This lab introduced the idea of dew point, relative humidity, and heat index. The dew point temperature is measured, then compared to a calculated value based on the relative humidity. It has nothing whatsoever to do with dew-covered insects, but it's pretty amazing photography, don't you think?
Student Objectives
- Define the idea of relative humidity
- Experimentally determine the dew point
- Calculate the dew point from the relative humidity
- Compare the the measured and calculated dew point values
- Relate the relative humidity to the heat index
