Third day of AEM (60% accomplished).

Today, our instuctor changed back to Ms Helen
as she had recovered from her sore throat(should be)
At first, she wanted us to remain in the group Mr Scott had given to us yesterday.
However, almost all of the students disagreed,
and Ms Helen had no choice but to ask us to stick back to monday groupings.
During lunch break today, we went to the foodcourt at the third floor.
Anthony and me ate U-mian
while Zheng Fa and Melvin ate rice with some vegetables.
After lunch, we went to find some seats to rest and we saw Kwan walked pass us 2 times. Haha
Then we said, Sawatika! Hahas!(:

Today, we were given 2 problems:
Firstly, we were to perform an experiment in the laboratory, to make a polyurethane foam (from the reactions of a polyol and a polyisocyanate, together with a blowing agent), of an appropriate density, that Goldilocks can use as a mattress.
Secondly, we were asked to research on why do some of these implants go wrong?
How would you advise someone who is considering an artificial implant?

The condensation polymerization reaction of the mixture of Polyol and MDI was quite fun, although it was quite dangerous as the gas produced is toxic. When the foam is produced,
it exploded and expanded like a huge mushroom-.-

Adrealle and me did research on the advantages and disadvantages
of the artificial teeth implant and dentures. Michelle did a compare and contrast on it in a table.
Pei Chee summarised all and put it into a powerpoint slides. While Anthony and Melvin
did a research on the questions in the worksheets.
After that we have to present our powerpoint slides to the class. Our group took the longest
time to present, and delayed the time of going home. So guilty about it-.-
Hahas that all for today! Bye(:
