Public school science instruction, research in science curriculum development, and inservice training for science teachers is planned for one central facility. Concentrated natural science courses using science equipment not ordinarily available in schools will be offered to all pupils, 4th through 12th grade, of Philadelphia area school systems. The recommended site is chosen for proximity to the new university science center and easy access to traffic routes serving the full area. As students are to be bused from their regular schools, a subterranean, multistory parking facility located beneath the instructional building is planned. Schematic diagrams of specialized laboratories, classrooms, lecture halls, materials centers and planetarium are included. Appendices contain lists of advisory board personnel, chronology for development of the center, and a schedule of estimated annual and five year operating costs. (RLP)
