Understanding Ocean & Coastal Acidification: For Teachers

Through the lessons in this module, designed for grades 9-12, students will explore relationships between carbon dioxide, ocean pH and aragonite saturation state. By examining these parameters using interactive graphs and models, students can predict whether ocean conditions support the growth and survival of shell-building marine life, both now and in the future. The module offers lessons at five different levels, beginning with basic graph interpretation (Levels 1 & 2) and building towards activities that challenge students to ask questions and develop their own data investigations (Levels 4 & 5).
