An environment appropriate for activity-oriented science is one that contains sufficient work space, equipment, and materials for students to practice and master the essential elements. This publication was developed to aid Texas school administrators, teachers, and architects to upgrade existing science facilities or plan new ones for kindergarten to grade 12. Chapter titles are as follows: (1) Overview of the Science Program; (2) Elementary School Science Facilities; (3) Middle Junior High School Facilities; (4) High School Science Facilities; (5) Computers in the Science Laboratory; and (6) Sample Floor Plans for Science Facilities. The chapters give details on science equipment needed, safety features that are necessary, and characteristics of science instruction. Appendix A,"Conditions of Instruction," is a National Science Teachers Association document pertaining to recommended work conditions for science teachers. Appendix B outlines state laws and regulations that apply to safety in science education and lists addresses of organizations that can help improve the safety of the classroom. The last appendix contains a laboratory safety checklist for science teachers. (PR)
