This is a series of science experiments in videos covering concepts taught in Schools and High Schools.
Entropy - Science Theater 39
Entropy. It's why everything seems to break down and get messy. It is something that comes about when you have lots and lots of little things (like atoms) that can be in several possible "states" (no, not Florida). The more things or more states you have, the more entropy you're going to have. Dr. Carlson has entirely too much fun playing with coins and blocks while he tries to explain how Chemists think of Entropy. (Stay to the end and you'll even see a rubber band, whee!)
Do you have what it takes to explain science? Try to explain how this object actually rolls uphill in this episode. This video is the first of several Brainteaser episodes where you, the viewer, are presented with a problem and are challenged to explain the science behind the solution by the end of the episode.
A Straight Line
Is the best path between two points a straight line? The second video in our brainteaser series challenges the viewer (you) to predict and explain any differences in the path of two rolling balls. Can you figure it out before the episode is over?
