Help Needed ...about ISLAM

HI

I hav a religious spiratual assignment due next tuesday. One of the questions talks about milestones and key religious or spiratual events, sacraments,services or celebrations

I had to take religion through out all four years of my high school, since i go to a Catholic school, last year we learned about different religions including Islam, and it talked about some milestones, and unfortunatley i threw all my religion notes away

SO cut to the chase, i was wondering if any one can tell me few milestones of Islam such as "naming a child", "saying adhaan when a child is born", "shaving the head" and "death"

Thanks

Nida
