Science fair is a bit of a family affair in our house. Carolyn brings us her questions, we brainstorm potential experiments, and then we work on it together.
This year, carolyn decided she wanted to learn about "temperature inversions" a weather phenomemon we experience in the winter as a result of living at the bottom of a bowl (we have a dense population surrounded by mountains on all sides). When we have an inversion, air quality is bad. All of our emissions get stuck under the inversion layer. In fact, salt lake city has held the title of poorest air quality on some of our worst inversion days.
While we may have learned about convection in science class -- and while we commonly know the adage "warm air rises, cold air sinks" -- it was fascinating to see the experiment she did. It really helped me understand this unique weather phenomenon that makes us in salt lake city so aware of our emissions.
