In this unit, students learn about the sky. They learn why we have day and night, why the sun is important, and why the moon doesnt always look the same. Students also investigate the stars and planets. All the lessons are literature-based with hands-on activities and experiments. *Since it takes 28/29 days to fully observe the phases of the moon, send home the calendar observation sheet two weeks before you start the unit. See unit attached files to find the observation sheet.
