The National Science Education Standards (NSES) state that students in grades K—4 are expected to understand that astronomical objects in the sky, including the Sun, Moon, and stars—have properties, locations, and patterns of movement that can be observed and described. They further suggest using an inquiry-based approach to teach these science concepts. However, there are several challenges in teaching space science concepts through actual observation. To address these concerns, the authors share two inquiry-based astronomy lessons for young children using selected trade books and real sky images via computer.
