Description:

This activity focuses on the question, What do active galaxies look like when viewed from different distances? Students work in small groups to learn about the small angle formula, construct a template, and use it to correctly measure the angular size of a person. Students then use the Active Galaxies Poster to measure the angular size of a galaxy. Materials are commonly available or inexpensive items, e.g., scissors, cardboard, construction paper, calculator, protractor, meter stick or measuring tape). Includes background information, glossary, essential questions, extension activities, transfer activities, adaptations for visually-impaired students, and an answer key. This is activity 2 of 3 in the Active Galaxies Educators Guide.
