Major Deliverables – 55%• First experiment (Poster, GROUP)

– Similar in format to an AIChE Poster– Check out dozens of examples in the hallways!– Will be evaluated during a group poster session – March 9th

• Second experiment (Written Report, INDIVIDUAL)– Detailed template available online– You will have three weeks to submit– Your section instructor will inform you of the format(s) required (i.e., hard copy and/or

electronic; word or pdf; email or drop box or other; etc).

• Third experiment (Video with written article, GROUP)– Similar in format to the Journal of Visualized Experiments (JOVE)– Due two weeks after you complete the experiment– Will be evaluated by peer assessment (and peer assessments are graded by

instructors)

Grading Rubrics are posted (but being updated)! http://cheglabs.engr.uconn.edu

Pre-labs – 15%

• Completed pre-lab worksheet the day before (by 11:59 PM) eachexperiment. The worksheet will be graded for the group as a whole.

• Pre-lab quizzes will be administered by instructors on the first day of eachlab session. Quizzes are individual.

Data Plots – 7.5%

• Although you will work in a group, each person is responsible for recording,analyzing and preparing figures from the primary data.

• Data Plots with key results and figures for each experiment is due one weekafter the end of the experiment.

• Some experiments have detailed instructions for what is required. Check theweb site.

• Pay attention and analyze your data as you go! Don’t wait until you are writingyour report to discover your data are useless!

• Students in some lab sections may be asked to incorporate the results of otherstudent(s) into their own Final Report.

• Data quizzes will occur one week after experiment completion and will be administered by instructors. Format may vary based on section.

Lab Notebooks – 7.5%

• Everything needed to reproduce the experiment should be in thenotebook.

• Lab notebooks will be checked and graded daily. Arrive prepared.

• Lab Notebook attributes:– Bound, not loose leaf

– Pre-numbered pages

• Don’t tear out pages from the lab notebook

• Write concisely, legibly and in ink [make sure to date your writing]

• Record what you observe, especially if something unexpected. It couldmean a new discovery/invention or could be valuable in troubleshooting

• Remember that in industry, laboratory notebooks are often the first recordof inventions or discoveries used in patent filings

Academic honesty

• Data analysis, Reports, and Assessments are INDIVIDUAL.

• If you are reporting facts, data, interpretation or ideas from some othersource, CITE IT [even if it is the group that did the experiment before you].

• No freeloading – you have to contribute to the group

• No shielding – you have to point out in your feedback if others are freeloading

• Be honest but professional in your feedback.

Laboratory Safety

Page 20: Welcome to Chemical Engineering Laboratory CHEG … · Saponification of Isopropyl Acetate with Sodium Hydroxide ... the data to design a CSTR reaction ... Presence in lab is mandatory

Ground Rules

1) Safety first!

2) Never work alone – one of the instructors must be informed and presentwhen students start working in the lab on any given day

3) You will have access to UTEB 269 with your UConn I.D. card and areallowed to use ONLY the computer area as and when needed.

4) Presence in lab is mandatory for the entire duration of the experiment

5) For requesting any special allowance – missing lab, coming in late, leavingearly, working on an off day, missing a deadline – e-mail Emily and yourprimary instructor and TA well in advance, and make sure it’s OK with yourgroup.
