This article outlines how social justice theories, in combination with the concepts of infrastructure access, literacies and community acceptance, can be used to think about equity in out-of-school science learning. The author applies these ideas to out-of-school learning via television, science clubs, and maker spaces, looking at research as well as illustrative examples to see how equity challenges are being addressed in practice. The article argues that out-of-school science learning practices can be understood on a spectrum from weak to strong models of social justice. Thinking about social justice as a spectrum helps us think through what equitable out-of-school science learning practices might involve, both to analyze existing practices and, importantly, to imagine new, more inclusive ones.
