Lexi Cohen's STEM Portfolio
Welcome to my STEM portfolio. I am a member of the class of 2016 at Roland Park
Country School, where I actively partcipate in the STEM program. I truly
enjoy the sciences. Due to my interests in the sciences, in sophmore year, I
took honors physics and honors chemistry. After realizing my love for chemistry,
I decided to embark on AP chemistry during my junior year. I found interest in
the labs and enjoyed discovering the makeup of the world on a molecular level.
Joining the STEM institute my freshman year was a smart deicision for me as the extra classes in science, technology, engeneering, and math furthered my curiosity in these subjects. I also participated in a summer program, ESSRE (Environmental summer research experience for young women). One of my first projects in my STEM classes, was creating a test on Scratch Program to determine what the effect of flashing lights is on short term memory. In case your computer does not have scratch downloaded, below is a screenshot of my program. I also wrote a paper on this project, which can be seen in my links. Second semester of my first year of STEM, I worked on an egg drop project, which also culimanted in a final paper. During my sophmore year, we first started working with the scratch program again, and my project for that can also be seen below. We also learned about Euclydian Gemometry and wrote a paper on the different types of geometry. To end the 1st semester, I worked with some classmates to create a project on the topic of opitcal illusions. Throughout second semester, we tried to find the most efficient way to package a bottle of sunscreen. We made a powerpoint about the materials we chose and did an impact study to show our progress with the package.
For my 11th grade long term internship, I am working with Katrina Ferrara and Barbara Landau on thier study of Williams Syndrome at Johns Hopkins University. I am specifically looking at the episodic autobiographical memory of people with Williams Syndrome compared to that of typically developing people to discover any differences.
