The document outlines a comprehensive integrated unit for teaching third graders about three biomes: wetlands, temperate forests, and mountains, incorporating science, social studies, reading, writing, and visual arts. It includes detailed learning goals, vocabulary, assessment methods, and modifications for diverse learners, culminating in a 'museum' project where students showcase their knowledge and artwork. The unit is designed to promote hands-on learning and critical thinking as students explore how biomes interact with living organisms and are influenced by human actions.
