This document outlines a didactic unit on ecosystems for a 2nd grade science class. The unit objectives are to identify the principal elements of natural environments by analyzing their organization, characteristics, and interactions. Students will identify animal habitats, create their own ecosystem, and learn vocabulary. Lessons will include exploring aquatic and terrestrial ecosystems and their changes throughout the year. Students will work in groups to create "grassland" and "marine" classroom ecosystems. The unit emphasizes active, communicative, participative and cooperative learning. Assessment will include observation, rubrics, and the quality of students' care for and presentation of their classroom ecosystems.
