Teachers on the Estuary (TOTE) is a 4-day field- and research-based summer workshop designed for middle and high school science teachers. The workshop aims to improve teacher and student understanding of the environment using local examples, and to provide resources and experience to support the incorporation of climate change, ecosystem services, systems thinking, service learning, estuary and watershed topics into classroom teaching. The course is also designed to promote stewardship of watersheds and estuaries. Following the summer workshop, teachers implement a stewardship project with students throughout the school year, using a $200 mini-grant through TOTE. Teachers also commit to attending a half-day fall follow up session to report on their stewardship project progress.
