The first of thirteen units suggested for an environmental education curriculum is presented in this teacher's guide. The collection of units for grades K-12 was written in response to a mandate from the Minnesota State Legislature through a bill making provisions for developing and implementing a state-wide environmental education program. The units are experimental in nature and are not oriented as to subject matter or academic discipline. The kindergarten unit, "Recognizing Associations", strives to make children become aware of the associations between a symbol and an event in order to predict an appropriate outcome. To do this the skills of reasoning and observation are stressed, with experimentation used only to help pupils realize it is necessary to pay close attention to procedure in order to make valid predictions. The activities are designed to provide experiences in comparing and contrasting, duplicating structures, and predicting outcomes. A list of materials needed precedes each activity. Although written for a specific grade, the unit can be adapted for any level or situation. (BL)
