Grades 9-12: In this lab, students learn about electrical properties, circuit wiring and diagrams, and how voltmeters and ammeters are used.
PHYSICAL SCIENCES (Grades 9-12)
This tutorial/lab leads students through a series of readings and experiments to develop an understanding of voltage, current, and resistance; how simple circuits are diagrammed and wired; and how voltmeters and ammeters are used. The students collect and graphically analyze voltage and current data for a resistor in a simple series circuit. As the students interpret their graphs, they ‘discover’ Ohm’s Law. The final phase of the experiment asks the students to test their understanding of the concepts in the lab by determining the resistance of a resistor which is unknown to them.
