This 190 slide PowerPoint presentation includes general information on the eight planets (and dwarf planets), a ton of pictures on each planet (as many as I could fit), and a planet identification quiz.
Main points include: solar system (what is it?), astronomical units (AU), why the sun and planets are round, our 8 planets, terrestrial planets (Mercury, Venus, Earth, Mars), the gas giants (Jupiter, Saturn, Uranus, Neptune), Pluto and dwarf planets, and how we see planets by reflected sunlight
