Crash Course Biology videos

Just wanted to share a favorite resource for science...Crash Course videos on YouTube!! My favorite ones are the biology and A&P with Hank (of the Dear Hank & John podcast fame!) These videos are packed full of information in a very easy to understand way--lots of pictures, explanations, and humor! :) 

Here are two for examples: https://www.youtube.com/watch?v=X9ZZ6tcxArI&t=25s (about the heart) and https://www.youtube.com/watch?v=WtrYotjYvtU (about the excretory system). 

I use these when I'm tutoring or teaching and also I have recommended them to college students struggling in different areas of biology--they are SUPER helpful!

Check them out! :)
