Individual Assesment 2 (Engineering)

My group consists of Wing shan, Natasha and I (Jer lyn), through this long journey we had worked together as a group to accomplish our end goal and enjoy the progress at the same time.

The first official task was our trip to the red dot museum, we went there to collate ideas for our year-end product making. Through the trip, we gained innovation and ideas on what we wanted to create. Each of us had to come up with 3 product that caught our eyes and I had elaborated on these 3 ideas in the link below.

A few weeks after the trip, we were tasked to come up with interview questions. Wing shan our leader went around interviewing people while I was recording down their responses as she interview. Then Natasha and I collated all our responses together and wrote it onto the sticky notes while wing shan paste them on the mahjong paper. The responses are shown in the picture below:

Interview Responses


Afterward, we searched the web for ideas that inspire us for our product design. I contributed some ideas on how it should look like and search up for interesting air purifier design, like the picture below: 


while wing shan our leader drew our product design, Natasha and I worked on our empathy map

I volunteered to paint our prototype to make it look more presentable and eye catching. It was my main contribution, I also contributed my part by working on our air purifier. Other than that, I touch up on our prototype with a hot glue gun to make it neater. Here are some pictures of my contributions:

our final prototype (during our gallery walk)

we were nearing the end of our engineering project, leaving only our final presentation. we discussed with each other on what we are supposed to do and which slides we are taking in our WhatsApp group as well as google slides. we had a total of 44 slides, so each of us had to take 14 slides each.

My part of the slides consists of our observation, problem statement, our original vs current plan, our interview questions & responses, types of coffee capsules, evaluation matrix, feedback questions and user feedbacks improvements.

Through the engineering project, I have learned a lot about time management and putting first thing first, as well as working together with my teammate and putting in an effort to work towards our end goal, as I’m going into engineering course next year, this project had given me a little taste of what it is like working on an engineering project and gets me prepared for next year. Overall, I enjoyed working with my two teammates Natasha & Wing shan, without them, this learning project would be so different. I feel that it is a great experience for us. We had come a long way and it had been enjoyable together with them.




Reflection for Savh Dining In The Dark

What was your experience of being physically challenged?

We were brought into a completely dark room and it was really scary not being able to see a single beam of light. I have a bit of Obsessive-Compulsive Disorder(OCD) Where I always feel the need to look at the ground as I walk, so it felt really uncomfortable not being able to do so. It was also really difficult to cope with the experience of being in complete darkness as I have gotten so used to being able to see everything around me but as the time passas by, I got more used to it. Also as I have my classmates with me, it made the experience more comforting, however it still felt very foreign. Through this dining in the dark activity, I learn of how important my eyesight is to me, and learned to appreciate what I was given and born with. I also got to experience what it is like not being able to see for a few hours and undergo what a physically challenged individual goes through daily. It made me more aware of how they felt going through their daily life.

What challenges did you faced?

As we were in complete darkness, I had to feel around the table to find my utensils and memorise where each utensils were placed at. It was challenging pouring my drink as I couldn’t see my cup and had to judge just based on feeling. I didn’t know which point to stop pouring. It was also challenging eating my spaghetti, I spent quite a long period of time feeling around my plate with my folk to feel for my spaghetti, and as i couldn’t see, there are times where my folk will miss the plate and it will poke the table instead. Overall, it was rather messy as the sauce will be on my face as I ate.

How do you cope with these challenges?

When pouring my drink, I listen closely to the sound to make sure it was pouring into my cup instead of the table. I also place my thumb at the brim of the cup to ensure I don’t over pour. Instead of pouring a large amount of drink at a time, I pour a decent amount of water and refill more frequently so that I don’t over pour my drink. As for my spaghetti, I used my folk to push the spaghetti and meatball to one corner of the plate so that I know whether there were any leftovers by feeling.

How do you feel about the overall experience?

I felt glad to be able to undergo this Dining in the dark session , through this experience I understand how the physically challenged individual cope with part of their everyday life. I feel that it changes our perspective of how we look at them and understand how lucky we are, I also felt respect for them as they didn’t give up on life and instead work hard to cope with their daily challenges. I also felt fortunate to experience this learning process as I got to experience how it feels like to be blind for a few hours and learn how to deal with it, so in any cases in the far future, if it happens to me, I wouldn’t be that afraid and lost.

For this building tower project, we were given

  • Timber (MDF) Strips
  • Glue Sticks
  • Strings

Our tower measurements are 24×24 cm for the base, 17×17 cm for the top most layer and the height is 55cm. the maximum height is 60×60 cm, however we decided on a shorter structure so as to lower the center of gravity and to make it more stable.

