It's Okay To Be Smart!
I found a great producer of science videos as I was searching for information about geologic eras the other night - It's Okay To Be Smart. A PBS production with host Joe Hanson, Ph.D, many of the topics we are studying are discussed here. I highly recommend checking out their channel on YouTube - you have no idea what you might learn! Here's the one we watched in class the other day, just in case you want to see it again.
