How does Smog Affect Brain Development?

In our chemistry class, I had a project to design my own question and research project on smog. So after I did a small research, I want to do something about the impact of smog on human health so I decided to do further research about the effect on human brain development. I found some interesting study that has been done in the west. One of the studies concluded that there was a correlation of exposing to a high fine particle could decline a person cognitive performance. 

The Rent Collector Art Piece Reflection

 In my literacy class, I was assigned to read a book called “The Rent Collector”. The book was very inspiring, it is a true story about a family who lives in the landfill and fights against the obstacles every single time to survive. Their main source of income was from collecting trash but with an opportunity to access to literature, it had changed their life forever. This made me realized that literature is everywhere, with enough determination and persistence the impossible will be possible. 

An inspiring art piece of how I felt after reading “The Rent Collection.”

World Poetry Day

On Thursday, March 21 it was the World Poetry Day, so my literacy essential class I was performing a short poem to my classmates. I was so proud to be a part of the day and most importantly, it had opened me to a window to express my feeling and reflect myself through the writing about myself in this school year.  I think this was one of my favorite poems so far that I wrote and it was inspired by my action this year to get out and engage more with my world. 

Let Fight to Shine Your Light
by Mengthong Long

This is your world, it belongs to you,
To you, to you, and to you all.
You own it! You were born with it! You commit to it!
This place is the reason why you are here.
So why not, taking responsibility to engage with your world.

Be yourself, believe in yourself, and go with your mind.
Let shine your light out there, show your truthfulness of who you are,
Show of what you capable of.

Let’s go out there to explore your own world.

No pain, no gain
No failures, no success
Actually, there is no such thing as failures
Because true failures is a lesson.

Dip Dip Boom Boom, the heart is beating, the sound of anxious.

We all have fear, we all used to undergo an uncomfortable situation.
But remember this:
Don’t let it build a cage around you.
Don’t let it hold your back
If you stuck, if I stuck and if we all stuck, we all are not growing.
We’re being locked in this boundary, in the darkness full of fear and doubt.

Fear is the mirror to reflect failure.

So let stop the FEAR to define you.
Let break the boundary; Let shine the life that you want to be.

Let shine your light!
Let shine your light!
Let shine your light!

If not here, where? If not now, when? If not you, who?
Have a taste of the flavor now or never.
Bravery is the only key to success!

So let shine your light right now!
Show this world of who you are.

Note: So please repeat these phrases after me.
I’m not scared!
I’m not scared!
We all not scared!

I can do it, we all can do it.
I’m gonna shine my light!
I’m gonna do whatever it takes to be fearless and to be who I am.

 

The Concentration of Phosphate and pH Chemicals in the Bassac River, Cambodia

This school year, I have a yearly research strand project that will be a focus on the concentration of the chemicals in the Bassac River, I will only focus on Phosphate and pH chemicals for now. I think this project is very crucial for Cambodian citizen, especially, the community that lives around the Bassac River because they all get the water from this river. Therefore, the community could be at risk due to a high concentration of the chemicals. So this research would allow us to confirm the quality of the water and whether it is safe or not for people to use this water for their living. Recently, I had a trip to Resource Development International (RDI) to collect the bottle samples that will be used to collect the water sample. In addition, I will partner with them to do a chemical analysis for my water sample. Lastly, I expect that the research project will be completed before the Khmer New Year.

Here is my research proposal: https://docs.google.com/document/d/1cjuAtxUxIFPrOgpWHW2_ORNu9htRcp3zLx17ZyGdCmk/edit

College Preparation

My graduation date will be on June 2020, so college isn’t that far from me where I am now. In the literacy class, we had learned about writing a formal email, create our own resume, and doing a college interview. We had written a formal email to a fake company that our teacher made it up, my email was about asking for the internship opportunity in the company. I had a chance to read my classmates writing to learn and giving feedbacks. We moved on to another subject which was writing our own resume and doing a college interview. It was my first resume writing, I got to learn about the structure while also show cast my projects in the writing so that it stands out from others. Lastly, I had a college interview simulation with one of the volunteers here, at Liger. The interview was formal, I needed to dress up nicely and be prepared for the questions from the administration. After experienced all of this, I felt more confident to reach out to people but as well believe in myself to persuade and sale myself during the interview.

