Great overview of this topic. Starts with meteors,comets causing meteor showers, asteroids and their distribution in the solar system. Has great images. 94 slides. High School level but with some changes could be made college level for intro to astronomy level. There are lots of slides to choose from if you want to totally chnage this around or add your on stuff.

I have taught 5 years at a public school - 8th grade Physical Science and 9th grade Earth Science. I have a MSEd from Binghamton University. I am currently teaching and coordinating programs at the Kopernik Observatory in Vestal, New York. See www.kopernik.org All my labs, tests, and worksheets have been actually used in the classroom.
