If she is getting ready to menstruate then yes it is possible for her to be more moody. However, I would start with school, friends, and home life first. It is usually a change in friends and environment that cause behaviors to change drastically in a short period of time. Hormones changing won't help, but generally kids her age are making friends and finding out more about themselves as individuals. Just talk to her, but don't scold her, just try to find out what is going on in her life. Don't be nosy though, just act interested, even if you aren't. She may not tell you everything, but you will find out more than if you are just asking her why she is so moody lately. Don't even tell her that you notice, just try to figure it out on your own and then deal with it accordingly.
