The science, history, and cultural significance of the shortest day of the year: The Winter Solstice! The beginning of winter is marked by the solstice, the shortest day of the year. Long ago, people grew afraid when each day had fewer hours of sunshine than the day before. Over time, they realized that one day each year the sun started moving toward them again. In lyrical prose and cozy illustrations, this book explains what the winter solstice is and how it has been observed by various cultures throughout history. Many contemporary holiday traditions were borrowed from ancient solstice celebrations. "Using clear, concise language, Pfeffer discusses important ideas behind the shortest day of the year, such as the change from autumn to winter as well as the concept of the Earth's tilting away from the sun…. While appealing to a younger audience, this treatment combines the cultural approach of Ellen Jackson's The Winter Solstice (Millbrook, 1994) and the activities of Sandra Markle's Exploring Winter (Atheneum, 1984; o.p.). Pfeffer uses an easy, comfortable tone for conveying the basic information, and the end pages will provide additional opportunities for would-be astronomers to explore the principles on their own." —School Library Journal Simple science activities, ideas for celebrating the day in school and at home, and a further-reading list are included.

Describes the metamorphosis from tadpole to frog.

Winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series A tadpole is a baby frog! Female frogs lay masses of jelly-coated eggs in the water, but what hatches from each egg isn't a frog yet—it's a tadpole. Tadpoles are likely tiny fish that breathe underwater through gills. As the tadpole gets older, it loses its fishy tail and its gills and grows legs and develops lungs. The tadpole has become a frog. From Tadpole to Frog is a lovely first look at this amazing metamorphosis.
