Where can I find a Kid-Friendly article to teach about deafness/deaf culture?

This week in my second grade cl we are reading a story about a cl of students who are deaf who go to a concert. As one of my activities for the week I want to have the kids make an informational brochure about deafness/deaf culture. My problem is that I can't seem to find any articles simple enough and short enough for them to read on their own. Does anybody have suggestions of where I can find something? Thanks!
