A free, printable worksheet that introduces students to the basics of radio communication through a simple matching exercise. Using a labeled diagram of a transmitter and receiver setup, students connect six modular components: microphone, transmitter, amplifier (transmitting), amplifier (receiving), receiver, and speaker, to their correct place in the signal chain and identify what each one does.
Perfect as a warm-up activity, homework sheet, or lead-in to QASE Tech's Space QASE Radio Communication kit, this exercise builds foundational vocabulary and conceptual understanding of how sound becomes a transmitted signal and back again with no equipment required.
Ideal for: secondary school physics/STEM teachers introducing wave theory and communication systems.
Format: Printable PDF, single page.
Level: Beginner-friendly, curriculum-aligned.
