Patrick Henry High School Ecology Students Study Air Pollution

Three boys hold two bottles together.Students in Ms. Eason's Ecology class have been studying air pollution.  As part of their unit, they researched past air pollution disasters and inversion layers.

An inversion layer is a layer of the atmosphere in which there is a temperature inversion, with a warmer layer preventing the air below it from rising, thus trapping any pollutants that are present.  Students performed an experiment using warm and cold water and food coloring to demonstrate a temperature inversion.  This experiment gave the students an excellent visual of how convection currents work and the impact that the inversion layer has on trapping pollutants.
