I liked the group research component of this lesson plan. I also really enjoy the content of your design, it was very detailed and easy for the reader to follow. The topic is great! You will definitely hook the students with the comparison to their school.
There is good variety of instructional strategies and various ways of presentation including verbal and visual. The only thing I would suggest is research more tools they could use for presentation, or giving more choice to the students to get the desired information across to the class.
