Objectives:
BIG IDEA 1: Objects and systems have properties such as mass and charge. Systems may have internal structure. BIG IDEA 3: The interactions of an object with other objects can be described by forces. BIG IDEA 5: Changes that occur as a result of interactions are constrained by conservation laws. Objectives:
Science Practices: 1,2,4,5,6,7
1.B.1.1: The student is able to make claims about natural phenomena based on conservation of electric charge.1.B.1.2: The student is able to make predictions, using the conservation of electric charge, about the sign and relative quantity of net charge of objects or systems after various charging processes, including conservation of charge in simple circuits. 1.B.2.1 The student is able to construct an explanation of the two-charge model of electric charge based on evidence produced through scientific practices. 1.B.3.1: The student is able to challenge the claim that an electric charge smaller than the elementary charge has been isolated. 1.E.2.1 The student is able to choose and justify the selection of data needed to determine resistivity for a given material. 3.C.2.1: The student is able to use Coulomb’s law qualitatively and quantitatively to make predictions about the interaction between two electric point charges.3.C.2.2: The student is able to connect the concepts of gravitational force and electric force to compare similarities and differences between the forces. 5.A.2.1: The student is able to define open and closed systems for everyday situations and apply conservation concepts for energy, charge and linear momentum to those situations. 5.B.9.1: The student is able to construct or interpret a graph of the energy changes within an electrical circuit with only a single battery and resistors in series and/or in, at most, one parallel branch as an application of the conservation of energy (Kirchhoff’s loop rule). 5.B.9.2: The student is able to apply conservation of energy concepts to the design of an experiment that will demonstrate the validity of Kirchhoff’s loop rule (∑ΔV=0) in a circuit with only a battery and resistors either in series or in, at most, one pair of parallel branches.5.B.9.3: The student is able to apply conservation of energy (Kirchhoff’s loop rule) in calculations involving the total electric potential difference for complete circuit loops with only a single battery and resistors in series and/or in, at most, one parallel branch. 5.C.3.1: The student is able to apply conservation of electric charge (Kirchhoff’s junction rule) to the comparison of electric current in various segments of an electrical circuit with a single battery and resistors in series and in, at most, one parallel branch and predict how those values would change if configurations of the circuit are changed. 5.C.3.2: The student is able to design an investigation of an electrical circuit with one or more resistors in which evidence of conservation of electric charge can be collected and analyzed. 5.C.3.3: The student is able to use a description or schematic diagram of an electrical circuit to calculate unknown values of current in various segments or branches of the circuit.
