Science Fair Project Idea
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!"

Are you convinced that virtual reality (VR) will soon become mainstream and improve our lives in unpredicted ways? Or maybe you believe it is a big hype doomed to fade and disappear. In this science project, you will use one aspect of VR—the headset—and investigate if it could convey reality better than traditional pictures or 360° images. You will go out and measure how people perceive pictures and images you took. Will people embrace the VR headset and what it can do or prefer… Read more

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 for this project, ask your teacher or fair coordinator for details.

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!

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

Dried beans are a major ingredient in dishes served all over the world. In their dried form, they can be stored for years and then "brought back to life" by soaking them in water. In this cooking and food science fair project, you will measure just how much water is absorbed by beans when they rehydrate (soak up water). Can such a little bean really hold that much water?

Have you ever watched an inexperienced video game player pick up a controller and start playing a game? Often the player bumbles around trying to figure out which button makes the onscreen character jump, run, turn left, or perform other actions. Some games are different though, they have control schemes that are more real-world based. Examples include Nintendo® WiiTM Tennis where you swing the Wii remote like a tennis racket and Activision's Guitar Hero® where you can play with a… Read more

Over an average lifetime, the human heart beats more than 2.5 billion times, supplying blood to the entire body. When a person exercises, the heart has to work harder than usual. Have you ever wondered how quickly your heart beats when you exercise, or how long it takes to recover back to its normal rate after you are done exercising? Is the heart rate recovery time faster for people who get regular exercise compared to people who do not? Try out this science project to find out! Read more

Maple syrup is deliciously gooey and great on breakfast foods like pancakes and waffles. But it has another amazing property. It can be turned into maple candies with a range of textures, like sticky maple taffy or molded maple sugar candy. In this science fair project, you will investigate how the temperature that maple syrup is heated up to affects what type of maple syrup-based candies can be made. Read more

Have you ever eaten half an apple and saved the other half for later, only to find that, by time you were ready to eat it, the apple did not look as tasty anymore? It may have turned brown and shriveled, and, if left out long enough, it may have spoiled. Do you think you could have prevented the other half from spoiling, or made it spoil less, if you had stored it differently, such as in the refrigerator in a food wrapping? In this cooking and food science project, you will investigate which… Read more
