2 2. Information Sources There are three major types of galaxy forms. Using the given sources, investigate the types and how they evolved. http://amazing- space.stsci.edu/resources/expl orations/galaxies-galore/ http://www.kidsastronomy.com/g alaxys.html http://www.windows2universe.org /the_universe/Galaxy.html Note: Image Copyright NASA, ESA, and the Hubble Heritage (STScI/AURA)-ESA/Hubble CollaborationNASAESA Hubble HeritageSTScIAURAESA 1111 2222 3333 6666 5555 4444 Next These materials are © 2011 Lauren Havelka, Towson University, all rights reserved, unless other wise stated.

3 3. The Student Activity As you look through the links, think about the different types of galaxies and what attributes they have. Think about the ways that each galaxy type is different. What types of stars do they have? How old are the galaxies? What caused each galaxy to have the shape that it does? Using the graphic to the right organize the types of galaxies and their characteristics.

4 4. The Assessment Activity So what type of galaxy is the Andromeda? Review photographs and a stats sheet of Andromeda, and decide which type of galaxy Andromeda classifies as. Write a short paragraph using at least 3 facts from the sheet and from your investigations to support your conclusion.
