S’mores a delicious snack yet, a snack that can be used to showcase chemistry principles. One of the principles that can be showed is limiting and excess reactant. Besides learning about this concept in the classroom, our facilitator created a small lab to strengthen our knowledge of this concept. The objective of the lab was to make s’mores while calculating the limiting and excess reactant within the ingredient we had: chocolate bars, cracker, and marshmallow.
Similar to Math, this term we are focusing on SAT. Since most of us are having trouble reading historical passages from the SAT, our facilitator assigned an article about America history, from CommonLit, every week and we try to analyze it together. We choose articles related to America’s history because most historical passages from the SAT are based on America’s history.
Due to the fact that English is our second language, the style of writing, the languages the author used back then were very challenging to understand.
Since last year, we had been writing poems about different topics and the start of this year, we started to conduct all of those poems into a book. With students who were working on editing the book, editing the poems and do writing pieces, the book came out well and made its first debut at the Khmer Literature festival. A poem is a way of communicating or expressing one’s idea through writing or dictating in rhymes and rhythm. It was a feeling of sensation and nostalgia when reading some of my friends’ poem.
In math this term, we have been grinding hours in practicing the SAT for the SAT test on October 6th, 2018. We had two weeks of SAT intense boot camp at the beginning of the school year to prepare ourselves for the test. But, before the test come knocking our doors we have time to practice; personally, the only way to be confident and be comfortable with the test is to practice. Since SAT is one of our tickets to getting a good university, I need to sacrifice my time, even if it means I have to pause playing Fortnite, and avoid procrastination and practice the test facing it head-on.
For the past few months, we have been exploring the basic of Chemistry through labs and lessons. The highlight of the unit was the Flame lab test. The objective of the lab was to see what color will the flame emit when putting different chloride into it. The compounds that we were experiment with were, Barium Chloride, Calcium Chloride, Copper (II) Chloride, Lithium Chloride, Potassium Chloride, and Strontium Chloride. But, the main purpose of the lab was to understand the energy level. I really enjoy seeing those wonderful colors and also mesmerized by the quantum mechanic behind it.
How Black Panther’s suit work?
Marvel mentioned that Black Panther’s suit made out of a fictional element called, “Vibranium.” The only fact we knew about Vibranium is that it has the ability absorb and redirect kinetic energy. But how can Vibranium absorbed and redirect kinetic energy?
Let’s say someone is shooting at Black Panther. Now, the bullet that came out of the gun is moving and it has some momentum. So, the mass of the bullet is moving at a certain velocity in a certain direction. What’s more? The bullet is in motion and loaded with energy; we describe energy in motion as, “Kinetic Energy(or KE).”
When the bullet impact the suit the energy has to go somewhere as the law of conservation of energy stated, “the total energy of an isolated system remains constant, it is said to be conserved over time and energy can neither be created nor destroyed; rather, it can only be transformed from one form to another.” So where do all of the energy go? First, let’s look at what type of collision between the bullet and the suit.
For elastic collision, the kinetic energy is conserved but for the inelastic collision, “kinetic energy is not conserved due to the action of internal friction.” In our real world, there is no elastic collision (at least within our human sight). So, the collision between the bullet and the suit must be an inelastic collision.
So what happened during the collision? Well, the suit would bend or deformed even on a microscopic scale and it would take energy to transform into another form of energy to do this. In our world, “It takes energy to physically change or deform some material and most of that energy is lost through internal friction or that material’s atoms.” What if Vibranium could absorb and store KE in the deformation. Let’s take a peek at a spring. If we would push the spring, it will be compressed in some distance. To compress the spring it would take some energy and where does the energy go? The energy would be stored in the compressed spring as elastic potential energy. What if Black Panther’s suit is made out of billions of billions of billions of billions of molecular springs using Vibranium’s atom. Every impact the Black Panther experienced, the springs would absorb all of the kinetic energy and store it as elastic potential energy.
Anyway, one thing that we didn’t consider is the reaction of the object that Black Panther applies the force to. In Newton’s third law of motion, “For every action, there is an equal and opposite reaction.” So if Black Panther would apply some force to the car then he would have the same amount of force that applies to him. Take a look at this clip.
