Literacy Round 2

This round 2, I have learned so many things in Literacy class. Such as Like Learning about Social and Environmental injustice, Living in Landfill, History of Halloween, Debate on letter grade, devil’s advocate, and learning how to write essay.

In our Literacy Wednesday class, we have been reading a book that called The rent collector. The author is Camron Wright. This book was related to people’s life in Steung Meanchey dump place in Cambodia and it also related to Literacy. This book is really good because it touch me that Literacy is really important for us. Even though we live in the dump place but literacy can change our life. It’s kind of related to our lesson about environmental injustice because inn this story is talking about how trash affect our health and how many garbage that enter into the landfill everyday.

The Rent Collector

I’m really interested in debating because it’s help me a lot. Such as like helping me to know more idea of the other team why they choose to agree or disagree with that statement. It’s also help me to trying to find the solution. In future we are not only debating in our class but we could debate for best solution to our country.

For this debating, the statement was Schools should stop the practice of giving letter grades to students. Instead, they should only give written feedback. I was agree on this statement. 

Schools should stop the practice of giving letter grades to students. Instead, they should only give written feedback.

Learning something is not always depend on letter grades but it’s depend on what are you really get to learn in your class. Because if you are cheating, you just get the high letter grades and your learning is just going down. And you won’t study hard enough to get your own scores just sit still and copy other work. By the way if you get the feedback from your teachers or you facilitators, you will know what is your grade really is? Educators say giving feedback is gives parents more information about their child’s performance in the classroom.




Grades are preferable. They offer clean lines of demarcation between types of performance, types of student, types of future. They point us in a few clear directions. They tell us that a student needs help. They tell us a student has talent. But they don’t tell us how to help, how to IMPROVE talent, how to push students to be better.

Devil’s Advocate


After the debating ended, we have learned about devil’s advocate. Being Devil’s advocate is we are trying to argue with our idea because when we know what are the question that the other side will ask. So it’s easy for us to find the solution to fight them. In the lesson, we have so many topics. My topic is about Every society should follow the one child rule. For the first time, I was disagree with is topic but after I did some research I’m kind agree with it. Here some of my researching on Every society should follow the one child rule.

The Chinese government says that the One Child Policy has restrained China’s mushrooming population (claiming that it has prevented an estimated 400 million births since its inception in 1980).

  • If there are four children in each of your family how about the world, how many population?

1.Population Control. China is one of the most populous countries in the world, with its population over 1 billion. Without the policy, this number will continue to add up and this can aggravate the problem of overpopulation.

  • If there are so many children in your family, how can each of they get the jobs easily?

2. Job Opportunities. With the strict rule of One Child Policy, children who grew up during this period were able to find jobs easily since there will be positions available.  jobs will need to be filled in and the younger generation will be the ones to take the place of the available jobs.

  • If there so many children in your family do you have times for them or get them something that they need?

3.Better Life. Having only one children is having a comfortable life. This is because all the attention, love and financial resources of the parents will be enjoyed by the child. He or she will have the chance to get the best education, better health care and job opportunities.

Do you able to have enough sources for pay your children?

4 Incentives. As a reward for complying with the policy, Chinese parents who followed the rule they will apply for education loans for their children, longer days of maternity leave and housing loans. Without the policy, parents will not be able to take advantage of these privileges. (

I really love debating. It gave me a lot of information that I never knew before. I helping me to find the best solution on what we are allow or not allow to happen.

STEM Round 2

This term, in STEM class, I got to learn many things. We got to learn about periodic table, elements, alloy, chemical bonding, ionic bond, covalent bond, Polar and Nonpolar Covalent Bonds.


First of all we got to learn the history of Periodic table. Mendeleev is the one who organized the elements from left to right across each row, elements are arranged by increasing atomic mass. There are only 92 elements.

The original Periodic table.


Now, In Periodic table, there are 118 elements, those new 26 elements were just add by some new scientist. In the modern periodic table, elements are organized by atomic number.There are 4 group in periodic table: alkali metals, alkaline earth metals, halogens and noble gases.

The new Periodic table.

Group 1: Alkali Metals

All the elements in group 1 have just one valence electron, so they are highly reactive. The alkali metals are soft. Most are soft enough to cut with a knife. They are also low in density. Some of them even float on water. All are solids at room temperature. In Alkali Metals, there are lithium (Li), sodium (Na), potassium (K),rubidium (Rb), caesium (Cs), and francium (Fr).