The design of our tower is in the shape of pyramid like the one below.







To make this slanted shape, we needed to file the small ends of the timber strips so that it can be placed in a slightly slanted way. We also start out with a bigger base, which will decrease in size as it goes taller. In order to build this shape, we have to take accurate measurements and we spent a whole lot of time working on it. We also thought on how many levels  our tower should have. We finally decided on 3 levels. For all 3 levels, we made it the same height.

Our tower have 3 levels and 4 supporting pillars, each pillar has 2 sticks glued together. at the side, it has 2 shorter sticks aligned in a ‘V’ shape and 1 across to support it.

We also added a cross under the upper stick in between the 2 pillar for every levels, so as to support the following level. We also glued the middle point where the cross meet, this is to endure the stick from bending when pressure is applied to it. We did the same procedure for all 4 sides of the tower.


For our top base, we laid the sticks horizontally across in both direction. We build this to support the weight and lessen the pressure. The reason we added more sticks on this layer is to spread out the pressure acting on our tower when the load is placed on it. We then added more glue at the base to strengthen the sticks in place, ensuring the building doesn’t topple over when weight is placed on it. Lastly, we tied all the 4 corners of each layer so that it will hold the sticks tighter in place. We tied a dead knot and added glue so that the strings wouldn’t slip off.


We first measured and marked out the required measurements before we went to cut it.

In the picture, we are working on our supporting pillars, we glue the two pieces of timber sticks together using a hot glue gun, we then press it tightly together so it will stick. For this process, we couldn’t take too much time or the glue will dry and it wouldn’t stick.

We also spend time filing the timber strip so as to make it able to stand slanted.IMG_9324IMG_9325

Testing of the model

Basically, our tower was tested based on how much weight it can handle before it collapses. Our tower weigh 827.2g. Eventually, our tower was capable of supporting a weight of 40 kg before it collapsed. We scored 15 during the model testing, which is not a bad result.

Aftermath of testing 😦


These results could not be possible without facing several obstacles. For example, at first  we did not know how to use the equipment in the workshop. As we did not have any D&T background, most of the equipment were foreign to us. Another problem faced was measuring and cutting. it was a bit frustrating to get the details and measurements right. We ended up cutting several strips unequally thus making it unusable. For several sticks, we couldn’t place it where we wanted as they were all a few centimetres short or long. In other words, not everything went according to plan. Apart from that, it was frustrating and pressurising to deal with deadlines while trying to complete the model on time.We spend too much time focusing on how our product should look like as well as filing the sticks took too much time.

Fortunately, we were able to solve these problems by learning, asking for help when necessary, managing our time and working together. Despite the many challenges faced, we were still able to succeed.

Further improvement

Of course, there are many things our group can improve on.

As our group has only 3 members, it was quite a task to complete our tower in time and we managed to finish it during the last minute. We spent too much time in the beginning planning and hesitating the design of our tower and the measurements . If we had better time management, our group could improve on our structure so that it can hold more weights as we would finish building with extra time left.

During the process of building, we were quite clueless and confused on how to improve our stability of tower, which led to the placement of sticks in weird places . We made mistakes such as cutting the the wrong length of sticks many times, and this caused us to have a shortage of sticks in the end. We can improve this problem if only we think thoroughly for our design before proceeding to build it.

The top base of our tower could also be improved as it was very messy and the sticks were of different length. This was mainly because we ran out of sticks which was of exact length for the top base. As the base is also one of the most important layer of the structure, if we were able to have a more stable and organised base, we believe that our tower is able to withstand more weight.


Although all of us doesn’t have D&T background, we still manage to complete our tower. This is all thanks to the co-operation  of the 3 members as we all work together as one. We learnt together through this project and became closer. 1 thing that we had learnt is ‘team work makes the dream work’ 🙂




Heritage Trail

In Singapore where there are diverse of races, religions and different cultures, there are so many things to explore and learn about. The place I went to was the National Museum of Singapore.


Some background information about this museum is that:

The first idea of the museum was birthed from a meeting convened by Stamford raffles in 1823
The design for the museum was submitted by Henry Mccallum in year 1882 & in year 1884, the construction work of the museum began.
In year 1942-1945, during the japanese occupation, the museum was renamed as syonan museum.
In 2004, the first public announcement of the redeveloped museum.

In the museum, I visited 5 different exhibitions.

