The 4th Grade students investigated how water moves through plant stems. First, the girls filled up two cups with water adding red food coloring to one cup and blue food coloring to the other cup. Next, they split a celery stalk from the middle to the bottom. Then, they placed one side of the celery stem into the red water and one side of the celery stem into the blue water. The girls predicted what they thought would happen over the weekend. On Monday we went to observe what happened to the celery’s leaves. The girls found that half of the celery’s leaves were red and half were blue. The girls concluded that plant stems help take water and nutrients to the other parts of the plant.
