pH soil test

Before we get an indicator of red cabbage, we need to boil red cabbage until it turn to liquid.


Red cabbage is an indicator, if we put red cabbage into a soil the color of the red cabbage will change:

  • When Red cabbage mixed with soil and the color turn pink or light red, which mean the soil is an acidic soil.
  • When Red cabbage mixed with soil and the color turn blueish-green, which mean the soil is a basic soil.   


Start real experiment:

Supplies :

  • Red cabbage
  • Water
  • Pot
  • Big container
  • Cup
  • Mixing spoon
  • Small hole basket
  • Soil

Step 1 :

  • Cut the red cabbage into small pieces
  • Put the red cabbage pieces into the pot
  • Boil the water
  • Put the water into the pot until the red cabbage sink
  • Wait for 10 minutes to let the color come out of the red cabbage. ( It’ll be purple, not red )
  • Take out the red cabbage by using small hole basket
  • Take only the color of the red cabbage ( Liquid only )              
  • Pour the indicator of red cabbage into a big container

Step 2 :

  • Find two separate container of different type soils
  • Separate the soil into two different container.
  • Add 100 ml of water to the two different cup
  • Wait two minutes for the mud to settle.
  • After both cup of water and mud are settle take another two cup to separate the water from the mud cup ( take only 50 ml of water from the mud cup )
  • Put the two cup that has water mud in it put into two separate place


Step 3:

  • Take the indicator ( red cabbage ) add 75 ml of it into the cup that has water mud ( total 150 ml  for two cup )

Step 4:

  • After you mix them together, if the color change to pink or red which mean your soil is acid. If the color change to blue or yellow which mean your soil is base. If the color change to green which mean your soil is neutralization, it is right in the middle of acid and base.

Step 5:

  • Soil that is acid, is the soil that can grow plant well and good for farming.
  • Soil that is base, is the soil that is not really good for growing and farming.

Advantage of computer

Computer was made by Charles Babbage and was made in last 8 decade.The advantages of computers are many.  One advantage is their time saving nature.  It is much quicker to type a letter than to write one with a pen.  The connection to the internet is of great use. The ability to research something or ask questions in real time is amazing.  The amount of data that can be stored, manipulated, and retrieved is phenomenal.There are a lot of major advantage of  computer.Computer is a good technology for learner ,teacher and for occupation.Computer articulate our idea about what we want to know.Computer can help us a lot of thing that we want to do.Computer help us to do something rapidly and  greatly improves the speed of data input, output, processing, and transmission.Also,computer give us an information that we want to know about. Computer is a crucial component of the academic success of a student. Whether it is a laptop or a desktop, a computer offers a unique platform to gain the most up-to-date information  and to analyze the use of that information for school projects. Additionally, computers help students grow accustomed to writing professional material, like resumes when preparing for the workforce.However computer help us to search something that we haven’t know and we want to know. Using the computer save natural resources by limiting our need of paper and pencils..Moreover we can watch video youtube and more in computer.Also,we can use skype to see each other if you have family that live far away from you.Also computer is a good technology to learn explore more at our house without teacher explain.However we can play game that will explore your english what you want to relax.We can put a khmer old song for our parent to listen.

What do I plan to speak?

I plan to speak about Climate action in the world.Also I  divided the main idea to 2 group


Climate action is now affecting every country on  every continent It is an issue that requires solutions for the problems but, I am focus climate action in Cambodia that where am I from.I gonna find the problems about Climate action in Cambodia and how to solve the problems .As some of you in Cambodia know that Cambodian use a lot of energy, plastic bags, can, plastic water bottle  that why Cambodia warming is get hotter and hotter. Also Cambodia have so many factory and that made air pollution to the ozone layer of the sun. The sun ozone get thinner and thinner and that it made the warming get hotter and hotter. However if all around country in the world make this problems sothe earth will destroy one day. Moreover, Weather in Cambodia is change when rainy season the weather made more hotter and hotter but, when summer season the weather made rain and rain almost every day. So it is hard for Cambodian people because when it rain a lot it will flood while it flood people can’t make field because is has much water. Moreover now almost everyday in Cambodia it rain and while it rain a lot Cambodia will flood everywhere. And that might hard for people in Cambodia to buy something, go somewhere and do something . since there was a change in climate, most of fields in Cambodia were not usable for growing such a crop, rice paddy. Actually, in order to make it easier, we should firstly understand what the term of climate change is. The answer is that climate change is one of the most concerning global issues that have severe impacts on human securities.

Solution: people should reduce, reuse and recycle all types of plastic and do not throw any types of plastic to the lake, river and ocean.While we do that in the future our planet will be all green and natural.

What personal connection do you have with this topic?

Yes ,it really connection to my personal not just me also my family,people in my province and in country because nowaday in my province in my country people do affect to the climate change is through the cutting a large amount of the tree or we call deforestation.As we can see  that, forest is the main actor and plays a very significant role in keeping temperature on earth cool. Actually, most of the carbon dioxide (CO2), a main actor in increasing the temperature, is usually absorbed by the trees, and the trees convert such a bad substance to Oxygen (O2) to which useful for human beings. Moreover forest also plays a very important role in balancing the number of carbon dioxide. However what will happen what will happen when a large about of the forest is cut down? Actually, when the number of population increases increases their demand for daily lives also increase Therefore, they have to cut down the forest for building houses, to make land usable for growing crops. As a fact from my research it said the scientifically, when the trees were cut or burned down, the carbon dioxide will immediately go back to the atmosphere. Also we could just burn the plastic bags but, chemicals in the smoke particles get to our stomachs, lungs and eyes it can be affected if we breathe it in . It can cause serious problems for children and pregnant woman . Also, when the gets into the atmosphere, it can damage the environment in the form of acid rain. For the best about that is to not use any types of plastics. If you want to use you can use but, you have to reduce, reuse and recycle all of them. That it won’t make our planet disappear and the planet is become natural. And that is my care for all those problem.


