(4) K-3 Illustrated by Paolo Rui. Macdonald places an inquisitive boy at the scene of Galileo's famous experiments with gravity and falling objects. Though the science itself is murky, the process of scientific discovery is elucidated in an engaging, clear manner. Rui's sun-drenched acrylics are adequate to the task of explication while also setting the scene in 1589 Pisa. A useful book for elementary physics lessons.
