Science Fair Project Idea

Engineering Design Process

Do you have trouble remembering when to stop playing and clean up? Have you ever had little kids throw a tantrum about cleaning up while you were babysitting? If so, this project is for you! You will convert a stuffed animal into a light-up activity timer. You can use the timer for different activities like play, exercise, or doing homework. What you use it for is up to you! Read more

Build a Wearable Device Using an Arduino to Keep Astronauts Safe on Mars

Science Fair Project Idea

Engineering Design Process

Astronauts on Mars missions must be protected from hazardous environments, like steep cliffs, rocky terrain, and extreme temperature variations. How can geofencing help? In this project, you will design a system that uses geofencing technology coupled with biosensors to ensure astronaut safety. The system will create a virtual boundary around astronauts, providing alerts if they approach dangerous areas or leave designated safe zones, or if their vital signs fall below a certain threshold. Can… Read more

Color Mixing with Red, Green, & Blue LEDs

Science Fair Project Idea

Scientific Method

This is a good project for someone who is interested in both electronics and color vision. The equipment needed is on the expensive side, but if you continue studying electronics, you can use it again and again. 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 Clothing with Built-In Sensors

Science Fair Project Idea

Engineering Design Process

Have you ever worn a costume that lit up or played sound? Have you ever wished you had a suit of armor with built-in moving parts like a superhero? What if you could make your costume or suit react to your own movements or even other people who bump into you? The Science Buddies activity Weaving a Wearable Touch Sensor shows you how to make a capacitive sensor that responds to touch and can be woven directly into fabric (Figure 1). Can you design a piece of clothing that includes one… Read more

How Do You Know Where You Are Without GPS? Dead Reckoning and Inertial Navigation

Science Fair Project Idea

Engineering Design Process

Put a meter stick on the ground. Starting at one end of the stick, close your eyes and try to walk exactly one meter. Open your eyes. How close were you? Now try it again with five, ten, or twenty meters. Does it get harder as the distance gets bigger? Without an outside reference from your visual system, it's quite difficult to know exactly how far you've gone! Electronic navigation systems face the same problem. Without an external reference like the global positioning system (GPS), it's very… Read more

How Long Does It Take to Fry a Diode?

Science Fair Project Idea

Scientific Method

If you have ever built an electronic circuit with a soldering iron, you know that the component leads get hot. How much of that heat gets into the device you're soldering? This project shows you how you can use a silicon diode as a temperature sensor to find out. Read more

Nanotechnology in Action: Organic Electronics

Lesson Plan Grade: 9th-12th

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an… Read more

You might have read about the negative impacts modern human civilization has had on the environment, like pollution, deforestation, and extinction of animal species. How can we use modern technology to help protect the environment? In this project-based lesson students will design an electronic circuit that can measure something in the environment like water quality and light pollution, and develop a plan for how their circuits could be used to solve a real-world problem.

HS-ESS3-4. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Simple Circuit Logic with Switches: An Electric Puzzle

Science Fair Project Idea

Scientific Method

Here's a puzzle you may have heard before which you can build as a simple electric circuit. First, the puzzle: a farmer is traveling to market with his cat, a chicken and some corn. He has to cross a river, and the only way to cross is in a small boat which can hold the farmer and just one of the three items he has with him. The problem is, he has to be very careful about what he chooses to leave behind at any time. If the cat and chicken are left alone, the cat will eat the chicken. If… Read more
