They develop an awareness of living things and their basic needs. The unit concludes with a series of activities related to the Chesapeake Bay. Ecosystems was developed by the National Science Resources Center with support from the National Academy of Sciences and the Smithsonian Institution. This web site offers a place to obtain information and ideas that help educators explore the environment and investigate current issues with students.
