[7.ETS.3.4] - Show how the components of a structural system work together to serve a structural function. Provide examples of physical structures and relate their design to their intended use. Clarification Statements: Examples of components of a structural system could include foundation, decking, wall, and roofing. Explanations of function should include identification of live vs. dead loads and forces of tension, torsion, compression, and shear. Examples of uses include carrying loads and forces across a span (such as a bridge), providing livable space (such as a house or office building), and providing specific environmental conditions (such as a greenhouse or cold storage). State Assessment Boundary: Calculations of magnitude or direction of loads or forces are not expected in state assessment.

Predecessor Standards:

  • 5.ETS.3.2
    Use sketches or drawings to show how each part of a product or device relates to other parts in the product or device.*

Successor Standards:

  • HS.ETS.3.3
    Explain the importance of considering both live loads and dead loads when constructing structures. Calculate the resultant force(s) for a combination of live loads and dead loads for various situations. Clarification Statements: Examples of structures can include buildings, decks, and bridges. Examples of loads and forces include live load, dead load, total load, tension, sheer, compression, and torsion.

Same Level Standards:

  • WCA.6-8.7
    Conduct short as well as more sustained research projects to answer a question (including a self-generated question), drawing on several sources and generating additional related, focused questions that allow for multiple avenues of exploration.
  • 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.
  • 7.ETS.3.3
    Research and communicate information about how transportation systems are designed to move people and goods using a variety of vehicles and devices. Identify and describe subsystems of a transportation vehicle, including structural, propulsion, guidance, suspension, and control subsystems. Clarification Statements: Examples of design elements include vehicle shape to maximize cargo or passenger capacity, terminals, travel lanes, and communications/controls. Examples of vehicles can include a car, sailboat, and small airplane.
  • 7.ETS.3.5
    Use the concept of systems engineering to model inputs, processes, outputs, and feedback among components of a transportation, structural, or communication system.
