Analysis
The project was full of successes and defeats. At the end of the project I felt confident that I could properly administer all of the methods when called apon.
The following is a list of things that went wrong and what occurred because of thes:
-the first agar dish was littered with jabbing holes due to inexperienced inoculation loop use. The dish was replaced and the second dish was correctly streaked.
-The first dish was contaminated. The first dish may have been contaminated on any of the many times that the dish was opened accidentally and by at first not being able to maneuver the inoculating loop with the lid so close.
-The second dish was also contaminated by fungus. The fungus did not touch any of the tested bacteria cultures, but due to it ending up taking up nearly the whole dish, there is a very good probability of the fungus affecting the observations of the bacteria cultures.
The use of slightly hazardous pathogens would have made the lab more interesting. I found that Requirement #3 was impossible due to the fact that we were not instructed on how to take the readings and since the soil was immediately disposed of, impossible to do afterwards. More instruction is definitely not needed. All of the procedures were well explained and I at no point found myself in dire need of interpretation of the procedure.
