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?

Tracking SARS-CoV-2 Spread from Wastewater

Science Fair Project Idea

Scientific Method

Have you ever wanted to know where hot spots of infection are or see how viruses spread? Are you interested in seeing how this changes over time? Check out our new science project that uses data visualization tools and tested wastewater data to track the virus that causes COVID-19 over time. Read more

Do Antibiotics Change Your Gut Microbiome?

Science Fair Project Idea

Scientific Method

There are thousands of bacteria in your gut that help you digest your food, recover important nutrients, and maintain your health. What happens to those bacteria when you take antibiotics? In this science project you will find out by accessing and analyzing a real data set of the gut microbiome (bacteria and other microbes) from healthy adults before and after they are given antibiotics.

Make a Color Detector App to Help Colorblind People

Science Fair Project Idea

Engineering Design Process

Do you know anyone who is colorblind, or are you colorblind yourself? What if you could carry a device in your pocket that could identify colors for you? Many people already carry around the device they need to do this - a smartphone! Since phones have built-in cameras, you can make an app that uses the camera to identify colors. In this project you will use a program called MIT App Inventor that makes it easy for anyone, even with no programming experience, to design your own mobile app. 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

Blood Clotting to the Rescue: How to Stop Too Much Blood from Flowing

Science Fair Project Idea

Scientific Method

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… Read more

Effects of Exercise: Changes in Carbon Dioxide Output

Science Fair Project Idea

Scientific Method

You might know that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? In this project, you will get a peek into the fascinating science of exercise physiology and find out—with the help of a color changing reaction. Read more

Exploring the Impact of Social Media on Mental Health with Machine Learning

Science Fair Project Idea

Scientific Method

Do you ever wonder if you spend too much time online? How can the amount of time spent on social media influence someone's mental health? What other factors play a role? In this science project, you will investigate which variables correlate with better mental health scores using a machine learning algorithm called the Random Forest algorithm. Read more

When Your Sniffer Snoozes, You've Got Olfactory Fatigue

Science Fair Project Idea

Scientific Method

The holidays are a wonderful time, when lots of good foods and good smells come from the kitchen. But have you noticed that if you stay in the kitchen awhile, you no longer notice the delicious smells? Don't worry! Your nose is not broken, you are just experiencing olfactory fatigue—basically, that's when your nose takes a nap. But what is behind olfactory fatigue and what happens when you experience it? Does a person's sense of smell "get tired" in the same way for different smells? Put… Read more

Make a Medical Alert Fall Detector

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what someone would do if they fell, got hurt, and could not get up on their own? What if they were home alone and could not reach a phone to call for help? Or, what if they lost consciousness - is there any way to automatically detect that they fell and needed help? In this project, you will program your own fall detector, a device that can automatically detect when someone has fallen over, then sound an alarm or even send a message to someone else. Devices like these are… Read more

Using AI to Detect Proper Exercise Form

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how Artificial Intelligence (AI) can be used to improve human health and medicine? Computers can now identify human joints as key points to track our body movements. They can then use this information along with training data sets to show us if we perform exercises safely, to prevent us from getting injured. Create your own data set and test out if your algorithm can reliably detect good and bad exercise form. Read more
