I may have the student create a survey discussing difference and similarities of their lives.Before they start obtain a group of classifications from the class, ex gender, ethnic, interest - academic and non academic, goals, educational future..... I would put students in groups of 3 or 4. Each group will create 5 questions in the first 30 minutes of class. After the groups have done their list, We will discuss each list with the group and decide on a final list - one from each group. Number of questions would be determined by the number of groups.
We can take this final survey to other students/teachers in the school and discuss the outcome in a future class.
