1st Semester Labs

Lab 2b: Characteristics of Model Organisms-

During this lab we experimented to see which of the three model organisms (E. Coli, Aspergillis niger, and baker's yeast) grew the most in different temperatures. The important biotech skill that we learned during this lab was Z-streaking; this maneuver is crucial for growing organisms on a plate. It involves spreading the cells of the organism that you are trying to grow over the plate by first Z-streaking 1/3 of the plate, heating the stick to remove extra cells, cool the stick, rotate the plate 90 degrees and Z-streak again starting from the tail of your previous streak, repeat. This skill will help in science classes because I am now able to correctly grow organisms on a plate for the best results. We worked together well as a team by making sure that everyone was understanding what was going on and why it was happening before moving on to the next thing. Something that I could improve on is the z-streaking because when I streaked the plate the organism grew to far out and not in individual clusters, I think this is because of too much pressure when applying the cells. During the lab, I demonstrated growth in Critical Thinking and Collaboration. In terms of Critical Thinking, I worked on the skill of Z-streaking, understanding its importance in growing organisms effectively on a plate for optimal results. Additionally, in Collaboration, our team worked great together by ensuring everyone understood the procedures before progressing.

Lab 2c: Using a Compound Microscope to Study Cells

During this lab we took an in depth look at cells from different plants, animals, and objects. The skills that we took away from this lab was a deeper understanding of how to effectively use a microscope to look at cells from a small magnification. This skill of knowing how to use a microscope will be useful for further science classes because it is a basic skill that could be brought up at any time in a science class. During this lab I did well with learning how the microscope worked and how to adjust it so that there is a clear picture coming through in the scope. Something that I did well as a team member was teaching my table mates how to use the microscope if they could not get it in focus. I could improve on this skill by spending more time looking at things under a microscope to get some more practice using it. I could improve as a team member by going and getting the supplies that are needed for the lab and not just sitting at the table.  In this lab, I developed my skills in Conscientious Learning and Collaboration. I gained a deeper understanding of using a microscope effectively, ensuring clear images at small magnifications. Also, in Collaboration, I did well in guiding my table mates on microscope usage, helping create a supportive team dynamic.
