Audience Participation Ideas for Divorce and Separation Presentation?

[Nice to meet you]

I am doing a presentation in college on separation and divorce. I am trying to think of any ways I could include my audience outside of them asking me questions at the end.

Here are some specifics:

-It is an adult audience (college kids and a professor)

-I'd like to refrain from asking very personal questions as the topic may be too involved for some people

-The audience participation is a required element of the presentation and it needs to be relevant to the topic.

Any ideas would be appreciated thank you!
