[HS.PHY.2.9] - Evaluate simple series and parallel circuits to predict changes to voltage, current, or resistance when simple changes are made to a circuit.
Clarification Statements: Predictions of changes can be represented numerically, graphically, or algebraically using Ohm’s law. Simple changes to a circuit may include adding a component, changing the resistance of a load, and adding a parallel path, in circuits with batteries and common loads. Simple circuits can be represented in schematic diagrams. State Assessment Boundary: Use of measurement devices and predictions of changes in power are not expected in state assessment.
[WCA.9-10.2] -
Write informative/explanatory texts, including the narration of historical events, scientific procedures/ experiments, or technical processes.
[AI.A-CED.A.4] -
Rearrange formulas to highlight a quantity of interest using the same reasoning as in solving equations (Properties of equality).* For example, rearrange Ohm’s law R=V2/P to solve for voltage, V. Manipulate variables in formulas used in financial contexts such as for simple interest, I=Prt.
[AI.A-REI.B.3.a] -
Solve linear equations and inequalities in one variable involving absolute value.
[AI.F-LE.A.1.b] -
Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.*
[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.3.2] -
Develop and use a model to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles and objects or energy stored in fields. Clarification Statements: Examples of phenomena at the macroscopic scale could include evaporation and condensation, the conversion of kinetic energy to thermal energy, the gravitational potential energy stored due to position of an object above the earth, and the stored energy (electrical potential) of a charged object’s position within an electrical field. Examples of models could include diagrams, drawings, descriptions, and computer simulations.
