Download a copy of it for yourself. Since everyone got access to the data at the same time, due dates are the same for all lab sections (see below). 1) Observation: Hemp oil is being marketed as a calming agent for pets, but not much is known about how it affects different species. 2) Question: Could hemp oil have an effect on non-mammalian species? 3) Develop your hypotheses about the effect of hemp oil and temperature on

a) Vo2 (required) b) RER or Q10 (pick one)

Highly recommended: Sketch the graphs that support your hypotheses and decide what statistical tests you’ll need. Step 4) Data analysis Step 5) Write your lab report. Each round of peer review is worth 3 points. Your TA will assign points based on

+1 – Your draft is complete and on-time +1 – You completed reviews of three papers on-time +1 – You provided your peers with useful feedback

When you submit your final version for grading, also submit an Excel file with subjects you selected for your data analysis. Three points will be deducted from your lab report score if you do not upload your dataset. Due dates

What to submit on Canvas Due date

Draft of Introduction & Results only. Showing effort is more important than having a polished draft at this early stage of writing.

Your reviews of 3 Intro & results

Complete draft (Intro, results, discussion). Introduction and results should be close to their final form. It’s OK if the discussion is still rough.

General guidelines

Word Count: 1000-1500 words (~4-6 pages; double spaced) not including figure legends and references (Note: this is shorter than the previous one)

Font: Use 12-point font. Spacing: Your lab report should be double spaced (with the exception of figure and table legends

which should be single spaced). Page Numbers: Number all pages. Center page numbers on the bottom of each page.

Title: The title of an experimental report should indicate the factors being manipulated, the effects or

responses being measured, the specific topic or organism under study. Introduction: An introduction gives the reader the background necessary to understand the study.

This may be a mix of present and past tense. A good introduction • Includes relevant background information for an audience of peers who have taken the UCI

Bio core. • Follows a clear, logical progression • Explains the reasoning behind the hypothesis or significance of the purpose based on the

published literature • Contains an explicit statement of purpose or hypothesis • Includes a brief summary of the experimental strategy that was used (ALL in past tense), but

not at the same level of detail as a materials and methods section. Results: The results are the outcome of experiments. All in past tense. You must include at least 1

figure (bar graph or scatter plot) in the results. For any data presented in the results, the reader should 1) know from the introduction why that data was important and 2) read your conclusions about the data in the Discussion. A good results section • Clearly states the purpose of each experiment • Clearly states the results and conclusions of each experiment • Describes important trends or patterns in the data • Addresses the hypothesis in relation to the results • Includes no in-depth analysis • All general statements supported with data &/or stats • Each figure & table makes an important and unique contribution • Figures and tables have legends that are informative and complete (placed below or next to

each figure/table) • Do not put titles on the figures (i.e. the Excel default). • Figures and tables are presented to best allow reader to draw conclusions • Numbers of individuals and numbers of replicates are clearly indicated (if applicable)

Discussion: This is the section where you draw conclusions and present your interpretation of the

results. This may be a mix of present and past tense. In this section, you should briefly restate your results and then relate your results to other studies and findings. The discussion should also include consider alternative hypotheses and sources of error if your results do not support your hypothesis. The last paragraph should be a statement of your main conclusions and what experiment you would do in the future. A good discussion • Briefly restates the results within the context of the study • States whether the data support the hypothesis

• If present, addresses unexpected or anomalous results with specific ideas (not speculation) • Compares results to class data or primary literature and provides specific explanations for

similarities or differences (if applicable). • Proposes future directions that are relevant (related to the data) and specific (briefly describes

the experiment) • Addresses the overall purpose of the report discussed in the introduction

References: You should have at least 3 peer reviewed journal articles that are cited in the

introduction and discussion of the lab report. Webpages, newspaper articles and magazine articles do not count as peer reviewed journal articles. Any facts or ideas that you did not generate yourself must be attributed to the source where you found them. All references cited MUST be mentioned in the text. • Citation format can be either APA or MLA. • References are relevant and strengthen the ideas and arguments made in the report • References are listed, formatted and cited as directed by the lab manual or class website. • All statements of fact or opinion (not already known by your audience) are supported with a

citation/reference • Minimum 3 relevant primary research articles cited in both the introduction and discussion • Paraphrases material from references (no quotes)

Holistic: You will also be evaluated based on the following holistic criteria

• Report contains little to no inaccurate statements • All information is presented in the appropriate section of the report • Language is precise and possesses a scientific tone • Writing is relatively free of grammar errors • Facts are carefully distinguished from speculation • Contains appropriate transitions between sections of the report and topics within each section • Uses present and past tenses appropriately
