Use this as a template for your students to fill out during the last week of school. Have them bring in a Forever Stamp and an envelope (and their address--even 7th graders aren't always sure)--and you've got a fun activity. (You just have to remember to mail them out during their senior year.)
Questions are fun for them to answer: Some short and sweet, some more open-ended.
Set for "7th grade," you can easily find/replace and change it to any grade.
