Letourneau, Stephanie

Abstract

Grade Level: 7th grade. Travel in time on Maine’s coastline to understand species and environmental changes in the intertidal zone. In this interactive lesson, students will simulate monitoring using quadrats to quantify the amount of sea stars, estimate percent cover of blue mussels, and evaluate community shifts from 1979 to 2021. Focus: Understand the role of keystone species and how to determine percent cover.
