Summary Use a circuit with a bulb or buzzer, to send morse code messages. Science content Physics: Electricity, Electromagnetism (7) Science competencies (+ questioning + manipulation + others that are in every activity) Planning/conducting: data collection/recording (K up) Planning/conducting: planning investigations (3 up) Lessons activity is in Electric circuits Resource Electricity Materials a simple circuit containing a bulb and battery, either made with home made wires and bulbs or purchased components morse code worksheet (see attachment - two long worksheets on a sheet) Procedure Students make a circuit containing a bulb and a battery, but keeping it open so that they can turn the light on and off by closing the circuit. Pair students up to send messages to each other. Give each student a morse code worksheet. Using the worksheet attached, cut half way across the worksheet as indicated, then fold where indicated. The folded up half will hide their message to send from their partner. Try at first with a very short message or abbreviation. Discuss the skill required to send and decode morse code fast.
