A colorful but flat and educational e-book cover. The design should include: – A vivid blue background to symbolize air and oxygen – A detailed illustration of the human respiratory system (lungs, trachea, nose) at the center – Children learning in a classroom on one side, and a child running outdoors on the other to represent active breathing – Icons of oxygen (O₂), carbon dioxide (CO₂), and air particles floating lightly around – A modern educational style with clear labeling, soft shadows, rounded shapes, and playful but neat typography Make it vibrant, informative, and engaging for young science learners.