Group 2: Alkaline earth metals

Alkaline earth metals, A group of chemical elements in the periodic table with similar properties: shiny, silvery-white, somewhat reactive at standard temperature and pressure. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Group 3: Halogens

The halogens are five non-metallic elements. Halogen means “salt-former”. The halogens are the only periodic table group containing elements in all three familiar states of matter (solid, liquid, and gas). The halogens are a group in the periodic table consisting of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

Group 4: Noble gases

Noble gases are all odorless, colorless, very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn)

At Halloween day, we got to make the Pixar story by using Halloween characters with elements. Here is one of my Pixar story about Lithium.

        Once upon a time, there was a fat ugly witch name Bablue who live in a tiny wood house in a deep jungle. Everyday Bablue always makes the poison. One day it was a big storm rainy day. Bablue can’t make her poison because the wind blows so hard and she can’t make fire. So she told her magic broom to find something that can replace fire.  After a few minutes later, her bloom came back with glass of oil with a silver rock. Then she put it in her poison. After a moment the poison was exploded and burned her hair. Because of that she turns on her computer and trying to research it. Then she saw an element name Lithium. She found out that Lithium is the chemical element with symbol Li of atomic number 3, a soft silver with the white inside like the rock that she just put into her poison at moment. It is the lightest of the alkali metals. They put them is oil because if we put them outside, it can be reacted. It’s reacted with water that why it burn her hair but if she put the just a little bit, it just boils her poison. Until finally she gets to know about it and trying to learn more about the elements.


What is alloy?

An alloy is a mixture of a metal with one or more other elements.

What is chemical bonding?

Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals and other stable species that make up the familiar substances.

What is ionic bond?

Ionic bonds is the form between metals and nonmetals.

What is Covalent bond?

Covalent bonds are bonds in which atoms share rather than transfer electrons.

What is Polar Covalent Bonds?

Polar Covalent is covalent bonds, electrons are not shared equally between the two atoms.

What is Nonpolar Covalent Bonds?

Nonpolar is covalent bonds, electrons are shared equally.


Math Round 2

This term, We are still continue working on 5A math book.  I have learn how many things about Subtract fraction, add fraction, multiply fraction, Divide fraction, geometry, Surface area and ratio.

Subtract fraction

5/6-1/12 = 3/4

To get ¾ we need to follow this steps.

There are 3 simple steps of subtract fraction:

  1. Make the denominator of the first fraction the same as the denominator to the second fraction.
  2. Subtract  the numerator ( keep the denominator).
  3. Simplify the fraction. (if needed)

Example:  5/6 – 1/12 = 10/12 – 1/12 = 9/12 = 3/4

Add fraction

2 ¾ +1 ⅛ = 3 ⅞

There are four simple steps of adding fraction:

  1. Add the whole number to the other whole number. ( Keep the whole number) Or make the mix number to the improper fraction.
  2. Make the denominator of the first fraction the same as the denominator to the second fraction
  3. Add the the numerator ( keep the denominator)
  4. Simplify the fraction. (if needed)

Note: If you make the mix number to improper fraction. You need to take the numerator divide with denominator.

Example: Mix number:2 ¾ +1 ⅛ = 3 ¾ + ⅛ = 3 6/8 + ⅛ = 3 ⅞

Improper fraction:2 ¾ = 11/4 , 1 ⅛ = 9/8

11/4 = 22/8

22/8 + 9/8 = 31/8

31/8= 3 ⅞

Multiply fraction

4/9 * 1/2 = 2/9

There are three easy steps of multiply fraction:

  1. Time the numerator to the other numerator.
  2. Time the denominator to the other numerator.
  3. Then simplify them. ( if needed)

Example: 4/9 * 1/2 = 4/18 = 2/9

Divide fraction

¾  / ½ = 3/2

There are

  1. Change the numerator of second fraction to be the denominator.
  2. Time the first numerator fraction to the other numerator.
  3. Time the denominator to the other numerator.
  4. Simplify the them. ( if needed)

Example: ¾ / ½ = ¾ *2/1 = 6/4 = 3/2


In geometry we learned how to find the area and perimeter of each shapes. Such as rectangle, square, triangle and parallelogram.


How to find the area and perimeter of rectangle

How to find the area of Triangle


How to find the  perimeter and area of square

How to find the area and perimeter of parallelogram

Surface area

In this lesson, we learning to find the surface area of a solid object and  measure of the total area that the surface of the object occupies. We only got to learn about rectangular prism and cube.

