What's the difference of "house" and "home"?

What is "Breaking The Ice" actually? i ever read in one article about that. but i wasn't sure with it. the article said that Breaking The Ice is something like opening conversation with someone new. is that rite?

First notebook entry: Introducing myself Let me introduce myself, my name is Bianca Noorma Meydita. you can call me Bianca for short. i am an english teacher on senior high school 3 Pekalongan. As an english teacher sometimes i feel i am still lacking of my knowledge about english language. Beside that, i need to improve my students' spaking english. sometimes it is very difficult to ask my students to speak up even in one sentence. i hope, with joining in this community, i can share my problem on teaching english. And get some friends who can share each other. thank you...
