About the Lesson
Adapted from a PhETTM simulation, this lesson uses a simulation environment for constructing electric circuits. Students construct simple series circuits and measure voltage and current. They also work with equations relating voltage, current, and resistance. A guided lesson video (optional) is also available for this activity. The video is targeted at students and designed to help guide them through the interactive exploration and the concepts covered within. (It may also be helpful for teachers who may be using the activity for the first time.)
As a result, students will:
- describe an electric circuit
- use formulas to calculate resistance, voltage and current
- construct series circuits
