colored leaves experiment

the girls were learning about controls in regards to scientific investigations.
we put red food coloring in the water of one jar
and left the other as a control, a test that other tests are compared to.
over a period of four days
we watched what happened to the celery in the red dye
vice the control in plain water.
our results agreed with our hypothesis:
the leaves of the celery in the red dye gradually gained a red tint.
