Elementary students find it difficult to connect the apparent motion of objects in the sky with how celestial objects actually move in the solar system. As a university astronomy education researcher, the author has been investigating methods to help children learn astronomy through workshops and summer camps at science museums and planetariums. In this article, she shares an investigation of the seasonal constellations that uses embodied learning strategies to help students with this complex spatial thinking. Students make observations of constellations using a computer program called "Stellarium," develop evidence-based claims that describe the pattern of change in the seasonal constellations, and make sense of their observations by modeling their own bodies as the Earth while it orbits the Sun.
