Please can anyone recommend a book for my 5 year old. He asks all sorts of wondeful questions like "Why does the wind blow" or "Why is the sky blue" or "How do you know the chair doesn't disappear when you turn around". He's a bit ahead of himself with the last one....! I can talk philosophy, but I'm no scientist, and although my husband can explain these things, I would love a book called something like "Why does the wind blow and other interesting questions" ....
Thanks!
