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.
