It is a very unique exploration. We research about it, we share it, we do it and we achieve it. In the first to third week or so, we studied about different types of engineering. I really like medical engineering, because i love saving people’s life. After this lesson, we learn about 6 different types of simple machine. I don’t know about all these before i learn this. Well, i know few, but not all. All of them are really important for my works in life. I just realized that, everything that we use to help our works, require those simple machine! Next lesson is, designing process. It does not mean that, we can only use it use it for engineering, but everything needs that. Even writing, creating a products and more. On the other hand, this is not it. Our exploration goal is to get Cambodian kids in public school engage in stem projects. We find a projects that we want to make, and then do it as a Cambodian friendly. Which means, all the material must be easy to find in Cambodia. After we know exactly what we are going to do, we go out into different schools and then teach them how to do our project. We also get some feedback from them, so we could make changes to our instruct-able. My team create a slingshot car, because it is a toy so, the kids will be interested in it. We really want to kid to engage in some creative activity, so we decide to challenge them to, design their car by them self. They really enjoy the projects, and i’m so glad that they all show their ingenuity for the cars and appreciation towards us that we go and teach them something new. For me, I really want to do this project again, because it really help the kids to relax and give them some more fun time as well as improving their creativity. They can even use this car to compete each other, like a race in their free time. So, the best part is, it is easy to make, and easy to play. If you want to see our instruct able, you can see it under my text. I wrote it both in Khmer and English so, Cambodian can see it and follow it easily.

How to be happy after a lose

happiness are everywhere. “Don’t cry because it’s over, smile because it happened.”
― Dr. Seuss

Sometimes, the happiness that you have suddenly fades away. Maybe you lost your job, someone you love or a competition. None of us here would want any of those to affect our day. However, one moment in life there will be some unexpected events happen at some point. On the other hand, don’t worry too much on this, you have come to the right place.  You will just need your eyes, ears and your heart. There are more than three ways to be able to be happy. Those can be, accepting the loss, your favorite subjects, nature, and lose today does not mean you’ll lose tomorrow.

Accepting the loss. I know it is not easy for you, but hold on! You should learn. According to Kathryn Sandford from life, she stated that “ healing is a process”. Which also mean, anything that occur can be healed by time. When you lose something, it does not mean you are frail. It was just fate. After this experience, I’m sure you’ll get some advantages like, be strong and brave. Aisha Chaudhary, have a really bad condition for her health, but she won’t give up and she won’t let those fears ruin what she wanted to do. Even though you know that you will lose it, you should be happy and do anything you could do with it. Just before it’s gone forever. The great depression, that happened years ago in the United State, is one of the best example. Netizens lose all things. However, they have determination, and fight over those fears, until they got back into a great empire as nowadays. well, correct me if i’m wrong

Another ways is that, you could find your favorite things to do. It is very simple, because I’m sure that you know what you like. Enjoy the tiny beat that left over. Music is one of the common activity that people love. On the other hand, you can also draw and write about your feeling. Sometimes, you might not want to talk about those sadness in front of people, so drawing and writing is the best way to express your emotion quietly. However, if you don’t like writing, you can just talk to someone you trust. Even though those talks might give you some memory, but you have to find one silver line inside of it. It’s like picking a perfect peach to eat for summer. After raining, there must be sunshine that will dry your wetness. My close friend has lost her little sister that was just born. It’s sad and touched to everyone. However, she said “crying can’t help my sister to be alive again, remembering those who always near me is enough”.  Isn’t it true? When we loss someone in life, it does not mean that type of thing is gone forever. There must be someone or something new that can be replace that object. Look around and accept the other good feeling that others had given to you. You’ll be happy after.

Another great way to be happy, is going into nature. There are plenty of precious creatures that are unexpected to be seen. There is one unique way that nature can make us feel very happy. Following a website called yes, they stated” exposure of nature may also have physical and mental health benefit”. It means, the exposure that shows us in nature, gives us very positive impacts, no matter where, when and who. In the 1770-1850 there is a poem wrote by a English romance poet called “wander as a lonely”. it gives the emotion that he got from nature. If you don’t know what to do, just wander around and you will see a beautiful scene at some moment. Isn’t it great to go with a vacant hand, and come back with a sprightly brain?  Use your six senses correctly. Listen to the sound of wind and animal that create a beautiful song. Use your eyes to ensue what’s around and spot what is different. I bet you will see something interesting from nature. It is very jocund to do so.

