“comparing the number of bacteria in eggs, meat, poultry, fish, or other foods. Samples are first weighed, then mixed with sufficient water to produce 1% solutions (1 gm/100 ml), and mixed thoroughly in a blender. Dilutions are assayed for total count. It is also possible to screen for the presence of certain pathogens (e.g. Salmonella) or fecal indicator organisms. “
Theoretical Laboratory Project in Microbiology (50 points)
General Guidelines
The goal for this project is to design a well thought-out laboratory experiment that you can carry out in a lab or even at home. You will develop the hypothesis, the method (design) for the experiment; a plan on how you are going to collect the data, possible outcomes, and conclusions. In short, you are going to develop everything that one needs for an experiment without actually testing it.
Please take a very close look at the rubric at the end of this document. It will help you to understand how I am going to grade you and what I am looking for in this assignment.
Since this is likely to be one of your first experiences in designing experiments that are not simply “cook-book” exercises, I have compiled a list of suggestions and guidelines that should help you to carry out this project successfully. Please read the following guidelines carefully, and spend some time planning your experiment accordingly.
The more focused your investigation is, the more likely you are to be successful in devising clear-cut experiments. For example, if you focus your experiments on answering the question “Do bacteria survive longer on cutting boards made of wood as opposed to plastic?”, you should be able to devise simple experiments that can clearly answer this question “yes” or “no”. On the other hand, if you focus on a more general question such as “How do bacteria survive?”, you will have a more difficult time deciding what experiments to do and how to carry them out.
Write a typed, well-constructed (complete sentences, proper grammar / spelling) lab report of your experiment.
¶ Include a reference section (as an additional page) with at least 4 citations including at least one published (journal or textbook) reference.
¶ Please submit your case studies through CANVAS using the Assignment tab. The deadline date is on the Canvas calendar online.
“Your instructor has incorporated the use of the Canvas-TurnItIn text matching service into this course. Your assignment(s) will be checked for potential plagiarism against Internet sources, academic journal articles, and the papers of other students in the TurnItIn database. TurnItIn generates a report that highlights any potentially unoriginal text in your paper. Students who take this course agree that all required papers submitted through TurnItIn will be added to the TurnItIn reference database. Students retain all ownership of the original intellectual property created in their written work.
Understand that results of the TurnItIn report may be used by Howard Community College in student conduct proceedings related to academic dishonesty.”
You will be graded based on the following rubric:

Creativity of the idea for an experiment
The idea is very creative and unique.
The idea is interesting.
The idea is not very creative.
Introduction
Summarizes relevant background information from textbooks, articles, your lab manual, etc.
Includes what a student is going to do, why he/she is performing the lab, what he/she hopes to gain from the exercise
and how this will be accomplished.
Some background information is summarized. Some important pieces of information are not included: what a student is going to do, why he/she is performing the lab, what he/she hopes to gain from the exercise
and how this will be accomplished.
Background information is not included.
Hypothesis
The purpose of the project is summarized in the hypothesis statement(s). The question(s) to
be answered is (are) clearly identified and stated using ‘if…then’
statement(s).
The purpose of the project is summarized but not as a hypothesis statement.
No hypothesis.
Methods
Clearly explains the design of the experiment. Procedures are listed in clear steps. Each step is numbered and is a complete sentence.
The design of the experiment is somewhat confusing.
The design of the experiment is not though-out and/or impossible to perform.
Possible outcomes
The possible outcomes are clearly stated and conclusion is made based on the possible outcome.
The possible outcomes are clearly stated , but no conclusion is made.
No possible outcomes and no conclusions are made.
Applications/Further questions
Describes how the results answer the question (or not). Summary describes the skills
learned, the information learned and some future applications to real life situations as well as further questions that need to be answered.
Describes how the results answer the question. But no further questions are asked.
Does not describe how the results answer the questions.
Appearance/Organization
Final report is typed and uses headings to visually organize the material.
Introduction, Hypothesis, methods, possible outcomes, application and further questions are bolded heading in the report
Final report is typed, but lacks organization.
Not typed/submitted online
Spelling, Punctuation and
Grammar
One or fewer errors in spelling, punctuation and grammar in the report. Scientific names
must be properly formatted.
Three or four errors in spelling, punctuation and grammar in the report.
More than 10 errors in spelling, punctuation and grammar in the report.
Works Cited
Any information that is not student’s is cited. The quotation marks are used for direct quotes. In-text citations are used when information is paraphrased. Comments about the reliability of the sources are made.
No in-text citations or reliability comments.
No in-text citations or references.
Safety
The project talks about safety and safety procedures. The design of the
experiment posed no safety threat to any individual.
The design of the
experiment may pose some safety threat to an individual.
No safety procedures are mentioned.
