Books in the I Wonder Why series

Guides children through six types of regions that are shaped by rainfall-or the lack thereof. Readers take a journey that starts with dense tropical rainforests and woodlands, travels through grassy savannahs and prairies, and ends at dry steppes and deserts. Throughout the book, attentive readers can compare how and why each region is alike and different.

What happens when two friends take an interest in an oak tree? They begin to notice more about the world around them, such as the seasons changing and squirrels making homes. As warm and dreamy as a summer day, Our Very Own Tree will inspire readers to seek out their very own places in nature.

By showing the same creatures in two different settings, this book brings out the detective in young readers. They can investigate the role of protective coloration for crickets, bumblebees, beavers, spiders, and spotted green frogs. The vivid examples encourage children to closely examine the characteristics of hidden creatures.
