Science Fair Project Idea

Engineering Design Process

Have you ever wished you could control your own suit of power armor like Iron Man? What about building a set of Wolverine-like retractable claws? You can get started by using electromyography (EMG) sensors, which can measure the tiny electrical signals generated by our muscles when they contract (Figure 1). You can interface these sensors with a microcontroller like an Arduino and use the output to control LEDs or motors. Getting these sensors to work can be tricky. The electrical signals… 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

Click a Button Without Your Hands: Design a Puff Switch

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how you could push a button without using your hands? How would you type on a computer or play a video game? You could use a puff switch - an electronic switch activated by blowing into a straw. This type of assistive device can help users with limited mobility or physical disabilities do everything from using a computer to steering a wheelchair. In this project, you will design, build, and test a puff switch that is connected to a tiny programmable board that you can use… Read more

Building Personal Medicine Apps to Help Patients

Science Fair Project Idea

Engineering Design Process

Remembering to take medication or perform a test regularly, consistently, and at specific times can be difficult for elderly people with short-term memory loss, or teenagers absorbed in activities. With mobile devices becoming our constant companions, could a smartphone or tablet offer a solution? The Massachusetts Institute of Technology (MIT) has created a simple tool making it possible for anyone who has a computer and Internet access to create a reminder app. It is easy, quick, and… Read more

How Fast Is Your Reaction Time?

Science Fair Project Idea

Scientific Method

Many sports skills require quick reaction times: think of hitting a 95-mph fastball, returning a 100-mph tennis serve, or blocking a slapshot at the net in hockey. (The Experimental Procedure section below has one way to measure reaction time.) Is your right hand faster than your left? Can you improve your reaction time with practice? Do both hands improve if you only practice with one hand? Try relating your reaction time to real situations in your favorite sport. For example, calculate… Read more

Blood Sugar Balancing Act: How Exercise Tips the Scales

Science Fair Project Idea

Scientific Method

You are probably very familiar with the fact that over time, exercise changes your muscles, your lungs, your bones, and even your mindset; but did you know it has an immediate effect on your body's biochemistry? You can see this in the amount of glucose (a type of sugar your body uses for fuel) circulating in your blood. Blood glucose levels change as you exercise. For most people, this is not a big deal. But for top-level athletes in the middle of intense exercise (like a marathon), or for… Read more

You Are What You Eat!

Science Fair Project Idea

Scientific Method

Thinking about improving your sports performance? Want to help friends and family make the most of their physical fitness activities? One factor to consider is food! Whether you realize it or not, what you eat does change your body! It affects how you feel, and can even change how you perform in sports. This science fair project will help you explore the link between what goes in your mouth and what your legs and arms can do. Read more

Use Machine Learning to Identify Lyme Disease-Transmitting Ticks

Science Fair Project Idea

Engineering Design Process

Ticks are a growing public health concern in North America, as their populations and the diseases they carry, like Lyme disease, are on the rise. But how can we help people identify the ticks they encounter to reduce their risk of infection? With artificial intelligence! In this project, you will gather image data of three different tick species and use a convolutional neural network (CNN) to classify them. You will also apply image augmentation techniques to expand and enhance the dataset,… Read more

Can Visualization Improve Your Sports Performance?

Science Fair Project Idea

Scientific Method

Did you know that athletes use visualization of sports tasks to score the winning shot in sporting games? Check out how much visualization impacts your precision in sports with this science project idea. Read more

Old Salty: Does Age Affect the Ability to Detect Salt?

Science Fair Project Idea

Scientific Method

Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit saltier than you do? Try this science fair project if you want to find out more about the incredible, edible rock known as salt, and why people vary in how much of it they like to eat. Read more
