This article portrays how citizen science (CS) projects can be integrated into elementary classrooms to enhance students’ sensemaking skills and connect to real-world science problems. For the last several years, we have been involved in a study, Teacher Learning for Effective School-Based Citizen Science (TL4CS), that developed materials for elementary school teachers to engage their students in data collection, analysis, and interpretation for two existing CS projects: Community Collaborative Rain, Hail, and Snow Network (CoCoRaHS) and the Lost Ladybug Project (LLP). After piloting the TL4CS materials for two years, two teachers, Penny and Amy, share the ways they used the materials to create rich sensemaking experiences for their students. Penny used our TL4CS CoCoRaHS materials to make connections between their daily precipitation data and local weather phenomena, patterns in ecosystems, and student-created graphs. Amy used our TL4CS LLP materials to explore students’ questions about human impact on animals’ habitats and discover the importance of biodiversity in ecosystems. As demonstrated by Penny’s and Amy’s stories, the TL4CS materials can transform mere data collection for CS projects into opportunities for real-world connections and sensemaking in science classrooms.
