RESEARCH ON THE ELECTROMAGNETIC SPECTRUM

Summary: This group project (3-4 people per group) oral presentation each individual turns in a written report. All group members will participate in the oral presentation.

Point Value: 100 points for written report; 30 points for oral presentation. (Oral presentation must be given to get points for written portion.)

Written Report: Turned in immediately before the presentation. Each person writes only about their area of responsibility. The report must be neatly hand-written, and one page long.

Oral Presentation: Presentations will begin on 3/22. The presentation should be 2-4 minutes long. Only note cards and visual aids can be used. Present in order of “Responsibilities”

Responsibilities: 1) History Describe the historical background of this type of electromagnetic radiation. History of discovery Growth of knowledge Historical usages Etc.

Responsibilities: 2) Sources Describe how this type of EMW is produced. Natural Sources Man-made sources How do these sources work to produce this radiation?

Responsibilities: 3) Uses Describe how people use this type of electromagnetic radiation. This can include scientific, military, commercial, personal, and other uses.

Responsibilities: Effects on Human Body: Describe how this type of electromagnetic radiation affects our body. Does it harm us? Can it help us? Can we sense it with our skin? In the case of radio waves, discuss the current thinking of experts on the effect of radio waves on our body.
