Customize Your Own Drum Set!
Science Fair Project Idea
What kind of music do you enjoy listening to? Hip hop, rap, classical, techno, or electronic? Do you know what most of them have in common? They rely on a drumbeat to provide tempo and depth to the sound. You might think of a drum as simply a large round vessel with a membrane covering that musicians strike with a drumstick, but musicians can create a synthesized drumbeat with an electronic keyboard or with electronic drums. In this science project, you will design and make your own… Read more

Feel Free to Sleep at School... If You're a Computer!
Science Fair Project Idea
Sleeping in class isn't allowed... unless you're a computer! In fact, the Environmental Protection Agency (EPA) suggests that putting your school's computers to sleep when they're not in use might reduce a school's energy bill significantly. In a study done at the North Thurston public schools in Olympia, Washington, EPA officials worked with the district to cut computer energy and costs by approximately $45,000 annually! How? By implementing a variety of power-management strategies for the… Read more

Game of Life
Science Fair Project Idea
The Game of Life is the invention of the mathematician John Conway. It is a cellular automaton, consisting of a grid of squares that turn "on" or "off" depending on simple mathematical rules that involve neighboring squares. Depending on how the grid is first set up (i.e., the initial conditions), various interesting patterns appear. Can you write a Game of Life program (in JavaScript or any other computer language of your choice)? Can you think of ways to alter the rules that result in… Read more

How Secure Are Your Security Questions?
Science Fair Project Idea
Many websites ask you to answer "security questions," like "What is your mother's maiden name?," to recover your account if you ever forget your password or login ID. However, sometimes the answers to those questions are easy to find online. Does this pose a risk to the security of important accounts like email and online banking? Are people even aware that this information about them is available online? In this project, you will investigate how secure people think security questions are, and… Read more

Keeping It Private: Blocking RFID Readers from Reading your ID Card
Science Fair Project Idea
If you've ever watched an adult pay for something by simply touching their credit card to a machine at a store, or you've done the same with a bus pass, you've seen an RFID tag in action. An RFID (Radio-Frequency IDentification) tag allows a card to be read by a computer from a short distance away. This is very convenient, but it also allows criminals to steal information about you. For instance, on the subway or the bus, someone standing next to you can use an RFID reader to access the data on… Read more
