Why Can't I Hear That?: Pitch and Frequency

(4) K-3 Exploring Sound series. The physics of sound, including pitch, frequency, vibration, and speed, are clearly and cleanly explained. The texts are aided by many color photos, diagrams, sidebars, and captions, though some busy spreads aren't designed well. Activities (e.g., making a trumpet from a bottle, tube, and paper) are varyingly feasible for a child. Accessibility and an encouraging tone strengthen the presentation. Reading list. Glos., ind. Review covers these Exploring Sound titles: Making Noise! and Why Can't I Hear That?.
