Science Fair Project Idea

Scientific Method

Bristlebots are tiny little robots with no "brain." They are powered by vibrations and move around randomly. Even if there is no brain, can you still influence how they move by changing their design? Find out in this fun robotics project! 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

The Taylor Swift Challenge

Science Fair Project Idea

Scientific Method

Taylor Swift famously got in shape for her three-hour-long Eras Tour concerts by singing all 40+ songs...while running on a treadmill! Have you ever tried running while singing at the top of your lungs? How hard do you think it is? In this science project you will measure the impact talking and singing have on a group of volunteer runners. Is anyone in better shape than Taylor Swift? Read more

Build Your Own Radon Detector

Science Fair Project Idea

Scientific Method

Electronic devices can be designed to detect dangerous fumes or other hazards, such as smoke or carbon monoxide. In this electronics project, you will build another potentially life-saving detector—a radon detector. Radon gas is radioactive and can pose a hazard to your health if you live in an area where it leaks from the ground. In this electronics science project, you will learn how to collect radon with an ordinary dusting cloth mounted on the intake of a fan, and then measure its… Read more

How to Control a DIY Mini Drone with an Arduino™

Science Fair Project Idea

Engineering Design Process

Most drones fly with a mix of human input and autonomous control based on feedback from electronic sensors. This allows the drone to fly up and down when the human operator presses a joystick on a controller, but automatically hover at a fixed distance above the ground when the operator lets go of the joystick. In this project, you will explore drone programming with an Arduino. What types of inputs and sensors can you make your drone respond to? What behaviors and responses can you program… Read more

Seasonal Disease Outbreaks

Science Fair Project Idea

Scientific Method

"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

Testing Gait Symmetry with Uneven Loads

Science Fair Project Idea

Scientific Method

The way humans walk—our gait—is usually fairly symmetrical. Each step we take with the left foot is similar in length and timing to the step with the right foot. This symmetry makes walking efficient and reduces stress on the muscles and joints. But what happens when the body is challenged by an uneven load, such as carrying groceries in one hand or holding a backpack on one shoulder? Biomechanics research shows that unequal weight distribution can disrupt gait symmetry, forcing one… Read more

Delayed Release Pill Challenge: Getting Medicine to the Right Place at the Right Time

Science Fair Project Idea

Engineering Design Process

A lot of medication comes in the form of pills that you need to swallow. But not all pills are the same! Some look like little capsules, others are made of pressed powder. Why are there different types of pills? Different types of pills release their active ingredients in different ways. Some release their active ingredient right after initial administration. Others release their active ingredient much later. Such drugs are called delayed-release drugs. These kinds of pills have to be… Read more

Water to Fuel to Water: The Fuel Cycle of the Future

Science Fair Project Idea

Scientific Method

Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In this… Read more

Make Your Own Psychrometer

Science Fair Project Idea

Scientific Method

From the name, you might guess that a psychrometer is an instrument designed to measure your thoughts. Psych! Actually, it is an instrument that can help you forecast the weather. Read more to find out how it works. Read more
