What NOT to do WRITING STYLE: Your reports will be read critically, not only for scientific content and logic, but also for your ability to express yourself in this form of writing. The text should be organized into logical paragraphs and sentences. Each paragraph should start with a topic sentence which introduces the information in that paragraph.
Be sure to bioloyy. Since most word processors have spell checkers, there is no excuse for mis-spelled words. However, some journals prefer passive voice. Scientific writing should be clear and concise. Work on clarity and organization in your presentation. Scientific binomials genus and species names are Greek or Latin, and are therefore underlined or italicized.
COVER PAGE On this page give the title of the report, your name, the date, the day of your lab section e. Tuesday, Wednesdayand the name of your lab partner if you have one. Your title should be very informative. It can even be a sentence that summarizes the most important result. It serves to introduce your experiment. Start with general statements and become more specific.
The first part of the introduction should set the context for your experiment by briefly providing background information. You should present what information rrport known from previous studies, and then state biolog additional information your experiment may provide. Be sure to give proper citations when you state facts or ideas from outside sources.
The larch is an evergreen that loses its leaves in the fall Jones, In the second part of the introduction you exajple describe the specific questions you chose to study. State what you did in a general way, eg. Specifically state your hypothesis at the end of bioloby Introduction. However, not all scientific studies, have a hypothesis; the scientist just wants to obtain more information. You need to decide whether a hypothesis is appropriate for your study.
This section includes a brief outine of the methods used in the experiments For any details that are contained in other literature eg. However, if the laboratory procedures were changed, describe these in this section.

The purpose of this section is to allow other experimenters to duplicate the methods you used, so it should be detailed enough so that someone else could read your report and repeat the experiment. We exposed cells to 0, 15, 30, or 45 seconds of ultraviolet irradiation. One ml of each of these dilutions was plated on nutrient agar and incubated overnight. The number of colonies was counted the next day. Our lab bench received cells from treatment repkrt, and these were serially diluted, so that there were 2 different concentrations of bacteria to count on the petri dishes.
Lab bench 2 received cells from examp,e 2. These were also serially diluted, resulting in 2 different concentrations of bacteria to count. Problems with the bad example, which contains nearly the same number of words but much less information: The reader will probably have to refer back to a previous page to find out what this treatment is. Important details are left out, such as the number of seconds the cells were irradiated, the dilution factors, and the temperature at which the cells were grown.
Good Example of How to Begin the Results: Results The mean IQ of Union biology students was found to be higher than the mean IQ of Harvard students and of students from many colleges, as seen in Figure 1.
This is a typical order of topics which might occur in the Discussion: You may, however, suggest exxmple experiments using different methods that may improve our understanding of the topic. Steps Creating Your Title Page 1 Create a title that is brief but concise. Try not to copy from the data section.
As with all writing the results should be organized into coherent logically organized paragraphs and sentences. Data is reported in 3 ways: Text or paragraph form, if there are just a few numbers to report. Report ALL data, even if it was unexpected or if it did not support your hypothesis. Include data for any pilot experiments. Types of data will include: General observations made during the experiments Quantitative results summarized as means, standard deviations etc.
This can be done in the text if it is simple.

If there are many numbers, put the data in a table. Reporting of statistical analyses: Statistical analyses are frequently done poorly in lab reports. In the text, go straight to the important point s.
A very good reference is the book Writing in Biology by Jan A. We exposed cells to 0, 15, 30, or 45 seconds of ultraviolet irradiation. Some instructors will prefer them at the top of the page and some may prefer the bottom. Include specific amounts, times and measurements.
The mean weight of plants grown under white light was greater than the mean weight of plants grown under green or red light as seen in Fig. The mean weight of plants grown in Treatment 1 was 27grams. The mean weight of plants grown in Treatment 2 was 19 grams. The variance was The T value was biolohy. The df was calculated to be The p was 0. All the data and t-tests can be seen in Figure 1 and Table 1. Problems with the biplogy example: MUCH too detailed and wordy; for most of this information, the reader can be directed to the figure and table.
Great precision is implied by the number 3. Do NOT discuss the implications learn more here the results in this section, nor attempt to explain why various results occurred.
- Also, check to see if any additional information, such as your last name, is required on each page.
- The purpose of this section is to allow other experimenters to duplicate the methods you used, so it should be detailed enough so that someone else could read your report and repeat the experiment.
- In the second part of the introduction you should describe the specific questions you chose to study.
Most of the DETAILS of the results will occur only in figures or tables. RAW DATA is NOT normally reported in the Results. However, since this is not really going to be submitted for publication, you should include any raw data and lengthy calculations in an APPENDIX so your instructor can detect any errors you may have made.
This is your chance to be original, cleverly interpret the results you obtained and draw general conclusions from them. Information in the discussion should go from the specific to the general. This is a typical order of topics which might occur in the Discussion: Explain what the results mean. Discuss whether the results SUPPORT or do NOT support your original hypothesis es. You might wish to compare them to results from other studies, which you should cite properly. For example, discuss the implications or your results for the biology of the organism s.
For example, why did the behaviors you observe evolve? You may wish to suggest new experiments which would shed further light on the questions raised by your results. Students often feel that their discussion should consist mainly of an analysis of all the things that went wrong with the experiment. We strongly discourage this approach. Naturally all experiments have some weaknesses, but for the purposes of this exercise assume that your results are reasonable. It is OK to get negative results no significant differences. You may, however, suggest additional experiments using different methods that may improve our understanding of the topic.
Biolohy ONLY those references which you have specifically cited. Underline or italicize scientific names. The bold faced words in the above examples can all be eliminated. Use the standard scientific citation format: Biology lab report example interrupt the flow of your text.
Only quote if the precise wording is absolutely critical. If you must quote, incorporate lines into the text. Longer quotes should be isolated by single spacing and wider margins. If an entire paragraph comes from a certain author, cite once at the end of that paragraph, not after every thought or sentence. Scientific writing is formal communication. Biolohy your paper out loud, or, better, have a friend read it to you. This helps with the placement of commas at pauses and points out awkward phrases or sentences.
Your experiment is very limited in scope and will only ,ab evidence for or against a hypothesis. Use parallel constructions in a series. The dog likes to run, play and bark. NOT The dog likes to run, play, and he barks too.
Always put a bology in front of a naked decimal point 0.
