You will be able to use the lesson plans on this site all year long, whether you teach kindergarten or high school. The elementary topics deal with cycles--water cycle, life cycle, plate tectonic cycle, and universe cycle. You can download workbook pages that correspond with the lessons. Several of the lesson plans for the secondary topics are still under construction, but what is available is certainly worthwhile. The lessons on math integration in Physical Science are especially interesting. The sections contain reading material (complete with descriptive graphics), classroom labs, quizzes, vocabulary lists, interactive slides, and teacher outlines. Some resources require Java.
