly to the ground rod. Be sure to wear safety goggles when installing the ground rod, especially if you are using a metal hammer. An adult's help might be necessary for some steps in the Procedure.

thumbnail Do you like to tell adults where to go and how to get there? Well, here's your chance to do it in the name of science! In this science fair project, you will see what happens to your car's fuel efficiency when it takes you downtown to see a movie, up a hill for a great view, or out for a cruise on a flat country road.

Project Idea
thumbnail Do you ever feel like you need to walk faster than your parents just to keep up with them? This is because of the difference in leg length between you and your parents. How much faster do you need to walk than your parents? Can you use a walking test to determine how tall a person is? Read more

Project Idea
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
