Developed to complement existing elementary science programs, the materials in this second volume of New York's Elementary Science Supplement emphasize an experiential, hands-on approach for children aged 7-9. Major sections include guidelines for program activities, (the format of this publication); correlating syllabus and program, (including a chart which correlates skills, processes and attitudes with the units of the program); and program activities, (indicating syllabus emphasis, problem overview, suggested approach, materials, discussion notes, and supplementary information for four units, four mini-units, and 16 unit-starters). Appendices include "Students with Handicapping Conditions" and a blank "Syllabus-Program Correlation Chart for Level II." Topics covered in this guide include buoyancy, electricity, life cycles, energy, and ecology. (CW)
