For a school, knowledge is life, even though these two concepts are diametrically opposed in the Garden of Eden.  This tree, which is half white, half black, joins the two opposites.  Ten pomegranates, arranged in a circle, contain the symbols of the branches of knowledge taught at Heschel School.  The inscription, from Pirket Avot, translates, "Without knowledge there is no understanding.  Without understanding, there is no knowledge."
