This study explores Multimodal Community Journals (MCJs) as a collaborative visual storytelling, research, and community tool that empowers Black and Latina girls while fostering their engagement with Science, Technology, Engineering, Arts, and Mathematics (STEAM). Analyzing the multimodal texts created by the "Dig-A-Girls" and their community--integrating writing, drawing, and photography--this research examines how they express their identities, experiences, and perspectives in relation to STEAM. The MCJ served as a platform for participants to construct meaningful narratives, assert agency, challenge dominant narratives, and advocate for social justice. By centering multimodal pedagogies in STEAM education, this study highlights the importance of prioritizing the voices and lived experiences of underrepresented students. Ultimately, MCJs cultivate authentic self-expression, collaboration, and critical engagement, offering a transformative approach to STEAM learning.
