Barometers

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 lead me to do a two-part podcast series. The previous podcast looked at the topic of air pressure and how it can be explained to students and this podcast will deal with the tool that measures air pressure - barometers. The air that surrounds us and surrounds the Earth is called air pressure. So, the pressure in the air surrounding us is called atmospheric pressure. An instrument for measuring atmospheric pressure is called a barometer.
