Let There Be Night

To quantify how much of the night sky has been lost to light pollution, students in grades 3-8 compare their backyard view of Orion to six star charts of the constellation with varying limiting magnitudes. Using thousands of observations from across the local community, teams of students from individual schools plot the collective results by constructing a 3D model out of LEGO blocks. Beforehand, all teachers integrate some aspect of the topic in their regular classroom instruction. The website offers supporting lessons, resources, and ideas for teachers and families alike.
