After completing their science unit on the parts of the plant, fourth-graders at Deauville Gardens East Elementary School participated in a two-day experiment to show the workings of vascular plants. Using stalks of celery, the students placed the plants in colored water to observe the way the celery absorbs water and transports it through its stem. After making their initial hypotheses, the students recorded the changes in the coloration of the celery on day one and day two.
