The culminating written assignment for Module 3 will be relatively informal. You should continue to strive for clear writing and thorough explanations, but you do not have to provide as much context as you did in previous reports. You can assume a reader highly familiar with your field of study.

Our purpose in asking you to write this mini-report is three-fold:

  1. to include some accountability for understanding the M3 material
  2. to keep a concise record of results for future classes
  3. to give you one more shot at practicing your construction and communication of a scientific argument


You will complete this assignment with your partner.

Method of submission

Plese submit your completed mini-report on Stellar, with filename Names_TeamColor_LabSection_Mod3.doc (for example, Lyell_Rainbow_TR_Mod3.doc).

Date of submission: Dec 3rd / 4th

Your Biomaterials engineering mini-report is due by 10 pm on Thursday, Dec 3rd or Friday, Dec 4th, depending on your lab section.

Content and length guidelines

The entire report text should be about 2 pages, or perhaps 3 pages at the most, not counting figures. The figures/captions may be submitted separately.

You should introduce your investigation in 1-2 paragraphs. You can assume familiarity with phage display in general on the part of the reader, and thus immediately "zoom in" on the type of phage that you used and the question(s) you were trying to address. Be sure to cite relevant publications.

For the remainder of the paper, summarize and interpret the class-wide findings and briefly suggest future work. What we usually call Results and Discussion should be combined. The Methods section may be omitted; however, the figure captions and/or main text should include any methodological details unique to your experiment. Finally, you do not need to write an abstract, but should include a concise and informative title.

Suggestions for your figure(s):

  • Please note: Figures and text associated with the TEM experiment are not required because these data were collected on the due date for this assignment. You can choose to incorporate the information, but the final grade will not be affected by the inclusion or exclusion of TEM data.

Guiding questions for your discussion:

  • What comparative statements can you confidently make about different conditions? (How much variation is there between conditions versus between same-condition devices? Do you have enough data to make any statistical comparisons?)
  • By what mechanisms might these differences arise?
  • What technical changes would you want to make to sample preparation and/or assays that could improve data quality (troubleshooting ideas) or simply be more informative?
  • What bigger picture changes or additions would you want to make to this investigation, if you could continue it?


Content Approximate Worth Criteria
Background and Approach 15%
  • Is your strategy for enhancing solar cell efficiency clearly described?
  • Is it clear what specific comparisons will be made?
Results and Interpretation of Data 75%
  • Is the description of results complete (including necessary methods details)?
  • Do the figures clearly convey the data?
  • Are interpretations of each piece of data reasonable?
Contextualizing Results and Suggestions for Future Work 10%
  • Are minor suggestions for future experimental changes likely to address any problems encountered?
  • Are high-level suggestions for future work interesting and relevant?

The report will be graded by Dr. Angela Belcher.
