This educator's guide consists of nine sequential activities for younger students, in which they acquire content knowledge and conduct investigations to compare and contrast Mars and Earth. They will begin by examining images of the two planets, learn about the instruments used to make them, and use the knowledge they have gained by examining images of Earth to begin analyzing images of Mars. The students will then test the ideas they have developed in a series of experiments in which they attempt to recreate features that might have been caused by wind, flowing water, or the impact of a falling object. In the final activities, they will use a variety of resources to find out what is known about Mars, hold a science "conference" to share this information, and apply what they have learned about Earth and Mars by selecting a planet as the subject of an imaginary "voyage" to be described by creating comic strips about it.
