Feeding Fido & Fluffy: Designing an Automatic Pet Feeder

Science Fair Project Idea

Scientific Method

An overnight trip to the beach or a quick two-day vacation can be lots of fun. What do you do to prepare? Pack your clothes, get sunscreen lotion, and borrow a book from the library. But wait!

Feel Free to Sleep at School... If You're a Computer!

Science Fair Project Idea

Scientific Method

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.

By implementing a variety of power-management strategies for the… Read more

Fighting Litter in Your Neighborhood

Science Fair Project Idea

Scientific Method

Is there a public park, playground, or beach near you that suffers from a litter problem? Here is a way that you can do something about it! First, get a measure of the size of the problem by conducting a litter survey. Select a fraction of the area to survey at regular intervals (e.g., every two or three days, or maybe once a week). The area should be large enough so that you can get a representative sample of litter, but not so large that you can't clean it up. Each time you conduct your… Read more
