The ubiquitous use of social media by children offers a unique opportunity to view diverse funds of knowledge that may otherwise be overlooked. To leverage this insight, we have coupled the iterative development of our community focused, Science Everywhere life-relevant science learning program together with an integrated social media app to engage learners aged 6-16 in science with parents, teachers, and mentors throughout their community. We found that learners' scientific funds of knowledge were often not evident in their posts alone; rather, they emerged through our triangulation of posts, interviews with youth and their parents, and observations of their learning experiences in our life-relevant science education program. Our findings suggest that leveraging new social media features to support contextual information, scientific scaffolds and creative expression may make children's implicit and more unconventional scientific funds of knowledge more apparent. Additionally, social media sharing in conjunction with other practices, such as discussing posts with learners and encouraging non-science posts, can uncover the rich contexts of children's social media sharing, which can illuminate their scientific thinking.
