Students begin with a brief exploration of biomes. Then, as a class, the students choose a specific biome and examine a food web within it. This will lead to a discussion about predator/prey relationships. Students will develop an understanding of the differences within the digestive systems of different organisms and how the foods eaten correspond to the digestive system and biome of each organism. Finally, we examine the digestive system of humans in detail. The culminating event is a pop-up book about human digestion.

Reviewer Comments:

In this comprehensive 19 day unit, middle school students (grades 6 – 8) will use a variety of research activities to investigate biomes, food and digestion among various animals and across cultures. The unit culminates in a student-constructed pop-up book containing information on “the roles of biomes, food webs, culture, food pyramids and digestive systems.” The research is accomplished jigsaw style and there is ample time for student sharing. This well-planned resource includes references to national (USA) standards, a rationale, a detailed procedure, suggested websites and rubric assessments throughout. The final product is quite intensive, and some students may need help breaking it down into small, specific steps, although the preceding activities may serve this purpose. This resource also includes a nice end-of-unit reflection. This unit requires minimal set-up and can be immediately in the classroom.
