These materials were developed to meet an expressed need for bilingual materials for a secondary school Life Science Course. Eight units were prepared. These include the following topics: (1) Introduction to the Scientific Method; (2) The Microscope; (3) The Cell; (4) Single-celled Protists, Plants, and Animals; (5) Multicellular Living Things; (6) Plants; (7) Animals; and (8) Genetics. Included are objectives, background material, lesson plans, evaluation materials, and activities. Many of these can be duplicated for classroom use. (RH)