Losing today does not mean you will lose tomorrow. Don’t worry, be happy.My dad always told me that, use my failure as a guide. Don’t be upset for those mistakes. Take it, and compare. What are your weakness?. After you find those, try to avoid that action in the next event. That’s what my dad said. Maanvi Singh wrote a article called ““you can buy happiness, if it’s an experience” ” she is inspiring people & me to take failure as an experience. After so many experience, I guarantee you that, you will get succeed in one day. On the other hand, don’t use your money to buy happiness.

At the end of the day, you will have to follow one of these steps to be happy. Happiness is the choice. You can find it right under your nose. Let’s not allow those problems that happened, infects your beautiful day. Happiness are free, so take it ask much as you can. If you no one give you, I’ll do!

You did great, and no one is greater than you” – Raksa

.“ Do what you love, accept who you are and save what you have” – Aisha chaudhary

“enjoy life, there are plenty of time for death” – Aisha chaudhary

P.s *Even though you want to use your money to buy those happiness, it does not mean anything. Why? Because, it does not comes from your own effort and your true self. Money can’t buy happiness. Example, when you are sad, you can not go to someone that is happy and buy 5$ of their happiness. Do you think it is possible to do that?

Phython round 4

my coding project using trinket.

Before we learn this lesson,  i thought we are going to use code blog. however, we are actually, writing our own codes! it is very hard to understand every of the variable and how it is works. there are a lot of function and words that i don’t understand. on the other hand, i always miss class twice a week, which make my life even harder. I need to ask my friend about the lesson that we’ve learned in class and try my best to understand the lesson that my facilitator teach while i’m in class. remove and insert loops are really useful to me. I can understand the code even more, after my teacher tough this to me. I admit that i used to get stress, when ever i want to insert or remove anything from my code club projects, but i am really thankful to cindy who tough me this. another good thing is that, we have code club project, so i don’t have to worry much about the lesson that i missed, because are only focus on the project, which they will tell us the instruction what to do. at the end of the code club, there are challenges in each project, so it is a good way for me to play around with my code and see how much i can do. other than code lesson, we learn about editing video using Adobe premier pro! it is very exciting. even i’m not the class at that moment, but i will be able to understand it using tutorial through Youtube and my friend! I would love to try something bonus like this, in every round. doing this, help us to release our stress too.

Random lesson ( Science )

Have you ever thought about heavy objects dropped before the lighter one? I always think about that. However, you’re wrong. All of the objects will always drop the floor on the same time no matter how heavy it is. You can go and experience it now! Be mindful that, if you use the paper and leave, it might not accurate, because the wind might blow it. Use something that is strong than the wind. Example, pen Vs scissors, books Vs rock, wood Vs books. Saying this, make me think about motion. You know what? You need to use motion in order to drop and pick up those stuff using force.  A move you make is a motion. Raising up your hand, stepping forward, dropping objects. On the other hand, if you want to move stuff, you will need both motion to interact with force. The force are the pull or push that you applied over an object to be able to move it with your motion. Did you get it? If you don’t understand, feel free to comment!

Now let’s get into solution. Solution is formed by a mixture of two different substances.  The substance that dissolves is called the solute. The substance it dissolves in is called the solvent. For example, salty water is a solution in which the solute is salt and the solvent is water.

Acid and bases. Acid is An acid is an ionic compound that produces positive hydrogen ions (H+) when dissolved in water. Base is an ionic compound that produces negative ion when dissolved in water. We need to balance the acid and bases in our body, so we can be neutral. We don’t want to get too high acid or bases, because it can burn our stomach or poison our stomach. We can measure those two by using indicator, that will tell you the amount of acid or bases that are in your body through pH scale. The scale is from 0 – 14. The lower acid it is, the higher bases it is too. The high acid is 0. The high base is 14. Our stomach is good balanced at 7.3. However, our stomach can handle up to 2pH for acid. Lemon have the highest acid that we can handle. So, we probably don’t want to eat too much of them!! 

