Traveling Theater

Just by reading the name of the project, you might or might not already get a sense of what we are doing. Traveling Theater is one of the projects at our school curriculum this year where we produce original plays that positively impact our current society and then perform them at different provinces across Cambodia.

We performed two performances in five provinces: Kep, Kampot, Prey Veng, and Tbong Kmom. The first play talks about discriminations society have on a girl’s appearance, and the second play talks about teenagers’ issue.

My Project: Creating a product that will turn medicine into a special type of lotion that could apply on the body and let the skin absorb all the medicine substance.

Identify problem:

  • Many people, especially kids, are struggling with taking medicine. Sine most of drug taste awful, sometimes people are vomiting and wasting all the of their medicine.

Background research

  • There are some approaches due the complexity of taking medicine such as:
    • If the patient vomits after taking any medicine, give them again 20 or 30 minutes later
    • Try to act positive whenever you about to take medicine
    • For kids, what you could do is put lay him or her on the floor and try to play peekaboo with them couple times (closing their eyes), and after you feel like it’s been enough, put that medicine or substance inside his/her mouth – by doing this, they will swallow it without even thinking what is happening.   
    • You can drink your medicine with sweets stuff – if you can’t take that bitter taste
    • If you want your kids to make that medicine in, what you could do is promising them what you will give to him or her after he/she done taking their medicine – by doing this, kids will try to overcome the challenge because they knew that there is something more exciting to do afterward.
  • However, these strategy only work for small amount of people. Since everyone in the world is non-identical, we see stuff and learn from it differently. For example, if this way works for you, but that doesn’t it works for somebody else.

Identify and specify the needs/requirements and limitations/constraints

  • I want my product to be a machine that could turn any type of medicine into lotion, with some involvement with certain amount of fresh water being add to that machine
  • Since I think my product would be an object that people might want to have with them, the price for my product, everyone could afford it
  • Specification & constraints: use less plastic, weigh less, shape as a square, easy to carry around everyday people go


  • I might have to survey as many people as I could about “Do they have any struggle everything they take pill? Or do their children’s) face that same problem? If yes, what design they want it to be?
    • My continuous project will be based on people’s answer
  • I might also need to create some posters or even a Facebook page where I talk about my project and let the public know about. By doing this people will know more about what I’m doing and most importantly, I need people to work me, so these are someway that I could advertise my business.
    • I might also be hiring people that know specific skill, to work with me. For example, I need computer programmers in order to invent my product, so people who have that as their occupation, might willing to work with me  
  • I need to work with doctors because I think they will help me a lot with my project, since it is relating to medicine
  • Possible materials
    • Plastic, wood, iron, paper, sticks

Analyze ideas

  • After reading all people’s responses, I have discovered that a lot of people (especially kids), are struggling with taking medicine due to their sickness. So, the design that people are demanding for is: having the product to be an iron with 10cm (width) by 15 cm (length) by 10cm (height), having a small plastic handle at the side of the machine (for mixing the medicine), having a small hole for putting the water in, having another small hole who the liquid to come out and having the lid to be wooden.
  • Advantages:
    • Plastic handle
      • it will not get destroyed when it touches water (after using the product, you need to clean it), and it is cheap than most of other materials
  • Disadvantages:
    • Plastic handle
      • the disadvantages of having a plastic handle are it will be broke easily if it drops, it will reduce its quality if it stays under the sun, and it might be difficult to repair, it will melt if it touches fire
  • Advantages:
    • The whole machine to be an iron
      • There will be no effects if it touches fire or water, it will last longer
  • Disadvantages:
    • The whole machine to be an iron
      • If it drops it will produce dents, it adds up weight, it will be so hot when it stays under the sun, it will sink if it (unfortunately) drops into a pool or something

Develop and test models

  • We will Inventor software to create our first design and then send it back to the people that we have surveyed to see if that is what they want or meet their requirement. Whatever the feedback that we got from them, we will develop our design of the product, and when our customer feel like that is what they want, then we will use 3D printer to create our first prototype.

Refine, modify, and perfect

  • After listing all the advantages and disadvantages and checking our first prototype, I might need to discuss with my team to come up with a better design as well as the better use of materials (based on what the customer want)
  • So as a group, we have come up with new design, we will:
    • Use wood to create the lid of the machine
    • Use iron to create the handle
    • Use plastic (by 3D printing) to be the foundation of the machine
    • Use iron to be the whole

Post-implementation review and assessment

  • After we all come up the new design, we will distribute our product (for free) to as many people as we can in order for them to test out and let them give us feedback so that we can make more changes until we need our customer’s criteria. Moreover, if there are any changes toward our design, we will go back and check some steps of our design process and see if there are something we could improve from.   


Engineer Biography – Lillian Moller Gilbreth

Society believed that only men can become an engineer, even in the contemporary world. However, Lillian Moller Gilbreth has proved that wrong; known as “The First Lady of engineer”, she has positively influenced the world.

