In math class round 3, we have continued to the new level of book which is 5B. In this round we’ve learned two chapter one is about decimal and other on is about measure and volume. For decimals we learned about the places of each decimals, converting from decimal to fraction and some word problems. We also learned about binary numbers as well because it related to decimal. For measure and volume, we had learned about some measurement and we also learn how to calculate each every solid shape to find the volume of it. We also did some word problems. Moreover, we still follow to learn to improves some more learning which we work as team, be able to ask questions confidently, respect each other in class etc…. I think for this round we work as a team a lot and I think I’ve improve on learning a lot meaning that word problem is not really struggle me like before. I hope to learn some more interesting things more in the next round.
Indigenous Community exploration is a seven weeks project to research and learn about some indigenous groups in Cambodia. For this round we only focus on two indigenous group which are Kui ( Preah Vihear) and Steing ( Kratie). There are 9 theme to focus on and learn about. They are ceremony, food, geography, norm/belief, education/ healthcare, economy/daily life, language, music/art and people/ environment. The goals of this exploration help to promote and preserve indigenous groups. Throughout this exploration we also want to improve our interview skills, writing skills, photography skills, designing skill and video skills. At the end of this exploration we publish a book of Kui community and video of Steing community.
In order to achieve this we also went on trip to those two provinces which are Preah Vihear and Kratie to interview those indigenous group to get the information to put in our book and video. After the trips, we gather all the information and put it in the book and video. Each students have their own responsibility to responsible for own research theme. After we gather the information and out in the book and check with our facilitator , we also went back to the community to verify the information with the community people.
Overall, I have learned a lot from this exploration, not just skills but also how we can work as team, problem solver and how to adapt to situation which sometime we don’t have bathroom to take shower and we have only well so we have to adapt to that kind of situation. That’s just one situation that we facing but there are more problem that need to solve. Also, I have impacted a lot to this country by help to promote indigenous group. I hope to help the country more.

Carbon is one of the main topic that we focus on in STEM class for this round. Carbon is a nonmetal element. Carbon has four valence electron. So, it need four more electron in order to complete its outer energy level. In order to achieve this it need covalent bond that is form between nonmetal which they share a pair of electron. Usually, carbon form bond with hydrogen. There are three types of bond of carbon with other carbon atoms. Those bond are single, double and triple bond. Single bond is when they share a pair of electron. Double bond is when they share two pairs of bond and triple bond is when they share three pairs of bond. The types of single bond are called Alkane. The type of double bond are called Alkene and the type of triple bond are called Alkyne.
We also learned about hydrocarbon. Hydrocarbon are compounds that contain only carbon and hydrogen. There are two types of hydrocarbon which are saturated hydrocarbon and unsaturated hydrocarbon. Saturated hydrocarbon contain only single bond which is alkane type. The name of alkane is always end with “ane”.The first part of the name indicates how many carbon atom each has. The smallest is called Methane which has only one carbon atom. The next are Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Nonane and Decane.
This are the list with molecular formula
Unsaturated carbon can be double or triple bond which are Alkene or Alkyne. The type of Alkene is always end with “ene”. The type of Alkyne is always end with “yne”. It’s also indicates to how many carbon atom each has.
Overall, I feel it been a great round for me. I think I has understand a lot more about STEM. Also, I feel more confidence in asking question and has increase my passion in STEM. I hope to see more challenge and fun in the next round.
The theme for this round is “Identity”. Some guiding question to ask yourself are, “Who are you?”, “What make who you are?”, “What are some factor that help to define you?”. I’ve wrote a description of my name. Throughout this round we did so many such as writing poem, writing about the meaning of our name. Also this past few weeks we did read a novel book. Our facilitator has four book for us to choose. They are Wonder, Looking for Alaska, Monster and Outsider. I decide to choose to read about Looking For Alaska book. This book i a little bit more mature, however we still get through it. Furthermore, we also a discussion every week with the team. In a team we have different role to share from the story which are, Summarizer, Visualizer, Inferencer, Symbolizer and Word Detectives. I think this round is great round because it had taught me a lot and I got to know more about my Identity. Furthermore, it help to me to build more of passion on reading as I was a person that doesn’t like to read.
This is “Where I am From?” Poem and The meaning of my name “Leza”
For this round, we are going a little deeper into a programming language called Python. We have learned a lot of different data type such as booleans, comparison, if statement, elif statement, else statement etc…. Python programming language also has its own grammar which means we need to write it correctly that it could understand. Indentation is one of the most common mistakes that people always make an error in python. Boolean is a data type that can have the values true or false. Comparison is a data type that use to compare the value of the number or variable. if , elif or else are a data type that use to check if the statement is true or not. We also learn about And Or and Not. It is a word to connect the statement together. And is used to check if both states are true. Or is used to check if one of the statement is true. Not is used to flip the value of the statement.
