SOUNDS ALL AROUND

This appealing Stage 1 title in the Let's-Read-And-Find-Out Science series provides a simple explanation of sounds and hearing. Beginning with snaps, claps, and whistles, Pfeffer describes how sound waves vibrate through the air, and how tiny bones in the ear vibrate. She also explains how animals hear, from bats and echolocation to whales using sound waves to locate their young in the ocean, and notes that sound waves travel through the solid ground as well as air and water. Keller's charming illustrations show very young children, so the title may not draw in older readers. Still, with its suggestions for activities and clear language, it's a welcome addition to the series.
