Comment on this resource
In this lesson, students will collect and graph data on air temperature, relative humidity, and dew point to observe why these variables change (or do not change) during the day. Graphs are constructed by using free downloadable software (WxScope). By making observations of qualitative and quantitative changes in these variables with time, they will understand the advantages of using dewpoint temperature as an indicator of moisture in the air, as well as the problems with using relative humidity as the indicator of moisture.
