CMEs: Satellites in Peril

http://seal.nascom.nasa.gov/gallery/LASCO/las024.gif

Abstract:
In this investigation, students will visit various sites to learn about the effects a coronal mass ejection has on satellites in orbit above the Earth’s atmosphere. Coronal Mass Ejections (CMEs) are massive (10e14 to 10e17 kilograms) clouds of plasma that are ejected from the Sun’s outer atmosphere, or corona. The corona is the gaseous region above the surface that extends millions of miles into space.

Suggestions are provided so that teachers will be able to do the investigations using equipment they have available.

Outcome:
• Students will visit Internet sites to gain information and understanding to learn why coronal mass ejections occur and the impact they have on satellites above the Earth’s atmosphere.

Suggested Grade Level & Duration:
Grades 5-8; 9-12; 3 to 4 fifty-minute periods.

Materials:
Internet ready PC
