Learners will explore the difference between natural and artificial satellites and use images taken by robotic spacecraft and telescopes to gain an understanding of the Earth's place in space. Requires the books "Me on the Map" by Joan Sweeney and... (View More)

In this learning activity, students create a 3D model of part of their local landscape, then make a series of observations from different directions. Using the bird's eye view, they translate the 3D model into a 2D map with a scale and key, and... (View More)

This learning activity familiarizes students with the concept of modeling as it is related to remote sensing and to the process of digitizing images. Students create a digitized image of a map that they have created, and through this activity... (View More)

In this online, interactive module, students learn how enhanced Earth remote-sensing capabilities are used by dozens of satellites that are continuously collecting data from multiple vantage points. This allows scientists from different countries to... (View More)

This activity helps students understand the connections between remote-sensing technology, computer imagery and land cover assessment, and models how a satellite sensor communicates information to a computer. Digital information from a map created... (View More)

In this fieldwork activity, students learn that when setting up a research design a system's boundaries are based on the question(s) a scientist wants to answer. Students ground truth, or validate, a pixel within a homogeneous area of a satellite... (View More)

In this activity, students consider the sudden release of a tremendous amount of kinetic energy when an extraterrestrial object strikes the Earth. In small groups, they study satellite images that show possible evidence of impact events. To... (View More)

This is a activity about how reaction wheels affect spacecraft orientation (attitude). Learners will observe Newton's Third Law (action-reaction) in the changes caused by a reaction wheel acting upon a spacecraft suspended from a support wire and in... (View More)

Worldwide patterns and sources of aerosols are analyzed and evaluated for potential hazards to aircraft safety. Using aerosol index maps created from data gathered by the TOMS instrument, student groups will analyze and compare aerosol data from... (View More)
