Learners will investigate how much you can learn about something just by looking at it. In Activity 1, students study aerial photographs to identify geologic features, determine how they differ from one another, and examine the processes involved in their formation. In Activity 2, students investigate how remote observations of a planetary surface can be used to create geologic maps. By the end of the lesson, students will understand how data gathered by spacecraft can not only be used to investigate the properties of an object, but also how it was formed, how it has evolved over time, and how it is connected to other objects nearby. Note: The MESSENGER mission to Mercury that is mentioned in this lesson ended operations April 30, 2015. For the latest information about MESSENGER and NASA's solar system missions see the links under Related & Supplemental Resources (right side of this page).
