1.2. Basic index of refraction determination
type lab using the substances we will be
using for the total internal reflection
gelatin lab. Students have already
calculated values and they can anticipate
layering, etc.

Practice
Jell-O Activity
Materials needed:
Directions:
Teacher makes Jell-O molds in advance.
Small student groups (number of
available laser pens dependent)

2. Short Essay/Closure:
• Relate the movie, SPRi, to the Jell-O
activity
Watch the movie and write a well-constructed
paragraph contrasting / comparing the
nanoscale equipment technique to the
macroscale gelatin model.
