Relative Humidity and Dew Point Lab
In this Earth Science Lab, students will gain an understanding of what relative humidity and dew point are. There are four parts to the lab. The first part will help them understand the relationship between the ability to evaporate and humidity. Students will then use psychrometers to determine the humidity outside as well as inside. They will calculate the wet-bulb depression and then use the relative humidity chart to determine the percent of water in the air outside and inside the classroom.
