Science: making a Morse Code circuit

We are good at making circuits now, and we can identify which part of the circuit is not working if the bulb does not light. We find out by borrowing parts from other groups whose circuits are working. By testing one part at a time, we can find out which of our parts is no good, and we can ask for that part to be replaced. Well done, circuit troubleshooters!

When we had all our circuits working properly we tried using Morse Code to flash our names. You can see the Morse Code on the board above. It has been used for many years to send messages. People who use Morse Code all the time have learned it by heart, but we do not need to learn it. We can look it up online if we need it.
