Testing
UV Protection
- Sunprint
Paper Test
- Requires
Exposing to UV
- Natural
Source of UV: Sun
- Clouds
and Precipitation Block UV from Ground
- Variable
so affects experiments during class
- Create

while providing structure for controlled experiments
- Inexpensive
- Total Cost = $3-5, Relatively Easy to Build, Relatively
Rugged
- Provides
Opportunity to Run Experiment Any Time
- Allows
Students Develop Controlled
Experiments Quickly and Easily
