Similar features exist on the surfaces of Earth and Mars. This investigation includes satellite images of five Earth features and five Martian features, none of which are labeled. Students must compare and contrast those images to produce five... (View More)

This article discusses how the Multi-angle Imaging SpectroRadiometer (MISR) instrument found on the Terra satellite is used to understand how particles in the atmosphere interact with sunlight and how particle pollution affects Earth's climate.... (View More)

In this activity, students compare and contrast the visual perspectives that result when viewing objects from different distances. In part one of this lesson, students view simple shapes from varying distances and record their observations. Then, in... (View More)

Using both literature (a book featuring a path, such as Little Red Riding Hood) and satellite images, students will identify paths, observe and analyze them from different altitudes, and distinguish natural paths from those made by humans. Students... (View More)

Searching the six satellite images of Mars provided in this investigation, students identify and locate areas that possibly sustained life in the past, might now sustain life, or could in the future. The URL opens to the investigation directory,... (View More)

Students understand how satellites are placed in orbit by launching marbles into space, using two plastic rulers and clay. They describe the forces that determine the trajectory of flight. The resource is part of the teacher's guide accompanying the... (View More)
