STEM CLASS: ASSEMBLING A SIMPLE SERIES CIRCUIT
On May 21, 2026, the students at the Center for Research and Education of the Deaf and Hard of Hearing (CED) together participated in a STEM class themed "Assembling a Simple Series Circuit."
The session consisted of two main parts:
• Part 1: Exploring components from old fans The students disassembled old fans to observe and learn about the internal components, including the motor, wires, fan blades, and batteries. Through this activity, they gained a better understanding of the structure and operating principles of a simple electric fan.
• Part 2: Practical fan assembly Using the components they had explored, the students practiced assembling a fan with a series circuit consisting of a 130V motor, wires, fan blades, and batteries. Their focused faces and skillful hands, careful in every step of wiring, suddenly turned into joy and excitement as the fan blades began to spin. That was also the moment the circuit was safely and effectively assembled.
During the session, although they did not dive deep into the theory of series circuits, the students were fully exposed to all four elements of STEM:
• S (Science): Actively observing how a fan operates—turning the fan on/off to see the blades spin when electricity is present, and learning how to connect positive and negative wires in a circuit.
• T (Technology): Observing and discovering the structure of a mini fan, and identifying components such as the motor, wires, battery, and fan blades.
• E (Engineering): Practicing disassembling, wiring, and assembling different parts.
• M (Mathematics): Measuring and estimating the sizes of the components, determining appropriate assembly positions, and arranging the parts symmetrically to ensure the fan operates stably.
Beyond fostering meticulousness, concentration, teamwork, and problem-solving skills, the STEM lesson themed "Assembling a Simple Series Circuit" also ignited a love for science, creativity, and the discovery of applied technology in daily life.
Most importantly, it reaffirmed the belief that "Anything is possible."
