To assist school districts in selecting science instructional materials, the California State Department of Education has developed detailed descriptions of state-adopted elementary programs and texts. This guide includes an annotated index of all adopted materials and separate descriptions for each program or series. The index contains a listing of the program's title, copyright year, grade levels and readability levels. Each program description includes sections on: (1) contents coverage (addressing the areas of science, technology, and society and the biological, earth, and physical sciences); (2) teaching and learning activities; (3) organization of topics and activities; (4) ancillary materials; (5) teacher materials; (6) assessment and evaluation techniques; (7) implementation requirements; and (8) areas needing supplementation.
