Raddy, I'm not sure if this would answer what little one asked above but most recently DD6 has been letting me know that the books she has are not interesting, so I took her to the book store and let her pick out anything she wanted, she picked The Usborne Internet-Linked Science Encyclopedia. This has so many answers with details on many subjects and after you read the page you can link to the internet
www.usborne-quicklinks.com give the page # like 174(space exploration) and it gives you more information, so far it's a hit in our house. good luck
