Galaxy Graphic Organizers
Your assignment is, using the tables, complete the two graphic organizers. Use the
Galaxy Facts to complete the Comparison of Spiral, Elliptical, and Irregular Galaxies.
Use the Warped Galaxy & Whirlpool Galaxy Facts to complete the Venn Diagram. Don’t
forget – when completing a Venn Diagram, facts common to only the Warped Galaxy go
in the Warped Galaxy circle. Facts common to only the Whirlpool Galaxy go in the
Whirlpool Galaxy circle. Common facts go in the center where the two circles intersect.
