![]() ![]() ![]() Students will use their models to expand their understanding by arguing from evidence why their models are correct and adding the scientific names that scientists use for the different phases in the pattern. ![]() They will connect this information to their previous understanding that the cyclical pattern takes approximately 28 days to repeat. They will discover that the lunar patterns recycle after a full rotation around the earth. Students will explain their understanding of the lunar patterns by creating a physical representation that simulates what they have observed. Students will then explore by gathering more information from Universe Sandbox to reason about the cause of the patterns by developing their models of the Sun-Earth-Moon system, leading them to question why the pattern recycles approximately every 28 days. This will lead them to question the cause of the pattern. Through observation, students will argue from evidence to discover that the moon changes in a cyclical pattern that takes approximately 28 days. To begin our storyline, students are presented with the phenomena, does the moon change shape in a pattern? To obtain information, students will engage in an observation of the moon’s changing appearance. This standard suggests developing physical, graphical, and conceptual models. SEEd Standard 6.1.1 asks students to develop and use a model of the Sun-Earth-Moon system to describe the cyclic patterns of lunar phases, eclipses of the Sun and Moon, and seasons. ![]()
