If you were doing some type of Heritage or Family History project with your students, and wanted them to produce a powerpoint, this is a decent sample for high school level. It has pretty neat animations and covers the students grandparents, country of origins, ethnicity breakdown, religious affiliations, etc. It's not real long, but it's pretty polished. I used it as part of a project for sophomores entitled: "Where I'm From, Where I'm Going" that was designed to help with cultural awareness among sophomores. I also had them interview a relative who'd immigrated here. Resources from teachingtolerance.org were helpful in this.
