Back in the day (or a couple of years ago) I used to post lots of cool science videos on this site. I got away from that in order to focus on more “important” science education resources. Well- I think it’s time to start sprinkling in some fun science videos again. So here we go. This is not a brand new video but it is cool. Here is Travel Deep Inside a Leaf courtesy of California Academy of Sciences. Feels like it could be useful for high school biology and thinking about Scale, Proportion, & Quantity.
