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?

Make an Automatic Pill Dispenser
Science Fair Project Idea
Engineering Design Process
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
Make a Heart Rate Monitor
Science Fair Project Idea
Engineering Design Process
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
Dealing with Diabetes: The Road to Developing an Artificial Pancreas
Science Fair Project Idea
Engineering Design Process
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
Sucrose & Glucose & Fructose, Oh My! Uncovering Hidden Sugar in Your Food
Science Fair Project Idea
Scientific Method
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 of an… Read more
Can You Train People to Breathe Better?
Science Fair Project Idea
Scientific Method
The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more
Make an Automatic Braille Display to Help Blind People
Science Fair Project Idea
Engineering Design Process
We take it for granted that computer screens can update the text on their displays. What about braille, the writing system used by blind and visually impaired people? Braille writing usually consists of a series of permanently raised bumps on a surface like a piece of paper or a sign. How can you make these bumps change or "update" to display different text? Find out in this engineering project as you design and build your own refreshable braille display.  Read more

How well do you wash your hands? Do you just give them a quick rinse with water, or do you use soap? Do you wash the backs of your hands and in between your fingers? Good hand washing is one of the best ways to prevent the spread of germs and diseases like the flu and common cold. Try this activity to find out if there are hard-to-wash parts of your hands where germs might be hiding! Read more

Did you ever wonder what hand sanitizer is made of, or how you can efficiently disinfect your hands or other frequently touched surfaces like doorknobs? Handwashing is still the best way to keep your hands clean, but hand sanitizer is a great alternative for situations where clean water and soap are not available, and you can even use it to disinfect surfaces! Intrigued—try out making a hand sanitizer yourself! Read more

Have you ever wondered how visual illusions are made? When we see special effects in movies, or a magic show, we often witness illusions that challenge our ability to correctly perceive things. One way in which our eyes play tricks on us is through afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. In this science activity, you will look at afterimages to reveal the secrets of how your eyes see color. Read more
