Thirty-one state guides, published or revised between 1955 and 1964, were studied to examine (1) the major areas of science included, (2) the sequence of presentation by grades, (3) the recommended science concepts to be taught at each grade level, (4) the stated objectives of elementary school science as revealed by the guides, and (5) laboratory experiences recommended for elementary science. Analyses indicated that some guides omitted one or more major areas of science, and subject matter coverage was not considered universally adequate. Many concepts were suggested, while few were supported by sufficient laboratory experiences. (BC)
