In this research-based unit, students learn a great deal about the Earth, gravity, and astronomy. Sections focus on the shape of the Earth and gravity; moon phases and eclipses; and the stars. Students ponder questions such as: If the Earth is a ball, why does it look flat? Why does the moon change its shape? How can I find constellations and tell time by the stars? Activities include observing and recording changes in the sky and creating models to explain observations. A challenging questionnaire on the Earth’s shape and gravity can be used as a pre- and post assessment tool. This wide-ranging interdisciplinary unit also connects to world cultures through its exploration of myths about the rising and setting of the sun.
