Student Nursing : Elderly Teaching Assignment?

I'm a student nurse, about to begin clinicals at a Senior Center. For a project, I am supposed to create an interactive and educational presentation, that is somewhat health related, and present to a group of seniors. Some groups are focusing on dental care (handing out trial toothbrushes/toothpaste) others are focusing on nutrition (showing the audience how to create easy, healthy meals),

So I'm short on ideas

.... any suggestions would be appreciated!
