For more than two decades, Castro Valley Sanitary District (CVSan) has proudly offered its 4Rs Field Trip for third graders. Students arrive at CVSan offices where they learn about the 4Rs (Reduce, Reuse, Recycle, and Rot), how to properly sort solid waste, as well as how to make their own recycled paper! This fun-filled 2-hour field trip is offered free to Castro Valley schools. Free bus transportation may be coordinated with all schools.
See below for links to the pre and post-field trip lessons as well as a class roster sheet. Registration for the 2020-2021 School Year is pending.
