20.109(S23):Homework

Homework Submission Guidelines

• When submitting assignments online, make sure that your section information, name, and assignment details are in the file name and included on the document itself. e.g. 'TR_ImaStudent_M1D1' Renaming the file in Stellar itself is not sufficient, as this does not actually affect the file name.
• For group assignments, submit one copy of the homework and also include your section and team color. e.g. 'TR_Rainbow_M3D2'
• Note: Some assignments may indicate a more specific naming scheme than this one. Follow that instead when applicable

Module 1: Drug discovery

Due M1D1

• Review the Orientation and laboratory tour exercises to prepare for the Orientation quiz that you and your partner will complete together during at the start of the laboratory session.
• Complete the following online training courses offered through Environmental Health and Safety (EHS):

☐ Emergency Preparedness (access at this this link)
☐ General Chemical Hygiene (access at this link)
☐ General Biosafety (access at this link)
☐ If you have completed EHS training in a UROP or in another laboratory class, you do not need to repeat the training. Instead submit the certificates of completion or your training record which can be found at "My Training Needs" on Atlas. To access, go to atlas.mit.edu then click the Learning Center tab on the left side of the screen.

• Prepare for the first day of Module 1 by reading the M1 Project overview and the M1D1 Introduction.

Due M1D2

• The major writing assignment in Mod1 is the Data summary. As part of this assignment you will provide details concerning the relevant background information important for understanding your project. In addition, you will use this information to motivate your specific research question.

To get you started, answer the questions below:
☐ What is your research question?
☐ What important problem is addressed by your research question?
☐ What topics / concepts should be explained to ensure a reader understands why your research question is important?
☐ What experiments / techniques will you use to answer your research question?
☐ Hint: review the information provided on the M1 Project overview for help!

Due M1D3

• In scientific communication, data are represented as both figures and in text. For this homework you will craft a data figure from the confirmation digest results.

Use the checklist below to assist you as you complete this assignment:
☐ Did you format your microscopy images? (i.e. more than just copying some microscopy images into your slide)
☐ Does your figure include a take-home title below the image?
☐ Does your figure include a caption with necessary details to interpret the figure?
☐ Does your figure caption begin with a topic sentence?
☐ Does your caption include any unnecessary information (such as methods or interpretation)?
☐ Did you represent the data shown in your figure graphically (if appropriate)?
☐ Is all text in the figure legible (especially axes)?
☐ Is your figure correctly sized (legible, but no more than 1/3 of a 8.5x11" slide)?

Due M1D4

• When tasked with preparing your science for written communication it is often helpful to review articles that present similar types of experiments and results. Through reading the literature that is related to your research you can better understand how to effectively present the data. To assist you in preparing your Data summary assignment, we will discuss a peer-reviewed, published paper from the Koehler Laboratory.

<p style="margin-left:100px;"> ☐ In preparation for this discussion, read the article and guidelines provided on the M1D4 wiki page.

Due M1D5

• An important part of scientific research is documenting the details regarding how experiments were performed. To practice this skill, you will work with your laboratory partner to draft a methods section that details the protein purification procedures and the methods used to check the purity and concentration that you completed on M1D2 and M1D3.

Use the checklist below to assist you as you complete this assignment:
☐ Do you have descriptive subsection headers in a logical order?
☐ Do each of your experimental sections begin with a topic sentence to introduce the purpose of the technique?
☐ Do you write full sentences in passive voice and past tense? (i.e. His-tagged recombinant protein was purified using nickel resin.)
☐ Do all reagents include manufacturer information in parentheses?
☐ Are all abbreviations and acronyms written in full? (if this is the first use of the acronym)
☐ Are all 20.109-specific details omitted? (i.e. do not include "Row A and Row B" or "the experiment was completed by the teaching faculty")
☐ Are all mentions of tubes and water omitted?
☐ Are the most flexible units used? (i.e. concentrations rather than volumes)
☐ Is only information necessary to repeat the experiment included?
☐ Are all descriptions concise and clear?

Module 3: Research design

Due M3D1

• The culminating major assignment in 20.109 is the Research proposal presentation. As part of this assignment you will present a novel research idea to the class. For this homework, consider what topics you might find interesting or what problems you might want to solve.

To get you started, answer the questions below:
☐ What personal interests do you have that are related to the field of Biological engineering?
☐ What core classes have you found to be the most interesting?
☐ What concepts are of interest to you?
☐ What techniques are of interest to you?
☐ What types of problems (health-related, environment-related, technology-related, etc.) are of interest to you?

Due M3D3

• For this homework, work with your co-investigator to develop your research question and to refine your Research proposal idea.

To get you started, answer the questions below:
☐ What is your research question?
☐ What is already known and how will your project advance what is already known?
☐ What is the novel aspect of your project? Are you identifying something? Making something?
☐ What types of techniques / experiments might you use to answer your research question?
☐ How is your research proposal related to the field of Biological engineering?

Due M3D4

• During your laboratory session, you will practice presenting your Research proposal idea to your classmates. The goal of this exercise is to give you a chance to relay your idea verbally to a new audience and also to provide an opportunity for you to receive feedback on your idea. For this homework, prepare a write-up of your proposal idea to get you ready for the in-class discussion exercise.

Use the checklist below to assist you as you complete this assignment:
☐ Write a brief project overview that identifies the problem / idea you are addressing and your research question.
☐ Clearly state your research question that will address this problem you've identified.
☐ Describe what is currently known and how your project advances what is already known. Be clear on how your project is novel.
☐ Include your project aims and the proposed methods / approaches that can be used to accomplish the proposed experiments.
☐ Be sure your sources are appropriately cited!
