Stem round 1

This is our four year we started to go deeper and deeper in our stem class we are studying about animal cell and plant cell. I never know anything about it before but after I learn it for 2 week I started to understand more about it. Let me tell you what I have understood so far about animal cell and plant cells. What is the difference between an animal cell and a plant cell?  A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall. There are so many organelles in animal cell and plant cell. The most important orgallen in an animal cell is nucleus, cytoplasm, ER, Golgi body, lysosome, nucleolus, mitochondria, cell membrane and for the most important for plant cell is Chromoplasts, Chromoplasts, Leucoplasts. The nucleus is the main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The cytoplasm is watery that helps the organelle flow around and also it helps the cell to keep in shape. ER is something that lets the nucleus stick to it and then the vesicle going to take the protein to the Golgi body. The Golgi body is a place that helps to change the shape of a protein and it also can add on something to a protein like a carbohydrate and a lipid. The lysosome is like a trash bin that it trying to collect all the trash in the cell and break it down with enzymes.midrochondria is a place that it create energy for every organelle to work well and the energy that it produces is  ATP. The last is cell membrane, cell membrane it can let other elements get into the cell or get out from the cell.

 

So for Chromoplasts are plastids that contain chlorophyll. Chlorophyll is a green pigment. It gives plants their green color. Photosynthesis takes place in chloroplasts. They capture sunlight and use its energy to make glucose. Chromoplasts are plastids that contain other pigments. These other pigments give flowers and fruits their colors. Leucoplasts are plastids that make or store other molecules. For example, some leucoplasts make amino acids. Other leucoplasts store starch or oil.

Electricity exploration round 1

For me, I think this is a really cool exploration. This exploration call Electricity in Cambodia. In this exploration we wanted to know more a lot about electricity in Cambodia and document it on our website, and also we need to know where does the electricity comes from. First, I think electricity came from outside countries like Vietnam and Thailand. But After I learn in this exploration I know a lot about it. Let me tell you what we have learned so far in this exploration. We have divided each other into 4 groups and all of them have work to do, they need to research on any energy source like hydropower, solar, windmill, else

 

So my team are working on how hydropower work? Let me tell you a bit of information that I know from how it work.

 

Hydropower create the energy of falling water through the dam. The hydro dam can be constructed anywhere that has a flowing stream of water. There​ are four main part in hydropower: 

 

Dams are built to store and raise the level of water such as rivers to create flowing water. They can control the flow of water and effectively store the water used to provide energy at any time. 

 

Turbine is a rotary mechanical device that is one of the main components to produce energy. They spin from the motion of falling water and turn it into mechanical energy. 

 

Generator is connected to the turbine. When the turbine spin the generator acts the same. It converts mechanical energy from the turbine into electrical energy.

 

 Transmission lines so after generator create electricity the Transmission lines can make the electricity increase or decrease.

 

I also know a lot about the generator, so the generator has the magnet around the copper wire. It will create electricity when the copper wire spin around the magnet but if you imagine the generator that we use to create an electricity every day is really really big and we can’t use our force to spin it, so how can we spin that generator. We need to use something to call a Turbine, the turbine are connected to generator so when the Turbine spin the generator is also spin like a turbine too.

 

There are 7 dams that operating in cambodia

 

  • Kirirom I (12MW) in Kampong Speu
  • Kamchay (193MW) in Kampot, which started operating in 2011
  • Kirirom III (18MW), which started operating in 2013
  • Stung Atai (120MW) in Pursat, which started operating in 2013
  • Lower Russei Chrum (338MW) in Koh Kong, which started operating in 2014
  • Stung Tatai (246MW) in Koh Kong, which began power production in 2014
  • Lower Sesan II (400MW) in Stung Treng province, officially opened in 2018.

All of those 7 Dam mostly the owner is china and just only 2 of them are Cambodia, in one year all of that dam can create about 1327 MW every year but that 1327 MW can’t go to all the people in Cambodia so some people who live off-grid some they need to use a solar panel or wind power. EDC goal is to make all the people in Cambodia be on the grid by 2023.

How I change Cambodia (2018-2019)

How I change Cambodia

 

There are about 10 million plastic bags are being used in Phnom Penh, so what about if we think of the hold country, It a lot. From what I have learned is plastic is really useful for our daily life. Example if I ask 100 people in Cambodia I believe that nearly all of them said that plastic is useful for them. 

