So I did present at Barrow Elementary on Feb. 26. I spoke for about 20 min. about microbial fuel cells and using leachate as a substrate. Then, we had about 40 min. of question and answer time. I got some of the best questions I have ever gotten from 9 year olds. Really. Their freedom to ask anything and unbridled inquiry was incredible! They wrote me thank you cards, but I am grateful to them. It was a truly rewarding experience.
