Build an Obstacle-Detecting Walking Stick for Blind People

Science Fair Project Idea

Engineering Design Process

Many individuals who are blind or visually impaired use canes to navigate their surroundings, using their sense of touch to detect obstacles. What if you could create an electronic cane that emits an audible warning before coming into contact with an object? This project allows you to do just that by incorporating an ultrasonic distance sensor and a buzzer to alert the user of approaching obstacles. You can customize the cane by adding additional features or altering the design, such as using a… Read more

Build an Ultrasonic Levitator

Science Fair Project Idea

Engineering Design Process

It's not magic; it's science! Build your own acoustic levitator to make objects float in midair using invisible sound waves. Read more

Build and Test a Sun-Tracking Solar Panel

Science Fair Project Idea

Scientific Method

How can you get as much power as possible out of a solar panel, even in the morning or evening when the sun is low in the sky? With a solar tracker system! While many solar panels are fixed in place on rooftops or large ground-mounted poles, a solar tracker system is motorized and lets the solar panels track the sun through the sky during the day. Are these systems worth the added complexity? How much more power do they produce? Try this project and find out! Read more

Build Obstacle-Detecting Glasses for Visually Impaired People

Science Fair Project Idea

Engineering Design Process

Many visually impaired people use canes to detect obstacles at ground level. What about detecting an obstacle at face level, like a tree branch? What if you need to keep both your hands free and cannot hold a cane? Solve both problems at once with these obstacle-detecting glasses! The glasses use an ultrasonic sensor to measure distance and a buzzer to alert the user of nearby objects. You can customize the design to add or swap out features, like using a vibration motor instead of a buzzer.… Read more

Build Your Own Super-sensitive Electric Field Detector

Science Fair Project Idea

Scientific Method

Wouldn't it be nice to avoid those nasty electric shocks you get after you have walked around on carpet and then touch a doorknob? These shocks are caused by static electricity. In this project, you will build a super-sensitive charge detector to investigate the electric fields created by static electricity. The detector can sense invisible electric fields before you touch something and get zapped, so try this project to avoid the shock of shocks! Read more

Dealing with Diabetes: The Road to Developing an Artificial Pancreas

Science Fair Project Idea

Engineering Design Process

Imagine if you had to take medicine every time you ate, and you had to use a math formula to figure out how much medicine to take based on the nutritional makeup of the food, how you were feeling, and what activities you were planning to do. You might also need extra medicine throughout the day (even in the middle of the night) based on your blood glucose levels. People with diabetes who take insulin do this every day. They use finger sticks and blood glucose meters or a continuous glucose… 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

Electric Play Dough Project 1: Make Your Play Dough Light Up & Buzz!

Science Fair Project Idea

Scientific Method

Do you like playing with play dough; or modeling clay? Wouldn't it be cool if you could add lights, sound, or even motion to your play dough creations? In this project, you will use play dough that conducts electricity, which will allow you to connect lights to your sculptures! This project is the first in a three-part series on play dough circuits, which can all be done with the same materials. We recommend doing the projects in order. Read more

Electric Play Dough Project 2: Rig Your Creations With Lots of Lights!

Science Fair Project Idea

Scientific Method

Have you tried our first electric play dough project, and now you are looking for more to do? Do you want to learn more about circuits and add even more lights? Check out this project for part 2 of our play dough circuits series! Read more

Electric Play Dough Project 3: Light Up Your Sculptures!

Science Fair Project Idea

Scientific Method

Have you tried our first and second play dough circuits projects? Are you a master circuit artist, ready to try something even bigger and better? Try this project to see if you can build a three-dimensional light-up sculpture. Read more
