I'm trying to get my head around how to deal with model release forms for an event I've volunteered for.

I've been requested to take photographs of children for a holiday club during the term 2 school holidays and the photos will be used for a presentation for the kids and parents at the end of each day and possibly for advertising for future holiday programs.

I understand that I will need to get the parent/guardian of the child to sign a model release, but what exactly should the release include as everyone involved in the program is volunteering and there is no cost for the child to attend.

Are there any suitable examples that I can use or modify?

If I understand correctly, the parents will retain copyright unless otherwise stated in the model release which I think is OK, as long as I and the not for profit organisation running the program can use the photos as they see fit.

Thanks!
