Need collaborative lesson plan ideas

Hi,

I am hoping that someone can help me with some ideas for a collaborative lesson plan that I am developing. The lesson is mainly for U.S. history high school classes. The lesson is focused on the attack on Pearl Harbor and the underlying values of citizenship that are embedded in people's experience of the event.

I have created this outline to show the learning objectives and resources available: http://www.goforbroke.org/learning/digitalcurriculum/lesson04/lesso.... What I would like to develop is a group activity along with assessment that utilizes the video clips. Any ideas would be much appreciated.

Thank you!
