I was recently reading the September/October 2022 issue of "Science & Children" a publication of the National Science Teaching Association.  In this issue, I read the Science 101 column, written by Matt Bobrowsky.  He wrote a column entitled, "Do You Have a Weather-Related Activity That My Students Would Enjoy?"   In this column, Matt addressed two topics:  Air Pressure and Barometers.  This leads me to do a two-part podcast series.  This podcast will look at the topic of air pressure and how it can be explained to students and the next podcast will deal with tool that measures air pressure - barometers.  Air pressure is the force exerted by air on any surface in contact with it.
