Core Idea - Motion and Stability: Forces and Interactions

[7.PS.2.3] - Analyze data to describe the effect of distance and magnitude of electric charge on the strength of electric forces. Clarification Statement: Includes both attractive and repulsive forces. State Assessment Boundaries: State assessment will be limited to proportional reasoning. Calculations using Coulomb’s law or interactions of sub-atomic particles are not expected in state assessment.

Predecessor Standards:

  • 6.SP.B.5
    Summarize numerical data sets in relation to their context, such as by.

Successor Standards:

  • HS.CHEM.1.1
    Use the periodic table as a model to predict the relative properties of main group elements, including ionization energy and relative sizes of atoms and ions, based on the patterns of electrons in the outermost energy level of each element. Use the patterns of valence electron configurations, core charge, and Coulomb’s law to explain and predict general trends in ionization energies, relative sizes of atoms and ions, and reactivity of pure elements. Clarification Statement: Size of ions should be relevant only for predicting strength of ionic bonding. State Assessment Boundary: State assessment will be limited to main group (s and p block) elements.
  • HS.PHY.2.4
    Use mathematical representations of Newton’s law of gravitation and Coulomb’s law to both qualitatively and quantitatively describe and predict the effects of gravitational and electrostatic forces between objects. Clarification Statement: Emphasis is on the relative changes when distance, mass or charge, or both are changed. State Assessment Boundaries: State assessment will be limited to systems with two objects. Permittivity of free space is not expected in state assessment.
  • HS.PHY.2.5
    Provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current. Clarification Statement: Examples of evidence can include movement of a magnetic compass when placed in the vicinity of a current-carrying wire, and a magnet passing through a coil that turns on the light of a Faraday flashlight. State Assessment Boundary: Explanations of motors or generators are not expected in state assessment.

Same Level Standards:

  • 7.RP.A.2
    Recognize and represent proportional relationships between quantities.
  • 7.NS.A.1.a
    Describe situations in which opposite quantities combine to make zero. For example: A hydrogen atom has zero charge because its two constituents are oppositely charged; If you open a new bank account with a deposit of $30 and then withdraw $30, you are left with a $0 balance.
  • 7.PS.2.5
    Use scientific evidence to argue that fields exist between objects with mass, between magnetic objects, and between electrically charged objects that exert force on each other even though the objects are not in contact. Clarification Statement: Emphasis is on evidence that demonstrates the existence of fields, limited to gravitational, electric, and magnetic fields. State Assessment Boundary: Calculations of force are not expected in state assessment.
