A Stem Experiment
Materials:
Food color and a stalk of celery
Procedure:
Leave the leaves and cut the stalk at an angle at the base. Put it in a glass with at least several inches of dark colored water and ask students to predict what will happen in writing with a short simple sentence. You might start noticing the colored water rising in a hour or two.
Close:
When all the students agree that the water is going up the stem have the students write descriptions of what happened. Have the students draw pictures of plants that label the roots, stems and leaves. Stems carry minerals up from the roots in the soil to the leaves on top.
