The United States is currently experiencing its most severe measles outbreak in decades, driven in part by parents' belief that vaccines cause autism. That harmful misinformation is contrary to scientific evidence (DeStefano et al. 2013). The CEO of the American Association for the Advancement of Science, the world's largest multidisciplinary scientific society, is concerned that fewer and fewer members of the public understand "the very idea that science is a special way for separating truth from falsehood" (Holt 2017). The proliferation of misinformation has become so serious that, as an editorial in "The Science Teacher" noted, "evidence-based reasoning seems under assault" (Metz 2017). In response, the authors have developed and tested a free, research-based, one-week curriculum unit for use in grades 6-12. In the sections presented in this article, the authors expand upon the reasons for creating the unit, describe the materials, discuss the pilot test conducted in six schools, and then indicate how the unit aligns with national education standards. This unit is aligned with both the "Common Core State Standards" and the "Next Generation Science Standards."
