Imagine trying to put a solar panel on your roof or outside your home to generate clean, renewable energy. Where would you put it so it generates as much power as possible throughout the day? What direction should it face? Is there a way to take measurements to find the best location before you install the panel? In this project, you will use a tiny programmable device called a micro:bit to record light data and find the best place to put your panel.

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…

It's fun to host and attend parties. You can meet your friends, watch movies, and eat party food. Another thing that people like to do at parties is dance to music. Dancing is great exercise and just makes people happy. What if at the next party you attend, you could do your science fair project? Doesn't sound like a good idea? Well, in this electricity and electronics science fair project, you will make a dance pad that flashes lights when you step on it. Have your friends test it out for you.…

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!

The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project.
The project has you use a strobe light app on your phone. The advantage…

Solar cells are devices that can be used as a source of power when there is light shining on them, but they stop producing energy when they are not in the light. One way to store the solar energy for later use is to use a solar cell to charge something called a capacitor. The capacitor stores the energy as an electric field, which can be tapped into at any time, in or out of light. In this electronics science project, you will use parts of a solar car to experiment with the energy storage…

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!

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…

Water is an interesting thing. We drink it, swim in it, and wash ourselves with it. We can get energy from
water by damming it and sending it through a turbine. But did you know that we can use the natural electrical
charges present in water and a Kelvin electrostatic generator to create sparks? You can even use a
Kelvin electrostatic generator to temporarily light a bulb! Now that is one bright idea!

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…
