General Lesson Information
 Lesson Plan ID: 35563 Title: Discovering and Applying Ohm's Law Overview/Annotation: Students will design an experiment to relate the voltage difference and current in a circuit. They will collect data, then create and analyze a graph in order to arrive at Ohm's Law. They will create circuits and determine the voltage difference, current, and resistance in the circuit using Ohm's Law.This lesson results from the ALEX Resource Gap Project.

Content Standard(s):
 Science SC2015 (2015) Grade: 9-12 Physics 12 ) Use the principles of Ohm's and Kirchhoff's laws to design, construct, and analyze combination circuits using typical components (e.g., resistors, capacitors, diodes, sources of power). Unpacked Content Scientific And Engineering Practices:Analyzing and Interpreting DataCrosscutting Concepts: Cause and EffectDisciplinary Core Idea: Waves and Their Applications in Technologies for Information TransferEvidence Of Student Attainment:Students: Design combination circuits using typical components. Construct combination circuits using typical components. Analyze combination circuits using Ohm's and Kirchhoff's laws.Teacher Vocabulary:ammeter voltmeter series parallel model Kirchhoff's laws Ohm's law resistance current electric potential multimeter positive negative electrical components circuit voltage source conductors resistor color code circuit diagram heat charge static electricityKnowledge:Students know: The color code for the resistance of resistors. The basic principles of static electricity. How to construct electrical circuits. Several different components can be used to build an electrical circuit.Skills:Students are able to: Design and use models. Develop an appropriate experimental procedure. Create a data sheet. Collect and organize experimental data. Follow written and verbal instructions. Make measurements using standard units. Effectively manipulate laboratory equipment. Work safely in collaborative lab groups. Manipulate equations. Interpret graphical data. Solve mathematical equations. Use a multimeter.Understanding:Students understand that: Circuits are complete pathways through which current will flow predictably and will provide energy to the connected component(s). Circuits may be simple or complex.AMSTI Resources:ASIM Module: This standard could be met by minimal use of mathematics, however, the incorporation of more rigorous mathematics would deepen the students' knowledge.
