Oreo eclipse

Safe Solar Viewing (Grades 3-6 Only)

Each of your students will love tracking the progress of the solar eclipse with an Oreo Cookie!  Just twist it apart and use it to model current progress of the eclipse as it occurs.  Making the cookie connection will help students understand how the sun and moon interact to make the crescent shapes that their pin hole projectors show. Eat it after the eclipse :)
