Are you teaching a unit on stars? This 38 slide PowerPoint 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 are filled in by clicking. I have students fill out the student note taking guide that corresponds with the PowerPoint while viewing that may be purchased separately.