Lillian got raised in an unconditional family at Oakland, California, with eight other siblings. She had a timid and introverted characteristic, which made her confronted so many difficulties in interacting with other people. Since those were parts of Lillian’s personalities, her parents didn’t allowed her to attend primary school until she reached nine, so Lillian was basically schooled home. As a very well educated woman, Lillian graduated from Oakland high school with outstanding grades. But one obstacle was that her father, William Moller, believed that it wasn’t possible for women to receive high education. In contrast, Lillian did not let anyone limited her dream; she then persuaded her father to let her commenced her college life at the University of California. She was determined and continued to achieve her bachelor’s and master’s degree at that same university.

Lillian didn’t get obsessed with one career, she was a woman with many specialties and based on her vocations, she was also known as “a genius of the art of living” in 1940s. Lillian was a phycologist, an industrial engineer, and an educator. With all of Lillian’s prodigious work, she didn’t work alone. She had married to a man named Frank Bunker Gilbreth in 1904, and had always been together for most of their career, especially in industrial engineering. The couple had 12 children together and had discovered their passion for efficiency and productivity in industry for their own house. Some examples of the partners experiments were to reduce the unnecessary motion and to present tasks, such as washing dishes and brushing teeth more efficient. Unfortunately, in 1924, Frank passed away but that did not let Lillian ended her path; she continued her occupation ever since. As result, Lillian had become the first woman professor in one engineering school, Purdue University, the first female who got selected to the National Academy of Engineering, and became the second woman to participate in the American Society of Mechanical Engineers.

Even though, Lillian was a mother of 12 and had to handle many other responsibilities, she was very committed to her work and was always followed her passion. For instance, she had invented two most recognized inventions: refrigerator shelves (egg keeper and butter tray) and foot-pedal trash can. Moreover, related to kitchen supplies engineerings, Lillian had also interviewed over 4,000 women in order for her to create the suitable height for stoves, sinks, and more kitchen materials. Overtime, because of Lillian amazing works, she earned over 20 honorary degrees and many prestigious awards, sucb hoover award. She was also got involved in American Men of Science, Who’s Who of American Women, and Notable American Women.

Lastly, without many contributions from Lillian Moller Gilbreth, many facets of today’s world might not be existed. Lillian and her husband had improved so many industrial materials or operations, which made life easier these days regarding to kitchen supplies. She had demonstrated to many people, especially women, that anyone can become an engineer, no matter how struggle their life was, they can always pursued their dream. In my opinion, I think Lillian had a very interesting life story to deliver. But independent, determined, and  flexible are what I wanted to describe her as. Lillian had performed her strength that she don’t need any help from anyone although that person was very important to her, like her husband. Lillian became even more successful when she was independent. Rather than that, Lillian’s flexibility had presented in many situation. One example for that was when she surveyed many women about kitchen materials, so during that interview there must be a lot of ideas or changes that came from different people. Of course Lillian can’t fulfil everyone’s desire but at least she manifested her best work that would somehow satisfied people’s need; she also adapted toward any transition of any prefered designs from different women that she interviewed. Similarly, regarding to her careers, Lillian was a very determined person. She had never wait for an opportunity to come to her but instead, she ran into that opportunity and was always followed her passion and endured so many hardships, whether it was about her family or society controversy.


The Network | Performing

This term I am in an exploration called Performing. So basically, based on the name, there is a play called The Network that will be performed by our team. The Network is a play about how people are interacting inside the network and how it could give negative effects to them. Most of the members in our class was assigned to a character in a play that they will present, however, there are also non-acting role to work on: marketing team, fiance team, sound team, snack bar team, and sponsorship team.

I was in the marketing team; my job is to create a Facebook page about the The Network and design a posters for the play. Personally, I do faced many challenges: fixing the poster’s design multiple times, communicating with the sponsor team in order implement the sponsor logos on the poster, and updating the Facebooks’ posts for everytime there is something happening in class. However, at the end I did overcome these obligations.

On the other hand, beside acting and working on non-acting roles, we are also playing some games that could help to improve our acting skill. We enjoyed and learned a lot from those games.

Here are the pictures of what we did during class time.


Bambujaya grade 3

For the last round exploration I was in Bambujaya grade 2, but in this round I was in it again for grade 3 curriculum. As mentioned in the previous post, Bambujaya is a private school targeted Cambodian kids using Khmer curriculum. They hired some students at Liger to write add-ons for Khmer curriculum that will be used for the students. When I was in Bambujaya grade 2, I was written add-ons for social study and Khmer book. However, in Bambujaya grade 3, I am currently writing add-ons for math curriculum. From day to day based, it took me longer time in thinking of new activities as well ideas to write, since math is more complex and require a lot of thinking.

In term of writing those add-ons, on 9th of March, 2018, the Bambujaya people had invited all the students who had participated in Bambujaya exploration from all three grades to visit the school’s location. After I heard this news I was very exciting because instead of imagining the place of the students learning, right now we got the see it live. In addition, maybe it might be different from what we expected as well.

