This week in science students put on their Science Notebooking
Cap and participated in a very engaging lesson.
Yesterday, students wrote predictions about what they thought would
happen when they put water in a cup, added food coloring, and then placed a
celery stock in it. After completing their
hypothesis, students conducted the experiment.
This morning students observed what happened to the celery over night. Many students were surprised and excited to
see that the celery and the celery leaves changed color to match the colored
water. Students learned that the celery
and leaf color changed due to the xylem.
The xylem acted like a straw; it sucked up the colored water and
delivered it to the celery leaves.
Students connected the celery experiment to plants. When we water the soil of a plant, the water
is sucked up through the xylem and delivered to different parts of a
plant. Photographs from our experiment
are below.
Very cool experiment! I used to teach plants when I was a 4th grade teacher. I wonder if you could make a white carnation turn blue?
