Isn't the human body incredible? From the complex systems that make it work to the numerous ways we're able to cure illnesses, there are so many fascinating subjects to study when it comes to human biology and health. Are you interested in subjects like how the body works, how best to keep it working, and how to cure everything from a common cough to cancer?

Science Fair Project Idea
You might have heard the saying "The eyes eat before the mouth." The appearance of food, especially its color, certainly affects how we perceive its taste. But can your eyes actually change the way you taste something? In this science project, you will find out by investigating how people perceive the taste of different colored apple juice. How do you think color affects taste? Read more

Remembering to take medicine at the right time can be hard, especially if you need to take multiple medications at different times of day. It might not be a big deal if you forget to take your daily multivitamin, but for some people, forgetting to take medication at the right time can be dangerous. What if you had a device that could not only set off an alarm at the right time, but also automatically dispense the right pills for you? In this project, you will build an automatic medicine… Read more
Science Fair Project Idea
Imagine if you had to take medicine every time you ate, and you had to use a math formula to figure out how much medicine to take based on the nutritional makeup of the food, how you were feeling, and what activities you were planning to do. You might also need extra medicine throughout the day (even in the middle of the night) based on your blood glucose levels. People with diabetes who take insulin do this every day. They use finger sticks and blood glucose meters or a continuous glucose… Read more

People have a variety of reasons to use heart rate monitors. For example, patients in a hospital might have stationary, bedside equipment monitor their heart rate and alert medical staff in case of an emergency. Somebody going for a run might wear a portable heart rate monitor to keep track of their workout intensity. Heart rate monitors are not all the same—their appearance and function will vary depending on the intended use. In this project you will design, build, and program your own… Read more
Science Fair Project Idea
Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars—glucose and sucrose—in different foods, and investigate how sucrose is converted into glucose with the help… Read more
Science Fair Project Idea
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! Read more
Science Fair Project Idea
Did you know that some teachers give their students a peppermint candy on state testing days? Is it to give the kids sweet-smelling breath? Or are the teachers hoping for something more on the important testing day? In this human biology science fair project, you'll explore whether or not peppermint influences scores on different types of tests. Read more

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… Read more
Science Fair Project Idea
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
Science Fair Project Idea
Alzheimer's disease and dementia affect millions of people around the globe. Can you design a "brain training" game that can help people keep their brains healthy as they age, and maybe one day help treat or even prevent diseases like Alzheimer's? Try this coding science project to find out! Read more
