On Wednesday of this week first graders learned more about the importance of, and jobs of, the stems of plants. Ask them to explain! We then set up an experiment to help us see one of the stem's jobs in action. We took celery and white daisies and put them in colored water over night. We had learned that the stems act as straws and suck water up into the rest of the parts of the plant, so we predicted that we might see some color up in the leaves and petals the next day. And we were right!
