As part of a language arts series for kindergarten through grade nine, this seventh grade guide examines environmental values, concepts, and problems according to a common conceptual scheme: all living things, including humans, are interrelated and interdependent; heredity and environment interact to determine the characteristics of an organism and therefore a population; living things and environments are in a continuous state of change; the world has finite resources and almost infinite demands are made on these resources; and each individual, as an agent of change, has a responsbility to the environment. The guide emphasizes the discovery process of observation and offers a series of environmental activities in the language arts areas of biography, creative writing, journalism, oral communication, poetry, reading, the short story, and spelling. The guide includes background information, a teacher outline, and task sheets for the students. (MAI)
