A humorous story about taking turns and the science behind Earth's day-and-night cycles. 

When the daytime and nighttime animals on Earth get tired of Sun and Moon's constant bickering over who should rule the world, they hold competitions—a cookout and a race—to determine the winner once and for all.

But when neither the "night" team nor the "day" team wins in a fair way, how will they fix their problem?

This beautifully illustrated story teaches kids respect for nature's rhythms and each other. It includes a guide that helps parents and teachers explain the science of Earth's day-and-night cycles in simple language.[AuthorName]By Lili DeBarbieri and Illustrated by Katie Wools[/AuthorName][AuthorBio]Lili DeBarbieri is a Tucson-based author of award-winning travel guidebooks, picture books, and historical fiction.
