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").
