## Khmer Literature and Culture Festival

Liger is all about project-based learning, so is our Khmer class. After publishing a Khmer poem book we decided to do something a little bit bigger to further promote the Khmer literature and culture. We put our though together and came up with an event that is going to be fun and will promote as many aspects of the Khmer literature and culture as possible. With 50 young-organizers planings and organizing, the event started to become real.

After months of preparation and planning, we’re finally ready for the big event. On the 25th of May 2019, the Khmer literature and culture at Liger prosper. Everybody dress up stunningly beautiful in the Khmer traditional clothes and filled with energy to rock the day with knowledge and fun. As the leader of the Khmer slang booth​(គ្រាមភាសា), I was rocking a Khmer traditional pant (ខោចែវ – khao-chev), and a white long-sleeve t-shirt with Angkor Wat image across the chest.

It was 9:00 am and the event has started. Students from many public schools, private school, and organization rush into every booth to see what do we have to offer. I was more than excited to have fun and teach about my topic. To attract the audience I’ve prepared something very special. I displayed a very appetizing snack on the table as the price for playing and learning about Khmer slang (គ្រាមភាសា). People gathering around my booth and very interested in learning and having fun with my topic. Loud laughs, huge smiles, and kind regards are what I receive from the crowd. I couldn’t be more proud. I am very grateful to take part in the great event and very honor in making the Khmer literature and culture prosper once again.

## Correlation – Statistic

Correlation in a statistic is a factor used to describe the relationship between one variable and the other variable. In a graph, there are two axes: X-axis (explanatory variable) and Y-axis (responses variable). For example, If we would use height to predict weight then the height would be the explanatory variable and the weight would be the response variable. Then we would use the data of the height and the weight to calculate for the correlation coefficient (r).

The correlation coefficient(r), rage from -1 to 1. When the r-value equal to -1, it shows that the two variables have a negative relationship/correlation; in this case, it means that as the height increase, the predicted weight will decrease. On the other hand, if the r-value would to equal to 1, the two variables will have a positive relationship/correlation which means that as the height increase the weight will also increase. Yet, if the r-value equal to 0, the two variables don’t have any relationship at all. However, a perfect r-value of -1, 0, or 1 is not a value that we’ll get calculating real datasets because real datasets won’t have such an exact relationship between real datasets.

The equation for r is r =1/n-1∑(xi-x/xs)(yi-y/ys), however, it would take forever to plug in and solve this equation; so we use the Ti3 calculator instead. In our case of using height to predict weight, we receive an r-value of .76. This value shows a high correlation between the two variables, therefore, it’s positive to use the height to predict the weight.

Watch me solving for the r and r-square value!

## Lewis Dot Structure and VSEPR Model

This round in chemistry essential, I have learned so many new concepts that manoeuvre me deeper into the world of chemistry. For instance, we were learning about the Lewis Dot Structure and Vsepr Model. These two concepts were very interesting to me because it gives me a better sense of how chemical bond together at the atom level.

Lewis dot structure is a diagram that shows how atoms are bonding together and how many lone pairs of electrons are there in the molecule. For example, if we have an element of Phosphorus trifluoride (PF3), we would start off by looking for the valence electrons. In this case, the valence electrons for Phosphorus and the three Fluorine is 5 and 21 respectively. Then, we would draw P (symbol for Phosphorus) in the middle of the diagram since it’s less electronegative with five dots (representing the valence electrons) around it. However, the dots can’t just be laying everywhere around the P: It needs to be placed on the four sides of the P (top, right, bottom, and left.) Then we need to define the bonding between P and the three Fluorine (F3). Since Phosphorus has three valence electrons, it only needs 3 more to get to the stable stage. Therefore, it can share its three individuals electrons with the other three individuals electrons from the three fluorine. So we can draw three lines from P to the three fluorine with a free pair of electrons on the top of P and 6 free pairs of electrons around each F.

Afterwards, we can also turn this structure into a 3D model using the VSEPR model. Since this diagram got three bonds with a free pair of electrons on the centre atom, it falls under the category of Trigonal Pyramidal.

## The Book of Khmer Poem

There are so many aspects that make Liger different from the public school one of those is the curriculum. At Liger, most of the class were conducted in English, yet we still spend 5 hours a week learning our native language: Khmer. Unlike the classes in public school, our Khmer class also have small projects like research papers and poems. At the end of last year, we started to write poems about any topic we like. Then now, at the beginning of this year, we decided to turn those poems into a book along with some research about the different type of poem and their history. After the book is finished, we have a showcase at the Khmer Literature Festival in Battambang province. Surprisingly, we got a lot of support: we sold out all of our printed books. After the showcase, we found out that there are some parts of the book that needs to be further edited before another showcase in Phnom Penh Book Fare in December.

## Future Food

Name that one thing that all human needed to survive, of course, food! Where are food come from? Well, agriculture is where most of our food came from. We grow a variety of food using soil and water. But as the population growing rapidly, we don’t have enough of those resources to do this old farming method. So what can we do? Well, we can instead of using soil, use a system called Hydroponic. Hydroponic is an agricultural system using sponge/perlite as growing median and water as the nutrition source. Unlike the traditional agriculture where we need a large space of land to farm, hydroponic is a system where we can install it in such a small space such as wall etc.

So basically we mix the water in our reservoir with nutrition solution, and as the water flows through the system, the plant will observe the nutrition and water to grow itself. Once the water flows through the whole raising bed, it flows back straight to the reservoir and ready to reuse again in the system. By growing produce in hydroponics, we can save both land and water which are really essential for our growing population.

