2. Conclusion:

2.1: Description of what you learned in this lab In this lab, students dissected a pig kidney to deepen their understanding of the excretory system and the role of the kidney within this system. The students were able to tie in their learning from classroom discussions and textbook work into a first-hand learning experience with a pig kidney. This hands-on learning experience in the laboratory made it easier for students to be fully engaged. They were able to see, touch and explore the pig kidney. This helps each individual have a better understanding of each structure of the kidney as well as their functions, resulting in a better understanding of how the organ works. Also, this greater knowledge of the excretory system in a pig can be translated to the human body. The individuals were able to make comparisons of this dissected pig kidney to a human kidney, leading to students holding a stronger grasp on the human excretory system. Not only did this lab help the students understand the kidneys parts and functions, but also helped the students gain laboratory and dissection skills. This dissection was the first for many students, but every individual was given this opportunity to learn how to properly use new tools, and how to properly cut into this organ with care and precision. These new skills will become very beneficial for other labs in the future. 2.2 Assessment of viability of experiment and comments on improvement of experiment Identified Sources of Error Butcher cut in pig kidney: Some of the students had a cut made by the butcher in the pig kidney. This cut could decrease accurate visibility of the kidney and its inner structures. As well as damaging the inner structures, which also makes it more difficult for the structures to be distinguished and looked at. Softness of Tissue of pig kidney: Due to the freshness of the pig kidney, the tissue was very soft. This made it difficult to cut into the tissue carefully and precisely. Therefore, resulting in jagged cuts that did not maximize the visibility of the inside structures of the pig kidney. Non-inclusion of ureter & adrenal gland: When the pig kidneys were cut, the adrenal glad was removed and the ureter was cut very high. If the adrenal gland was present, and the ureter was longer, it would make it more efficient to examine those structures.

Improvements for Sources of Error To improve this error, it would be recommended that the butcher is more careful when butchering the pig, or removing the kidney. This would ensure that the kidney is not damaged at all. As well as decrease the chances of damages to the inner structure of the pig kidney or decreases in visibility during the laboratory. To improve this error would be to dissect a preserved kidney. This would result in a stiffer kidney, where the students could make cleaner, more precise cuts. Therefore, having a better image of the pig kidney and its inner structures. To improve this error, it would be recommended that the butcher cut lower down on the ureter to increase its visible presence, as well as include the adrenal gland. This would allow the students to have an even better understanding of the kidney and the excretion system....
