At first glance, you might think this is a silly book about animals operating a submarine. Perhaps you might even think there is little accurate information in this book because of the outrageous illustrations, but you would be wrong!
Yes, there are animals walking on two feet and dressed in uniforms operating this 'submarine', but there is a ton of accurate, nicely-labeled information about various parts of a submarine. If you have an early reader or younger reader who enjoys books about big machines--this is a great add to your collection.
"A submarine must have a crew to run it night and day. The crew needs living quarters, where they eat and rest and play." Although the language is mostly accessible for my first grader, we enjoyed bits like this because we were able to learn (yet) another meaning for the word "quarters". The back page even has a glossary detailing some submarine parts.
This is part of a 'machines' series and I think would make a nice addition to any classroom library to spark conversation and interest in machinery topics.
