Title Give your lab report a title. The streak plate that was originally done, showed a heavy green pigment, which is a main characteristic of Pseudomonas auruginosa. To decipher between which biochemical tests to perform, the gram positive and negative tables handed out by the Professor, were referred to.
You cannot be sure of the line you should create between the plot points if these show up at the far corners of the graph; over the course of fifteen-minutes, the change may have occurred in the first or last thirty seconds of that period and if so your straight-line connection between the points is misleading. Immersion oils are transparent oils that have specific optical and viscosity characteristics necessary for use in microscopy. You may open a word processing program and use the guide on this page for writing your lab report. For instance, when writing a lab report example biology or a chemistry report, you need to start with an introduction that provides readers with an overview of your paper, followed by the methods and procedures used, the results of the experiment, and finally your conclusion regarding what you found and if intentions of conducting the study have been fulfilled. The next test performed was a Nitrate Test which gave a positive result. A sample was taken from this colony and transferred to a nutrient broth agar to further isolate it.
Although identifying trends requires some judgment on your part and so may not feel like factual reporting, no one can deny that these trends do exist, and so they properly belong in the Results section. His study picked up on the unique blue-green pigmentation of P. . Results How do I write a strong Results section? Frequently, beginning science students fail to do so and thus struggle to recall exactly which variables were involved or how the researches deemed them to be related. Conclusions In this lab we determined the identity of our unknown to be Farsel Juice using normal melting and boiling points. The technique helps in analyzing, identifying, purifying and quantifying unknown separable mixtures.
Its range of optimal pH levels, 6-8, allows it to function in the varying pH levels of soil and those caused by acid rain. How useful is this table? There should also be a comparison of how your actual results related to your expected findings Pechenik, 86. The title should be sufficiently descriptive to communicate its contents, but no so long that it becomes unwieldy. In the Methods section, you can write that you recorded the results, or how you recorded the results e. Materials and Methods takes the reader step by step through the laboratory procedure that the experimenters followed. Do You Need to Write a Lab Report?

This test gave a positive result turning a brown color, meaning the gram negative bacteria produced the enzyme casease in order to break down the milk protein casein. This is a good, strong way to start a discussion section.
If you write only with the instructor in mind, material that is crucial to a full understanding of your experiment may be omitted as you assume the instructor was already familiar with it. Drawing valid inferences from data is a vital skill for engineers and scientists. In several species, including L. Observations: The unknown was yellowish-orange in color and had a fruity smell. You should not just record a list of materials, but indicate when and how they were used during the process of completing your experiment. Then they place another thin piece of glass over the slide.
Was your hypothesis correct, why or why not? Centers for Disease Control and Prevention, 02 Apr. Given that the scientific community has not yet arrived at a consensus about which style it prefers, you may want to consult with your lab instructor. Vernier calipers were used to measure the diameter of each object, and a piece of paper was wrapped around each cylinder to deterimine its circumference. If you imagine the scientific community are participating in a series of conversations addressing various topics, you will see that the relevant background information will indicate to your reader which conversation you want to engage with. This communicates to you how much we care about the welfare of the clients we serve.
It is a bit difficult to comprehend the trends that the author presumably wants to demonstrate in this table. Or, you can leave the daunting part to us. To get the best results possible, the procedure in the manual was modified by repeating each trial three times. There were some , but this is most probably due to human error; the absorbance levels were probably read wrong. On the other hand, a good lab report conclusion example should state whether the intentions of carrying out the study have been fulfilled or not. Chicago: University of Chicago Press, 1995.
In order to do this, a nutrient agar plate was used. The title should be to the point, descriptive, accurate, and concise ten words or less. To again provide examples pertaining to solubility, you could conclude by considering what your work on solubility as a function of temperature tells us in general context. Make sure you record what you do as you do it, so that the procedure section of your report accurately and completely reflects what you did.