How to find the surface area of Rectangular Prisms:

How to find the surface area of cube


Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other. In Ratio, we learned how to compare the amount of something to other. We also learned how to simplify it. Ratio is my easiest lesson, it is really simple and easy to understand.

-Simplify ( if needed), Example: 12: 20= 6:10= 3:5


         One interesting thing in my class is we completed our 5A Math book within two rounds, which is last round and this round. We’re not only focus on our book but we still practice on Khan academy. This round we also practice on ( In, we are learning about algebra.


Multimedia Round 2


In this term i got to learn multimedia only three weeks but I got to to learn so many. such as:

– Learning about what make a good story

-How to write a short story by the pixar story

– Get to know about kind of photo

– How to take photo

– Illustrator

 learning about what make a good story

making a good story is writing, making a video, doing Podcast or making animation video on what are you interesting about.

Clues to write a good story:

You  can include Problem, specific sitting, emotional, not to long and good describe.

You also can include using some metaphor. Here one of my favorite example of metaphor about life:

– life is like a cloud. Today you are bright, tomorrow, you can get darker and the day after you will be disappear. The meaning is like today you are are healthy but tomorrow you can get sick or maybe the day after you can be gone.

  • problem : if your story doesn’t include problems, it’s is very simple and boring because there nothing happen.
  • specific sitting: you should tell the specific sitting because it’s make your story clear and if you writing your story and tell the specific sitting you can visualize your story.
  • emotional: emotional is very important to your story because it can effect the reader or the spectator feeling.
  • If your story is too long, the reader will be bored. So you need to describe it and take only the main idea of the story.
  • You need to describe your story clearly, like describe the specific sitting.


How to write a short story by the Pixar story

Write a short story by the pixar story, we can summarize from the movie or video to be shorter but still keep the story the same.  In Pixar story, we must need:

  • Once upon a time
  • Everyday
  • One day
  • Because of that
  • Because of that
  • Until finally
  • Note: You can use “Because of that” as much as you want.
  • Here is my example of Pixar story



Once upon a time there was women that live a big house with her lazy son name Boby. Everyday, Boby always watch TV all day long. He never go to school or help his mom to do some house work. One day, his mom met a accident and pass away. Because of that, No one clean the house or cook rice for him. His house become dirty. Because of that, He try to do some house work and cook rice by himself. He miss the food that his mom had made for him and then he try to imagine of the ingredient that have in his mom’s food. He try again and again to cook his food. Because of his determination he successfully made his own delicious food. Because of that he joined the Master Chef event. Until finally, He become a master chef.


Get to know kinds of photo

There are eight kinds of photo. Such as

  • Straight Horizon
Straight Horizon is the lines of your photo is straight.
  • Rule of third
Rule of third is the object that stay in the third row.
  • Head room
Head room is let the amount of space for the head of your photo.
  • Lead room
Lead room is let the amount of space in the photo. Like something is moving so we need to make space for those thing to go.
  • Symmetry
Symmetry is the reflection of the photos.
  • Depth
Depth is the amount of distance between the nearest and farthest objects that appear in focus.
  • Frames
Frames is the photo that have something cover surround your main focus photo.
  • Leading line
Leading Lines is all the lines in your photo should go to only one direction.

How to take photo

If you want to take a good photo, first you must know Exposure :

  • Exposure is:
  • Amount of light that reaches your camera sensor
  • Determines how light or dark your photo will be
  • What are 3 things that affect exposure?
  1. Shutter speed:
  • Length of time the shutter is open to allow light in
  • Measured in fractions of a second
  • Affects how motion is captured
(1/250 is faster), ( 1/2 is more light)


  1. Aperture
  • Size of opening in the lens through which light enters the camera
  • Measured in f-stop values
  • Affects depth of field
  • The smaller the f-stop, the more light
  • The larger the f-stop, the less light
  • Wide aperture (f/1.4) has a shallow depth of field
  • Narrow aperture (f/22) has a deep depth of field
(F2 is have more blurring back ground), (F22 have a normal background)
  1. ISO
  • How sensitive your camera is to light
  • The higher the ISO, the more sensitive the camera is to light (so photo is brighter) and it will affects image noise
  • Best to keep ISO low: only increase when aperture and shutter speed adjustments are not enough
The different of ISO.
If you put to high ISO, Your picture will have the noise. Like the right picture.
Aperture, Shutter speed and ISO.

Precious Plastic Machine

This Round 2, my exploration is about Precious Plastic Machine. In this exploration we are trying to create the machines that can recycle plastic because in our school there are so many plastic have been used. We have been research on some machines such as like shredder machine, injection machine, compression machine and extrusion machine. Our exploration we just only want to make shredder machine and injection machine.


We also went to Siam Reap to Naga Earth and Rehash Trash. We visited Naga earth to see their shredder machine and injection machine. For rehash trash we went there to know what were they doing and how they recycle plastic bags.


Naga earth

Naga earth is a really interesting organization. Naga mean Protecting so this organization is to protect Cambodia and the world. This organization,they’ve been made the wash hand soap, Bio diesel and recycle paper. They also have the shredder machine and injection machine. We also get to learn many thing from this organization.

Naga Earth’s Logo

They decide to created the Bio diesel because they want to recycle the old cooking oil. As you all know that after we used the cooking oil, we can not use it anymore but if you use it, we will have some issue because we ate the food that cook by old cooking oil. Also after we use those oil, they will go into the ground then it will go into our ocean and kill those marines life. If we take all those used cooking oil to make Bio diesel, our environment will not be harmful because Bio diesel didn’t cause to our environment.

The photo of us interviewing them how to make Bio diesel.

For making soap, it just a part of their business. Those soap are also made from oil and some more materials. After that they made those soap they also give them out to some government school in Cambodia.  

We also get to made some paper in Naga earth. Those paper are made from recycle paper and corn starch. They made paper because they want recycle paper and stop cutting down tree for making paper. There are 35% of reducing paper from cutting tree. After we making some paper, we also get to learn how to paint them with silk screen.  

The photo of they are teaching us how to make recycle paper.
Visiting Naga Earth’s Photo

Rehash Trash

Rehash trash is kind of organization and shop that recycle plastic bags into some products. We went there to see what product that we can make out of plastic and we got to learn how to make some product. There are many product that made out of plastic bags such as like basket, key chain, bags and more. The project is really protect our world because they recycle plastic bags into product.

Rehash Trash’s Logo

Rehash trash is not only make product and sell but they also help old women to have jobs to do. Some old women in Siam Reap, they are working in Rehash trash. Most of old people in Cambodia they didn’t have jobs but after rehash trash have been create they have jobs to do and get some money. It’s kind of help the poverty in Cambodia. Rehash trash is a great organization because it’s helping environment and people in poverty.

We are Learning how to make Key chains and Bracelets from Plastic Bags.


How it impact me?

How you impact your country?


This two trips were impact me a lot of things. When I went to Naga earth one thing that it was impact me is recycle paper. Making bio fuel and washing hand soap, it’s kind of hard because we need some machines to make them. Recycle paper is easy because we didn’t need machines. We just need used paper, cornstarch, water and some of the materials. It was impact me to teach my friends and my community to recycle paper. I want to teach them how recycle paper because it’s apart of reduce paper from cutting down tree.

After went to rehash trash I know how to make some of the products.  It was impact me to teach my friends to know how to make products from plastic bags and reduce using plastic bags. I want to teach them because plastic is everywhere. Rehash trash is a small shop but if I teach my friends and my friends teach other people, we will reduce some plastic bags from going to the landfill.


After we went back to our school, we also think about the idea of teaching our friends to make paper and some products from plastic bags. Our exploration group will be the facilitators who teach them to make paper and plastic products. We start to teach them on Wednesday which is in creative arts class.

I really love this exploration because we are trying to eliminate plastic from our planet. We are trying to research and finding some products and machines that can recycle plastic. We went on trip to see what were some of the ideas that we can help our environment. After that, we found out that we can reuse plastic bags to make some products. Not only that we also found out how to recycle paper to reduce cutting down tree. I think this project is really help our country to be more developed. As I am a change agent, I need to know how can I stop using the weapon to destroy my country and my planet.



In this term, I have so many thing in this class, especially new words. In this class in one week, we learn ten new words. Also we have homework packet to do every weeks and different root words. We also read some articles especially from Newsela and Readwork. For the first week, I were learned about The gods behind the days of the week

According to some information about Newsela, they said that there are seven days of the week and all those day, it was name from all the planets in the solar system. These names started with the Romans, who ruled over much of Europe about 2,000 years ago. The Romans spoke a language called Latin. Such as like :


  • Sunday was “dies Solis,” the day of the sun.


