After completing the seven lessons in this unit students will have learned how scientists find locations on a globe and use maps to find locations on Earth's surface. They will be able to identify and use the different kinds of maps used by scientists. They will discover how scientists use a compass to record the positions of landmarks on the horizon and how ancient scientists used a sundial to tell time. They will draw contour maps to describe elevations above sea level and use their map to construct a three-dimensional model of Earth's surface. STUDENT WORKSHEETS, an EDUCATOR GUIDE, and the UNIT TEST for assessing student performance after completing this unit are included.
