MS-PS4-3 | Application of Waves

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.

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 wifi devices, and conversion of stored binary patterns to make sound or text on a computer screen.

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

Performance Level Descriptions

PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.

Level 4Level 3Level 2Level 1

Integrate multiple pieces of 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 and how these digitized signals are used for communication purposes.

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.

Identify one piece of qualitative evidence and one piece of technical information that supports the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.

Identify one piece of qualitative evidence or one piece of technical information that supports the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.

NGSS Dimensions

Performance expectation MS-PS4-3 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices

Obtaining, Evaluating, and Communicating Information
- Integrate qualitative scientific and technical information in written text with that contained in media and visual displays to clarify claims and findings.

Disciplinary Core Ideas

PS4.C: Information Technologies and Instrumentation
- Digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information.

Crosscutting Concepts

Structure and Function
- Structures can be designed to serve particular functions by taking into account properties of different materials, and how materials can be shaped and used.

Connections to Other Standards
