Lesson Plans for the Lophelia II 2009: Deepwater Coral Expedition: Reefs, Rigs, and Wrecks Expedition

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 2009: Deepwater Coral Expedition: Reefs, Rigs, and Wrecks. These lesson plans focus on cutting-edge ocean exploration and research using state-of-the-art technologies.

The lesson plans are grouped into the following categories:

Diamond Icon Grades 5-6
Diamond Icon Grades 7-8

Diamond Icon Other Relevant Lessons

In addition to being tied to the National Science Education Standards and the Ocean Literacy Essential Principles and Fundamental Concepts, the hands-on, inquiry-based activities 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 daily logs from the Lophelia II 2009 expedition, which are posted on this site, to supplement the lesson plans.
