Building Perspectives with Active Galaxies

(View Complete Item Description)

In this activity, students build a model of an active galaxy. From this, they will learn about the geometry of the components of an active galaxy and develop an understanding that different viewing angles can lead to dramatically different interpretations of a galaxy's appearance. The activity includes background information, glossary, essential questions, extension activities, transfer activities, adaptations for visually-impaired students, and an answer key. Additional materials needed to do this activity include a compass. This is activity one of three in the Active Galaxies education unit.

Zooming In on Active Galaxies

(View Complete Item 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.
