DS1 is obsessed with 'pure chemistry', and is fascinated by atoms and elements, and how they combine. I did get an A at O level a long time ago, but I don't think I deserved it, and can't remember anything about it.
He keeps asking questions like:
Why are Hydrogen and Oxygen both highly flammable and explosive?
And why is water not?
And what happens to the elements when something burns? Do they change chemically, or not?
Do you know of any textbooks or correspondence courses which might be suitable to satisfy his curiosity that are not too dry and turgid? (And enable me to stay one step ahead!)
He already has the sort of 'kitchen chemistry' books, and enjoys experimenting. But he seems to have a desire to learn the theory behind it, and as non-scientists we're both rather out of our depth
roisin - not really what you're asking, but I'm fairly sure as a kid I had the Usbourne Book (or Big Book?) of Science. It was 3 books in one (separated into Physics, Chemistry, and Biology) and it really sparked my interest in all things scientific. I'm not sure if it's in print anymore - I'm trying to do an online search now. But it sounds like it's the sort of thing you're after?
