The Speed of Light: Explore Solar Energy with a Supercapacitor Car Motor!

Science Fair Project Idea

Scientific Method

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… Read more

Abracadabra! Levitating with Eddy Currents!

Science Fair Project Idea

Scientific Method

Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! Read more

Program a Sound Level Meter to Help Protect Your Hearing

Science Fair Project Idea

Engineering Design Process

Have you ever said, "That hurt my ears!" when someone yelled loudly right next to you? Do you cover your ears when a fire truck drives by with the sirens blaring? It is good to protect your ears—even sounds that do not "hurt" can cause hearing damage if you are exposed to them for too long. In this project, you will program a device that alerts you when sounds have exceeded safe levels long enough to cause hearing damage. Read more
