NGSS guidance indicates that a life science curriculum's unit on evolution must include the concepts of geologic ages, endangered species, Anthropocene extinction, and biodiversity. Enrichment lessons and labs deepen student understanding of key standards. This lesson enriches students by presenting a real-world opportunity for species conservation. First, instructors ensure a common understanding of background knowledge among students. Second, levels of species endangerment are introduced and students participate in a “willingness to pay” lab involving a philatelic-based fund to protect endangered species. Third, predicted student donation amounts are compared to actual costs needed to conserve and manage species in the wild. Finally, summative reports communicate actual conservation needs by comparing and contrasting two endangered species.
