01 / UNDERSTAND

Here is what is happening.

Sound begins with vibrations. When you hum softly, you may feel movement at your throat. A drawing cannot show sound directly, so we use clues such as movement or what we hear. People can notice vibration by touch too. A louder sound is not automatically a better observation.

Pause. Make the idea your own.

Explain one idea to a partner, draw it or write it in your own words. Which part is an observation, an example or a question?

You can use a home language. No need to share personal experiences or finish everything in one sitting.
02 / MAKE IT YOUR OWN

Your little investigation

What you need

Paper and a pencil, or a partner to talk with. Drawing and speaking are welcome.

  1. Hum softly; if comfortable, rest your fingers lightly on your own throat.

  2. Stop humming and compare. Describe what you noticed without shouting.

  3. Draw two panels: humming and quiet. Add arrows for movement you felt.
