As part of my adventure in moving to Utah, one of the things I’ve been doing is working on getting my Utah teaching license. Education is a state power, so every state licenses differently. And oh boy, do they do it differently.
In Colorado, I hold a secondary science teaching license. This means, according to the state of Colorado, that I am qualified to teach any science class from grade 7 to grade 12. Colorado had a series of requirements I needed in order to get this license; I needed to have a bachelor’s in a science, six credits plus a lab class in the other two core sciences (since my bachelor’s was in biology, the other two core sciences for me were chemistry and physics), an earth science class, an astronomy class, and a certain number of credits. I needed a passing score on the general science Praxis exam, and a certain number of education credits along with student teaching.
Utah, on the other hand, licenses by discipline. When I receive a secondary science license, I must also apply for endorsements for each type of science. For example, I am working on getting my biology, chemistry, environmental, and earth science endorsements. Utah has a list of college classes required for each endorsement, and each endorsement also requires its own specific Praxis test. Amusingly, the only endorsement I actually had all the classes for was chemistry! Because my major was in molecular biology, I was missing several crucial “big bio” classes.
In order to remedy all of these missing pieces, I’ve been diving into AP bio study sessions with Mom to prepare for the biology Praxis (she was highly successful in preparing me!) and taking several online courses. The first of these courses was Oceanography.
To be totally honest, it’s been awesome to go back to being a student again! There’s something very satisfying about having a reading assignment (this week was FIVE chapters, which was a bit much…) and a three page paper to write. I will admit to having the same problem with word limits that I’ve always had – I write three to four times more than I have space for and then have to cut things out.
And I’ve been learning interesting things! My favorite so far has been learning about global wind patterns; I now know what the trade winds are and why they go the direction they do, and why sailors warn against westerlies. These winds drive many of the ocean currents; I can now explain why Uppsala, Sweden has a climate similar to Colorado (but wetter) even though it’s so much farther north. (It’s because the Gulf Stream moves masses of warm air that direction.) And I’ve learned that if you ever need to explain why air or water is moving in a circular or spiraling motion on a global scale, or just explain why anything isn’t behaving as linearly as you thought, the answer is the Coriolis effect.
If you think about the Earth, the most solar radiation happens at the equator. That means that air gets warm and rises. Then it pushes out towards the poles, drops a lot of precipitation, and falls back down as cool dry air. If you look at the Earth, you can see the hot wet equator is bounded on either side by deserts; the deserts are where the cold dry air falls back down.
However, the Earth is spinning. This is the basis of the Coriolis effect. Imagine if you launched a rocket from Quito, Ecuador (at the equator). Even if you launched it straight north, the Earth would spin underneath it while it was flying. The rocket would land northwest of Quito. There’s all sorts of math you can do to figure out exactly how far west, but I haven’t gotten that in-depth.
The Coriolis effect means that the warm air rising from the equator falls back down to the west of where it started, either northwest or southwest. These are the trade winds. The next convection cell away from the equator, either north or south, blows to the east (these are the westerlies!). And now when I read novels, I actually know what these things mean!
(The lead image explains it nicely, too, if you like images better than words.)
I still have oceanography homework due today, so I’ll leave this one here and give you your homework! What’s the best new thing you’ve learned lately? You can define “best” however you like.
Actually, a post script. The first new thing I learned this year was “awkward salmon.” Remember awkward turtle? You put your hands on top of each other and circled your thumbs in awkward situations when no one knew what to say. It was an awkward turtle because it only had two legs. This spawned all sorts of awkward animals and plants…all the way to awkward palm tree. But when my brother put his hand between my arm and my rib cage and flapped it back and forth, that was a new one to me. That’s awkward salmon. Cheers, Jeff, for teaching me that on our New Year’s hike.
