Today we went to Dr. Griffiths lab on UNC campus and heard some scientists who work in the lab, speak about some of the work that they have been doing. These speakers tried to relate what they were studying in the labs, to what we were learning in class so we had a basic understanding of what they were talking about. During this presentation, they displayed some photos of DNA and mitochondria. We learned about how these scientists prepared the cells for viewing under the microscope, as well as where they cut the cells. After the presentation was over, we all went upstairs to the few labs under Dr. Griffith’s name. There, the scientists showed us two of their Electron microscopes and let us use them to observe the different organelles in some bacteria. We saw firsthand how these electron microscopes had evolved over the years as new technology was introduced. One of the scientists demonstrated the process for cutting the cells under a microscope and Dr. Griffith showed us one of the microscopes that he built himself.
