Will I go to jail for my first offense?

Will I go to jail for my first offense?
So Monday December 17 I was stupid and brought my BB gun to school. I had no intention on hurting anyone I was just showing my friend. I was caught and now the school is charging me. This is my first offence. I turned 18 on December 11th. Will I be going to jail?

This is a very serious offense. You should stop talking about the facts of your case online and look for an attorney in your area. Yes, you are possibly facing incarceration for this case.
