The Telegraph Sender

This is the boys' first project. Each boy cut his own boards using a jig saw and a scroll saw. They drilled the holes for the screws, wound their own coils to make their own electromagnets, and began to learn the meaning of the terms volts and current. We talked about electrons and electron flow through conductors and began to learn about electromagnetism and how it can be used. Next week we will make a very simple motor!
