Introducing the Girl Scouts Cadette Journey Breathe Book. Air is everywhere in this journey for sixth, seventh and eighth graders. As the girls explore the air all around them, they'll learn a lot of air-clearing strategies, including how to turn down the volume! That means they'll be improving their personal air space - and finding the breathing room necessary to be leaders who make the most of their special flair! The Cadettes will also meet scientists, engineers, writers, and artists - all of them working for Earth's air! Imported.
