in a Wave?
|You have a job working for the FCC (Federal Communications
Commission) regulating the
wave frequencies used by wireless businesses and radio stations.
A new telecommunications
firm wants to purchase the exclusive right to use a specific
frequency for wireless telephones. You must determine what wave
frequency you would assign the new company.
In previous science courses you have learned that color appears
as visible waves of light
in the form of a rainbow (ie., orange, yellow, green, blue, indigo,
and violet). This is only
one section of the electromagnetic spectrum. Other sections of
the spectrum include
gamma rays and microwaves.
For background information about the FCC and the spectrum see
the article below.
Task and Product
Working in small groups, you will use the Understanding
Electromagnetic Spectrum activity
sheet to complete the basic research. You will then use Inspiration
or Microsoft Word to
create a graphic organizer containing definitions and examples
of waves in the electromagnetic spectrum highlighting the wave
section for the new telecommunications company. The final product
will be to complete a BCR addressing the essential question below.
Use the pre-reading vocabulary handout to prepare for the research
Pre- Reading Vocabulary
Use the following handouts for library research.
Understanding the Electromagnetic
Spectrum and Graphic Organizer
Use the following handout for your final
Final Product - Brief Constructed
You may also consider using VoiceThread or making a Podcast or Wiki webpage as an alterntive to a BCR.
Teacher note: To facilitate the collaborative nature of this project, consider creating a project-based wiki or using another collaborative Web 2.0 tool (VoiceThread, MindMeister, Groupsite.com, etc.) to use as a workspace.

As an extension students can examine how spectroscopy is
used to study
stars and planets and determine spectral fingerprints.
