Six environmental education simulation games are presented in this manual, developed by Project SESAME G (Susquehanna ESEA Synergetic Activities for Maximal-involvement via Education Games). The simulations are models of social situations which provide an opportunity for social interaction in the classroom, maximize student involvement, and change the roles of both teacher and student. Background information and instructions are given for each game and include an overview of the game, objectives, materials and game components, procedures, win criteria, debriefing, and a space for results of a game tryout. Additional material pertinent to the individual game is appended after each description. The games are titled: Re-Con, Forest Adventure, Camp-O-Rama, Conserv-O, and Specimens and Categories. Suggested uses are for elementary grades (4-8) and high school social studies and general science classes, although many may be adapted for several subject areas. Both role-playing and board games are covered and emphasize decision-making, awareness, identification, classification, and map reading skills. (BL)
