thumbnail So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get… Read more

thumbnail Have you ever walked a dog on a leash? Depending on how well-behaved the dog is, it can be very easy or very difficult. It would be great if you could tell your dog exactly how to behave, right? With that in mind, in this project you will build a robotic dog using a LEGO® Mindstorms® kit that you can teach to "walk" using the beam from a flashlight as a virtual leash. But your robot dog will not know how to walk on a leash on its own — you will have to "train" it, just as you… Read more

Science Fair Project Idea
Have you ever played a video game and gotten so involved that you felt as if you were living inside the game? What were the characteristics of the game that made you feel part of the action? One component of an absorbing video game is an onscreen world that makes sense—a world that takes physics into account. A game in which the player feels the effect of trudging through mud, slipping on ice, or catapulting a bird is more fun than one with no environmental interaction. In this… Read more

thumbnail In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals can't rely on sight. Did you know that you can also build a robot that uses whiskers to find its way around? This science project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

thumbnail Extinct might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they're in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It's a lot… Read more