  • Sour things = acid
  • Bitter things = bases

Before Vs. After ( Math )

“students working on math puzzle ( angle) “

I always thought that math is hard, and yes! It is hard. Before I learn this new lesson, I don’t know how to calculate the discounts whenever i go to market. There is one time, i went to the supermarket and struggling to find the real amount of money. I am afraid to ask the seller, because they might think that I am dumb. Percentage is always my problem. Sometimes, when I go and survey people, I won’t be able to put those data into a percentage, so I have to go and ask a seniors for my friend who already know how to do it. The same thing in money tree class    ( we learn about how to use and save our money in a correct way ), after I collected my salary, I can not calculate the commission that I’ve got. That’s why i have to ask my teacher every time. I feel like, I am a young born child! However, the time have arrived, we are starting to learn percentage! Now, i can know the discount prices and the commission, so I can freely be on my own for shopping and calculate my own money management.

Another lesson is angle. I can learn a lot of new words for my math class,  so it would make more sense to communicate with our math teacher. Before i know how to measure angle and those new words, I always ask my teacher in a weird way. Which mean, i try to use another word  to describe what I meant, because i don’t know the actually word. However, I hope that she could understand me a lot better, through my vocabulary practice.

Stop giving money to beggars



“A beggar will always be a beggar even if they give him the whole world as a gift”-Persian Proverb.  

A beggar is a typical person who survives by asking for money. As the Persian Proverb states, the beggar will always beg even if you give him the whole world. Have you ever found yourself in a situation with a beggar? How did it make you feel? There are an average of 1000 people begging for money in each country of Southeast Asia. Some beggars are even from neighboring countries. Meanwhile, there are countries that have a lot of beggars problem and another country is not.  In some countries, it is even illegal. Have you ever wondered why? Take Russia as an example, most beggars are addicted to drugs. Another country as China and countries around the world, has at least one beggar who uses the money that they receive on alcohol and drugs. However, Japan and Singapore are not having this problem. Even though giving money to beggars is known as a charity for homeless people, we should ban these actions. If we keep giving money to beggars, crisis action will begin. This enables their potential, they will become more pitiful, and they will get more discrimination from people surrounding them.

Creativity are everywhere. We can use them when we practice every time.  However, if we don’t let a specific person do so, they will not have any new ideas to survive in their daily life. It does work the same compare to beggars. They sit and ask more money everyday. No one would want to hire them to do something, and that’s the reasons why they don’t have any potential and ideas. According to the BBC news from London-based homeless charity, on of the man said “Handing over money to beggars, can have fatal consequences”-Thames Reach. He stated this, because his observations are sure. Not only, beggars used the money on drug habits, but also the drug habits are really addicted to substances such as crack cocaine and heroin. Obviously, the situation are getting worse and worse because of this. It also bring death a lot in 2016 at London. Besides that, there is a good example that we all should do. Taking Jerry and Thames Reach as an example. Jerry used to be a beggars for a long time ago. Along with this,he had never felt so happy. Moreover, he always felt that he want to die, because he had no idea how to use the money in the right way. Other than this, he also used to be in a drug habit. Fortunately, he got help and support form Thames Reach, so he is out from the drug habit and clean from being a beggar. Absolutely, this action shows that helping them to have a better job is better than just keep giving them the money.

All of the people are the same, they will become pitiful once they always get what they want for no reasons. If we are not willing to solve this, we will just keep giving the currency that we find by our own to someone else. As the result, numbers of beggars are rising up unexpectedly by this reasons. However, it is kind and nice to give money to help people, but what if the person use the money into different ways. For instance, the BBC news says that the government of England had quoted, “For 2015 we found the number of rough sleepers on any one night in England has risen by almost 30% in the last year to 3, 569 beggars and homeless people” (pg. 1). This really show that once people always get the money to buy stuff they want by easy way, more of them will just come and try to spare for money. On the other hand, they might think that begging someone for their money is easy than go and find it by their own. Let’s look at my own experience. On 24 November during water festival, I have met a few young beggars. There are two of the them who came and ask me for money. One of them said “Can I have 100R please?” and the other one said “Can I have 500R please?”. Once I gave the money to those two boys, the other just come and do same thing to me. This really annoy me. However, I did give them something else. Guess what is is? I gave them some of the food that I bought from different stand that I’ve walked passed, so they can share with each other. Even so, they are still hungry tomorrow, but they get the food for today. They are kids, they can not just take the money and buy stuff by their own hand! Apart from this, let’s  imagine, if people give them food everyday, will they survive? Will they have chance to use the money for something else that are not useful? Absolutely not.

