Uh, what are we working on?ANSWER:You are going to work on being a scientist!Discuss with your neighbors what interests you about science.Then, together define “scientist”.ACTIVITY:One ONE piece of paper, write your name and the name of your neighbor with whom you will work on this exercise.Now, working with your neighbor, write down what you think are attributes of a good scientist. Write your list of attributes on the left hand side of a piece of paper.FOLD THE PAPER IN HALF DOWN THE MIDDLE AND TURN IT OVER.NEXT TASK:Working with your neighbor, write down what you think are attributes of a good student of science. Write your list of attributes on the right hand side of a piece of paper (the one that is facing up).NEXT TASK:Open the sheet of paper and compare the lists. Identify common attributes by circling
