In this chapter, students will easily recognize the learning they do related to the disciplinary core ideas, specifically that shadows made by the Sun can be observed, described, predicted, and explained with models to reveal patterns of the Sun’s apparent motion. The chapter also integrates the science practices and crosscutting concepts as students learn what we know about the apparent motion of the Sun throughout the day. A materials list, teacher background information, and outcomes are provided.
