Discipline - Technology/Engineering

Core Idea - Materials, Tools, and Manufacturing

[HS.ETS.2.4] - Explain how manufacturing processes transform material properties to meet a specified purpose or function. Recognize that new materials can be synthesized through chemical and physical processes that are designed to manipulate material properties to meet a desired performance condition. Clarification Statement: Examples of material properties can include resistance to force, density, hardness, and elasticity.

Predecessor Standards:

  • 6.ETS.2.1
    Analyze and compare properties of metals, plastics, wood, and ceramics, including flexibility, ductility, hardness, thermal conductivity, electrical conductivity, and melting point.
  • 8.ETS.2.4
    Use informational text to illustrate that materials maintain their composition under various kinds of physical processing; however, some material properties may change if a process changes the particulate structure of a material. Clarification Statements: Examples of physical processing can include cutting, forming, extruding, and sanding. Examples of changes in material properties can include a non-magnetic iron material becoming magnetic after hammering and a plastic material becoming rigid (less elastic) after heat treatment.

Successor Standards:

No Successor Standards found.

Same Level Standards:

  • WCA.9-10.9
    Draw evidence from informational texts to support analysis, interpretation, reflection, and research. (See grades 9-10 Reading Standard 1 for more on the use of textual evidence.)
  • HS.ETS.2.3
    Compare the costs and benefits of custom versus mass production based on qualities of the desired product, the cost of each unit to produce, and the number of units needed.
