How cool! This plan uses old cassette tapes to show frequency from traveling vibrations. To prepare for the lesson, tactile frequency diagrams are made and then placed near the video tapes or dominoes that are already set up. When they are pushed, the way they fall will mimic the frequency diagrams. This is a fantastic way to demonstrate a complex concept to your learners with visual impairments.
