Bound To Stay Bound

Booklist - 03/01/2024 This beginner science text explains in easy-to-understand terms and formatting how important air is to life on Earth, including in the sky, underground, and in the sea. To make the learning process accessible, the author employs Puff, a cute mass of air who has been on Earth since the planet's inception. Cheerful illustrations reveal Puff as a small, smiling, circular being with a swirl on his forehead. Puff and his friends are the reason Earth is warmer than outer space and protected from excess radiation. Humans and other animals breathe in oxygen and exhale carbon, which along with nitrogen and a few other gases make up air. Sometimes Puff moves fast, as in a rainstorm or tornado, while other times he is a gentle breeze. Puff is even capable of spreading seeds and therefore promoting more life on Earth. The book begins with an explanation of the gases that combine to create air and ends with an informational page titled, “How Does Air Move?” - Copyright 2024 Booklist.
