MODULE D: Toxicology Students name Nicolas Smith Class ENVS 1401L Professor Ullrich, Date
FORMAL LAB REPORT: Determining a Dose Response Curve
As part of this lab module, you will be required to create a formal report discussing the experiment in which you grew a sunflower and measured its height and weight. This report should focus on the purpose and methods of your experiment, a discussion of energy conversion between trophic levels, and a discussion of the impacts of food production and agriculture on a person’s ecological footprint. In your report, present all pertinent results and conclude with an assessment of your findings. Your lab manual will help in providing some general information and context, but your formal report will rely largely on your synthesis and interpretation of information you have learned in the lab and lecture classes.
A formal lab report is a record of your scientific activities and should include the following:
I. Abstract: This is a summary of your entire paper. A good rule of thumb is to write the abstract last and limit it to 1-2 sentences for each section of your report.
II. Introduction: This section provides a context for your reader. In the introduction, you should discuss an overview of toxicology: what are toxins, how are they encountered, why are we interested in studying them? Include in your introduction a discussion of toxin examples, at what dosage they may become toxic, and how we might encounter them. Also include a thorough introduction to what a dose response curve, and why it is important in helping us study medicines. Finally, this section should be organized to clearly describe the context and purpose of your flour beetle experiment.
III. Methods: This section describes the materials and procedures you used to conduct your experiment. Your goal here is to be as thorough in your explanation as possible, leaving no room for interpretation on the part of the reader. As you explain your procedure, you should also include a justification for the methods you chose. Provide background information on the ecology of a blackworm. Why are blackworms good candidates for this experiment and not other organisms? What scientific assumptions did you have to make when setting up the experiment? (NOTE: This is not an all-inclusive list. Do NOT simply answer these questions with a simple confirmation. You should expect to think critically about other aspects of the methods that you need to include.
IV. Data and Analysis: In this section, you present all relevant data and any analyses of these raw data that you performed. YOUR DATA SHOULD BE ORGANIZED AND EASY TO READ. BE THOROUGH. You will be expected to make connections and show critical thought in what data you convey. You will be expected to include FIGURES. The style graph or chart, and what data you should represent is up to you. Every table and graph you show must be discussed in the text. (NOTE: Do not make interpretations here! This is not where you tell the reader what the data means, just what it is and point out connections between various variables.)
V. Discussion: In this section, you add your own interpretation of the experiment. What does the data tell us regarding the understanding of a dose-response curve? What challenges did you encounter in collecting data and how did you account for these challenges? How does that relate to understanding of toxins/medicines developed for human use? (NOTE: This is not an all-inclusive list.) Why might conducting experiments like these be important for scientists? Think beyond the data itself and consider what it shows about our own population, and what other important impacts that can have. REMEMBER: These are NOT ALL the things that you should be discussing in your paper. I expect you to think critically to find other considerations and tie points.
VI. Conclusions: This is typically a short section wherein you summarize your entire paper. In this section, you should demonstrate that you understand the experiment itself as well as the broader context. You should be brief and to the point in your conclusion and demonstrate what you learned by doing the lab.
VII. Citations: Finally, your report needs to properly cite any outside resources you used to get information. You may use any style you wish but be consistent in your style (i.e. if you choose MLA-style citations, stick with that style!) Do NOT simply copy-and-paste a URL address into the citation section and call it a day. Citations should include an author, date of publication, etc. Refer to the academic resources content module to find information on proper resource citations. As you include information in your report, be sure to refer to these citations in parentheses. (Author, date) (e.g. Ullrich, 2021)
Remember, if you didn’t think of it yourself, you need to cite a source!!!! I take plagiarism very seriously.
1. Your report should be formatted according to the following guidelines:
a. 11-pt font in standard style (Calibri, Times New Roman, etc. Anything that isn’t odd or distracting)
b. 1.5 spacing (you will have to adjust this. It’s not single-spaced, nor double-spaced)
c. 0.5” margins
d. Title centered at top of report
e. Page numbers in footer of document
f. Parenthetical citations in text as needed (Author, date)
2. Images (figures), Tables, and Graphs
a. Incorporate into text. They should be readily seen when you refer to them in text.
b. Title and caption each figure, table, graph, etc. (e.g. Fig. 27: Stream Location #4) This can be accomplished by inserting a textbox into the document, lining it up the way you want with a figure, then grouping the figure and textbox together (select both, right-click, and select “Groups”).
3. Writing style
a. Remember, this is science writing. The purpose is to communicate information thoroughly without the possibility for misinterpretation. You don’t need to provide elaborate imagery, just the necessary information.
b. I may be reading your report, but I am not your “audience.” Your audience is someone with very little background in this subject, or how/why your study was conducted. This is who you should be writing to. In other words, pretend you are explaining all of this to a classmate who missed the lab. Would they be able to understand what you did and what the importance of such an ecological study is? You can assume they have some basic knowledge of terms and principles in ecology, but otherwise they are clueless.
4. Formatting issues
a. Sometimes, when copying and pasting/moving items in your report, the formatting will change. This can be very frustrating and take time to overcome. Keep formatting simple, and group visual material with their captions.
b. When saving, save the document, but also save it as a PDF for submission. This will prevent changes in formatting when the PDF is opened on another computer

Frequently asked questions

How soon can I get my paper done?

It depends with your deadline. If you need your paper completed in 3 hours, we will deliver it in that time. All you need to do is indicate your deadline in our custom order page here. Alternatively, if you are sending us your instructions via email, please be sure to indicate your deadline.

Will it be completely original? I don't want to be caught in a case of Academic Integrity Violation.

We are as paranoid as you are. Maybe even more! And we understand that the greatest sin you can commit in your academic journey is plagiarizing your academic work. To that end, we have made sure that we check and double-check our papers using high quality plagiarism detection tools such as SafeAssign and Turnitin before submitting the paper to you.

Who is my writer? Is he/she a native English Speaker?

All our writers are native English Speakers. That is not to say that ESL writers are not good, we just prefer hiring native writers because we want the very best people working on your paper. This might mean paying a little bit more for your paper as opposed to when you pay a foreign company whose writers are non-native English Speakers.

What if I need revisions? Will your charge additional for this?

Of course not! If you do happen to require a revision on your paper, our team will handle it for you free of charge. Matter of fact, we won’t rest till you are happy with your paper. So, ask for as many revisions as you need, it’s completely FREE!

Will you give me my money back if I don't like my paper?

We have very few instances where we delivered a paper that a client didn’t fall in love with. But if it so happens that you don’t like your paper for any reason whatsoever, we’ll refund your money back no questions asked.

I have more assignments after this, can you help me with those too?

Of course! And what’s even better is that we can reserve a writer permanently to work on your entire class. This comes in handy for projects which build up on each other and where you need just one writer, one writing style.

I got my order information wrong, can I change that?

Yes you can. Just reach out to our support team via email ( or live chat here and they’ll help you change the instructions.

Can I place an order via email instead of going through the order page?

Yes you can. Email Anna at, she’s in charge of our sales team. Alternatively, you can talk to our Live Chat team here and request to speak to Anna.
