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 Refraction of Light
