It's definitely two double bonds, sometimes the dot and cross don't add up to the final structure. Check with your teacher when your back at school perhaps?

Same link you gave, check down, under structure and bonding...
The definitive structure is classed as two double bonds, but because it has a resonance, it's classed as two double bonds.
Right, so is O-S=O wrong, or is it a must to add two double bonds. After all the pi bond is resonant, therefore wouldn't it make more sense if the structure was drawn with one double bond at a time?

It's hard to describe, but the molecule alternates in resonance. At one split second, it's O-S=O, the next split second it's O=S-O, therefore, strictly speaking we can't really say the fixed structure is O-S=O, but instead the scientists just assign it as O=S=O. I hope that's a little clearer now.
But when you study unit 5, you will come across benzene and the resonance structure is has.

Isnt there a student book? And whats the diff between this and the student book?
The student book is full of crap. Nothing in it for the exams. "How science works" is the only thing you need to read in it. This book is a better guide. ....lol big difference.
