The girls had a fun time watching the celery veins change colors over night. This science experiment is an example of absorption. They learned that the stem of the celery stalk soaks up water through the ground to survive. When we cut the stalks in half the girls noticed that the colored water was sucked up through little holes in the stalk. The veins in the leaves also turned a color.
The data was recorded over a three day period using this data record observation form from
ABCteach.
