A.P.
I don't personally have daughters but I have several thoughts.
My boys both went through a "screaming" phase around 8. It was also coupled with a very bad self-righteous and very ungrateful attitude. I think someone else posted something similar about a child that refused to do chores or help out and was screaming at and belittling parents.
8-11 is a weird age range. My boys are 11 and 9 so I am still going through it some but its on the tail end I hope. They are gaining some more independence and a huge amount of more awareness socially. As with every other time in their life you have to adjust and learn to teach them how to cope with this new realm of the world they have just discovered.
Some of my comments are the linked posts below. General gist is with this attitude you need to apply a bit of work. Implement chores and let them gain some appreciation for all the work you do to make their life nice! Also just talk to them and ask whats up when neither of you is mad.

Another suggestion... not sure if the women in your family start early or not. Some girls by 8-9 start showing signs of menstruation and hormones. A friend of mine said her daughter was a ticking time bomb of wildly flying and different emotions for about 6 months before she started her period.
If you really don't think either of these things is the issue, I suggest just taking her out for a girls day just the two of you. Talk to her when you aren't mad and ask her whats going on. Give her a chance to tell why she is acting that way. Try to compromise and let her know that its just making things worse. Try to be calm and let her speak her mind. Instead of correcting her ask her questions to get her to figure out the right answers.
Good luck.
