In this At-Home Science video, which aired on WJLA’s “Outside the Classroom” on May 27, 2020, Ali explores the physics of waves by building her very own wave machine with everyday materials.
The sounds we hear are caused by vibrations of a material, like the string of a guitar moving back and forth when plucked. These vibrations cause the air molecules to move allowing us to hear the sound in our ears. Students will learn how waves move through different materials and how components like wavelength, frequency, and velocity affect its motion.
