How do you present chapters to a class in an interesting way?

I have to do a presentation at school on chapters 18-21 for To Kill A Mockingbird by Harper Lee. My teacher wants us to be the teacher for the period. She also wants us to be creative about it in some way. I have a few ideas, but they're pretty basic. I need to do something that will involve the class, and look at the major points, themes, whatever, of these chapters. Any ideas? Thank you.
