This isn’t just another elementary school festival: P.S. 75 has organized a health fair and a green fair in addition to the traditional games and crafts-based revelry. At the health fair, families can receive free health screenings and pick up tips on wholesome eating and exercise. The green fair includes an e-cycling drive, so bring computers, cell phones and other electronics to recycle. Follow the sound of DJ music and the scent of international food if your family wants to partake in the old-fashioned kind of fair fun. Free. All ages.
