I've had even worse luck trying to convince people that trees are mostly made from air and water.
- lkbm 12y agoThere's a nice Veritasium episode wherein he asks people on the street where a tree's mass comes from: https://www.youtube.com/watch?v=2KZb2_vcNTg https://www.youtube.com/watch?v=2KZb2_vcNTg (This isn't just one of those "let's laugh at how dumb people on the street are" videos; it's done explicitly as a learning exercise. His PhD looked at how addressing misconceptions and going from there to correct explanations works much better than simply providing explanations: https://www.youtube.com/watch?v=RQaW2bFieo8 https://www.youtube.com/watch?v=RQaW2bFieo8 ) I thought of it upon seeing the first chart in the BMJ article.)
- JoeAltmaier 12y agoLet me guess: mostly from water? And the air of course - carbon. Sorry, I won't watch the video, its far too spare a use of time.
- lkbm 12y agoHe pretty much just says carbon. Certainly is some water involved too, but yeah, breath in CO2 and breath out just O2.
