These educational resources from the National Ocean and Atmospheric Administration (NOAA), the National Ocean Service (NOS), and the United States Department of Commerce will be a welcome find for educators teaching earth sciences to elementary school students. Here readers will find visualizations, videos, interactive games, lessons, posters, presentations, and audio archives on a broad range of ocean related topics. Educators may like to scout the site by grade level or by media type. The Lessons section is especially robust, with over 100 professionally structured lessons on such topics such as Aquatic Food Chains, Climate Change, Coral Reef Habitat, Island Formations, Humpback Whales, Ocean Geography and Geology, and many more. Each lesson features a descriptive introduction that outlines the approach and learning goals, clarity about the targeted age group, reference to National Standards and Hawaii State Standards, and in-depth descriptions of learning activities. For teachers introducing students to the life of the ocean, this website will not disappoint.
