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

Feel Sound With Your Fingertips: Ultrasonic Haptics

Science Fair Project Idea

Scientific Method

Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair. Read more

Make Your Own Low-Power AM Radio Transmitter

Science Fair Project Idea

Scientific Method

Have you ever wondered how an AM radio station works? In this project you will learn the basics of how your favorite songs are transmitted by a radio station, by building your own simple AM radio transmitter. You will learn the basics of how a transmitter works, and how you are able to tune to your favorite station and listen to music. Read more

Make an Automatic Evaporative Cooling System

Science Fair Project Idea

Engineering Design Process

You probably know that sweat helps cool your skin on a hot day because of evaporation. But do you think you can use evaporation to cool a building? Evaporative cooling systems could provide a more environmentally-friendly alternative to traditional air conditioning. In this engineering project you will build and try to optimize your own model evaporative cooling system. Read more

Monitor Your Plants with a Soil Moisture Sensor

Science Fair Project Idea

Scientific Method

Do you or your family have a lawn, garden, or potted plants that you water regularly? Irrigation—or the artificial application of water to plants and landscaping—accounts for over two-thirds of the world's freshwater consumption (U.S. Geological Survey, 2016)! While that total includes farms, in the United States landscape irrigation still accounts for almost one-third of residential water use. As much as half of that water is wasted due to inefficient watering methods (WaterSense,… Read more

Build a Haptic Glove with Arduino

Science Fair Project Idea

Engineering Design Process

Have you ever used a video game or virtual reality (VR) controller that vibrates? The controller might vibrate when your character gets hit or when you crash in a racing game. This vibration provides additional information to your senses to help you understand what is happening in the game. What if you could feel these vibrations at different points on your skin through something you wear, like a glove? In this project, you will learn how to build and program your own customized glove with the… Read more

Build an Automatic Dog (or Cat) Treat Dispenser

Science Fair Project Idea

Engineering Design Process

Does your dog get bored when you are not home? Do you ever toss them a few treats right before you head out the door? What if you could keep them busy by automatically dispensing treats throughout the day? What about training them to sit in a certain place or even press a button by automatically rewarding them with treats? In this project you will build your own automatic dog (or cat, or other pet) treat dispenser that you can customize to react to different sensors. 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

Design a Wearable Air Quality Index Monitor

Science Fair Project Idea

Engineering Design Process

You can look up information about local air pollution, such as the Air Quality Index (AQI), online or even get alerts on your phone. But what if you could wear a device that continuously monitors the air quality around you in real time, alerting you to unsafe levels? Such a device could alert a person with asthma when they need to go inside, let you know if smoke from a nearby wildfire is drifting in your direction, or signal when it is time to take a break on a hazy summer day. The Science… Read more

Design Your Own Smart LED Lighting System

Science Fair Project Idea

Engineering Design Process

Have you ever had lights turn on automatically when you walked into a room? Have you turned on a light with your voice instead of a switch? Maybe you have even seen lights that change color depending on temperature, ambient sounds, or how close you are to something. In this project you will design and build your own smart LED lighting system that can change colors and react to various things in the room. The possibilities are endless! Check out this page for more LED science projects. Read more
