i think it does work for 9th graders to do this project.that way they get to know each other better.i also think it did gave an effect on the students because they got to know each other a bit more.if this activity invloved the 10th and 11th graders i think it will be better because in the future they would probbably do better.if the activity continued for the rest of the year it might get boring because the angel might run out of ideas to do to their chosen one unless they switch once in a while.then on i think this project is good for all grades.
