1. INVESTIGATION : The Path of Light From Air into Acrylic In groups of 3, decide who will be the MATERIAL manager, TASK manager, and SAFETY officer. Every person must have a role. Material manager: responsible for getting all the material and for cleaning up. Task manager: responsible for becoming familiar with the procedure, and knowing what the group members have to do (step by step). Safety officer and recorder: responsible for any safety issues, and for recording the measurements for their group. In your groups, fill out Table 1 on your handout and answer questions # a to i on a separate piece of paper. To be handed in by tomorrow’s class. On your question sheet, please write down the names of your group members and their responsibilities. 11.1 Refraction of Light
