How Protective is Your Helmet?

Science Fair Project Idea

Scientific Method

Every time you hop on your bike or gear up for football or baseball practice, your helmet is your first line of defense. Whether you’re coasting downhill or tackling on the gridiron, impacts happen — and they can cause more than just bumps and bruises. Scientists tell us that forceful hits to the head can lead to concussions or even more serious brain injury over time. Correct helmet design, proper fit, and good cushioning all help reduce those risks. For example, bicycling is one… 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

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

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more

Test and Change the Air Quality of Your Environment

Science Fair Project Idea

Scientific Method

Do you ever wonder if the air inside is cleaner or dirtier than the air you breathe outside? In this science experiment, you will test it using an air quality monitor. Have you ever wondered how lighting a candle in your room impacts your air quality? Did you cook and not turn on the fan? How did it affect your breathing, and how did it impact the air quality? In this project, you can see how these environmental factors can improve or worsen the air you breathe every day. 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

Can Your Body Temperature Tell the Time of Day? Find Out with Human Circadian Cycles.

Science Fair Project Idea

Scientific Method

Have you ever had to adjust to a new time zone and noticed that it takes a while before you start to feel normal again? By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms. Human beings, like many other living things, have a number of internal processes that show a distinct circadian rhythm. The most obvious is our sleep cycle, with activity during the day, followed by sleep during the night. Circadian rhythms have also been demonstrated… Read more

Design a Game to Help Alzheimer's Patients

Science Fair Project Idea

Engineering Design Process

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

Have you ever wondered how strong hair is? When we talk about our hair we usually discuss color, length or texture. But what about hair strength? If you look at a strand of hair, it looks like a very thin string. In fact, it is on average only about 0.1 millimeters thick. It doesn't seem like such a thin string could withstand much force. How much weight do you think a single strand of hair can carry? In this activity you will put a hair to the test and find out. You might be surprised by your… Read more
