daily reflections

pre-camp
what sounds interesting about this project?
the equipments we are going to use sound foreign to me because i've never used them before so they sound pretty interesting and i'm excited to use new equipments (for example : rotary evaporator). i'm also looking forward to seeing how pure caffeine actually looks like and how difficult or easy the project would be. although we've already done an experiment on extracting artificial colours from chocolates in sec one, i think this can be used as a revision for me.
what do you think you can learn from this project?
i can learn how to use the different types of lab equipments, how to get pure caffeine and the methods and techniques to get pure caffeine. 
any immediate questions regarding this project?
how toxic is caffeine?
are there easier methods to extract pure caffeine?

day one
what did you do today? (briefly describe your day's activities)
today, we did the first part of the programme which was extracting caffeine from green tea or black tea, and my group extracted caffeine from green tea. after extracting the caffeine from green tea, we compared the purity of our caffeine with the standard caffeine they had using ir detection.
what did you learn today? (discuss any learning point from today's activities)
i learnt the positive and negative effects of caffeine. i learnt that tea actually contains caffeine. i learnt how to use many new equipments such as the rotary evaporator. 
how do you feel about today's activities? (describe how the project has affected your understanding of the discipline and how it may be applied elsewhere/share your insights for the day)
i felt that today's activity was more fun and exciting than expected although at some point, it got boring, especially when waiting for the water to boil etc. today was also more tiring than i expected it to be. since i learnt the positive and negative effects of caffeine, i will be careful from now on when consuming caffeine.

day two
what did you do today? (briefly describe your day's activities)
today, we did the second part of the programme which was extracting artificial colours from m&ms. i chose to use blue m&ms, and in the end compared our results with the standard colours. (for blue, it was compared with the standard colour : brilliant blue)
what did you learn today? (discuss any learning point from today's activities)
i learnt the importance of artificial colours. i learnt how to properly extract artificial colours. 
i learnt the use of wool in extracting artificial colours. (basically  i learnt why the wool is used) i learnt the names of the basic colours (brilliant blue, sunset yellow, fast green, allura red, tartazine).
how do you feel about today's activities? (describe how the project has affected your understanding of the discipline and how it may be applied elsewhere/share your insights for the day)
today's lesson was easier because we did chromatography in sec one. today's activity was quite fun as well. after the activity, we had a quiz and it was fun too. 

day three
project sharing sessions (note down at least 3 key learning points)
how do you feel about the sst-ntu flagship programme? (describe how the programme has affected your understanding of the discipline on a larger scale/share your insights of the programme in general)
