Geometry and Ratio

      Geometry is an important lesson in math and it can be used for engineering, architecture, graphic design…. In the class, I learn about finding the area and the perimeter of the triangle, square, rectangle, and parallelogram. Through the lesson, I face a lot of challenge because there are many shapes and formulas and especially the triangle. However, my math teacher had given everyone a website call khanacademy( to work on. It a website where the teacher can put any assignment about any subject for us to do. Moreover, If you don’t understand it you can go to watch some videos where they explain to you about the topic.

      Ratio is using math to compare things. For example, if you wanted to compare the number of Female and male in the world you also can use the ratio to do it. In ratio, we use “:” to represent the word “to” like“ 3:4 ” you call it “three to four”.Even though the number is big, you can simplify it in a smaller fraction. Example, if you a have “12:24” you can simplify it in to “1:2” so it makes us easier to compare it.

       After all, I learn a lot of things that can apply it to my everyday life or to the future. if I am an engineering in the future, I can use geometry to help me with it.


           In round 2, for Technology and Multimedia class we learn about the camera. First, we learn what is exposure. Exposure is the amount of light that reaches into your camera and it determined how dark or bright your photo look. There are three things that can affect exposure such as shutter speed, aperture, and ISO.

           Shutter speed is the amount of time that the shutter in the camera open to allow the light to go in.  If the shutter speed is doubled, the doubles amount of light come in. The higher the number is, the brighter and bluer the photo will be. For example, 2s(second) is slower than 1/100 so the photo will be blur and it will make your photo brighter.

           Aperture is how large or small the side of the lens in the camera is, which allows the light to come through. The larger the number is, the smaller the lens open. The aperture affects the depth of field. It means if you make the number higher, the background will be clear but if the number is low the background will be blur. It also affects the light for example, if the lens is small the less light will come in.

( high number )  ( low number )

           ISO is how sensitive your camera is to light. There are levels with numbers of ISO on your camera such as 100, 200, 400, 600, 800, 1000 etc. The higher the number is, the more sensitive your camera is to light so your photo will be brighter than how it looks in real life. If your ISO is too high it also will make the photo has noises( like the one above ). So it is good to keep your ISO low, but if you want to make your photo brighter your first step is to change the shutter speed and the aperture.

           Overall, I learn a lot of things about the camera and I can apply it my every life by taking pictures.  In the future, I hope that I can apply it bigger than this.

Tos Merl Theater

           In the first term of this year, my exploration is call community traveling theater. It runs by Sushi Firas, he is an art teacher in liger. In the exploration, we are working on a project that is about making a theater on a truck so it can travel around and show plays, movies to the villager around Cambodia. During the project, we also change the name “ community traveling theater ” to a new name call “ Tos merl liger community traveling theater ” Tos merl is a word in Khmer mean “let’s watch”. We do make a logo of the project too.

            To do the theater we need a truck like I said above, and we have to spend the money on it but we don’t have any. So my group decides to do some crowdfunding to let people donate us some money. In the crowdfunding, we want to put a video about what will the theater make the people feel after they had watched the play. So to do that we had a trip to Tbong Khmum and Kampong Cham province to interview and to show the play to the villager there.

             This exploration will not end like this so I think that the next term there will be the second round on this exploration only If we have the money from the crowdfunding.


What is root words?

What is root words?

In the Literacy class, we do a lot of especially writing and reading. In this term we learn about the history of the language through time, how has it change, and a lot of root words.

Example of a root word is “Hydr” it means water. Most of the words that have “hydr” in it usually related to water like, hydrate, hydroelectric, hydrant and more. Some root words also have the same meaning like “hydr” and “aqua/aqu” mean water.

Here are some root words that I learn

Hydr – water

Aqua/Aqu – water

Mar/Mer – sea

Bio – life

Photo – light

Phil – love

Vis/Vid -see,look

Aud – hear

Phon – sound.



In the first round of Technology/Multimedia the first week we learn about the research skill. First Cindy( the class’s facilitator ) let us choose a topic and write some questions to research about. I chose the statue of liberty to research on because I want to know more about it. After answer some question I have to find a primary source and a secondary source to prove my answer.

For week two we learn about how to use some Adobe to write the information that we search on last week and edit some pictures that related to our topic. We use Adobe Indesign, Photoshop, and classic cc. A lot of us doesn’t know how to use these but some do, so the people that they know how to use these they teach everyone how to use it. First I don’t know anything about it at all but by the end of the week I can use is well. For week three Cindy Just introduce us a bit about coding because most of us don’t know how to code yet and it is hard to understand so it gonna take some time. Overall I really enjoy this class because I learn a lot of thing within three weeks.


Math is very important for me and it also very useful for everyone. Math can be used in science, economic, technology, chemistry and more classes. In the past few week in my math class, I learn a lot about fraction and word problems. I learn about how to plus, subtract, multiply, and divide fraction and fraction.

For me fraction is not too complicated but for word problem that have to do with fraction in it is a little complicated because sometime it is a bit tricky and I have to draw some picture for me to understand it more. Just so you know I am a visual learner so almost all of the this I do I usually draw pictures.
