[PS4] Waves and Their Applications in Technologies for Information Transfer

SCI-04.PS4.03 Construct a code to convey information by researching past and present methods of transmitting information.

Clarification Statement: Examples of past methods could include a string between two cans, Morse code, rotary dial telephones. Examples of current methods include fiber optics, digitized signals, wireless communication, blue tooth, and using for exploration of computer coding patterns.
Disciplinary Core Ideas
Digitized information can be transmitted over long distances without significant degradation. High-tech devices, such as computers or cell phones, can receive and decode information- convert it from digitized form to voice-and vice versa.
Optimizing the Design Solution Different solutions need to be tested in order to determine which of them best solves the problem, given the criteria and the constraints. (secondary)
