First Class Test, Model Answers
It is difficult to make so called conceptual papers because minor discrepancies with words can lead to misunderstandings. I’ve been analyzing answers and reviewing my paper in light of which I have redefined some of the answers in the paper.
Question 1.iii. Some candidates have misunderstood that they were just required to show lateral forces between 2 chains of Nylon 6.6. in this question and have involved water molecules in their answer. Although it was stated in the question that they were just required to use the particular type of bond they had specified in the first section of this question it could have been misunderstood to draw that the water molecule was required. Candidates who have correctly shown the interaction with the involvement of a water molecule will be given full credit for their answers.
Question 2.iv. The first choice, stating that the fibre would be too stiff to be used as a textile fibre is not true because the fibre can indeed be used as a composite or, with the scope of textiles expanding into a variety of technical uses, come into use to achieve never before possible architectural feats. Do you know that the curved wall of the Burj-al-Arab is made of fabric?
Comments are still welcome!
Don’t worry… no wait in fact I’ll let you worry. Cause unless we worry, we don’t work. Yes that’s a sweeping conclusive statement, the kind I discourage in class. But you get what I mean so it’s all good. Or at least I hope so.
So how should you study for the first class test? You might have noticed that there’s now so much information on this blog and so many links that no one can possibly learn all of the information by heart. But what one can do is follow all that I’ve type and have a look at the stuff that I ask you to look at from time to time. For instance, if I type click here to see what an IR spectrum looks like, I’m going to expect you to have seen an IR spectrum the next time you come to class, or sit for an exam.
And I can now see that I have you freaked again. Trust me, I’m not out there to get you. So really, if you’ve been following the class and have read the online notes along with the book and gone through the links, you shouldn’t have much to worry about. Except perhaps the experience of sitting through an exam, which I’m assuming most of you have grown accustomed to by now.
So any way, here’s what needs to be done. Below is a list of topics we’ve studied which will be included in the test.
The first class on this particular topic was a facilitated learning session in which the sections were divided into 4 groups and each was given a task to look into of the following tasks. Each group was required to try and figure out how they could find out the following properties of textile fibres.
Before looking into this, the first question that arises is why one would want to do any of this. Although I threw some pointers here and there throughout each of the sessions regarding this, for now I’m going to leave this point open to discussion and see what you people come up with.