  • Monday was “dies Lunae,” the day of the moon.
  • Tuesday was “dies Martis,” the day of Mars.
  • Wednesday was “dies Mercurii,” the day of Mercury.
  • Thursday was “dies Iovis,” the day of Jupiter.
  • Friday was “dies Veneris,” the day of Venus.
  • Saturday was “dies Saturni,” the day of Saturn.

How those days were named by :

There One of these groups, the Anglo-Saxons, brought their gods and language to what is now Great Britain. In English, Saturday was named after Saturn, Sunday after the sun and Monday after the moon. The other four days, Tuesday, Wednesday, Thursday and Friday, were named after Anglo-Saxon gods.

  • Tuesday is named after the god Tiw. This god was probably a god of war, just like the Roman god Mars.
  • Wednesday is named after the god Woden, who is like the Roman god Mercury.
  • Thursday is Thor’s day, or the day of thunder. It is related to the Latin “dies Iovis,” or the day of Jupiter.
  • Friday is the only weekday named after a female god, Frig.

It was kind of surprise for me, because in Cambodia the name of all the days were taking from all the planets too.


In this class, we are not only learn from our teacher but we also read some articles from Newsela and Readwork.  


Newsela is a website that we can read some news or articles. Newsela is a great website for me because it has a lot of articles. After we read all those articles, we also can get some more information. There are so many category in this website. There have some block in this website such as Library, news, text set, collection and we also can research  some articles that we want to read about. If you click on Library there are so many information for you to read. If you try it, there will have more interesting thing for you . After we read those articles, we also can take quiz to know how much that we can understand about that articles. Our facilitator can also assign some works for us to do.



Readwork also the great website that can help us with our learning. In this website, we also can read some articles. This website is similar to Newsela but I think Newsela is a global website because everyone can get to read the articles. For Readwork, we can read only when our facilitator assign us to read . It’s also kind of easy because it has some vocabularies of some difficult words for us when we don’t understand. It also has some quiz for us.


I really love these two websites.


After we finish some of our work in class, we also independent reading. Our class is at led studio center, which the place that we store our books in there so it’s really easy for us to choose the books to read. We also have literacy on Wednesday. After we finish those books. We were doing inspire piece of art. I were a book, which is The humming room and I were writing a poem about it. Here is my poem:

The Humming Room

Roo is a little brave girl

She live in the world that no one care

She also look like a little bear

No one was care when her parents pass away


After a while her aunt took her to live in a house

It seem only the mouses that live in there

When She went in, she just look and stair

See what in there why it was so quiet


First time living in there was so mystery

And it was not free like living alone

But her heart was like a stone

Cause she had grown by herself


That house was really scary

So Roo wanted to see were happened

So she went into the room had been abandoned

It was like a heaven when she  go in


When she went in seeing a boy

And all those voice were come from him

Every night he always scream, cause all his dream, it had been gone


He dreamed to see his mommy

But suddenly his mom had pass

It seem like him losing a brush

And all the dust come in his life


Knowing all the problem that he has

She start to clean all the mess

Growing the plants that have been dead

From thing were flat to be thicker


His mom had left a dead garden

But Roo comment to grow it back

Make all those plant to become shake

It can also make, him to remember


After a few month the garden turn green

And all the wind brush dust a way

That what he want and had been pray

And his new day were starting now


That cause some help from little girl

She like a pearl shine for a person

She help a boy with no reason

What she has done is her kindness


She teaching me to be more brave

She also drive me to kindness

Even the start it was a mess

But she try her best helping other.


Brave is the shield of fearness

Kindness is the weapon that kill selfish


No Plastic

In Liger Leadership Academy, we also have some explorations. Exploration is a seven weeks project. My first exploration for this year in No plastic in Liger. This exploration is really important for our school, not only for our school but also important for our environment. This exploration was created by one of our facilitators. It was created because there are so many plastics have been used in Liger. This exploration of stops using plastic. In this seven weeks, we’ve been collecting all the trash around our school and do a survey how many plastics get in Liger in one day. Now we are trying to eliminate plastic straws, Styrofoam, and cups. We also find some product that can replace plastics. The product, that we found for replace plastics are mental boxes, metal straw, stainless steel water bottles or cups. We also went on a trip to get some more information about other products. There are two places that we have been visited and interview.

The first place that we’ve been to is Better U.
Better is a cafe that located in AEON mall 2. This cafe a great place from other cafes because they use grass straw instead of plastic straw. We got to interview them about the grass straw. This grass straws made in Cambodia and it does not affect the environment. They started to use grass straw because they help to save our environment.

We went to the cafe “better U” that selling grass straw.

