Students change the pitch and volume of a sound wave and discover that every sound — from a whisper to a drum — starts with something vibrating.
Students will be able to…
You can’t see sound, but you can feel it buzz. What is actually moving when something makes a noise?
Project this and let students change the pitch and the volume. Have them describe how the wave changes and connect each change to a sound they know.
Tap any phase to open the teacher moves and student actions.
Hum with a hand on your throat. What do you feel?
Students shape the wave with two sliders.
Two dials on every sound.
How does sound reach your ears?
Three quick checks on sound.
Aligned to Next Generation Science Standards and Common Core literacy. State-standard crosswalks available on request.
Develop a model of waves to describe patterns in terms of amplitude and wavelength, and that waves can cause objects to move.
Generate and compare multiple solutions that use patterns to transfer information.
Interpret information presented visually and explain how it contributes to understanding.
Write informative/explanatory texts to examine a topic and convey ideas clearly.

Connect two cups with a tight string and have students talk through it — proof that sound vibrations travel through a solid. A printable build-and-test sheet is in the Science library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
A quick self-check with instant feedback, drawn from this lesson’s key terms.
