In this lab activity for Grades 5-9, students work in teams to construct a simple telegraph using a battery, wires, and a bulb. By turning the switch on and off, learners "send" messages using International Morse Code. Students then repeat the process sending identical messages on cell phones. Which group can send intelligible messages most quickly? What is the time difference between the fastest Morse Code operator and the slowest texter? The driving question of the lesson: How has society been impacted by the contributions of early pioneers in electromagnetism and its applications?
This instructional module includes goals/objectives, Power Point introduction, problem sets, student guides, recommended reading, illustrated procedures, worksheets, and background information about the engineering connections.
