On November 17, The Students of Mrs. Steiniger’s Biology class from Cardinal Wuerl North Catholic arrived at the brand new Pittsburgh office of Bohler Engineering for a STEM Career tour all about sustainability. Bohler has been consulting on land development projects for a few decades now, and while not always demanded, they do consistently attempt to add as many green touches as possible to their projects.
After a look all around at the office space, including some employees very hard at work, the tour guide Micael Takacs took the students into a conference room for a look at some of the projects he personally had worked on. Mr. Takacs has worked on a number of sustainable projects in the area, including the Phipps Conservatory’s Center for Sustainable Landscapes, and the student’s very own Cardinal Wuerl North Catholic High School. Among the green innovations at both locations are clever systems for rainwater collection and reuse and rain gardens meant to prevent excess rain runoff. The students were very excited to learn that things they see every day have sustainable benefits that they were hitherto unaware of, and now can take on an entirely new meaning.
Mr. Takacs was also able to share knowledge of other sustainable projects of note and interest within the city, including a recently constructed building that can be opened up and cooled passively with natural air currents.
Bohler Engineering proved to be an excellent supplement to the sustainability education being provided by Mrs. Steiniger, and a great foundation upon which to continue building a bright sustainable future.
ovember 17th Mrs. Steiniger’s Biology class from Cardinal Wuerl North Catholic High School toured the Center For Sustainable Landscapes at Phipps Conservatory, as part of Sustainability Stem Career Tour. The Center For Sustainable Landscapes is one of the greenest buildings in the world, meeting the requirements of the Living Building Challenge the strictest classification for a green building project.
My name is Tim Roos, I’m a sophomore at North Catholic, and I recently went on the sustainability field trip at North. On the field trip, we stopped at the Oasis Farm Fishery in Homewood. The main topic of the tour as sustainability, and how Oasis has incorporated it into its function. Homewood is what is considered a food desert, which is an area that has no access to fresh fruits or vegetables.
ed sustainable agricultural practices such as aquaponics, but I know so much more now that I went to Oasis Farm Fishery. For instance, I didn’t know that you want the roots of plants to be white, which shows that there is a good amount of oxygen present. Oasis Fishery is using the most with what they’ve got. If the temperature becomes too hot in the greenhouse, they cover the sides with a metal-mesh cover, that reflects 50% of the sunlight and warmth, so the vegetables don’t fry to death. Every so often insects enter the greenhouse and eat away at the crops. Once Casey notices the insect problem, he will introduce a predator to the greenhouse. For example, if aphids are the problem, he would introduce ladybugs.
Fifteen students from Cardinal Wuerl North Catholic got the incredible opportunity to travel around the Pittsburgh area and learn first-hand about sustainability and engineering. We heard from many great minds in the fields of engineering and conservation. I was one of these students, and the whole day was eye-opening and I learned an incredible amount of important information. One of our stops involved going to Carnegie Mellon University in North Oakland to learn about what CMU does to be sustainable. Another purpose was to be educated on their engineering major, and how that class involves a lot of environmental engineering and learning about sustainable engineering.
First, we heard from Gwen Dipietro, the instructor of Introduction to Sustainable Engineering at Carnegie Mellon. She talked about her course and what the experiments her students due to preserve biodiversity and remain sustainability. She also talked about her research she completed in Pittsburgh. She researched the tugboats that move coal through the locks and dams of Pittsburgh. Her goal was to see how much coal went through these locks and dams as well as how often these transports occurred. Her teaching assistant, Genna Waldvogel, also spoke about her life as an engineer and how sustainability plays a large part in it. She discussed her research project to get her Masters Degree in Civil and Environmental Engineering. It involved the chemicals in the rivers of Pittsburgh and their possible toxicity. These instructors are great examples of sustainability in engineering and making a choice to try to be as sustainable as possible.
Andrea Rooney, the director of undergraduate programs in the department then spoke. She talked about a variety of topics, one of which being a project that her classes completed. It was all about exploring where each part of a product came from. She used the example of a water bottle and spoke about how the cap, wrapper and, even the ink all come from different places, increasing the carbon footprint needed to make the bottle. In her study, it was found that about six times the amount of water in a water bottle is needed to produce that water bottle. It was very interesting to hear all the seemingly nonexistent things that go into making a water bottle.
Discovering more about reproduction patterns. That’s what the students of the STEM Career Tour learned when they visited the Magee Women’s Research Institute. There, we were met by Dr. Judith Yanowitz who gave us a presentation on meiosis, and how our chromosomes are bonded during reproduction. Part of what Dr. Yanowitz studies is the reproduction and meiosis in microscopic worms, which so happen to have a very similar reproduction cycle that happens in humans. During our time there, Dr. Yanowitz took us to a lab and gave the students the opportunity to look under the microscopes and see the worms that she works with. Dr. Yanowitz also put some of the worms under an Ultraviolet light, which when exposed to the light, the worms move around quickly and you can see them moving under the microscope. 
Creating green everlasting power to sustain our future. That is the main goal of EverPower in their quest to create safer and cleaner energy through wind power. The STEM Career Tour recently took a visit to the Pittsburgh office of Everpower to see how wind energy works and how it can be used as alternative energy. The students were amazed to see how much information was presented on the 6 screens that were constantly gaining data from active wind turbines all throughout the country. There was also an active weather report on one screen that is used to see where winds will be heading and see where lightning is currently striking. Lightning is very important to the workers of EverPower because they need to notify their field crews when lightning is within in the area so they can evacuate working on their turbines and find a safe place to wait until the storm has passed.
