Learning Objectives

Students will:

·        Understand the difference between satellite radio and conventional radio stations, and how the use of a tuner is essential to the latter

·        Describe the changes that both the radio and television have gone through, from their invention to now, and identify those changes through observations of advertisements

·        Distinguish differences in writing for radio vs. writing for television by creating their own radio play

Next Generation Science Standards

·        1-PS4-4. Use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance.*

o  Clarification Statement: Examples of devices could include a light source to send signals, paper cup and string “telephones,” and a pattern of drum beats.

o  Assessment Boundary: Assessment does not include technological details for how communication devices work

·        MS-PS4-3. Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.

o  Clarification Statement: Emphasis is on a basic understanding that waves can be used for communication purposes. Examples could include using fiber optic cable to transmit light pulses, radio wave pulses in Wi-Fi devices, and conversion of stored binary patterns to make sound or text on a computer screen.

o  Assessment Boundary: Assessment does not include binary counting. Assessment does not include the specific mechanism of any given device
