Learning goals of lesson segments Introduction students should be able to list ways people have viewed the Earth at different times in history. describe how the Earth appeared to astronauts in space and on the moon. describe what they might use to look at the Earth today. Landsat Information students should be able to explain how Landsat travels around the Earth explain why this type of path is more useful than others describe (approximately) the largest and smallest areas that Landsat can image. Geographical Features students should be able to use several skills and facts about Landsat to make inferences about Landsat images. These might include, but are not limited to: determining distance scales using the image size and size of the area depicted using distance scales to determine types of features from the imaged size; is it a mountain or a molehill? distinguishing natural features from man made ones distinguishing topographic features from surface variations; is it a valley or a shadow? interpreting the significance of color; are the colors literal, as in a photograph, or do them have other meanings?
