Description
Remote satellite images of the Earth are used to distinguish impact craters from other landforms.

Objectives
Students will:
• Describe the effects of extraterrestrial objects upon the Earth's topography, atmosphere and living organisms.
• Describe the role of satellite technology in helping scientists to identify evidence of impact events.
• Describe why and how science is an ongoing process of discovery.

Lesson Activities and Sequence

  1. Finding Impact Craters
    This activity will guide students through discussions regarding known impacts that have occurred on the Earth and the possible outcomes that have resulted.

    Working in teams of three to five, students will then evaluate satellite images of the Earth to determine the traits associated with impact craters in different regions of the world.

    The activity description contains six steps with the first three steps providing background, which may or may not be required for every group in the upper grade levels.
