In this inquiry investigation, students learn that while the Sun appears to move around the Earth, in fact it is the Earth spinning around on its axis while the Sun remains stationary. Materials suggested for this activity include an easel or wipe board and markers, pencils, journals, crayons, and adhesive dots or bingo markers. This is the second of 10 inquiry investigations in Threads of Inquiry: Observing the World Around Us. Each lesson includes teacher background information, a narrative that models and describes the inquiry process applied in the lesson, and a hands-on inquiry investigation. Literacy extensions and a non-linguistic pre- and post-assessment are also included.
