Are you teaching a unit on stars? This worksheet corresponds with a 38 slide PowerPoint which describes constellations and gives opportunities for students to identify several. It continues by relating information about binary, triple, and quadruple star systems. Next, three types of galaxies are shown and described: Spiral galaxies, elliptical galaxies, and irregular galaxies. Finally, star clusters, global clusters, and quasars are presented. The format has blanks that students fill in with the PowerPoint.
