Item Type(s):
This benchmark may be assessed using:
MC
item(s)
Also Assesses - Clarification :
Students will describe and/or explain that waves move at different speeds through different materials.
Students will explain that light waves can be reflected, refracted, and/or absorbed. - Content Limits :
Items may assess the general relative order of wave speed in different phases but will not assess the motion of the particles in the substance.
Items may assess pitch as related to frequency.
Items will not assess color as related to wavelength.
Items will not assess electromagnetic waves traveling in a vacuum.
Items will not require calculations of wave speed through different materials.
Items may address water waves but not in the context of water waves at the beach.
Items will not assess the interaction of multiple waves. - Stimulus Attributes :
None specified - Response Attributes :
None specified - Prior Knowledge :
Items may require the student to apply science knowledge described in the NGSSS from lower grades. This benchmark requires prerequisite knowledge from SC.3.P.10.1, SC.3.P.10.3, SC.3.P.10.4, SC.4.P.10.1, SC.4.P.10.3, and SC.5.P.10.1.
SC.7.P.10.2 Observe and explain that light can be reflected, refracted, and/or absorbed.

STEM Lessons - Model Eliciting Activity
Students will analyze sets of data to determine what construction company proposal would be best suited for building an outdoor concert venue. Students will need to consider sound quality to the concert patrons, disturbances to the local community, and safety.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Virtual Manipulatives
This resource is a virtual manipulative that allows the user to change the angle of incidence of light and select from a variety of materials, each of which has a different index of refraction, to demonstrate how light may be refracted.
Type: Virtual Manipulative
This tool is useful for introducing students to the concept that light or electromagnetic waves pass through different substances at different speeds and in different directions.
