What is a lab report?
One of the most critical, yet ignore aspects in scientific fields is proper scientific writing. Here, the student’s ability to accurately communicate research findings is important for their academic performance in the biological and physical sciences. Science is a generally communal field, where researchers develop ideas and look for ways to communicate and convince others in the scientific community of the validity of those ideas. As such, learning how to communicate your research findings and scientific ideas effectively is a critical skill. As scientists and students are often judged based on the frequency and quality of their writing, students require a solid foundation on how to develop stellar lab reports. Students

The report is written to describe as well as analyze a lab experiment, which explores a scientific concept. When writing a lab report, it is important to ensure that the discussion of the procedures, objectives and results is conducted in a way that is specific enough to allow those interested to replicate the experiment.
An important reminder here is that lab reports make it difficult for students to rely on a single explanation for the findings. As such. It is important for students to seek as many possible relevant and potential interpretations as possible. Even in the event that your findings fail to support your hypothesis, the findings are still of value as you could prove that, within the contextual limitations of your research, your argument was not reliable. You could then go ahead to consider other alternative areas for

First, you need to define the purpose of the paper, which includes making sure that you have read and understood the instructions. Part of the planning also includes gathering information that will be used to support arguments in your report. Make sure to note the details of the sources you consult in your research, including the currency or the source, any potential bias, and the authorship. This information will facilitate the citation process and the creation of a reference list.
An important consideration when looking to write a quality lab report is the structure. While most lab reports include the sections outlined below, there are disciplines and experiments that will require variations in the format. It helps to tailor your lab report according to the requirements and properties of the specific experiment. Nonetheless, the main parts of a lab report include:
• A succinct
The unknown bacterium that was handed out by the professor labeled “E19” was an irregular and raised shaped bacteria with a smooth texture and it had a white creamy color. The slant growth pattern was filiform and there was a turbid growth in the broth. After all the tests were complete and the results were compared the unknown bacterium was defined as Shigella sonnei. The results that narrowed it down the most were the gram stain, the lactose fermentation test, the citrate utilization test and the indole test. The results for each of the tests performed are listed in Table 1.1 below.

Writing in Biology is different than writing in other courses like English. In Biology, the writer must conduct an experiment prior to writing a lab report on the findings. For this lab report, I had to conduct an experiment comparing the cellular respiration rates of germinating peas and non-germinating peas. Before beginning the experiment, we had to create a thesis that would state which set of peas would have the higher respiration rate, germinated or non-germinated peas. We were expected to make a thesis based on our prior knowledge of how cellular respiration works in plants. I conducted the experiment during class two weeks before the lab report was due. The experiment consisted of placing peas in a Biochamber where the levels of carbon dioxide and oxygen would be measured every 6 seconds for 3 minutes. After completing that, my instructor stressed that we repeat the experiment 5 more times for each set of peas. After collecting the data, we compare...
First you need to decide what form your paper is going to take, then decide what the topic will be about. I decided to do a rhetorical analysis of a song, which I knew very well. Then thought what I could do with the lyrics to make it into a paper that people would
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.

In conclusion, the title and context of the article are clear, and appropriately match the hypothesis of the authors. There is consistency between the objective of the experiment and its relationship to science. This writer found some issues in the overall presentation of information, in that the text lacks smooth transition, and was difficult to read and follow.
Using your finger, gently tap the tubes to mix the Luria broth with the cell suspension. The test tubes will need to rest for approximately five to fifteen minutes in a room temperature environment.
In this experiment my lab partner and I collected an unknown sample (sample A) and performed a series of tests and analyses to determine the chemical composition of the unknown. One of our learning goals was to practice performing the basics of analyzing an unknown; this entails measuring boiling point, melting point, and noting its physical properties (color, smell, etc.) In addition to this, we also practiced reading basic spectra, looking at and interpreting test results, synthesizing derivatives of our unknown, and testing the melting point of said derivatives to help us further identify our unknown.
The laboratory experiment gives the experimenter a greater chance to control the conditions and enables you to measure behaviour with greater precision. This method also allows for quantative research and also enables greater control of variables. Although it gives the experimenter greater control, this can also seem daunting to the subject who may feel more uncomfortable and is less likely to ...
In the investigation I carried out a chemical reaction occurred. A chemical reaction is when two substances collide with ... ... middle of paper ... ... he volume of the Hydrochloric acid that can be reacted with the Sodium Thiosulphate. I would change these things in order to compare the results between the two different investigations and also to observe what difference different concentrations make on both investigations.
First we placed the slide under the simple microscope and observed it at ten times magnification level. We each took turns looking. We then copied them as drawings into our Cornell notebooks. After that we changed the magnification to fifty times and observed the slide. We each took turns looking. We then copied what we saw into our Cornell notebooks. After that we changed the magnification level to sixty times and we each took turns looking at the slide. We then copied what we saw into our Cornell notebooks and sat down together. When we were all done drawing we spoke about what we seen and gave each other ideas on how to write our Lab Reports.
It is mandatory that all the lab users need to work under the supervision of the instructor or any other qualified personnel. When conducting experiments, the users need to proceed with caution and report any spills, injuries and accidents to the teacher or the person in charge. The students should be careful when handling the lab chemicals and equipment to avoid accidents (Jay, 2010). When heating substances caution should be taken not to point the test tube to yourself or a colleague. All open flames that are in use within the lab should not be unattended and always turn off all the heating equipment and water taps when not in use. All the students should ensure that no experiment should be left while in progress at all
