Make a Lighthouse

In this activity, learners explore the concept of lighthouses as communication systems. Learners are provided with materials to build simple paper lighthouse circuit. The Morse code is introduced as a means of communication, and learners use their lighthouses to transmit and decode messages. They are challenged to compose secret messages in Morse code, bridging the connection between decoding and coding. The activity culminates in a game where learners take turns transmitting messages using their lighthouses and Morse code in a dimly lit setting. The activity includes prompts to facilitate a discussion about the advantages and disadvantages of using light and Morse code for communication.
