Please recommend a good book about physics for young child (elementary school aged) I'm looking for a book that would be appropriate for an advanced elementary school aged kids (say, 6-11 YO) describing the basics of physics (or sciences in general) in entertaining way. 


*

*The structure of the book should preferably (though not necessarily) be "Curious question" followed by entertaining-but-advanced for their-age physics answer.
As a good example of a chapter/story I had in mind:
"Why can the soap wash off dirt/grease?"
"Why can the water be poured into containers?"
"How does a plane fly?"
"How does a rocket fly?"

*The topics that must be covered are atoms/molecules, how they go together to make various matter etc...

*Doesn't have to be 100% limited to physics - could include chemistry, biology, other natural sciences. 
P.S. For those fluent in Russian, i'm looking for an English equivalent of the soviet popular kid's physics/science book "почему вода мокрая").
 A: English translation of Perelman's "Physics for Entertainment" may be found at amazon http://www.amazon.com/Physics-Entertainment-Book-Yakov-Perelman/dp/1401309216.
A: I should think an eight year old interested in physics would be able to handle Bill Bryson, "A Short History of Nearly Everything". Bill Bryson is of course a non physicist. But what I loved about this book is that, remembering being fascinated by science himself as a child, he delights in the how we know just as much as the facts themselves. The flavour of the book is very much about the scientific method, and for a non-scientist to capture this in so lively, and poetic, a way is astounding. The book opens with a description of himself as a seven year old looking at a cut open view of the inside of the Earth and being gobsmacked by the thought "How the hell do we know that?!". An example of the book's flavor is his description of the CBMR, which he adds poetry to by noticing parenthetically that it accounts for about 1% of the interference in the VHF television bands. So, he says, if you're bored and can't find anything on cable, you can always switch to an unused channel and watch the birth of the Universe!.
A: A good book (and accompanying website) is Flying Circus of Physics.
