Hi Katherina!
That's a very good idea. I think asking my students to look at this blog and your individual blogs too is a very good way of introducing them to the concept. Otherwise, they really will be gobsmacked (now there's an interesting word for you to look up). What about all of you? How did your teacher get you interested in the idea of blogging? What did she say that caught your interest? It's obvious that she did a good job!
