I checked out this book from the library for my kids but ended up appreciating its wisdom much more than they did.
The underlying theme: Slow down. Stop. Listen. A compilation of 50 mindful moments in nature; from dew collecting on a leaf, the crest and break of an ocean wave, a mother duck teaching her ducklings to swim for the first time. Each page has exquisite illustrations peppered with scientific captions. The overall layout, number of illustrations, and attention to detail lends itself to engage both experienced and emerging readers alike.
