We want to raise awareness of certain issues in our school, but we're worried about getting in trouble. How can we safely set up an unauthorized gathering or activity in a school to increase awareness of certain issues?

One potential solution is to set up a makeshift “information station” in an inconspicuous area of the school, such as in a hallway or outside of a classroom. The station could contain information about the issue and provide resources on how to get involved or take action. Additionally, students could put on a display of artworks, photographs and poster detailing the issue which could draw curious students in and raise awareness. Organizing meetings with permission is also an effective way to bring people together; though it sounds contradictory, some schools may allow assemblies which address these types of issues if they are framed as educational discussions rather than protests or calls to action. 
Finally, social media can be used safely – and effectively – to spread awareness on many different kinds of issues affecting schools everywhere. Platforms like Twitter enable students to use their collective voice across town borders or between classrooms by using hash tags that symbolize the cause under discussion without having any repercussions from administrators. All said and done when dealing with raising awareness at school its best often start by having small initiatives with stealth campaigns first if necessary then build upon successes as you go!

You could set up an unauthorized gathering or activity during a lunch period or after school. Make sure to choose a location that is out of the way and where there are less people. Ask those who attend to keep the event confidential and respect that it is an unauthorized activity. Prepare some sort of presentation, activities or discussion topic related to the issue you want to raise awareness about, and try to make it fun and engaging. If you can, plan it in such a way that it appears as though everyone who attends is merely gathering for their own reasons, rather than part of an organized group protesting or raising awareness (it might help if everyone wears comfortable clothes). That way there will be less risk for any trouble. Be prepared also to handle any complaints from students or staff.
 
Finally, plan your gathering/activity accordingly: make sure everything goes smoothly but at the same time address any potential conflicts promptly without drawing too much attention from staff/students passing by/involved etc. Make sure also not to damage anything in the school premises.

Good luck! With careful planning and implementation I'm sure your gesture will create meaningful impacts regarding this issue you wish to draw attention onto.
 
Please also let me know how this worked out (if you agree).
