Lesson Focus
Demonstrate how two switches interact in an electrical circuit such as that used to sound a buzzer. Note: This lesson plan is designed for classroom use only, with supervision by a teacher familiar with electrical and electronic concepts.
Lesson Synopsis
The Two Button Buzzer Circuit activity explores an everyday situation, where either of two or more buttons can ring a buzzer. Students learn how this type of circuit is structured, draw a schematic for it, and construct a two button buzzer model out of wires, a battery, buttons (switches), and a buzzer.
Age Levels: 8-14
Objectives
- Learn how switches control the flow of electricity.
- Learn to draw basic wiring diagrams.
Learn about teamwork and working in groups.
Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
- switches
- circuits and current
- basic electrical diagrams
- making and testing predictions
- teamwork

Lesson Activities
Students learn how two buttons (switches) can control a buzzer. Student groups then draw a schematic of a two button buzzer circuit and build a model of the circuit using wires, a battery, buttons (switches) and a buzzer. Final schematics are shared with other groups, with results and findings discussed as a class.
