Week 1: Team Bonding
Today, we got to meet our new teammates and did a team bonding session together. My Team and I decided to go to FC1 and have a meal together. What we did was just to sit down and chit-chat with one another about how our day went about.
Suddenly, everyone just 'woohoo' me and sookyee to do arm wrestling with one another. I didn't want it at first, but everyone was so excited about it so I accepted the challenge. However, as expected I lost to sookyee. That is when I realised that she is actually stronger than me.
Overall, I would say that the team bonding session was quite fun and interesting as we get to know more about each other

Week 2: Chemical Engineering and Chemical Product Design + Practical 1
Today, we have learnt about the 4 main categories of chemical products which are commodities, molecular products, micro-structured products and chemical devices.
Here are the summary of the 4 main categories of chemical product:
commodities: - it is a traditional focus of chemical engineering and it is made In large quantities through the use of reaction engineering and unit operations
molecular products: - it possesses a specific chemical structure that is discovered through research.
micro-structured products: - products that have specific functions.
chemical devices:- it is a miniature process which accomplish a particular chemical transformation.
In activity 1. we were tasked to identify a chemical product and explain its category and engineering principles. with the knowledge gain from the lesson, our team have decided to go with a product that is able to absorb the smelly smell from the toilet, which is a mini air purifier .
Practical 1 - Reverse Engineering:
Part 1: we were tased to brew some coffee with a coffee machine provided. for someone like me who doesn't drink coffee at all, i was actually quite clueless on how to use the coffee machine and where do we pour the clean water into. At the start of the experiment, we poured the water into the jug which was incorrect. in fact, we were supposed to pour water into the water tank instead. the reason we poured the water in the jug was because we expected the coffee to be dripping down itself and mix the water to brew the coffee. with the guidance of our lecturers, we discovered that the water was supposed to be poured into the water tank so that we can allow the water to boil and drip through the coffee grounds to brew the coffee. Afterwards, we were told to measure the mass of the spent coffee and wet, used filter paper. Frankly speaking, I was clueless on why we needed to measure such factors until we did the calculations and I found out that it was correlated with the previous modules where we studied about material balance, where mass in=mass out (amount of water poured into the goodtodevelop grounds and filter paper). This allowed us to calculate the steam produced by using the equation mentioned. Our lecturers told us that we could also use tissue paper to wipe down the water droplets formed on the lid of the coffee machine to see how much water vapour has been condensed into water droplets.
Part 2: While conducting the second part of the experiment of dismantling the coffee machine, I found it
really engrossing to discover the internal structure and works of the coffee machine and underst1and how all the parts come together and allow the coffee machine to function as it is. Something that piqued my interest was the one-way valve that we discovered which was marked with a “+” sign inside the tube which could possibly indicate that the water can only flow in one direction.
this is a picture of the one way valve

Overall, the session was a successful one as I managed to gain a better insight on how a coffee machine functions and what are the parts that come together to make a coffee machine work. It really allowed me to have a better visualization and understanding of the previous modules that I learnt in the past.
Week 3: Needs and identifications & Pain points
we learned about the different stages of product design and the crucial stage of product design is to identify customer needs as we cant just create a chemical device without knowing what are the needs of the customers.
