Sound Waves & Mechanical Waves 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 Sound Waves & Mechanical Waves.

Driving question: "How do different barrier materials influence the reflection, absorption, and transmission of sound waves?" Objective: Measure sound transmission loss across varied barrier materials using a calibrated sound source and decibel meter to classify materials by acoustic performance.

What's inside: objective and background, a materials list (One acoustic testing box (cardboard or…; One smartphone or digital tone…; One digital sound level meter…; Five standardized test barrier panels…), 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 650 words (~4 pages).

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