Asking Questions - variety of texts

Here are some of the questions the class came up with as we watched the video. Who can explain the difference between thin and thick questions?

THIN QUESTIONS	THICK QUESTIONS
·         what is she reading ·         what did he steal? ·         who paid the bill? ·         why did the man pass out? ·         who paid off the medical form? ·         what's wrong with the mother? ·         is the doctor the boy?	·         why did the man pay for the medicine? ·         why did he steal the medicine? ·         why is it (medicine) so important? ·         why did the man help the boy? ·         why didn't the boy thank the man? ·         why don't more people help like this?

Is the boy poor? - is this a thick or thin question?
