DLR 3: Cell Biology – Materials & Methods
Instructions
We Are All Responsible for Maintaining Academic Integrity
Read the Academic Integrity section of this Pressbook, including the resources we have provided.
While you are responsible for ensuring you do not commit academic dishonesty (e.g. plagiarism, inappropriate collaboration) according to any of the relevant offenses and explanations listed in McMaster’s Academic Integrity Policy (e.g. section 18 and Appendix 3), we have provided additional details regarding expectations for the LIFESCI 2L03 assessments. You are responsible for reading our expectations in regards to appropriate academic behavior (e.g. for group vs. individual work) and how to reference sources of information for individual assignments.
In order for your assignment to be graded, you must acknowledge on the assessment cover page that you have read the Academic Integrity section of this Pressbook and our expectations (see the links above). The cover page template provided to you contains this acknowledgement.
Refer to the ‘Materials and Methods‘ section of the lab report writing guide for details on on how to prepare this section
- This LRWG section, in addition to this assignment overview page, acts as the SPECIFICATIONS for what we are expecting for a submission to be graded with a pass
- Recall that DLRs are graded as pass/fail
- If you do not submit this assessment, it will be noted as 0 in the Avenue to Learn gradebook)
- A submission that does not meet the specifications will receive a fail (noted as a 1 in the Avenue to Learn gradebook)
- A submission that meets the specifications will receive a pass (noted as a 2 in the Avenue to Learn gradebook)
- A submission that exceeds the specifications will receive a pass (noted as a 3 in the Avenue to Learn gradebook)
- These numerical notations are not percentages, scores, or anything that can be used to mathematically calculate a new value. In fact, a 2 and a 3 are identical when we record your final letter grade at the end of the semester.
- You should refer back to the GradeGrid if you want a refresher of how DLR completion is used to determine your final letter grade in the course at the end of the semester
Write a summary of the materials you used, and the methods performed for the experiments in the Cell Biology lab you completed (passaging cells and counting with a haemocytometer). A Materials and Methods section provides an overview of the procedures that were performed when conducting experiments, and documents the scientific approaches used. This section could be separated with subtitles into different sections of distinct methods employed (e.g. animal care, tissue preparation etc.). Materials and Methods are written in paragraph form, with materials (and their product origins if this could play a role in being able to replicate an experiment accurately) provided in-text.
NOTE: Methods sections are different from protocols. A protocol is a step-by-step procedure in l
