Help! Student Nurse needs Geri Teaching ideas!?

I'm a student nurse, about to begin clinicals at a Senior Center. For a project, I am supposed to create a fun, 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!
--------------------
I don't know what the health of the residents is at the Senior Center, but how about a game of "Simon Says" involving safe and purposeful movements for exercise? Such as, "Simon Says do arm circles." Of course, you would demonstrate what they should do along with them. At the end of the game, you could give a short teaching lesson about the benefits of simple exercises such as the ones you just did.
