This self-playing musical power point is the ideal introduction to any science class. Students often wonder where we are in the universe. This song gives planet Earth's cosmic address (planet, solar system, galaxy, cluster, supercluster) in the universe. No matter what type of science I'm teaching (earth science, physical science, etc.) I always like to start off the year with this to help put everything in perspective. Then we revisit the song periodically throughout the year to keep it fresh in our minds. A super fun way to get your class excited about science.
