D.I.Y. Science – Morse Code

Please login to favourite this article.

The D.I.Y. Science series contains some of our favourite experiments for kids to try at home. They are designed to help primary school teachers and carers inspire a child’s curiosity in science. It’s time to get hands-on.

This episode shows how to make an electrical circuit with a buzzer to create Morse code.

It is best suited to year 6 students to introduce them to how we actually use electrical circuits and their particular use for communication.


Create your own Morse Code by building an electrical circuit.
