Students at the Bergen County High School of Jewish Studies participated in Mitzvah Day this past Sunday. A group of students went to the Jewish Federation of Northern New Jersey where they packed activity bags for teens battling cancer, sorted and packed baby clothing to be sent to Israel, made chew toys for a local dog shelter and made memory books for Alzheimer’s patients. A second group of students went to Mevo Fresh Roots Farm in Mahwah to plant, weed and prepare the ground for the upcoming winter season.
