Reported is a project designed to correlate six units of study from the Philadelphia Elementary Science Guide and to incorporate them in such a way as to reduce the suggested 32 weeks of teaching time, for the individual units, to 10 weeks for all 6 units. This was necessitated by an interruption of the school year by a teachers' strike. Three objectives guided the project: (1) to insure that children would obtain the basic science skills contained in the Elementary Science Primary Unit of the Philadelphia Public Schools, (2) to enrich the scientific course of study, and (3) to test the worth of open classroom techniques in a traditional setting. The major objective for the teachers was to extend the knowledge of newly developed scientific concepts wherein it might enable them to better prepare their pupils to meet the scientific age. Descriptive information is provided for the Primary Science Unit and the Primary Ecology Unit, including concepts involved, steps of organization, correlation of subject matter, and culminating activities for each of the two units. Appendices to the report contain such materials as vocabulary lists, activity sheets, games, maps, and other related activities. (PEB)