 

Did you think about the effect? It really affects our planet events to humans too. Independent.co said that It really effects to our marine life because for Example: if you throw a plastic bags into an ocean fish or some animal gonna come and eat it and it’s gonna cost a really big problem. 

 

My team is learning how to stop people to not using the plastic bag but it does not really work so then we come up with an idea to go to different provinces to present to a village and also to a village chief. After 1 month later I hear that province is a less plastic bag, we were really happy to hear that! Let me tell you what we have presented to the villagers, we didn’t tell them to stop using plastic but we tell them to recycle plastic because ask you know most of the villager, in one day they use lots of plastic bags so we tell them to recycle plastic for example if today they got 2 plastic bags the next day they gonna use that plastic bag again, they can change the plastic bag every 3 or 4 days so that it’s gonna less plastic in the village. We also made a video to encourage people to know more about the plastic bag. 

 

Another exploration we did to change Cambodia is engineering because as you know in Cambodia there a problem that the kid in Cambodia in some provinces they didn’t really know about engineering. We create this exploration because we want to encourage the kids in Cambodia to learn about this stem project.

 

 In this exploration we have divided the students into 3 groups to do a different project after 3 weeks we went to a school to tell the student about what we are doing and most of them are really confused on our project but after 1 hour later. They understand what we are doing and they look so passionate on the project that we tell them to do. The end of our project we call 5 to 6 students to tell us what is passionate about what they are doing today and how they feel and we also got a really great reply from them. That is it for this exploration, so let’s go to another exploration that can help to change Cambodia.

 

 In this exploration is mostly about nature, It is Ecotourism. We have two round for this exploration, I join this exploration in round two and I didn’t understand anything about Ecotourism. Ecotourism is a form of tourism involving visiting fragile, pristine, and relatively undisturbed natural areas, intended as a low-impact and often small scale alternative to standard commercial mass tourism (A connection with nature and community).

 

 After 2 weeks later we have been to chombok that located in Kampong speu province. We have been there to see the example of an Ecotourism there. 4 week later we have been to Preah Vihear province choam pen community. On the first day that we were there, we ride a hand tractor to get into a forest. We learn so many things from our guide and one more what we have seen so far is we can create an Ecotourism there. To do this our team working really hard together to make this Ecotourism we have met with different people in the community especially with a district garment in that community. Most of the people in the community they really surprise with our project and they want this project to have. But we didn’t promise to them yet, We don’t if this project going to work or not but if it works the community going to be developed. From what I have said that I also want this exploration to get up so I’m going to try my best because most of the people in the community they really want this exploration to be work. That is it I don’t have anything to talk but I believe that these three projects going to help to change Cambodia in one day.

This is the fourth round of math class. We getting deeper and deeper into a hard lesson but it help us a lots while we are taking test now we are started to use 5B book and we are working on angle and learn a lots of rules of angle. At the start of angle we need to know some angle first like complementary angle, vertically opposite, supplementary angle, If you know all of that angle it gonna be so easy for you to learn angles. Now in the class we be more quiet because we doesn’t want to distract other people while they are learning we also have to do homework every week too. It hard but we have time to do it.

Multimidia round 4

Now round fourth is coming. It gets harder and harder but we also need to try hard too. Ask you know the last term we are learning about python. This term we also learn about python but a different category of python, It is Python Dictionaries this is one of my favorite python categories because of it easy to understand and it not really hard because we have an app call Trinket to help us with Python Dictionaries code. The app helps us to write code, it gives us an instruction to code. Here are an example:  (https://trinket.io/python/3297d81ef9) To do this teacher need to know clearly about the app to explain to the student. For the app is free you can start to write your code if you click here: (https://codeclubprojects.org/en-GB/python/team-chooser/)

Math round 3

 

 

This is the third year so the level started to get high. Now we have our new book is primary mathematics (5B). The lesson that we start is call decimals, we learn how to divide decimals, and rounding decimals,divide whole number at the end of lesson we going to have a small quiz. I hope that each student gonna have a good score on there quiz. We also have fun with our classmate and our teacher. Teacher always give us a fun activity nearly every, for HW it is not really hard we have one week to finish our HW and we have a lot of fun.
