During this sixth school year, I studied Creative Technology; Before, I really hate coding and studied javascript. I have no idea of how to code, and what is variable, what is an event, what is a function, and what is an object. This is an astonishing year, which I really like to learn how to code, I can code anything I want. Besides, all those codings, we have a project which is to build a fast robot and compete with other Liger teams. Although we are focusing on coding, we also learned how to 3D design and prints different parts of our robot. Moreover, we learned how to connect breadboard to Arduino and to objects by using the wires. So by the end of this expertise, my goal is to get a better understanding of coding and javascript.
Khmer Dance
Beyond having the Extention on the weekday, I decided to join the weekend activity which is called Khmer Dance. In this activity explicitly, we learned difference type of dances that our ancestors had retained for us. There is a history which the dances were disappeared during Khmer Rouge regime, which the Khmer Rouge leaders decided to kill all the dancers in Cambodia. But luckily there is a woman, after Khmer Rouge, trying to learn and preserved those dances for us, the next generation. Khmer Dance is a special art for ancient Khmer to express their feeling to others.
Football Training
Besides studying in the classroom and passionate about science, I really like to play football. I had joined many football activities every term including the Extension on the weekday and the activity on the weekend. Above and beyond training with the coach, I’ve been playing football in many competitions with other schools in Phnom Penh. I really love to play this game, it makes me to work as a team, to be healthy, and to reflect critically of the form I play.
Narrative Essay
It Began With the Paper
“Why do I have to do this?” It was the mid-year of my grade five curricula. This was not what I’ve learned in class, now I have to do this? I should be sitting at my table with friends and enjoy the break, so why do I need to come here and do this? It’s only a piece of paper, can it change my future or my whole life? Will I pass the test? Will I get the scholarship to this mysterious school? The bell ring, time is up and then it’s the last chance for me to finish up the paper.
This is the personal narrative that I been working on in literacy Essential. This essay is about the coming of age experiences, all of the Liger students have different coming of age situation.
Khmer
Along with English practicing school, we also have Khmer in the curriculum. In this 2017-2018 school year, specifically in Khmer class, we are focusing on writing and researching the information to present in front of the whole class. Within the first term of the school year, we’ve been researching the information about Pchhum Ben, which is the Buddhist tradition festival that occurs every September and it lasted for 15 days, during the rainy season in Cambodia. So, every citizen needs to make food to offer to the monk at the pagoda in order to direct all the food and merit to the ancestors that already passed away. The research attached to this link: Here.
Physic
After an annual paucity of physic, we finally evoked this significant topic into our Essential. After a full understanding about Newton’s Laws, currently, we are focusing on Static Equilibrium, frictions, and inclined plane. I’ve been going through many exercises in class, as well as the coefficient of static friction lab. This is legitimately important to Liger’s students as well as me.
AP Statistic
This is the first ever time, that about a half of Liger Leadership Academy students are studying AP Statistic. This advanced program is really difficult for me, I need to manage my time to read, to do the problematic exercises, also to do other assessments. Already stated, I need to be an initiative to seek out for help from the teacher as a consequence finding practices from other useful websites such as Khan Academy. Besides, I have many challenges to study this course since it was in the second language for me. So by the end of this year, this 15-years old boy’s goal is to take the actual test and pass it, in order for me to have a better education in university or college’s courses.

Dinosaur Investigation
In the first exploration in the course of 2017-2018, I studied Dinosaur Investigation. First of all, we knew that there a footprint site in Battambang province from the Department of Geology in Ministry of Mine and Energy, Cambodia. This is the new topic for me and for my team. As it is a new topic for us, it quite difficult for us to do field methodology including casting and identifying the footprints. Our team spent a day walking around the area to do field method for possible footprints such as taking notes, measuring the length and the size of the footprints, identifying rock type and recording geographic coordinates and elevation. We then used clay and plaster of Paris to make casts of the footprints for more investigation in class. Besides doing the casts, we interviewed some people around the area whether they believe in dinosaurs and it turned out that they didn’t believe that dinosaurs existed. We had recorded about 15 difference footprints on the site by dividing the whole big site into four smaller sites call A, B, C, and D.
After this inconvenient day, we finally cast from the prints that we think it is dinosaur’s footprints. After having all the casting, our next immense goal is to validate our footprints by writing our own report. Therefore, we created a report that contains all of the information such as, the site and the landmark and the footprint itself, in order for us to send this report to other experts. So, we then worked with five paleontologists around the globe to validate and help us on the footprints that we have discovered.