For only one planet, this company is selling some biodegradable product. That company is really good. They are not only selling the biodegradable product but they also sell the stainless steel product such as water bottles, cup, and mental straw.

Only One Planet’s Logo

After interviewing them, we also bought some products such as bags and mental straws for some of our students. Then we interview our students for those of who got the product. After they use those products. Most of them, they said those products were really good. After getting all those data, we bought more product for all our students and staffs.
After this seven weeks, we have a Sharation about our project. We get to share our exploration’s idea for people that come to join our Sharation, for them to know how plastics affect our environment. We do that because we want to spread our idea to all people in Cambodia because some people they come from outside Liger.
We also create a Pixar pitch for our Sharation.
Once upon a time, a new product was invented to help makes people life easier and it was single-use plastic.
Every day, people started to use it and it became well known all around the world that makes packaging and packing a lot easier.
One day, researchers and scientists found out about how the plastic can pollute the environment, our planet and mainly it, affect us, humans. They had tried to persuade people to think about the problems but unfortunately, they still use plastic because it’s easy to use and convenience for them.
Because of that, The long terms plastic problems started to spread all over the world affecting Cambodia along the way.
Because of that, an exploration was created by a group of Liger’s students to solve the single-use plastic problems in Liger community.
Until Finally, they launch a campaign, giving out stainless steel straws and nylon bags to everyone in the Liger family to reduce the single-use plastic.

I really love this exploration because it saving our environment. As you all know plastic is really bad for our environment. If we stop using it, it gonna be great for our environment. Using plastic is like using poison to kill yourself. Nowadays there are so many plastics in Cambodia. That plastic ended up in the ocean. All the marine life were living in the trash ocean. Even it affects marine life but one day it also affects our life. Our future plan, we are not trying to eliminate in Liger but we also want all Cambodia people to stop using plastics and we want Liger students the one who change agent. The one who stops the idea of using plastic in Cambodia is Liger.
“Some people just only think what easy for them, but they don’t even think about the environment and other”

We are using Paper box instead of using plastic bag.


In  2018 this term, I just start to learn about multimedia. In class we have been learning about how to research,Photoshop, Light-room, adobe In-design and Algorithm. We get to learn just a little bit because this class, we have divided with STEM class.

As we all know, Photoshop is an application that we can edit the photo, cut, or add other photo to be in that photo. For light-room is an application that we can edit the light to be dark or bright. In-design is an application that we can make books.

This is the picture that I have been edit in Photoshop and Light-room

This some of information that I have been research about Hillier and put all those information in the adobe In-design.

This some of information that I have been research about Hillier and put all those information in the adobe In-design.



Algorithm is a process or set of rules to be followed in calculations or other problem-solving operations. When I learn this, it is really helpful and it can make me to calculate the result faster. The algorithm especially code by a computer so we need to learn about pseudo code too.

Here are some of the pseudo code that I just learned:

The rule of it n (n+1)/2

  • Input: “read ( number)”
  • Output: “print ( number)”
  • Math operation: +, -, *, /
  • Variables: Y= ( number)


I really love this class because it really help me a lot about editing photo, how to research and algorithm. In the future is this class we will learn about computer science and how to code.




In Liger Leadership academy, we also have STEM class. This class is my most favorite class because I love science. The meaning of STEM are:

S : Science

T : Technology

E : Engineering

M : Math

Mostly this class were study about science. I have been learn this subject for two years. In this term, I have learned about physical science . This class mainly, we were learn from a website, that called CK-12 . We were started from learning about Mass and Atoms.

Here are some lesson that I have been learn for this term about Mass:

  • Matter were made of mass and volume
  • The unit of weight and newton
  • Chemical poverty
  • Physical poverty
  • Mass and weight

The difference between Mass and weight:

  • The unit of Newton and Kilogram:
  • Newton is weight
  • Kilogram is mass
  • How to find is take the Kilogram time with 9.8 equal Newton

What I have learned about Atom:

  • How Atom made out of
  • Proton
  • Neutron
  • Electron
  • Neutral
  • Ion
  • Quark
  • Atomic number
  • Atomic mass

Here are some examples:

  • Types of Quark

  • Atom

We are not just learn from the teacher or some websites but we also do some experiment about it. Doing experiment is really helpful for me to understand about my lesson because we are not just take notes and listen to the teacher but we take action to know more about it. Also after we finish doing experiment or research, we were share the information about our lesson to explain more about some part that we not really get to know to our classmate.
