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.

Khmer Literature Festival

On Friday 24th May, 2019, I had participated in an event called Khmer Literature Festival; it was the first day of my life as a student at the Liger Leadership Academy that I saw delightful smiles worn by all the event’s participants. Throughout decades, Khmer Literature Festival was known as the day where everything about Khmer literacy as well as Cambodian culture being shown: Khmer dance, Khmer traditional games, Khmer fashion show, public speaking, debates, poem writing, Khmer’s slang phrases, and etc. Although organizing an event  brought us to face so many difficulties but after all, it was worth the effort everybody had put in.   

Internship at Icing Living Decor

Although my dream career is to be a bioengineering specialist, but interior design used to be something that I always been interested in. Overtime, due to the intensity of interest, my school counselor and I figured out a plan that is capable of determining if my passion for interior design remained the same or vice versa: I got a one-week internship on interior design at Iching, furnitures and design company.

Here are some pictures that capture everything I did during my one-week internship.

I went on site to check the places as well as furniture that designed by Iching. 


Percent Yield

One of the topics we learned in Chemistry this term was about percent yield. Percent yield was about how much we made, using the amount that we could make, and was formed with the relationship of theoretical yield and actual yield. Theoretical yield was the amount that we expected to get, and the actual yield was the amount that we actually get. Therefore, to calculate percent yield, we would take the actual yield divided by theoretical yield and times everything by 100. Noted that the actual yield will always be smaller than theoretical yield, based on the definitions of the two words, this idea makes senses; some amount of something that we expected to get could be greater or smaller than the actual amount, however, talking in terms of producing product, for example, rice, farmers would most likely predicted that their farms would give them a very high quantity.

To get more in depth about percent yield as well to understand better about this topic in particular, we also did a lab on percent yield. We made smore using some ingredients/reactants that we were given. It was a very enjoyable lab because at the end, each of us got to taste our smore! For more details of the lap, check out my lab report (link below) that I worked with my other two friends. 




Critical Teen Issue

In critical teens issue exploration, we are focusing on how do teens cope with the pressure in their everyday’s life. The four main areas that we think teens are receiving the pressure from are partners, peers, parents, and society, and the theme for this particular round of exploration is healthy relationships. The goal of this project is to create a workshop about healthy relationships for teenagers in high school because we think that in the government school, students don’t get that much exposure to consent topic and other lessons that are about relationship.

For us to know exactly what teenagers’ issues are, we have sent a survey that is about different types of relationship to all the students at our school. By doing so, we have a better understanding of what their issues might be so that we can develop our workshop for the other students based on the data we received.

Here is the survey:

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.


Poem – Teenagers

In Khmer literacy class Liger senior students had published a poetry book. All the masterpieces (all the poems) were done by Liger seniors’ students.  I wrote two poems one was about school and another one was about teenagers. 

Teenagers poem talked about how teenagers these days obey their parents and that each of them should rethink that they received what they had today because of their parents; so even if they can’t look after them yet, they also (teenagers) shouldn’t hurt them.

Unit 1 Exam

1.) What is the difference between a qualitative and quantitative observation?

Qualitative observation is where we only need the meaning, concepts, or the characteristic of what we are observing,

Quantitative observation is where need mathematics, numbers, statistic..etc, in our observation.

For example: qualitative observation  → The water is very cold.

For example: quantitative observation → The water is approximately 2 degree Celsius.

2.) Ellie realizes that all of her plants die within a few months of her care.  She wants to check the effectiveness of fertilizer. She gives 6 plants in group A fertilizer, and 6 plants in group B no fertilizer.  She then measures the growth of the plants to see if the fertilizer helps them grow.

What is the control group? 

6 plants in group B with no fertilizer  

What is the experimental group?

6 plants in group A with fertilizer

What is the independent variable?

the effectiveness of fertilizer 

What is the dependent variable?

growth of plants

3.) What is the difference between precise and accurate?

Precision is (when you’re doing an experiment) how do you get the same answer when you’re using the same method, while accuracy is how close you are in getting to the correct answer.

4.) Convert the following numbers to scientific notation:

  1. ) 0.00432 → 4.32*10^-3 b.) 34500 → 3.45*10^4

5.)  If you measured the area of something that had a length of 5.0m and a width of 3.456m, how many significant figures would be in your answer?

The answer should have only 1 significant figure and with the rounded value because the fewest decimal place in the problem has only one sig fig

For example = 5.0*3.456 = 17.2800   but since the fewest decimal place in the problem has only one sig fig, the answer should be 17.3

6.) How many significant figures are in each of the following measurements?

  1. 3400 cm → 2 sig figs
  2. 0.00043200 L → 5 sig figs

C = K- 273      

7.)  If a thermometer reads  340C, what would the temperature be in Kelvin?

C = K-273 → K = C+273 = 34+273

= 307 Kelvin
