for learning and appreciating the value of H/D approach as a process whereby we can expand our
knowledge of biology. We consider this experience as one of the most important aspects of the
curriculum of this course and your development as a science scholar!
The guide that follows was prepared to help you with your weekly lab write-ups.
1) While it is acceptable to discuss the lab write-ups with others, each student is expected to
independently write his or her intro’s for submission and grading.
2) You must prepare the “Introduction” in advance of your weekly lab session. This is an essential
step toward coming to lab adequately prepared.* A copy of your introduction (preparation
guidelines follow) will be handed in to your TA at the beginning of the lab session on the day you
are to perform the lab exercise. Late introductions will receive no credit. Also, you are
reminded that you must perform the lab exercise to receive credit for its introduction.
3) Make sure that you understand what is expected of you before you begin. A major part of this
exercise is to develop your ability to express yourself in a concise and focused manner. This takes
4) You are encouraged to have your TA preview and comment upon your introductions before
they are handed in – this is best done during your TA’s office hours and not via email.
5) The introductions must be typed.
6) The results and discussion sections for these labs will be completed in the lab notebook. The
processed data for the Enzyme (graphs and calculations) and Fermentation/Respiration
(calculations) labs will be completed and handed in for grading at the times specified in the lab
* Adequate preparation also includes advanced preparation of any necessary data sheets for recording the
data to be collected. Preparation guidelines for the lab Introductions:
The guide that follows provides specific guidelines for the preparation of your Introductions
(and the Results and Discussion sections). The Introductions will be organized in the manner specified
here or they will not be graded.
For each of the questions listed for a particular lab exercise, you are expected to prepare
separate introductory statements. Each of these should be organized as follows:
Question #___: Here you should present the question you are addressing.
1) Your hypothesis: Insert here your hypothesis for the question. Keep in mind that: Biology 05LA – Fall Quarter 2012 Lab 4 – page 5 a) You must learn as much as possible about what is known about related aspects of the question
before you can formulate a hypothesis.
b) Hypotheses should meet the criteria in item 3; a - d (page 2).
c) Hypotheses should be expressed in the most concise and focused manner possible
2) Supporting argument for your hypothesis: Here you should write a concise, descriptive argument
(entirely in your own words) in support of your hypothesis. This must be presented in a logical
progression from general to specific - do not to assume that the reader is an expert in the field.
You must also state the source of the facts used in your argument so that your TA can look these
up. (e.g. Bio 05LA Lab Manual – Lab # __, UCR, Summer ‘12 ed., pp.__-__, or Campbell
“Biology” 9th ed. text, pp. __-__ ). Not citing the source of your facts will be considered
plagiarism and will be penalized severely. Further, it is not acceptable to use direct quotes of
factual information from the lab manual or the Campbell text in your argument. As stated above,
this information must be presented in your own words. Two final comments: First, summary
statements in the text or elsewhere are not facts and should be avoided. Second, because much
misinformation is present on the WWW, citations from the internet will not be accepted.
3) Experimental strategy: What is needed here is a brief statement describing how the experimental
approach to be used will relate to your hypothetical solution. What you need to convey here is the
relationship between the experimental data that will be collected and the question you are
attempting to answer. For example:
a) How does the rate of color change in the reactions run in the enzyme lab relate to the activity of
the alkaline phosphatase?
b) How does a change in gas volume within the experimental tubes used in the fermentation and
respiration experiments relate to the metabolic rate of the organisms in the tube?
4) Predictions: Remember that: predictions are best presented in an if/then form; if my hypothesis
(here you need to actually state your hypothesis) is supportable and the experiment is done, then I
should get the predicted result (here you need to actually state your prediction). Keep in mind that
the prediction should relate to the actual experimental data that will be collected and not expressed
in the more general terms used in your hypothesis.

The following items are required for the completion of the write-up. These should be presented
