The Year 3/4 Class finished constructing their Morse Code signalling devices in STEM last week. Previously the students have experimented with electrical components and how to use batteries, bulbs and switches to make a simple circuit.
We then learned how Morse Code works and how Morse can be transmitted by sound, electrical pulses or by light. We coded our names in Morse and tried tapping signals to each other.
To make our Flashers, we used a clothes peg as a ‘momentary on’ switch, and connected it to a 3V battery pack and a LED. The LED was mounted on Corflute and glued to a wooden board.
Joining the wires was quite fiddly and the students had to persevere to make their Flasher work correctly, but the process and end result was most rewarding!
