Program a Sound Level Meter to Help Protect Your Hearing

Science Fair Project Idea

Engineering Design Process

Have you ever said, "That hurt my ears!" when someone yelled loudly right next to you? Do you cover your ears when a fire truck drives by with the sirens blaring? It is good to protect your ears—even sounds that do not "hurt" can cause hearing damage if you are exposed to them for too long. In this project, you will program a device that alerts you when sounds have exceeded safe levels long enough to cause hearing damage. Read more

A Day in the Life of Your Heart

Science Fair Project Idea

Scientific Method

Did you know that your heart beats at different rates depending on what you're doing? The more physically active you are, the faster your heart beats. You can measure the rate your heart is beating by taking your pulse. This science fair project will show you how to take your pulse and help you investigate which daily activities get your heart beating the fastest. Read more

Modeling the Human Cardiovascular System: The Factors That Affect Blood Flow Rate

Science Fair Project Idea

Scientific Method

People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage, but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina to do all of the things that we want to accomplish, such as do our best in school and perform well in sports. But what makes a cardiovascular system unhealthy, and what are the… 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

Now You See It, Now You Don't! Test Your Peripheral Vision

Science Fair Project Idea

Scientific Method

Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test… Read more

The Power of Your Eyes: How Vision Affects Balance

Science Fair Project Idea

Scientific Method

Staying balanced might feel simple, but there’s so much more involved than you would think! The way your body balances is actually the result of several body systems working together. Your muscles and joints provide feedback (proprioception) about where your body is in space, your inner ear senses movement and position, and your eyes give you important visual cues about your surroundings. Vision is especially important because it helps your brain judge where you are in relation to the… 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

Do You Love the Taste of Food? Find Out if You Are a Supertaster!

Science Fair Project Idea

Scientific Method

Are you really picky about food? Or do you know someone who is? It might be because he or she is a supertaster! To supertasters, the flavors of foods are much stronger than to average tasters. Are you a supertaster? Find out with this tongue-based science fair project! Read more

How Shoe Tread Affects Traction

Science Fair Project Idea

Scientific Method

Have you ever noticed that some shoes grip the ground better than others? The pattern and design of a shoe’s tread can affect how slippery it is on different surfaces. You can test shoes with different tread patterns—like flat, ridged, or patterned—to see which design provides the best grip. By dragging a shoe along a surface with a spring scale at a constant velocity, you can measure how much force is needed for each shoe to slide on various surfaces. With this knowledge, you… Read more

Make an Adaptive Switch

Science Fair Project Idea

Engineering Design Process

How could you send a text message without using your thumbs? What about typing on a keyboard or using a video game controller without using your fingers? Due to a variety of medical conditions like cerebral palsy or paralysis from an accident, some people might be unable to easily use their hands and fingers to push small buttons or use joysticks. However, they might be able to use their entire hand to push a single larger button or use another part of their body like their foot or even their… Read more
