This is a cool lesson plan because it involves students making a case for something by using research and evidence. The lesson is also good because it give students choices on how they wish to present their understanding. Also, students get to collaborate with other students on the project.
One suggestion to further guide the students technologically would be to make the assignment a WebQuest. That way students would be more guided in their search for information on the internet and they could have access to other materials in the WebQuest.
