I Heard a Sound

Crickets, clarinets, and vocal chords. All vibrate. All make sound.

Here is science learning at it's best: a kid-friendly, accessible text, with bold, retro-styled illustrations, and hands-on experiments you can try at home!

Using everyday items like straws, balloons, rulers, and wax paper, readers can:

• See how sound can pass through a string
• Use four straws to hear high and low sounds
• Show how vocal chords work
• Use wax paper to see sound vibrate
• Learn how sound waves work

And much more!

A glossary is included in the back of the book.
