Measuring Your Taste Threshold

Science Fair Project Idea

Scientific Method

Have you ever been to a buffet and found yourself surrounded by a wide variety of taste sensations? People are generally able to discern five basic tastes: sweet, umami (also known as savory), salty, sour, and bitter. How sensitive is a person's tongue for these basic tastes? Is it easier to detect some flavors at low concentrations compared to others? In this human biology science project, you will find out by exploring your taste thresholds for sweetness, saltiness, and sourness. Get ready to… 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

Predicting Thyroid Cancer Recurrence with Machine Learning

Science Fair Project Idea

Engineering Design Process

For cancer patients, remission–a period when the signs and symptoms of cancer are reduced or disappear–brings immense relief, but there is often a chance of recurrence, or the cancer coming back. Have you ever wondered how doctors can predict if cancer might come back in some patients? Thyroid cancer, a type of cancer affecting the thyroid gland, has a recurrence rate of about 5-30%. Depending on many factors, some patients may have a higher chance of thyroid cancer recurrence than… 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

Can You Walk the Talk? Exploring Distractions and the Timed Up and Go Test

Science Fair Project Idea

Scientific Method

Test your multitasking skills with the Timed Up and Go (TUG) Test! In this challenge, you'll evaluate a person’s functional mobility when they're focused versus when they're distracted. Can your brain handle walking and talking at the same time? Let’s find out! Read more

Minding your Mummies: The Science of Mummification

Science Fair Project Idea

Scientific Method

Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog. 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

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

Wearable Limp Detection Device

Science Fair Project Idea

Engineering Design Process

Have you (or anyone you know) ever sprained an ankle or broken a leg? It might have taken some practice to walk again after recovering from an injury. Some people might even need to work with a physical therapist. In this project you will program a wearable device to recognize when someone is limping instead of walking normally. Read more

Can Herd Immunity Combat Viral Epidemics like COVID-19?

Science Fair Project Idea

Scientific Method

One strategy you may have heard suggested for dealing with the COVID-19 epidemic is to let nature take its course and let COVID-19 infect enough of the population for us to reach the herd immunity threshold. Does this make sense as a public health strategy? You can explore this question scientifically using SimPandemic, a free online tool for modeling infectious disease outbreaks. Before you begin, you will need to know a bit about herd immunity. Herd immunity, sometimes called community… Read more
