This up-to-date Canadian website aims to teach students how oceans, humans, and the environment are interconnected. A free online course, the materials are divided into seven sections, or principles, and students can work at their own pace through each section, exploring the various topics through games, hands-on activities, videos, and quizzes. A resource section for teachers includes worksheets, content-related articles, lesson plans, Indigneous knowledge resources, online games, and other support materials. Teachers could use this website to teach an entire ocean unit, or use the materials to supplement their own science units. Log in to read the full review.
