Analog vs. Digital Signals in Technology Interactive Simulation | Physical Science | Grades 6–8

This Interactive Simulation has grades 6–8 Middle School Physical Science students run a hands-on classroom model of Analog vs. Digital Signals in Technology.

Driving question: "How do analog and digital signals respond to noise interference during electronic transmission?" Objective: Compare signal degradation and data recovery between continuous analog waveforms and quantized digital binary pulses across simulated electrical noise levels.

What's inside: objective and background, a materials list (One electronic waveform function…; One dual-channel digital storage…; One electronic breadboard with a…; One analog-to-digital converter (ADC)…), an 8-step protocol, a data table, 4 analysis questions, and teacher notes.

Resource type: Interactive Simulation (.docx). Format: editable Microsoft Word lab handout with approximately 670 words (~5 pages).

Classroom use: a team investigation in a Middle School Physical Science course. Grades 6–8.
