There is more to the solar system than the typical study of the sun and planets. Launch a study of asteroids, meteoroids, and comets by watching the video The Story of the Solar System, available for purchase through this resource on the Discovery Education website. Then break the class into small groups to research celestial objects. Group members create posters that include illustrations and interesting facts, and prepare a presentation for the class about their object. This plan contains some interesting ideas that may be useful even without the paid video.
