Jamie has recently been talking a lot about wanting to be a scientist (usually a paleontologist) and asking to do experiments. We've done several small, quick "experiments," but the best one by far has been growing a bean on a wet paper towel. We just used a dried pinto bean from a bag we already had in the cupboard and set the jar in Jamie's window every morning. He loved checking on it each night and putting it back each morning. I don't know for sure when we started but it was some time in January and we just finally pronounced the experiment finished last week when the leaves started drying out and the roots started turning black. It was so neat to watch all that time.
