Invisible: Air

You cannot see air, but you live inside it.

Invisible: Air is a real-photo science picture book for ages 4–6 that makes the atmosphere observable through evidence and simple experiments. Children investigate pressure, wind, breath, sound, oxygen, weather, and the invisible gas surrounding Earth.

Each concept follows THE THING · THE EVIDENCE · DO IT HERE, naming an invisible phenomenon, giving real evidence for it, and offering a way to make it noticeable in everyday life.
