Lesson 3-Explore/Explain Do You Hear What I Hear?
Students explore how loudness is measured. They identify the decibel scale and explain the amplitude of the sound wave.
Curated OER
Good Vibrations
Students demonstrate sound waves and make changes in the waves
resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.
