Each of you need to write the following: _________________________________________ Write down three observations- things that you can actually see that you believe are very important to the picture you are viewing. Write down three inferences- things that you suppose are likely to happen based on what you see in the picture. _________________________________________ Your observations and inferences do NOT have to be the same as your partner.
