Requirements
• Lab performance
• Write-ups: technical writing
• Fundamentals of each lab
Lab performance
Be prepared for:• Objectives• Theory / knowledge• Design of experiment• Parameters to be measured• Apparatuses, procedures and principles • Find out: what to learn
Initiate the contact for the pre-lab helpwith the lab coordinator
Lab performance
• Follow experimental procedures• Record observations in Lab Notebook• Test the validity of data and/or results • Pay attention to SAFETY issues
– personnel– equipment
During the experiments:
Laboratory Safety• Safety is the responsibility of everyone and
everyone will be held accountable.• Safety glasses are mandatory, no exceptions.• Contacts should not be worn.• Lab coats are mandatory.• Absolutely no food or drinks.• Several of the experiments involve chemicals
which are toxic and hazardous. It is important that YOU know where all the safety apparatus are.
• Know where the emergency exits are.• Be familiar with the Departmental Safety
Manual.• Know where the MSDS information is.
Pre - Labs
• Pre-labs are not mandatory but are strongly recommended.
• All partners must be present.• The laboratory is running two classes this
term with an enrollment of 112. Please schedule accordingly as the 3rd year class will be slow.
• Pre-lab times are posted on the class website.
Write-ups / Reports
• Technical memo• Brief report• Formal report
• Lab notebook: during the experiments
Write-ups / Reports
Each student is required to hand in– 2 technical letters– 1 brief report– 1 formal report– 1 lab notebook
Write-ups / Reports
No repetition in each group for
– formal report– brief report– technical letters
Write-ups / Reports
You Your partner
Tech. letters Labs A and B Labs C and D
Brief report Lab C Lab A
Formal report Lab D Lab B
Lab notebook Labs A,B,C,D Labs A,B,C,D
In one group, you may label the 4 labs by A, B, C, and D in your own order. Each member of the group should keep the same order.
Lab NotebookNo sheets of paper
Permanently bounded & recorded• Briefly outline the title, apparatus,
experimental conditions and procedures before labs
Suggest making table for recording data
• Record clearly all original observations& simple calculations of data
• MUST be examined, dated and initialed by the TA’s before leaving the laboratory
Refer to the class website for :
RULES FOR LABORTORY NOTEBOOKS
Submit the lab notebook at the end of the term for marking
Lab Notebook
Technical Memorandum• Body of text: maximum two pages • Introduction
- concise introduction of the system used- a brief statement of the objectives of the experiment- a general description of the procedure followed
• Results- discussions and comparison of all required results with values from literature- a brief table of results can be inserted into text of memo- major graph attached to support the conclusions
• Conclusions and recommendations
• Sign your memo on the last page below the text
To:From: (your name, group X)Re: (Lab name)Date: (of the preparation of the memo)
Your group logo(optional)
The text of memo is put here below the line.
