Core Idea - Waves and Their Applications in Technologies for Information Transfer

[4.PS.4.2] - Develop a model to describe that light must reflect off an object and enter the eye for the object to be seen. State Assessment Boundary: Specific colors reflected and seen, the cellular mechanisms of vision, angles of incidence and reflection, or how the retina works are not expected in state assessment.

Resources:

Predecessor Standards:

  • 1.PS.4.3
    Conduct an investigation to determine the effect of placing materials that allow light to pass through them, allow only some light through them, block all the light, or redirect light when put in the path of a beam of light. Clarification Statements: Effects can include some or all light passing through, creation of a shadow, and redirecting light; Quantitative measures are not expected.

Successor Standards:

  • 6.PS.4.2
    Use diagrams and other models to show that both light rays and mechanical waves are reflected, absorbed, or transmitted through various materials. Clarification Statements: Materials may include solids, liquids, and gases. Mechanical waves (including sound) need a material (medium) through which they are transmitted. Examples of models could include drawings, simulations, and written descriptions. State Assessment Boundary: State assessment will be limited to qualitative applications.

Same Level Standards:

  • RI.4.3
    Explain events, procedures, ideas, or concepts in a historical, scientific, mathematical, or technical text, including what happened and why, based on specific information in the text.
  • W.4.8
    Recall relevant information from experiences or gather relevant information from print and digital sources; take notes and categorize information, and provide a list of sources.
  • 4.MD.C.5
    Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
  • 4.G.A.3
    Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
