You’ve probably played Operation, the game where you’re a doctor armed with a pair of tweezers, trying to fix a patient with a big red nose.

The goal of the game is to remove things like bones out of small openings without touching the edge of the opening. Like most things, it’s much more fun when you make your own!

Using an LED, a buzzer and other materials you can make your own operation game to play with your friends and family. This is a great way to learn about parallel circuits. In a parallel circuit, each component has its own branch from the power source. If one piece breaks, the other one keeps on working. For this game, there are two branches: one for the buzzer, one for the LED.

Note! The electronic parts for the Operation Game come in our STEAM Programs.
