11.1 Refraction of Light
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.
