SC.7.P.11.4

Observe and describe that heat flows in predictable ways, moving from warmer objects to cooler ones until they reach the same temperature.
Subject Area: Science
Grade: 7
Body of Knowledge: Physical Science
Idea: Level 2: Basic Application of Skills & Concepts
Big Idea: Energy Transfer and Transformations -

A. Waves involve a transfer of energy without a transfer of matter.

B. Water and sound waves transfer energy through a material.

C. Light waves can travel through a vacuum and through matter.

D. The Law of Conservation of Energy: Energy is conserved as it transfers from one object to another and from one form to another.

TEST ITEM SPECIFICATIONS

  • Item Type(s): This benchmark will be assessed using: MC item(s)
  • Also Assesses
    SC.7.P.11.1
    Recognize that adding heat to or removing heat from a system may result in a temperature change and possibly a change of state.

  • Clarification :
    Students will describe how heat flows in predictable ways.

    Students will explain that adding heat to or removing heat from a system may result in a temperature change and possibly a change of state.
  • Content Limits :
    Items will not address chemical changes.

    Items will not require calculations.

    Items will not assess the concepts of conductors and insulators or examples of either in isolation.

    Items will not require the use or memorization of formulas or values of specific heat, heat of fusion, or heat of vaporization for substances.

    Items may assess the concept of specific heat.
  • Stimulus Attributes :
    Scenarios addressing methods of heat transfer (conduction, convection, radiation) will not use an Earth Science context.

    Temperature will only be shown in degrees Celsius (°C).
  • Response Attributes :
    Temperature will only be shown in degrees Celsius (°C).
  • 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.9.1, SC.3.P.11.1, SC.4.P.11.1, and SC.4.P.11.2.
