Planning A Middle School Party?

My mom said if me and my sisters get doing our schoolwork a little more (we're homeschoolers) we maybe could have a highschool-type party (with music, food and drinks, stuff like that.) What could I do for this party? I was just thinking of moving some furniture out of the kitchen/family room and making that a dance floor. Any ideas for food and drinks? (I thought of different kinds of soda and pizza) If we're making this a sleepover we're gonna make the boys sleep in the kitchen, living room, and the garage. :)
