What do you think about killing vampires? No, no, not the kind that drink people's blood, but the kind that suck your power and money away. Equipment like televisions, computers, printers, and fax machines all use electricity to operate, of course, but do you realize that this equipment might still be sucking electricity from the wall, even when you think it's turned off? These electricity-suckers are called vampire loads. In this science project, you will investigate how much power these… Read more

What would you do if you saw one of your friends lying on the floor, not breathing, possibly having a heart attack? Call 911? Start CPR (cardiopulmonary resuscitation)? Those would both be important things to do! But do you know CPR? Do your friends and family know CPR? Chances are, most of them don't. Even if they do know CPR, they might be hesitant to use their mouths to perform it. You can change that though. In this science project, you'll create a simple, interactive game that can teach… Read more
