Using Population Education curriculum: 1. Participants will increase their understanding of basic human ecological concepts and best practices for introducing these concepts in their K-5 classrooms in an age-appropriate way. 2. Participants will come away with a rationale for why environmental education is a priority at all grade levels, how it is supported by research, and how environmental education is truly interdisciplinary, combining numeracy, literacy, science and social studies. 3. Participants will be able to design interdisciplinary, interactive lesson plans using Population Education curriculum on environmental themes that work for a variety of learning styles in a differentiated classroom.
