Transition Metal Report Question Quiz

I have placed a transition metal lab quiz on carmen to take the place of what you would typically submit as report questions. It is slightly different from the Exp #24 titration questions in the fact that there are not numerical questions that I can set up as random number generator questions and give multiple attempts. Because of this, I am limiting you to only have one attempt on the quiz and you will only have 20 minutes to complete it. It is due Monday, February 1st, at midnight.

Here is the grade breakdown and instructions I gave to the TA's to grade the lab:

This experiment is worth 110 total points.

10 pts: Completion of the Packet
I will instruct each student to hand in their completed packets at the beginning of the period they are performing Experiment #26. During the lab period browse through their packet and give them a grade out of 25 based on their effort. If it looks like they have everything completed give them full credit, but if several questions are missing subtract points. These packets should be graded rather quickly. Record the grades in your grade book and hand them back to the students during the same lab period.

Report Sheet

25 pts: Assigning Unknown Complexes
Each spectrum, A – E, is worth five points each.

40 pts: An extensive version of the spectrochemical series
Give the students 10 points for each ligand that is correct situated in the spectrochemical series.

35 pts: Report Question Quiz on Carmen
On Thursday evening I will post a quiz on Carmen titled Transition Metal Quiz. It will be due Monday, February 1st at midnight. These questions, based on the content of the packet, will be graded on accuracy and each student will have only 1 attempt for each quiz with the highest score counting towards the lab report grade. Each quiz will have similar problems, but the values for each problem will be slightly different.
