My idea for the global presentation was to share to the kids the stories about the brazilian folklore at the local library. I showed to them pictures of the most famous characters and their stories and then we made a mask representing the brazilian werewolf, they loved it.
For volunteering I helped in the garden at the Baker School during the summer helping watering the plants etc, the kids were involved in a project to build and keep a strawberry tower.  I was happy to help them in this project.
