Scratch

Now I have a project I'm working on for a social studies term paper (ugh). So I chose Nuclear Weapons. Now I want to introduce Scratch to my school so what I'm working on is creating something to show my teacher. Basically a basis of how a nuclear bomb works and the explosion. So my question is just plain this.

Would It be appropriate if I posted a project like that and then still keep it up for all to see? I'm in the basis of creating it. (I have the idea planned out and everything but nothing started as of the time of this post). So would I be able to. i want to make sure that way I don't accidentally post something I shouldn't and get in trouble because i posted it.  So that's just it. 

Please tell me soon because well we are sort of in a war unit right now and I want to show it to him and my class before we're done with it.

Thank you for your time.
