Two Button Buzzer Circuit

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.

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

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.
