Pringles under pressure

The students from Paulo Freire’s Downtown and University campuses are at SkySchool this week.

On the first day, we got to see a baby horned lizard on our hike near SkySchool campus at the summit of Mount Lemmon. We also spent ten minutes of silence on the mountain just observing the sounds.

We noticed that when we traveled from Tucson (3000’ elevation) to the summit of Mount Lemmon (9000’ elevation), a Pringles container expanded, and the lid domed up! We talked about why. The air pressure got lower as we went up the mountain, and the pressure inside the container stayed the same.
