We set this up over breakfast to talk about how plants breathe in carbon dioxide and emit oxygen.
Even on an overcast day, it only takes a half hour to produce water vapor.

We combined this with our Earth Day projects and the very sweet book, The Mighty Tree https://www.amazon.ca/Mighty-Tree-Dick-Gackenbach/dp/0152005196/ref=sr_1_5?ie=UTF8&qid=1461370471&sr=8-5&keywords=the+mighty+tree
