Lophelia II 2012: Deepwater Platform Corals

Classroom Lessons

Educators and scientists working with NOAA developed a series of lesson plans for students in Grades 5 - 12 that are specifically tied to the science behind the Lophelia II 2012: Deepwater Platform Corals expedition. These lesson plans focus on cutting-edge ocean exploration and research using state-of-the-art technologies.

Activities are correlated with A Framework for K-12 Science Education (in preparation for the Next Generation Science Standards); the Ocean Literacy Essential Principles and Fundamental Concepts; and the Common Core State Standards for English Language Arts and Mathematics where appropriate. The lessons include focus questions, background information for teachers, links to interesting Internet sites, and extensions. Web logs that document the latest discoveries and complement the lesson plans, complete with compelling images and video, will be sent back each day from sea. Teachers are encouraged to use the background essays, logs, and other resources from the Lophelia II 2012 expedition posted on this site to supplement the lesson plans.
