This book, as well as it's companion "Why Do Stars Twinkle?" make great reads for kids and parents. The short explanations of questions keeps kids interested and leaves the door open for demonstrations and discussion. I highly recommend it!

The questions children ask most while in the kitchen with you. Each question and answer are simply formated for the most information with the easiest understanding. I used this book for a library reading session with 2nd graders, asking them the questions first, finding their thoughts then reading them the answers from the book. They absolutely loved it and wanted more. I am now online to order the rest of the series!!! It is perfect for every age, even us older kids!!

This is a great book for curious pre-schoolers. My three year old and especially my four and a half year old love this book. It answers basic questions very well, with good illustrations and simple, but very correct explainations.

My 3 year old has already asked me many questions in this book,
so it hits the mark on being full of real questions that a real child would ask. The explanantions are short (about 1 paragraph)
and easy to understand - although I found the vocabulary sometimes a bit tough for my 3 year old. I often used simpler words while reading to her. I expect therefore that the rated age range beginning with 4 years is probably accurate from the point of view of understanding the explanations completely. The questions are arranged in groups such as "bathtime questions" and in a "story" order revolving around a child in that particular situation (ie. the child is getting a bath and is asking questions that start with "how does hot and cold water run out of the same tap" and ending with "why do my hands get all wrinkly after I've been in the bath a long time"). Each question and it's associated exaplanation and illustration cover a full two-page spread of the book. My only complaint is that the book does not actually contain as much detailed "science" content as I had hoped to find - since it is based on questions that children ask, not on concepts someone wanted to include purely for the sake of completeness. I would guess that 8 year olds might be left wanting more information that is given in the answers (which could be considered a good thing, spurning them on to further research). Certainly for the younger ages though, this is a great book. (More questions from the book: "Do the doors at the grocery store open by magic?" "Why do stars Twinkle?" "Why does it smell so good outside after it rains?" "Why do I have to use the toilet and where does it go when I flush?")
