Ideas Needed!

I am subbing in Middle School Social Studies tomorrow.  I am brainstorming a backup lesson plan in case I need one.  Any ideas?  I was thinking of having the students use index cards and list 3 things they enjoyed learning about in Social Studies, 2 things they would like to learn more about, and 1 thing they found uninteresting/1 thing they did not learn but would like to learn.  Another idea is to have them write about a current event that took place during this school year that they found interesting (i.e. anything in the news).  My last idea is to have them write a letter to the incoming students to give them advice on how to do their best in Social Studies class in the upcoming 2012-2013 school year.  I thought about also letting them make a time capsule that they can collect next year.  The time capsule would describe them, what classes they like, type of music they like, what they thought was the most interesting thing they learned in school this year, etc. Maybe they can make predictions about the upcoming school year.

I would love any other creative ideas.
