Bacteria Virtual Identification Lab Report

Bacteria Virtual Identification Lab Report

Question Description

I’m working on a biology report and need a sample draft to help me study.

This lab report is based on the bacterial identification virtual lab from HHMI.

Complete the lab assignment which is based on identifying a bacterial species in the first sample. Read instructions below first so you’ll know what to do as you perform the procedure/write your report. You will submit two items: the lab assignment document and the lab report based on the assignment.

In-text citations, references, and your title page must be in APA (7th ed.) style. Refer to this link or your RCCC library for help: Purdue Online Writing Lab Guide for APA Style

Title Page: worth 20 percent

The title states the focus of your experiment. It should be descriptive, accurate, and concise. Include the title, your name and the institutional affiliation. Text placement/position on page should be done according to APA style (see above).

Introduction: worth 20 percent

The introduction should include adequate background information on the topic and should include in-text citations (in APA style) from at least 4 relevant sources from scientific databases. If you are considering citing any sources that are not from a scientific database, you MUST obtain approval from your instructor FIRST Do not wait until the day it is due to ask about this! Your introduction must also state the purpose of the experiment, and it must include a hypothesis that is based on research and/or sound reasoning. In this case, your hypothesis will be an educated guess of what bacterial species is in your sample. Your choices are (Escherichia coli, Salmonella typhimurium, Bartonella henselae, Brucella canis). The only information you have at the start is the type of sample collected. Do a bit of brief research about the FOUR bacteria choices and find out what types seem to match best with the scenario, then make your hypothesis. Remember, if your hypothesis ends up being rejected, that is neither ‘good’ nor ‘bad’ and does not harm your grade. Finally, be sure to include a brief statement about how you intend to test your hypothesis.

Materials and Methods: worth 20 percent

This is a thorough account of the materials used and the methods you followed. Include enough details that someone else could perform the experiment. The section should be written in passive voice. Do not write this as a series of commands, and do not write “I did this, then I did that.” For example, do not write “Make sure to add 5 microliters of the solution to the tube.” Instead, write like this: “5 microliters of the solution were added to the tube.” If this is unclear, ask your instructor or get help at the RCCC Writing Center.

Results: worth 10 percent

In this section, include all tabulated data and data trends from the experiment. In this case, your data will include the DNA sequence from the sample and the results list from the BLAST database. An example of a trend in data would be if you notice a particular genus or species occurring more frequently in the BLAST results. You will need to paste screenshots/snips of these items into the report and then add a caption for each. In addition to showing the results in a chart or other visual format, you must include a written account of the results. For most students, this will take about 1-2 paragraphs.

Discussion and Conclusions: worth 10 percent

While your results section simply states the data and trends, this section is where you discuss what those numbers/results might actually mean. Summarize what happened in your experiment. Reflect on the data from the results section. State your conclusions and back them up with the data from your experiment. Your conclusions should be specific enough that they state whether you are rejecting or accepting your hypothesis based on the data. Discuss the real world applications of the experiment. Also, include discussion of any errors you feel were made. Do not be afraid to talk about your mistakes; this is part of the scientific process and nothing to be ashamed of! What could be improved if this experiment were repeated?

References Page: worth 20 percent

The references should occupy their own page at the end of the paper. They should be in APA style. These are the references for sources you cited in text in the introduction. Your lab manual is NOT an acceptable source to cite, nor is Wikipedia, Quora,, etc. Use peer-reviewed literature (from scientific databases).