So in an exploration called Future Food, we’re working on getting one of this new technique running so that we can supply the product to the main kitchen and for the senior cohort. In a group of eight students, I am working as a 3D designer for the project. So for any project, we need a clear plan on how things going look and how things going with each so I designed a 3D model of the whole system using a software called Inventor. One of the biggest challenges I face during this process is finding the exact measurement for all the parts in the system. The thing is that I started working on this project without any actual parts to measure, so I have to look through all over the internet for those measurements which take so much time. This challenge gave me a good practice in my researching skill, which is a really good opportunity to improve.

អ្នកនេសាទ

មើលនាយសមុទ្រសែនវែងអន្លាយ                             មើលទៅសែនឆ្ងាយដាច់កន្ទុយភ្នែក

អ្នកខ្លះមិនឃើញគុណតម្លៃនេះ                                   បែរជាត្រិះរិះធ្វើអ្វីមិនល្អ

គេបានបំផ្លាញសមុទ្របវរ                                            វើវាបន្តរដើម្បីកំរៃ

គ្មានអ្នកណាក្រៅពីអ្នកនេសាទ                                 ខំប្រឹងសង្វាតជារាងរាល់ថ្ងៃ

អូសអួនហើយឆក់ធ្វើយ៉ាងព្រៃផ្សៃ                            ទោះយ៉ាងណាក្ដីត្រីមួយកញ្ជើ

មិនមែនកំហុសគេទាំស្រុងទេ                                    នេះក៏ព្រោះតែឥការងារធ្វើ

ជារាងរាល់ថ្ងៃរាល់គ្រប់អំពើរ                                       គ្រាន់តែទ្វើដើម្បីក្រពះ

ជាចុងក្រោយកវីសង្ឃឹមថា                                         រាដ្ធាភិបាលនឹងប្រឹងជំនះ

បង្កើតការងារមុនថ្ងៃថ្មីរះ                                           ជួយដល់ក្រពះអ្នកនេសាទ

Translation

Fishermen

Look at the ocean is so wide

It looks so long out of my view

When I think about it make me feel sick

I just want to yell so the sky can hear

Oh ocean, Cambodian ocean

Thank you for your hard working

You do not sit still

But you work hard to attract the tourist.

But some people didn’t see this benefit

And they intend to do bad thing

They destroy the beautiful ocean

Do it more and more for money

There are no other than the fishermen

Trying hard every day

Electric Trawling brutally

However just a bucket of fish

But it’s not totally their fault

It is because lack of job

And every day, every action

They just do it for their stomach

At last the author hopes

The government will help

Makes more jobs before the new sunrise

Help the fishermen’s stomachs.

## Coming of Age – Personal Narrative

As a literacy assignment, our teacher asked us to write a two pages essay about our personal experience of “Coming of Age”. So I decided to write an essay about an aspect that made me felt like an adult; which is independence.

### Independent

Independence is the beacon to maturity. It took me about twelve years to gain my independence my family and the world. For twelve years, I was just a kid that only wanted to have fun. For twelve years, I lacked independence, bravery, and maturity. Ten years in a small world just home and school disrupts me from seeing the immense universe full of creative steps and dazzling path. Until one day I found an amazing place that helps me to have my position today.

I was born on December 10, 2002, in a village of Chumposka-eka. As the big brother in the family, I didn’t get as much attention as my brothers. I grew up in a family that valued education and encouraged me. At age five, my mom decided that it was time for me to start school. however, my first school was full of corruption and wasn’t a place I would go by choice. Time passed and I adapted. In fourth grade, everything changed. In 2012, my mom gave me a huge opportunity to take a test for a scholarship at Liger Learning Center. I was hopeless about passing the test because I had not been very successful in school. I remember back then in a class of forty students, I would be the thirty-third student. Nevertheless, the test for Liger was not the same material from school and I actually did pretty well on the test and received the scholarship.

Within the first two years at Liger, my mindset completely changed. I used to be this kid who’s doesn’t like school, doesn’t have many friends, and have really bad scores in class; Within the first two years at Liger, my mindset completely changed. Being independent is a massive challenge for me at first. Due to the lack of independent before Liger, I was really inept at utilizing my independence, but as I got older and worked harder, I became more adept. Project-based learning really helped me use my time more wisely.

When I was thirteen, it was the first time ever in my life, where I felt so much of the freedom from my parent. It was back in summer of 2016. In the middle of the break, I got phone calls from my Phnom Penh-Liger-friends inviting me to attend a small party with them. Those phone calls make me really happy since I had never been invited to any party by myself. However, during this happy moment, I had a feeling that my parent won’t ever let me out there by my own. Follow this thought makes me afraid to ask for my mom’s permission. Nevertheless, the energy of the party, the energy of wanted freedom, and the energy of friendship is much stronger than this small though. So I dispatch the fear and walk bravely toward my mom asking for her permission. For this first attempt, I was so happy since my proposal got accepted. Disputed the happiness and hide emotions was my idea, but I guess the stupid smile still leak out. Her permission is like a ticket for roller coaster ride through amazing adventures.

Finally, the party came. I was so excited for the day despite all the rule that was given by my mom, about what I should and shouldn’t do, that postpone all the fun thought that I had. The closer I get to the party the more I get pumped up. With eight people at the party, it was the best party yet I ever attend. After the party end, we decided to go to another place to relax with wifi and air conditioner in town. While walking through the town, I felt no longer as a kid. The level of independence I got at that moment is enough to change me. Then we arrived at the destination and having fun. Due to all the fun I had during the trip, I just realized how powerful is independence.

Independence is a key to unlock all of the characteristics leading to adulthood. Additionally there no need for the insanely huge amount of independence to become an adult. For example, within just a single trip that my mom allowed me to go by myself, was enough to unlock the characteristics of an adulthood. So I believe that independence is all we need to be an adulthood.
