The clear, sweet prose makes delivery of the content easy, and the very fine, soft illustrations demand repeated veiwing. My Preschool and Kindergarten ESL students found it highly engaging.

If there's a better science and read-aloud book around I'd really like to know about it. TEN stars.

Follow this book up with the superb "Is a Blue Whale the Biggest Thing There Is?" by Robert E. Wells. Wells' book uses the whales' size as a starting point for exploring the size of the universe and other very big things (the second step involves putting a hundred blue whales in a really big jar). Read my review of Wells' book if you like.
