(3) K-3 Let's-Read-and-Find-Out Science series. Illustrated by Kasia Nowowiejska. Zoehfeld introduces the physics behind telephones, both historic wire-connected and current cellular versions, at a level that is appropriate for the targeted young audience. The text is accompanied by cartoonlike illustrations of children and historical figures inventing and using phones. A build-your-own string telephone activity is elevated by its focus on the engineering practices of revising and retesting the original design. Timeline. Glos.
