We investigated how community ethnography as a pedagogy approach to STEM-rich making supported youth makers from two low-income urban communities engaged in sustained STEM-rich making towards making a difference in their communities. Data is drawn from two-year long ethnographic data across two community-based, youth making programs. We highlight two cases. Case #1 focuses on one African American girl's making endeavors across one school year. Case #2 looks at how two youth engaged in critical sense-making with regards to the currently available how-to making resources they could locate online. We discuss how these pedagogical moves supported the youth in making towards a more just future in ways that addressed intersecting scales of injustice.
