We teach the kids about electrical circuits, batteries, motors, resistance, voltage, amperage, and power.
One of the first things we teach is that a circuit is a circle that electrons can move around.
The circle has to be made of a conductor like copper or aluminum but any metal will suffice.
As will water, carbon, people, and some other things.
Then they each build a lamp.
They decorate, wire, and test it.
Then take it home for their own use or for a Christmas present for their mom, grandma or whomever they choose.
The kids paint the pots that would be the base of their lamps.
Nancy encouraged them to be creative.
If they planned to give the lamp to to someone as a present, make it suit the recipient.
Here are a few of them.
Here are the parts of the lamp (pot not yet painted) laid out in the order they will be assembled.
Here they are collecting the parts that they need.
We explained that the components they were using had been certified by the Underwriters Laboratory as safe if connected properly.
They searched for this symbol on the socket, it's case and the wire. It appeared 6 times in various places
They also discovered that the wire was rated for 103 degrees C and 300 volts.
They need a stress relief where the wire goes into the socket to be sure that it isn't pulled loose by an accidental tug.
One acceptable way to provide that is an underwriters knot.
These diagrams show how to tie it in the wire.
The knot is just inside the base of the socket and prevents a pull on the cord dislodging the electrical connections.
