Growth of 7 Beans

Seven beans in seven different baggies taped to my classroom window all on the same day.   In the baggie is a wet paper towel with the bean.  A common classroom experiment to watch how a bean can sprout without dirt.  After a few weeks we were done with the experiment and I took the baggies off the window and was going to throw them away.  I had the tiny plants all in a pile in front of me and noticed how they had all advanced to different stages of growth.  I lined them all up on a piece of construction paper for the kids to view.  Then took a picture.  I really like this for some reason.
