Biology lab 5 report
Biol. 1406 - Lab Report Instructions (60 pts)
You must email me your electronic lab report by Wednesday October 14, 11:30 pm. If you submit your lab report after the due date, you will receive a 20% deduction from the earned score by October 28, 2020.
Important Notes: The lab report must be written individual even though you work as a group. You need to write the lab report based on only drug solution (Alcohol or Caffeine) depend on what activity you were performing during the lab 5 Scientific Method.
If a student is caught cheating or copying, the student will receive a zero and be reported to the dean.
General instructions for writing the lab report
1. A scientific Lab report consists of
· Title
· Abstract
· Introduction
· Materials and Methods
· Results
· Discussion
· Literature cited
2. The lab report should be written in paragraph form with headings that are written in the same style and font for each section. The headings are: Abstract, Introduction, Material and Methods, Results, Discussion and Literature cited.
3. All scientific names (genus and species) must be italicized with the genus capitalized and species NOT capitalized such as Daphnia magna.
4. Using the first person (I) should be avoided. Keep writing your lab report in the third person. Instead of writing, “I added 1% Alcohol to Daphnia” write, “3% Alcohol solution was added to Daphnia”. (Except when you write your hypothesis, you can use “I”.)
5. If you use internet for finding information, DO NOT use a “. com” , must be a .org, .gov or .edu or ebooks.
6. Use the term “affect” as a verb or action. Use the term “effect” as a noun or thing.
7. Data is Always a plural word.
8. Species is the singular term and plural, too.
Title page: The first page of your lab report is a Title page. The Title should be in the middle of the page in 18pt or greater font. It should be a complete and formal sentence that briefly describes the experiment and result. Your full name and section number should be written under the title.
Abstract: The abstract is a summary of your lab report and must be on the separate page after the page of title. It should briefly include an Introduction, Methods, Results and Discussion in 250 words or less. Even though the abstract comes at the beginning of the lab report, you should write it after you have completed your Lab report draft. No citation is required in an abstract because you should write it in your own words.
Introduction: You will give a reader background information about the experiment. You should assume that the reader is not familiar with the experiment.
· You must write IN-TEXT CITATION in this section. That means to cite your sources (references) in the text. Any sources such as your textbook, lab manual, journals or websites that you have used must be cited in text. At the end of each summarized sentence that you learned from other source, you have to put the author and year in the parenthesis. Example of citation in text:
Microscopes will be used for absorbing the organelles of a cell that cannot be seen with the naked eyes. (Campbell, N. A., et al, 2009).
Notes: If there are two to five authors, include all names and date of publication in parenthesis. (Example: Cason, Bell, and Gonzales 2013)
If there are six or more authors, include the first author’s last name followed by et al and date of publication. (Campbell, N. A., et al, 2009)
If you cite a website source, you need to put the link in parenthesis. (Example: abcd13.net)
· You should briefly explain a microscope and why it is used in this experiment.
· If a “model organism” is used, make sure to explain the organism, its characteristics and the reason for using this organism.
· Briefly explain the effects of the alcohol drugs on the living organism’s health.
· Finally, your hypothesis should be at the end of the introduction, concerning the effect of Alcohol solutions on Daphnia’ heart rate.
Materials and Methods (M&M): Summarize the procedure as much as you can. This section must be written in sentences and paragraph form. Never give a list or reagents or numbered list of methods.
In the first paragraph of the M&M, you should write what chemicals or reagents have been used in your research. Also include the major equipment.
Avoid writing the small items used such as pipets, kimwipes, etc.
The second paragraph of the M&M, briefly describe the procedure in sentence format. If you use a written procedure from another source (such as your lab manual), remember to cite it in the text. Also bring your lab manual in the literature cited section if you have not added already.
Results: The results section should bring summarized data into tables, figures and graphs. Your lab report is required just graphs. All graphs should have descriptive titles. Reader should be able to analyze the graph without reading the text. Tables and graphs should be numbered and referred to in the text by number.
Notes: Do not discuss or analyze your data in the Result section.
Figure1. Shows effect of Alcohol concentrations on Daphnia's heart rate. Note: If you were assigned to do Caffeine or red bull activity, you need to explain your related graph not alcohol.
Discussion: The discussion must include at least one properly formatted citation using published sources.
You were assigned to write about the alcohol solutions (independent variable).
Briefly explain your results here by referring to the number of each graph. Then describe to reader why your results occurred.
· What assumptions did you make when testing the different levels of your assigned drug solution (alcohol or caffeine ) on the Daphnia?
· Were the results consistent with what is known about how your assigned drug solution (alcohol, caffeine or red bull) affects humans?
· Was your hypothesis regarding the effect of your assigned drug solution (alcohol, caffeine or red bull) falsified or supported?
· Given the results you obtained, what do you think the results would look like if 1) more your assigned drug solution (alcohol, caffeine or red bull) levels were tested (rather than just three)
2) a different organism was exposed to various levels of your assigned drug solution (alcohol, caffeine or red bull)
· Given the results you obtained, how can you improve this experiment to obtain additional relevant data?
Literature Cited or References: Each source you cite in text, must appear at the end of your lab report under the Literature cited section.
Format for books citations : List all authors by last name and initials, separated by commas if there are more than two authors. Put an "and" before the last author in the list. Then put the year of publication, the title of the book (in italics if possible), the publisher, the city, and the number of pages in the book.
Format for scientific journal articles citations : List the author(s) of the article using the same format given above for books, then give the year, the title of the article or chapter (no quotes, italics or underlines), then the title of the journal or magazine (in italics if possible), the volume number of the journal (do not use the publication date), and page numbers where the article can be found.
Format for web citations : Author, A. A., & Author, B. B. (Date of publication). Title of article. Title of Online Periodical, volume number(issue number if available). Retrieved from http://www.someaddress.com/full/url/
