Bad science (also known as junk science, science myths or science misconceptions) consists of common misconceptions passed on from parents, teachers and inaccurate text books. As American scientist Stephen Jay Gould said, "The most erroneous stories are t
Hands-on science experiments at home or in the classroom are a fun way to engage kids and get them excited about science. Today's sites house hundreds of easy experiments that can be done with supplies that you probably have around the house, or can get a
The science of sound can be explored at many different levels, from grade school to college physics. Whether your interest is in making drums with first graders, or doing research for a physics project, this week's site selections will deliver with anima
It's summertime and we're taking a virtual trip to the amusement park. But on this trip we're combing fun and thrills with science, as we take a look at the physics behind your favorite theme park rides.
To understand the science of colors, we must first know something about the nature of light. Light is an energy source that behaves like a wave. The distance between the each wave is called the wavelength. Light of different wavelengths appear as differen
Each year there's another batch of science fair pleas in my mailbox. "Help! My daughter (or son) needs a science fair project. Can you suggest one?" Each year, my answer is always the same: no. I make a point of not doing my own kids' schoolwork -- so don
