(3) K-3 Cycles series. Illustrated by Gustav Moore. Defining cycles as "events that repeat over and over again in the same way," Ross discusses Earth's daily cycle of light and dark, the thirteen lunar cycles, and Earth's yearly trip around the sun. The simple text provides very basic information about periodicity and uses familiar examples to introduce new concepts ("the Earth...goes round and round like a very slow top"). Pleasing watercolors expand the text.
