No one likes shots, so why don't we swallow all our medications? In this science project, you will use a model to explore one challenge behind making medications we can quickly swallow, using insulin (a medication taken by some diabetes patients) as an example. Will your medication be functional after spending time in an environment similar to the stomach?

Yogi Berra said "You can observe a lot by just watching." In this human biology science fair project, you will observe how your eyes perceive color by watching afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. You will also learn how different cone cells in your retina respond to different colors.

Have you ever had a cut or a bloody nose that seemed like it would bleed forever? Though it might have seemed like a long time, it probably did stop pretty quickly. This is because different factors in a person's blood normally work together to plug the opening caused by the cut in a process called blood clotting or coagulation. However, some people have a genetic disorder called hemophilia that causes them to bleed excessively. If a person has hemophilia, he or she is usually missing some of…

The human body is an impressive piece of machinery, and your hands are no exception. With some training, they can perform delicate and complex tasks like manipulating pens and tools to create art. At the same time, hands have the strength and durability to hold a person's own body weight up on steep rocks. Unfortunately, there is a rapidly growing demand for hand replacements. But fortunately, scientists have studied human anatomy and biology and created human-like hands used as artificial…

Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond flour—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based…

Average ($40 - $80) |
| Safety |
The chemicals in the test kit could cause irritation if not handled properly. Be sure to wear gloves, safety goggles, and work in a well-ventilated area. Adult supervision is recommended. The small amount of sulfites contained in the iron indicator tablets may cause an allergic reaction in people who have asthma. |

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…

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. |

People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage,
but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping
your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina
to do all of the things that we want to accomplish, such as do our best in school and perform well in sports.
But what makes a cardiovascular system unhealthy, and what are the…

Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit saltier than you do? Try this science fair project if you want to find out more about the incredible, edible rock known as salt, and why people vary in how much of it they like to eat.

Have you ever watched a great sports player and imitated his or her moves over and over again? Or have you ever felt really bad when someone got hurt or things just weren't going his or her way? If so, you might be surprised to learn that you have been practicing skills closely tied to lying! In this science fair project, you'll discover how your brain gets a workout when it moves from truth-telling to lying, and how you can detect the shift. That's no lie!

What would you do if you saw one of your friends lying on the floor, not breathing, possibly having a heart attack? Call 911? Start CPR (cardiopulmonary resuscitation)? Those would both be important things to do! But do you know CPR? Do your friends and family know CPR? Chances are, most of them don't. Even if they do know CPR, they might be hesitant to use their mouths to perform it. You can change that though. In this science project, you'll create a simple, interactive game that can teach…