First Statistic Class

This school year, it was my first class for introductory statistics which sound really complicated to me, as a student who has no idea about this college-level subject. A statistic is nothing connected to algebra, it’s another level of math which requires dot-connecting, analyzing, and comprehension skill to understand and extract the knowledge of new concepts from the statistic books. The correlation coefficient (R) is one of the hardest and exiting unit so far from the past two months of learning in this course. We learned to look at different scatterplots data and a linear regression line to understand how does the explanatory and response variables correlate with each other. Using the correlation formula to calculate the R-value is impossible and it kind of wasting our time. So calculator features come to be really handy to run the the two-variable stats, graph the scatter plot and calculate the linear regression line’s equation. Our group had sent out a survey to ask the students and facilitators for a data sample that we could use to find different the correlation between the two variables. I was involved in finding the correlation between the number of siblings versus the number of friends on Facebook. I really enjoyed learning about the statistic since it isn’t just about a number but it taught me to be a better person to be able to analyze data and make a good usage out from the skill.       

Cellular and Molecular Biology

The second unit 2 of our Ap Biology course was mainly about a cell. From my background of learning at Liger for 6 years, I exposed a lot to the science field related cell. For the introduction part of learning about each organelle’s function was mainly review. However, after completed the cell unit there were so many exciting concepts that I enjoyed learning about. The new concepts that I enjoyed learning the most were the signaling transduction pathway, cellular respiration, fermentation, and photosynthesis. Cells are smart and really complex to understand, especially, the concepts listed above. But how each processed form was really unique and precise. For instance, the process of signaling transduction pathway is that in order for a reaction to happen it requires a different step; the ligand has to bind with the protein receptor which creates another process of reaction. And the process in the transduction will continue to create another reaction until the final step for the cell to response the signal. At the same time, we had a minilab of fermentation. We set up an experiment of yeast and different sources of sugar and placed it together in different flasks. After two hours of experiment, I saw the ballon with air inside which was carbon dioxide. Furthermore, we had another mini lab to understand the concept of photosynthesis since one of the product from the light-reaction was oxygen. So for our experiment, we set up a leave inside the water and leave it under the sunlight. It turned out the lab was working, I was surprised when a small so many tiny bubbles which indicate the oxygen as a waste product from photosynthesis.

 

Doing Labs Help to Understand New Concepts in Chemistry Course

Over the past few weeks in the chemistry course, I had continued and built up my knowledge on this subject area. We had been learning about bonding, Lewis structures, VSEPR, balancing the equation and calculate the limiting reactant. There were so many new concepts that I sometimes found it hard to catch up with the class, however, with a lot of practices on a worksheet on the unit and doing a few labs those new concepts had become easy to understand. For instance, I did a lot of determining the bonding by doing two different experiments. The first one was Solubility in water where we placed different substances into the water and base on the reaction and the bonding characteristics we could determine the substances bond. The second lab was melting the same substances on fire and also determine its bonding. In addition, we recently had another lab where we made out own s’more and we used the concept in the lab to understand and practice the concepts of balancing the equation and determine the limiting and excess reactants in our lab. I these mini-labs because I enjoy learning and visualize the new concept I had learned in the course of chemistry.

 

 

Business Model Competition Update (Chek Rom Lek)

This post will be updating about my business model competition with the Chek Rom Lek project. After our hard work doing our business validation with authors and students we had finalized our idea. Chek Rom Lek is an online sharing platform where students and researchers can conveniently access resources (reports and e-books) in the Khmer language. As a team leader, I was able to drive this business idea and my team into a final round of the competition. We were able to present this idea in front of nine judges and a few hundred audience members. I was proud of my team and all of the positive spirits that we all kept going to push forward. But the most important thing was the exposure to try out new experience and overcome the challenge. The lesson we gained from this project was a phenomenon, it was just a starting point to exploring in the business world. I can not wait to continue Chek Rom Lek project and help to improve literacy education in Cambodia. 

BMC Competition 2018 Application

Over the past seven weeks, we had been working to brainstorm some ideas that would be possible to submit it for the BMC Cambodia 2018 competition. At the same time, Keith had taught us different ways to look at the problem and find a solution for it. In addition, he had to get us to expose to previous year application and their video. I had come up with the pain of students finding a hard time accessing information in Khmer language resources. I had brainstorm the pain and the solution and collaborate with my team to create a 3 minutes video to submit for the competition. Visal was helping me with the script and Kimseng was our filmmaker and editor.
