This thesis adds to the empirical research foundation of informal science education through an investigation of a museum-based astronomy internship for high school students, in the domains of attitudes toward science, knowledge of science, and participatory science learning. Results are presented as three studies, all using a qualitative methodology and including the methods of semi-structured interview, reflective journal, direct observation, audio recording, and artifact collection.

During the apprenticeship, youth develop knowledge and skills to create informal science education projects: through these projects they demonstrate their understanding of astronomy and use their communication skills to connect to
