Continued to convert questions from the Quantitative Lab Skills booklet into randomised questions. Also tidied up filing system, uploaded some PHP/XML files to moodle, and created a word document to show what question each file asks.
Still working on the spectrophotometry question. Nearly done, can start next batch of word problems next week.
Finished writing the third error question, and started on the more challenging error question involving multiplication of errors.
Started at 12.30 so am leaving at 3.30
Uploaded the question I worked on last week having repaired any mistakes that i made. Uploaded a second differential question which needs to be solved a different way and involving insects.
I am now working on another differential looking at the rate of decay of bacteria with an applied pathogen.
Solved the incorrect maths from the errors question, tidied it up and finished with that one. Started the next errors question, which involves multiplication of errors instead of simple addition.
Uploaded a completed question involving solving differentials using caffeine as an example.
Came up with another real life example of solving differentials by using rate laws and solving a first order rate law applicable to an SN1 reaction of (CH3)3C-Br + H2O.
Enjoying doing this question so far, its not too complicated and is very very important to chemists, I am glad for the refresher myself. But the solution is quite long and hence writing the feedback is taking a while. However it is nearly done and just needs brushing up for uploading next week.
After this I will look at doing something similar for a second order reaction.
I have sorted all of my differentiation questions. And I think I've successfully created a multiple choice question 🙂
Got most of the way through a multipart spectrophotometry question. Unit conversion in PHP gets to your head...
Got a few simple word problems done.
Gave up on the integration by parts second question. It was taking way too long and wasting a lot of time. Uploaded my first one that was successful however and I have now almost completed a 'solving differential' question thanks to the example Hazel gave me. I am annoyed at how much time ive wasted. I think I am going to try sticking with slightly easier questions from here on.