Through working with other paleontologists from around the world we managed to validate our footprints and it turned out that some of our footprints are actually the real dinosaur footprints. So now we need to work on preservation and distribute all the information to Cambodia and all around the world.
Saltwater Battery Investigation
Project Name: Salt Energy Battery
Your Name: Panharith Yav
Question:
What are the elements can be used to create the saltwater battery?
Background Information:
The electrical battery is the devices that made out of one or more electrochemical cell which is a device that necessary to generate electrical energy or facilitate the chemical reaction to generate the energy. Nowadays, batteries are really common daily in used for flashlights, phones, cameras and many other electrical suppliers. Moreover, there are two terminals on the batteries which are the positive terminal called cathode and the negative terminal called anode. With the electrolytes inside the battery, it allows the cathode and anode to exchange the ions when they move in one direction as they deliver the electricity and it will recharge when it moves to another direction. Currently, the batteries that people use daily are really effective to the environment when they throw it away. So, now people are trying to discover a new type of batteries that have no damage on the environment and sustainable for daily life uses.
Salt Water Battery:
Saltwater battery is the battery that has salty water, copper, zinc that attached to each other in the cup. With normal fresh water is very poor to the conductor of electricity but if we add salt into the solution it’ll become an electrolyte solution that can conduct electricity. So by adding salt to the pure water, when the salt or sodium chloride dissolved, they separate into different electrically charged atom which is called ions; when the salt is dissolved in will turn into the positive Na (sodium) ions and the negative Cl (chloride) ions. Additionally, electricity work through the negative charge and positive charge in the battery. Normally, we use copper wire in the electrical product; copper is a type of metal which it can conduct electricity really well. Zinc more readily to loses electrons than copper, so if we place zinc and copper metal in solutions of their salts can cause electrons to flow through an external wire which leads from the zinc to the copper. So in the middle of the solution, we can place a LED light to test, you will see the light is gleaming.
Hypothesis:
The zinc will lose their electrons to try to balance their atoms, so the copper will receive the electrons from zinc which in that process there is electricity between both of it.
Experiment or Design:
To design this experiment first we need five medium-size beakers, six alligators clips, five zinc coins and five copper plates.
Step to Build the Experiment:
Step 1: Filled the beakers with 200 mL of fresh water each.
Step 2: Add 3 tablespoons of table salt to those beakers.
Step 3: Connect the alligator clip one side to the zinc coins and another to the copper plate.
**(Make Sure there a clip connect to only zinc coin and another connection to only copper plate)**
Step 4: Place the coppers plates and zinc coin in the beakers (in one beaker there should be one zinc coin and one copper plate that not touch each other).
Step 5: There should be one beaker with the only copper plate and one with only zinc coin so place the remaining copper and zinc to the beaker where it missing.
Step 6: After placing the two remaining component there should be two sides of the alligators clip left.
Step 7: Connect the two side of the alligators clip to electronic devices such as LED and voltmeter to find how much the salt battery can conduct.
Data Charts:
The data show that when we added more salt into the water the voltage is increased at the same time.
Results:
According to the data above, in the result, the salt water battery is able to conduct a small amount of electricity. The graph shows that the voltage is increased over time when you add more salt to the water. Moreover, after the voltage is increasing it often falling back for example in about the 22 seconds the voltage is increasing but look at the 27 and 30 seconds the voltage is falling back. Even though this is a few voltages that the salt water battery had conducted, you can say that if you were to design it on a larger scale it may run for a whole house or classroom light. Additionally, if you look at the LED light that attached to the solution you can clearly saw that it actually glow. So when zinc loses electrons and the copper gain one, and if we place zinc and copper metal in solutions of their salts can cause electrons to flow through an external wire which leads from the zinc to the copper. The electron that flows from zinc to copper will create the current and will to be electricity.
Conclusion:
The graph result shows that the voltage is increased over time when you add more salt to the water. Moreover, after the voltage is increasing it often falling back for example in about the 22 seconds the voltage is increasing but look at the 27 and 30 seconds the voltage is falling back. This clearly shows that the salt water battery is working and we also saw the there are some amount of voltages. Moreover, we can see the pattern when the voltages were going up and falling back when and after we added more salt into the solution, According to the result and the data distributed we can say that the result strongly supports the hypothesis up above. Additionally, the result means that the topic of salt water battery should be the next focus for scientists who try to develop the green energy. Besides, this experiment is on a small scale so the result doesn’t really affect the people perspective on using the salt water battery but if it were to be a larger scale it would of do so. So the next plan is, how can we develop salt water battery into a larger scale and when are we able to do it so?
