Science Fair Project Idea
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… Read more

Science Fair Project Idea
thumbnail You are probably very familiar with the fact that over time, exercise changes your muscles, your lungs, your bones, and even your mindset; but did you know it has an immediate effect on your body's biochemistry? You can see this in the amount of glucose (a type of sugar your body uses for fuel) circulating in your blood. Blood glucose levels change as you exercise. For most people, this is not a big deal. But for top-level athletes in the middle of intense exercise (like a marathon), or for… Read more

Time Required Long (2-4 weeks)
Prerequisites Informed consent must be obtained from participants in this experiment (parental consent must be granted for minors). The experimental design (including consent forms) must be approved by your fair's Scientific Review Committee ([# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="SRC" #]).
Material Availability A blood glucose monitoring system is required to do this science project. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety Follow all safety precautions when using the blood glucose monitoring kit and when handling blood, as described in the Procedure. If somebody who has diabetes wants to participate in this science project, review the safety notes at the beginning of the Procedure before starting.
Science Fair 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.

Science Fair Project Idea
thumbnail Are you in charge of feeding your family pet? How much food do you think your pet eats compared to other kinds of pets? After adjusting for your pet's body weight, you might be surprised how it will compare to other kinds of pets. What type of pet do you think will eat the most for its body weight? Read more

thumbnail 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

Science Fair Project Idea
thumbnail 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

Science Fair 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

Science Fair Project Idea
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

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
