Writing Questionnaires (Bad Questionnaire Starter)

I started the lesson by just handing out a terrible questionnaire on the eating habits of teenagers as if I was collecting data (The class were outraged). They discovered the problems and then in groups wrote rules for writing a good questionnaire. The mid section of the lesson was using the textbook but then for a plenary they rewrote the bad questionnaire. I found the bad questionnaire starter on here from another tes uplaoder and adapted it to suit.The 'Eating Habits of Teenagers' is A5 size
