Five Sites for Environmental Science Fair Project Ideas Article by Mike Lieberman Coming up with a subject for the science fair project (or at least coming up with an interesting one) isn't easy. I entered many science fairs and spent endless hours figuring out what to do. Environmental science was certainly around when I was in school, but the green movement wasn't in full motion. Now that it is there are plenty of "go green" science fair ideas.
Yawning and laughing can be contagious in class Next time you find yourself laughing or yawning in class just because the kid next to you did it first, you can blame nature for it. Yawning and laughing are contagious and there's not much you can do to stop it.
National Mole Day It's National Mole Day on October 23 (and no, we're talking about beauty marks on your skin or those little furry creatures with funky paws.) National Mole Day celebrates the mole the Italian scientist Amedeo Avogadro coined in 1811. The mole, sometimes called Avogadro's Number, is a unit of measurement used in chemistry. And, since this is National Chemistry Month, it is a fitting time to celebrate the mole.
The Chemistry of Baking Cookies Want to wow your chemistry teacher? Bring in a batch of chocolate chip cookies. No, it's not about being the teacher's pet. It's about enjoying the tastier side of science. Baking is all about chemistry and if you're looking for a way to experience it first-hand, chocolate chip cookies are the best way to go.
National Chemistry Week: The Chemistry of Sports Think chemistry and the World Series have nothing in common? Think again. If the ball the pitcher's throwing is too cold, you can forget about watching a homerun—a cold ball won’t spring off the bat as fast as a warm one.
Fascinated by CSI? A Career in Forensic Science Might be for You Have you been hooked by crime scene investigation shows? Do you love watching your favorite detectives solve bizarre crimes using the science of forensics? Thinking about eventually pursuing a career in forensic sciences? Then read on.
