This document, which reviews national, state, and local science activities and programs, provides educators with concrete examples of varied science programs that are a valuable resource for teaching science skills and proficiencies. This resource guide is intended to help educators supplement, amend, and revise their elementary science programs based on successful practices already in place in other districts. The first section, "National Diffusion Network--Programs That Work," contains listings of programs that have undergone extensive testing and were approved only if there was evidence that the programs met the stated objectives. In addition, the program directors had to provide evidence that the program would also meet the needs of other groups similar to the one tested. All of the programs listed from the National Diffusion Network are presented with a common format that includes program name, audience (grade level), description, requirements, costs, services, and contact. The following programs are listed: (1) "Conservation for Children;" (2) "PROJECT ECOLogy"; (3) "Informal Science Study" (ISS); (4) "Marine Science Project"; (5) "Starwalk"; (6) "Project Zoo"; (7) "Curriculum Modification through Environmental Studies"; and (8) "Project Kare." The second and third sections list 26 science and 12 science and mathematics programs and practices originating outside of New Jersey. Each listing contains the grade level, description, and contact. The fourth section contains listings of 11 programs offered by community groups and associations in New Jersey. Each listing includes the organization name, project, target population, contact person, and program description. (KR)
