Sun Up Sun Down The story of day and night

Sun Up, Sun Down: The Story of Day and Night is a children’s science book by Jacqui Bailey, illustrated by Matthew Lilly. It explains how sunlight, Earth’s rotation, shadows, the Moon, and Earth’s yearly orbit create the familiar patterns of day, night, and changing seasons.

Part of the Science Works series, the book uses lively storytelling and cartoon-style illustrations to make astronomy accessible to young readers. It also includes a simple experiment, science facts, useful websites, and an index.
