Why we let kids take things apart
An old radio teaches more than a new kit. How we use broken things in class, and how to try it safely at home.
In one corner of every CircuitKids classroom there is a box of broken things: old radios, keyboards, toy cars, a printer or two. Children are allowed to take them apart. Some weeks, it's the most popular part of the class.
What children learn from a broken radio
A new kit is designed to be understood. A real object isn't. Inside a radio, children find parts that don't match any diagram. They have to look closely, guess, and check.
They see real circuit boards, not only the tidy ones in books.
They learn that every object was designed by someone, for a reason.
They practise patience: screws are small and some are hidden.
How we do it in class
Every take-apart session follows the same three steps. First, we look and guess what's inside. Then we open it carefully and lay every part on a tray in order. Finally, each child picks one part and tries to explain what it does.
The goal is not to fix it. The goal is to understand it well enough that you could.
Trying it safely at home
You don't need special tools. A small screwdriver set and a tray are enough. But please follow a few rules:
Never open anything that plugs into the wall. Old power supplies and microwaves can hold a charge long after they're unplugged.
Remove all batteries first, and never open a battery.
Avoid screens and old TVs. They can contain glass and chemicals.
Good choices: wind-up toys, old keyboards, battery toys with the batteries out, mechanical clocks.
Take a photo before each step. It makes putting it back together possible — and makes a nice record of the afternoon.
