In this paper, results from a 2-year informal science education study are presented. Children (aged 8-12) in this study participated in multi-aged groups to learn science within the context of paleontology and climate change. The goals of the project were to increase science content knowledge among underrepresented minority students and to enhance their interest in science. Providing urban students of color with opportunities to learn science may promote social justice and science as a civil right. Students in this study demonstrated science content knowledge and academic brilliance as they engaged in environmental science tasks. Results of paired t tests revealed science content knowledge increased significantly in Phase 1 (Saturday academy) of the study and on two of three content tests in Phase 2 (summer camp). Qualitative data revealed the depth of student learning and that student interest in science was generally positive. We conclude the program was moderately successful in terms of its goals and provided lessons learned in terms of engaging in equitable science teaching. This study adds to the extant literature on underrepresented students' content knowledge and interest in science while participating in place-based, informal science education focused on paleontology and climate change.
