I use a lot of activities from the Mailbox, but this is one every year that I feel like The Mailbox doesn't do a good enough job with documentation. So, this activity is to go along with the experiment where you take a bean, put it in paper towel, and watch it grow, then turn it upside down to see if you can fool it.
The document is for students to fill out their observations. They write about what the bean looks like initially, and then document every time there is a significant change. They write about it, measure it, and also draw what it looks like.
