Biography

Hello. My name is Dana Tsai and I am an experienced educator with a passion for helping making material meaningful and accessible for all students. I received my BS in Molecular Environmental Biology from UC Berkeley in 2008 and my Masters of Education from Colorado State University in 2015. I have five years of experience teaching high school math and science to a diverse group of students. This included finishing the 2019-2020 school year remotely, during which time I gained some experience creating screencasts to help my students through biology and chemistry content.

This year I am taking a break from teaching to stay home with my daughter who was born last year. I am very interested in the opportunity to stay active within education and to contribute my skills in communicating difficult subject matter to the Numerade community. While biology is where my focus has been most recently, I also have experience and a passion for teaching math.

Biology for AP Courses

The emergence of photosynthetic organisms is recorded in layers of sedimentary rock known as a banded iron formation. Dark-colored and iron-rich bands composed of hematite (Fe2O3) and magnetite (Fe3O4) only a few millimeters thick alternate with light-colored and
iron-poor shale or chert. Hematite and magnetite can form precipitates from water that has a high concentration of dissolved oxygen. Shale and chert can form under conditions that have high concentrations of carbonates (CO3 -2). These banded iron formations appeared 3.7
billion years ago (and became less common 1.8 billion years ago). Justify the claim that these sedimentary rock formations reveal early Earth conditions.
