Meet Gustav

Personal Photo

Please excuse the shot glasses

For an ongoing class lab, we are each growing our own sunflowers in cups. These sunflowers will ultimately be transplanted into a community garden near campus because they are thought to remove lead from the soil. Since our community garden is located in an urban area, it possibly contains lead as a result of many years of vehicle pollution. 

I think Gustav (my sunflower) was a late bloomer and I thought I was going to have to  get another seed. When I left for a debate trip on February 19th, he still had not sprouted and just looked like an empty cup. I came home to this after the trip! 

I have been watering Gustav faithfully and leaving him where he can get some sunlight during the day. As of today, Gustav measures eighteen inches tall! 

Windrose Plots

These windrose plots are from the four seasons of 1992 in Nashville, Tennessee. I was born in Nashville during this year.

Here is an aerial view of the Nashville International Airport:

From these graphs, we can see that seasons have a massive impact on the wind speed and direction. On August 27 of this year, three F0 tornadoes touched down in Middle Tennessee, which could have impacted the data in the summer section. 

Solar Trajectory Lab

In this lab, I determined the trajectory of the sun by using an 8 inch stick, the length of its shadow, and the direction of the shadow cast. 

Rainfall in Willet Science Center Parking Lot

For last week's lab, we calculated how many gallons of rainwater fall on the Willet Sciene Center parking lot during a 2 inch rainstorm. This type of calculation could be important to determining how to best construct a parking lot for optimum drainage of stormwater. A space that is designed so that water that accumulates quickly stagnates instead of drains can breed pests like mosquitoes or even cause a flood hazard during a big rainstorm. This is actually a pretty big concern on campus when it rains. 

This is a photo I took last year by the Adams-Winship Apartments after a rainstorm. Although it is difficult to tell from the darkness of the picture, the water had created a small pool about nine feet across and probably six inches deep in some places. The pool extended from the improperly drained parking lot. 

Rachel Carson: A Short Biography

“Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is something infinitely healing in the repeated refrains of nature -- the assurance that dawn comes after night, and spring after winter.” 

― Rachel Carson, Silent Spring

Rachel Carson lived from 1907 to 1964. She grew up in Maryland, attended college, and ultimately earned her MA in zoology from Johns Hopkins during a time where few women were achieving any sort of higher education. Her work in the environmental science field began as a writer for the U.S. Bureau of Fisheries. She was the second woman ever to be hired by the organization. Eventually, she published several works designed to increase interest and awareness in the environment, including The Sea Around Us, which won the 1952 National Book Award for Nonfiction and launched her into the academic and public eye as a respected conservationist. 

Her most famous book was Silent Spring, which challenged the use of pesticides. Many credit the book with launching the environmental movement because it was so widely read by the public. The book was also one of the first widely-read pieces to illustrate the links between pesticides with cancer and other health problems in humans. Much of its focus was on DDT, a pesticide that was ultimately banned by the EPA. 

Rachel Carson died from breast cancer in 1964. She received a posthumous Presidential Medal of Freedom from Jimmy Carter. In 2010, she was recognized by Time Magazine as one of the top 25 Most Powerful Women of the Past Century.
