Does Your Mobile Phone Radiate? Measuring Cell Phone Electromagnetic Radiation

Science Fair Project Idea

Scientific Method

Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for more than just making calls though. They use them for texting and searching the Internet, too. But some health groups are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics science project, you will investigate how much radiation your cell phone emits when used… Read more

Engineer an LED Night-Light

Science Fair Project Idea

Engineering Design Process

Night-lights can be found in many homes; you might even have one in your bedroom! Using a night-light is a great way to avoid stubbing your toe on furniture during a midnight trip to the bathroom. In this fun engineering project, you will design and build your own night-light. You will need to build the circuit, but you will also need to think about the physical design of the product. Most people probably do not want an ugly, bare circuit board sitting around their house. Can you make a… Read more

Make a Pomodoro Study Clock

Science Fair Project Idea

Engineering Design Process

The Pomodoro technique is a popular study method consisting of alternating study sessions and breaks. In this engineering project you will build your own customized Pomodoro timer or clock using an Arduino. In addition to displaying the time, you can use your clock to display messages or get the user's attention using lights, sound, or even moving parts. Can you work more efficiently with a Pomodoro timer at your side? Build one and find out! Read more

Motorized Arduino Cable-Driven Spacecraft Motion Simulator

Science Fair Project Idea

Engineering Design Process

How do you practice docking a spacecraft with the International Space Station or landing on Mars? With a room-sized cable-driven spacecraft motion simulator! In this project, you will build your own miniature, motorized version of a full-sized motion simulator scientists are developing that can move model spacecraft around in a controlled manner.

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

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

Smart Medicine Cabinet: Build a Sensor That Reminds Patients When to Take Medication

Science Fair Project Idea

Scientific Method

Have you ever had to take prescription medicine to get over an illness? To get better, it is important to take the medication in the proper manner and at the proper time. Wouldn't it be cool if there were a tool or piece of automated equipment that held your medicine and reminded you to take it? A tool that would know when you picked up the bottle and took your medicine? Building a smart medicine cabinet is what this science project is all about! Read more

Build a Light-Up Activity Timer

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