Even though the energy is not conserved, but the momentum is conserved. So the Black Panther would have some momentum toward him.
All of the above is possible in our physical world or at least in the near future but one thing that we unable to explain is, How can Black Panther release the energy at once? Could he have some button to press? This is the part where we uncertain about.
In this literacy unit, we are focusing on ancient civilization. Specifically, we were studying ancient Greece gods and goddesses. Based on this theme, each student has to pick a god, a goddess or a monster from the myth of ancient Greece. From all the list of gods, goddesses or monsters, I picked Medusa.
To depict information we had researched about the character we choose, we had to do some projects that encompass, research paper, character profile, discussion questions, etc.
In this post, I’m sharing my research paper about Medusa.
Imagine the power of turning anyone into stone with only a gaze. This lethal power possessed by Medusa, the Gorgon, who has venomous snakes as hair locks, skin with green scales and a hideous appearance.
Most sources described her as the daughter of Phorcys and Ceto the Sea Titans. She had two sisters, Stheno and Euryale, who were immortals but unfortunately, Medusa herself was mortal. Surprisingly, out of all, Medusa was the brainy one and her name indicated she was the queen of her sisters. Some sources claimed, Medusa lived and died on the island named Sarpedon. But some others claimed her home was Libya. During her life, Medusa vowed to celebrate her entire life as a priestess of Athena.
Despite the fact that she was a gorgon, she was the symbol of protection. She was on the breastplate of Alexander the Great. Even until today, two species of snakes were named after her. Most sculptors and vase-painter envisaged her as beautiful as well as petrifying. On the other hand, in feminism, she symbolized rage.
The legend of Medusa derived from many sources but mainly Ovid (the Roman poet). Her story goes, she was a priestess of Athena and her beauty was so captivating that it captured Poseidon’s heart. Unfortunately for her, she got raped by Poseidon in the Athena Temple that enraged Athena who then cursed Medusa to a hideous gorgon…
Who once had gorgeous hair that intoxicates men.
Who once has pure white milky skin that reflects any light.
Who once has beautiful eyes that were very captivating.
Who once gorgeous, exquisite and beauteous.
As the story continues, Perseus, a demigod, decapitated Medusa and gave her head(that still possess the same power) to Athena who then put it on her shield as a protection.
Although Medusa was widely known as a hideous monster, she still earned her spot as a protector. What’s more surprising is the fact that she had her, “profile engraved on the coin of the reign of Seleucus I Nicator of Syria from 312-280 B.C”.

In my architecture independent study, I found a 2D contemporary house on Google and try to replicate it in 3D. Soon after, I created a 3D model of it using Sketchup. In fact, creating my first 3D model was not easy, due to lack of knowledge and experience in the software I’m using. Although this was kind of challenging, I found some resources on the internet and managed to grab a few of the tips and tricks to get the designing processing flowing. Additionally, I’m planning on making the same model from paper materials just to see the tangible model that I designed in Sketchup.
Aside from my current project, I look forward to future projects as I’m trying to grasp foundation in architecture.

On December 2nd of 2017, a group of Liger students participated in a #bike4kids biking experience around the ancient temples at Seim Reap. For some, it was their first time but for some others, it was their second times. On a subsequent day, we also participated in a 10km run. Initially, we’re trained for the half-marathon, but due to time-constrained, we weren’t able to get enough training so we joined the 10km run. There were more than 5000 participants including 15 students from our school. Surprisingly, it took me 57 minutes to complete, which is what I didn’t expect because I expected I would run slower than that but most importantly, it was my first 10km run.
For this past months, we’ve been out to different tropical places around Cambodia. The purpose of doing so is to gather information about species of animals. But the primary goal of this exploration is to publish a book about different species of Cambodia animals. There also alternative ways of gathering information, such as online resources, experts, and printed resources. It took us about 6 months to publish the book. The paintings inside were originally painted by the Liger Leadership Academy students. Below is the cover of our book called, The Illustrated Guide to Wildlife of Cambodia