Some more important that we just learn are about for loops and while loops. For “for loop” when you want to perform some action a fix number of times. For “ while loops” is to perform the action until the condition. Throughout using that loops we can use break statement to stop the code and we can use continue statement to skip the repetition of the code.

In STEM class I’ve learned a lot, but for this round, we mainly focus on periodic table and chemical bond. We still use the same website which is CK-12.
The first person who creates a periodic table is Mendeleev. There are 118 elements in the periodic table. At that time Mendeleev has arranged the elements by its atomic mass. Atomic mass is the mass of protons and neutrons in the atom. For nowadays people use a modern periodic table which they have arranged the elements by its atomic number. Atomic number is the number of protons in an atom of an element. There also a chemical symbol to represent the element which consists of one or two letter that comes from the chemical’s name in English or other languages. For example, the symbol of lead is Pb which come from a Latin word plumbum.
They also divide the elements into three types which are metals( blue), metalloids or semimetals (orange), and nonmetals (green). The rows on the periodic table called period and the columns of the periodic table are called groups. Some period of the modern periodic table are longer than others you can see the first have only two elements and the period 6 and 7 its contrast so long that some of their elements are placed below the main part of the table. As you can see most of the element are metals. Metals are the elements that are good at conductor of electricity and a relatively high melting point. So, almost all at the room temperature. They are the largest of the classed in the modern periodic table. Most of the metal are also good conductors of heats. Nonmetal are the elements that do not conduct electricity, poor conductors of heat and it is the second largest classes of the elements. Nonmetals generally have properties that are opposite of those metals. Metalloids is the element that in between metals and nonmetals. Metalloid has some properties of metals and some properties of nonmetals. For example, many metalloids can conduct electricity but only at a certain temperature and these metalloids are called semiconductors.
There also some groups of the element which are Alkali metal, Alkaline Earth Metal, Halogen and Noble gas. Alkali Metal has just only one valence electrons which are highly reactive. Alkali Metal is the most reactive of all the metals. Most of Alkali Metal is soft which enough to cut with knife. Alkali metal has also low density. Alkaline Earth Metal is the elements that is in group two. They have two valence electrons. They also very reactive but not like alkali metals. They are harder and denser than the alkali metal. Groups 3-12 are called Transition Metals. Transition have more valence electron and less reactive than metal and the first two groups metals. They are shiny, very hard, high melting points and boiling points. Halogens are all the elements that in the group 17. They are highly reactive nonmetal and with 7 valence electrons. Halogen group include gas, liquid and solid and they react violently with alkali metals. The last group is Noble gas. The nonmetal elements that in groups 18 are called Noble gas group. They are the least reactive group because their outer energy level is full and they are colorless odorless gases.
In literacy class, there will be a different theme for each round. For this round, the theme was about “ Social and Environmental Injustice”. Basically, the environmental injustice is related to the unfair treatment of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. Throughout the lesson, we have done a lot of exercises such as complete the hyperdoc about the minority group map and philosophical chair which is when the statement was given and we need to decide on agree or disagree. Then we will start to debate on that topic respectfully. One more thing that is the bigger accomplishment is every student had written their own argumentive essay. Throughout that writing, I also learned about how to choose a great topic, how to write a thesis statement and how to cite the evidence and source. I think it’s a great round which all the students get to practice their own writing skills.
In math class this round, I’ve learned two things which geometry and ratio but one thing I like the most is the ratio. The ratio is the way to use math to compare things. I’ve learned how to compare things like for example, 5 blue pens to 10 red pens so we gonna write it like 5:10. Not just only that but we also learn how to simplify it which we called Equivalent ratio for example 5:10 = 1:2. We have done a lot of practice throughout this lesson like budgeting, recipe and the number of students and staff in liger. For geometry, we have learned so many such areas, perimeter. We also learn about different polygons such as a triangle, square, rectangle and parallelogram. Throughout the lesson, we also practice solving word problems related to ratios or geometry. I think word problems are very tricky to me but I hope I can get better at it in the next round. One more thing is that our facilitator has also introduced us to algebra on code.org. This algebra exercise is like extra practice. Overall, I think this round is very interesting. It will be more exciting in the next round which is 5B.
