Core Idea - Waves and Their Applications in Technologies for Information Transfer
[6.PS.4.3] - Present qualitative scientific and technical information to support the claim that digitized signals (sent as wave pulses representing 0s and 1s) can be used to encode and transmit information. State Assessment Boundary: Binary counting or the specific mechanism of any given device are not expected in state assessment.
[RCA-ST.6-8.1] -
Cite specific textual evidence to support analysis of science and technical texts, quoting or paraphrasing as appropriate. (See grades 6-8 Writing Standard 8 for more on quoting and paraphrasing.)
[WCA.6-8.9] -
Draw evidence from informational texts to support analysis, interpretation, reflection, and research. (See grades 6-8 Reading Standard 1 for more on the use of textual evidence.)
[4.PS.4.1] -
Develop a model of a simple mechanical wave (including sound) to communicate that waves (a) are regular patterns of motion along which energy travels and (b) can cause objects to move. Clarification Statement: Examples of models could include diagrams, analogies, and physical models.
State Assessment Boundary: Interference effects, electromagnetic waves, or non-periodic waves are not expected in state assessment.
[4.PS.4.3] -
Develop and compare multiple ways to transfer information through encoding, sending, receiving, and decoding a pattern.*
Clarification Statement: Examples of solutions could include drums sending coded information through sound waves, using a grid of 1s and 0s representing black and white to send information about a picture, and using Morse code to send text.
[7.ETS.3.1] -
Explain the function of a communication system and the role of its components, including a source, encoder, transmitter, receiver, decoder, and storage.
[HS.PHY.4.5] -
Communicate technical information about how some technological devices use the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.* Clarification Statements: Emphasis is on qualitative information and descriptions. Examples of technological devices could include solar cells capturing light and converting it to electricity, medical imaging, and communications technology. Examples of principles of wave behavior include resonance, photoelectric effect, and constructive and destructive interference.
State Assessment Boundary: Band theory is not expected in state assessment.
[HS.ETS.3.2] -
Use a model to explain how information transmitted via digital and analog signals travels through the following media: electrical wire, optical fiber, air, and space. Analyze a communication problem and determine the best mode of delivery for the communication(s).