In fact, seeing the progress of the school made me felt ready to start primary school again because it looked very modern and most importantly was the curriculum with new with hands-on activities and more engaging for the students.


To Spray or Not to Spray

What do you do when insects are disturbing you? At Liger we use insecticides to spray at our campus, once every two weeks. However, this year there is an exploration called To Spray Or Not To Spray. Basically, what we want to know for Liger is that should we continue to spray or stop, and what we have found out is that, Liger will be continue to use insecticide but with cautions and regulations, because those substances gives a harmful effect to organism and Environment, but if we don’t use them those insects will irk the students and we could get diseases from them as well. Until we have come up with this conclusion the 12 of us in the exploration did a lot of research by going out to field trips such as, agrochemicals shops, farmers farm, CEDAC, which is an organization that work with farmer to help them to become an organic farmers, and Kratie, to learn more about pesticide, as well as the chemicals that is commonly used and its effects.

Coming up with a conclusion about spraying chemicals in the campus is not only our final products. We have decided to create a magazine for people, and our target audiences are Ligers’ students. Each of has wrote an article about something that we have learned in class and that they are passion about. My article is called Banned or Band, it talks about the banned chemicals that have been banned in Cambodia and also in the other countries.

Here is the link to our magazine. 


Climate Summit

Climate Change is a global issued where everyone in the world is concerned about. So, in this exploration, we learned about Climate Summit. However, there is one program called World Climate Simulation. It is a program where people in different places came together and negotiate about Climate Change.

Our goal in this exploration is not only to learn about how does the World Climate Simulation works, but actually running the program with other people too. We have invited three schools and two organizations to come to Liger to participate in the program that we lead. We also went to Koh Seh, an island located in Kep, to learn about the ocean as well as climate change; we did a lot of snorkeling, beach clean up, and different experiments related to the ocean. It was a prodigious experience I had, and I really have a blissful time there.

Iron deficiency

We are learning about anemia that include iron deficiency. For most of the time in our class we are doing the research about it. We found out that Anemia is the most common diseases in the world. Anemia is when the level of our red blood cells lower than normal. The symptoms of it are weakness, pale skin, tired, headache, and more. That is because we don’t have enough iron in our body. But as we learn through the concept there is a simple solution and that’s called Lucky Iron Fish. Lucky Iron Fish is the organization that make the fish from the iron and can provide more iron in there body. Lucky Iron Fish came from Canada and now it almost make another organization in India. A man named Davuth who work with that organization had came to our school and tell us more about the organization. We had plan to Siem Reap to do the workshops to the villagers about anemia because we know that most of the people that live in the rural area got less iron in their body that can cause them a disease. But before we do it we need to plan what we going to tell them and learn more it clearly so that when they ask us the questions we can answer it confidently. We work together in a group and come up with four different parts of the presentation of the workshop and in total we did two workshop. The first group act a role play that talked about a woman that got anemia. Second group talked about the three time anemia that include iron deficiency. The third group talked about healthy eating, the meat and vegetables that contain a lot of iron. The last group talk about the Lucky Iron Fish, where it come from and how to use it. After all the presentation we did the demonstration to all the villagers, where we cooked one soup and then put the Lucky Iron Fish in it for ten minutes and then we let everyone taste that food and we found out that the taste of the food still the same but it contain more iron than before. In total we distributed the Lucky Iron Fish about 200 fish to the villagers. For the whole trip beside our workshops days we also take our opportunity to go to other place in Siem Reap. We went to Angkor Wat, hiking, landmine museum and to see the amazing circus. We had one Khmer teacher from our school came with us so when we went to any places he always tell the history about it to us.

  • Act a role play of the first workshop.

Chili Sauce Business

Every student at Liger had been participate in the Chili sauce business. There are four round of the exploration. I was in the last round. We made chili sauce. Our added value were: it made by the students at Liger that are 13-14 years old, 100% Cambodian product, and we only use Cambodia ingredients such as Kep sault, Kompong Speu palm sugar, kebab and all the fresh vegetables. In the class we divided into four team. There account and finance, outreach team, advertising, and product development. The account team work on the budget that for our chili sauce and calculate all the expenses. Outreach team worked to find the places that we can put our chilli sauce and sell it there. The product development team was making the chili sauce and they tried really to get the right ingredient and have good taste. The outreach team had went to many places in Phnom Penh to make people agree to put our chili sauce at their place. Most of the store won’t agree with us because they kind of not trust us and think that we are still young so we may not be a good partner with them. The accounting group also have problem with their work because they had calculate the number wrong and had messed up a lot of things. But for the advertising group not really have a lot of problems and they always keep update the information about our exploration on the social media (Facebook). But then we found out that our business is not success because we had not even reach to our break even point. The account team found out that we need a lot of money to start this business and we can’t make it. There is one restaurant that like our chili sauce and they had bought from us some. There is also another place that we can put our product in and they also email to us and ask about the time for when will we put our product at their place. But then we just tell them the truth that we can’t continued this project anymore because it only last for seven weeks and this is the last round too.