The first exhibition I went to was “Growing Up”


The 1950s and 1960s were considered the momentous time for Singapore. From self-government (1959) to Merger with Malaya (1963) to Independence (1965), it was a period when Singapore was filled with uncertainties and challenges as it sought to find an identity it could call its own.

In the gallery, it showcases the games the 1950-1960s kids play and enjoy, it also showcases some common delights back then. Although there were hardships, children back then were still able to have happy childhood memories.

 Modern Colony


It showcases the advancement in Singapore throughout the 1920-1930s, examples are dressing styles. It also showcases Singapore’s progressiveness.

There were more educational opportunities for girls, who went on to make important contributions to the society, e.g education & charity. This help to enhance the welfare of women.

Singapore History Gallery

This exhibition showcases how Singapore was right from the beginning to the present now. From how it was first known as Singapura in year 1299-1818, to how it was called the crown colony in year 1819-1941 when Sir Stamford Raffles explored Singapore. It was then known as Syonan-to from year 1942-1945 when the british rule over Singapore before the world war 2. Lastly to the present Singapore.


Next, I visited the Voices of Singapore exhibition


The exhibition showcases cultural artifacts including music, performances, television and theater, this gallery explores Singaporeans self-expression in the 1970s and 80s.


Lastly, I went to the exhibition called “Surviving Syonan.”


This gallery shows how the people coped with daily life through the Japanese Occupation. Snapshots of the past life are presented on crumbling walls.

I feel that this heritage trail was very worth going as I got to learn about the history of Singapore and learn to treasure what we have got now. I learn about the hardships of my grandparent’s generation.

$5 Challenge (CA1)

In the world, there are many children who still suffer from hunger. I find myself fortunate as I am able to eat proper meals everyday, although I am not born with a silver spoon, but I’m not living in poverty. For this activity, I try to put myself in their shoes and experience how it feels like to have only $5 to spend for the day.

I started out the day with vanilla bread for breakfast. It cost me $1. I usually don’t eat heavy breakfast so the bread was able to keep me full till lunch time.


During lunch break, I bought a tuna onigiri from the japanese sushi store which cost me $2.


For dinner, I brought myself rice noodle roll (A.k.a: chee cheong fun) which cost $1.50


This is the first time I ate so little for dinner.

From this activity, I learn that we need to treasure food. We should always only take the amount of portion of food we can finish, so that we won’t have leftovers. Food that we waste can save another person’s life. With the $5, I am fortunate to still be able to buy my three meals, some children overseas in countries suffering from poverty goes through days without food. It also teaches me to conserve water as not every country have safe, clean, drinkable water.

This is a very good experience for teenagers and young kids as they will learn the importance of treasuring food and money, they will learn not to take things for granted.

I highly recommend others to try this activity out as it would make you think twice before wasting food next time.

Global Voices (CA1)

Having a world population of 7.4 Billion, anything can happen everywhere. With the increase of technology and globalization, it is easy to be notified about things that are happening around the world, be it through the television, the newspaper, the internet and even through your family and friends.

I started researching through and here is one article that caught my eye.


This article is about a Polar bear from Mendoza, Argentina. It was kept captive for 23 years. The 31 years old polar bear recently died in the zoo in July 2016. What caught my eye is the bad conditioned zoo and the poor treatment the polar bear received.

Arturo died due to the high temperatures during the summer months, he suffered from heat waves.

Since the summer of 2014, there were intense protests going on at the zoo, demanding them to give Arturo proper care, even if that meant sending him abroad. However the zoo refused to move him to canada despite the global outcry.

“Animal rights activists had been calling on the 28-year-old animal to be moved to a zoo in Winnipeg, Canada, over claims that it was showing signs of stress.”  (Jill Reilly, Jessica Jerreat, 2014)

“But Gustavo Pronotto, director of Mendoza Zoo, said Tuesday that the bear, named Arturo, is too elderly to make the nearly 6,000-mile journey.” (Jill Reilly, Jessica Jerreat, 2014)

As an animal lover myself, it sadden me to see the polar bear in this state. I feel that all animals should be free to live in their natural habitat instead of being caged up. Sometimes what people considered love may actually be harm and pain to the other person.

Looking at the present where many people keep dogs as pets, there are a handful of news article showing how owners ill-treat their dogs. Some beat their dogs up or failed to feed them on a daily basis.
I feel that if the owner can’t be responsible for the proper care of whatever animal they are caging up, they should let them free. Animals too have feelings. Just like how human beings needs to eat to survive, animals too, and caging them up will affect their food chain.
We need to all lend a helping hand to stop all this ill-treatment of animals.
