Shaw-IAU Workshops by the OAE

We present a hands-on classroom activity simulating galaxy photometry with RGB LEDs (blue=starburst, red=quiescent, white=star-forming) behind diffusers, using consumer cameras and colour filters. Students capture filtered images, analyse them in ImageJ, measure colour indices, and create false-colour composites. By comparing their results to models, they learn how astronomers use colours to determine galaxy types and star formation histories. This approach demonstrates photometric techniques while connecting LED measurements to real galaxy evolution concepts. The activity bridges theory and observation, with natural extensions to professional datasets like SDSS. Designed for secondary schools, it makes authentic astronomy accessible through everyday materials and open-source tools.

About Jana Bogdanoska

Jana Bogdanoska is an assistant professor of astronomy and physics education at the Institute of Physics in Skopje, North Macedonia. She holds a PhD in astrophysics, with research focused on galaxy evolution, chemical enrichment, and dust in the early Universe. In recent years, her work has expanded to include teacher education, low-cost experimental methods, and the integration of authentic data and AI tools in physics and astronomy classrooms. She is passionate about making astronomy accessible, conceptually rich, and inquiry-driven for both students and teachers at all levels.
