Smithsonian Education presents Contrasts in Blue: Life on the Caribbean Coral Reef and the Rocky Coast of Maine. Teachers can download this comprehensive teaching package in which students explore two marine ecosystems, the coral reefs of the Caribbean and the state of Maine's rocky coastline. This amazing teaching package comes complete with background information, pictures and maps, student handouts, teacher answer keys, and a list of resources. Through this study students will gain an understanding of our world being one large ecosystem in which seemingly unrelated environments are in fact inevitably linked.