When one of the person have different living style from us, we always look at them differently. No matters, what the reason is. This, effect our social life. If there’s no one begging for money every day, then there will not be any discriminate against them. For instance, a beggar from BBC news in the 14 documentary stated “I feel people look down on me because of my situation” and “People have discriminated against me because of my situation.” – Jerry (p.2) .This statement is from one of the beggar that BBC had been interviewed. They got discriminate if people keep giving money to them. What if we start to give them opportunity. What if we start helping them to have a safer place to live. It is even better than just let them sit anywhere for money. In addition, people will just walk past them and make them feel bad for every situations that they meet. Obviously, discrimination means a lot to them. In the other hand, they also have heart, so if we want them to have more chances and stop being depressed, don’t give money to them, but do give something else.


As a conclusion, giving money to beggars should be ban are not a bad idea. This is not mean to make them or hungry or anything, but we are trying to make the community more organized. Here are some of the ways you can do to help practicing this action

  • Give the beggars food, water or clothes instead of money
  • Donate money to the beggars organization, so they could help to take care the beggar in the right way ( including the disability beggars and normal people)
  • Hire them to do something that they can do

I would feel very happy and grateful if we all do these above. I’m sure we can do it.

Outdoor leadership

this round, I have join an exploration called, outdoor leadership. this exploration have touch me a lot for my life survival including CPR, how to have have water to drink, foods, sleeping in the forest. other than that, I can also learn how to help my friends when they have an emergency in the forest or somewhere that did not have close by hospital. so here are some of the actions and activities that i have done on my trip. 


Carbon is virtually important molecule in carbon cycle. It helps to create a lot of things that we need in order to survive such as, protein, fats, nucleic acids, lipids and carbohydrates. There are approximately 0.04% of carbon dioxide (CO2) in the atmosphere. It is a big number right?, compare to whole amount of people in the universe. I don’t know this before, it was quite interesting to me. When I started learning this lesson, I know that carbon are also present in ocean and freshwater as by dissolved carbon dioxide. One interesting thing is that, carbon is also present in the limestone! ( CaCo3). I used think that carbon are really bad for our environment, don’t you? In fact, it helps a lot. Carbon helps the tree do photosynthesis. When trees do photosynthesis, we all can have oxygen which is one of the thing that we must have so, when ever the sun comes out, the plants and trees will do the photosynthesis. Do you the process of photosynthesis? Well, they always absorb carbon in the day time and release it at the night time. However, have you ever imagine our life without carbon? I thought it would be good if it extinct, but sadly it was not what i thought. When they extinct, these are the disadvantages.

  • Not enough carbon to do photosynthesis
  • A lot of dead stuff, so smell not good
  • No oxygen/ no photosynthesis
  • More waste are building up
  • You could have disease

For loops

Last term, We have studied about some of the basic, so this round we are starting into the first lessons. We learn for loops. we use it to print out data like names, and inputs. we mostly make some of the practices in the class. it was hard for the first time, but after I practice it, things get easier. I really like how to was teach, because I could know more how to create more functions for another project that i would need in the future. Technovation is one of the biggest project that I have join, so I might use python or codding rule for coding my application. I thought coding actually really useful, because it helps my brain to think critically. 

here is the example

  • if statements
  • Else if statements
  • continue statements
  • loops
  • ( we also learn more, but I missed the class for other project )

basically, these are the work that i have done

L = “letter”

Fruites = [‘apple’, ‘bannana’]

For x in fruites:

If x == “banana”:


Print (x) ( it will not print your value because the word ” break ” mean to stop all the code )

Fruite [ ‘apple’, ‘banana’, ‘cherry’ ]

For x in fruits:

If x == “banana”:


Print (x) ( it will print out apple and cherry, because the word ” continue ” is to skips  a value. 

so, this is it! basically, it is to print out data or values that we are given in some points. However, some of them are really complicated, that is why it need a lot of determination. I first, kind of stress out a bit for the lesson, but that’s life. I got to ask my coding teacher clear detail of what I don’t understand, so that I could remember all of the steps and rules.