  How does your topic relate to our theme of ‘Creating a Hopeful Future’


Yes, it really creating hopeful future for earth. And There is no question that Earth has been a giving planet. Everything humans have needed to survive, and thrive, was provided by the natural world around us: food, water, medicine, materials for shelter, and even natural cycles such as climate and nutrients. Scientists have come to term such gifts ‘ecosystem services’, however the recognition of such services goes back thousands of years, and perhaps even farther if one accepts the caves paintings at Lascaux as evidence. Yet we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit. The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled. Beyond such physical goods, the natural world provides less tangible, but just as important, gifts in terms of beauty, art, and spirituality. Also green nature help us and our planet very much because,while our planet don’t has trees so our planet will destroy. For us we can breathe carbon dioxide from the trees and while our planet doesn’t have trees so we can’t breathe and we will die. That why it creating hopeful future for earth .Also not just I everyone in the world even you don’t want our planet destroy.


In my own words the meaning of “ discipline” is to stay with something, control, and teach. First of all, discipline means to stay with something. For example, one of my friends has  discipline with her works. She stayed with her work until she finished what she had planned. Furthermore, I believe that discipline means to control because you control your mind or control feeling to do things. A real life example is one of my friends, who lives in my hometown, doesn’t want to do anything like:  homework, or washing his clothes, but he controls his mind that if he doesn’t do it, he wouldn’t have clothes to wear or his homework wouldn’t be done. The only thing he can do is to control his mind to do it. Finally, I believe that discipline is to teach. This is because you are the only one who teaches yourself to do something that you need to do because no one can control your mind. To finish something that you need to finish,  you have to teach yourself how to have discipline with your work. To sum up people may define the meaning of discipline differently, but for me discipline is to stick with your job, manage your work, and train yourself.

Why do we need education?

Education is a main point in people life. People always study from birth to death. People try to study to because they want to get high education. Studying never ends. There are many categories in education, which is math, science, chemistry, history, and more. Each subjects helps you to learn a lot of of things that you didn’t know before, and it helps you to make your life easier. For example, history class may help you to learn good things from the past period. However, math helps you to calculate the amount of number. However, there are several advantages of study.

Firstly, people study to get a good job or to own a company. If we don’t study, we won’t get a good job or own anything. If you want to get a good job, the only thing you could do is study hard. When you study hard, you get a high education. You know a lot about the positive job to do. When you study harder, you will success the action. Also, it is easy for you to have a good job or to own the company by your own skill. That is a good point of study to get the good occupation.

Secondly, people who study hard will becoming a change agent. When you study a lot about skill or each subject, you get to know a lot about something deep, that not a lot of people know about it. If you want to change your country, you have to have a high education to make your country develop by using the creative way. For example, people who raise animals, they don’t really know a lot about the advantages of cow poops, but if you are the learners, and you have a really good education, you might use the creative way that you study to turn cow poops into something useful for your country and export them to other countries to get  money to develop the country. That is a example of change agent people.

Finally, people study to live in peace and happiness. When you have low education, you don’t have a good job to do. Most people who study hard don’t really worry about how their future looks like. They think in their mind that, they have high education, and they might have a good job to do. Also they would have a happy family. For people who have low education. They always think about their future of what they can do to get money to support their family. Those are the differences between how people live with a different level of education, and how hard people who study hard look like, and how easy people who have high education life look like.

All in all, you need to encourage people to study hard, to have a good education and then they will have a good occupation, to become a change agent and to live with happiness. Also to make them have more power to study.



Elephants are very clever and are the biggest animals on the earth. They are found in Africa and Asia. Generally, they are a grey color and they are white in Thailand. Female and male elephants live in separate groups. Elephants live a long time, more than 100 years. Mostly they live in jungles, but they are also seen in the zoo and circus. They can grow around 11 feet in height and 5,896 Kg in weight. The largest elephant ever has been measured as 3,96 M high and weighed 10,886 Kg. An individual elephant can eat 181 Kg of food and drink 30 L of water daily.

Elephant skin is one inch thick; however, it is very sensitive. They can hear each other’s sound from a long distance, around 8 Km away. Male elephants start living alone when they become adults; however, females live in groups. The oldest female of a group is called the matriarch. In spite of having intelligence, excellent hearing powers, and a good sense of smell, elephants have poor eyesight.

Elephants look very attractive to kids because of their interesting features: two giant ears, two long tusks (around 3m long), four pillar-like legs, a long trunk, a huge body, two small eyes, and a short tail. Tusks are believed to grow their entire life. The trunk is used to eat food, drink water, bathe, breathe, smell, carry loads, etc. Elephants are considered to be very smart and never forget any event that happened in their life. They communicate to each other in very low sound.

The baby of an elephant is called a calf. Elephants fall under the category of mammals as they give birth to a baby and feed them milk. A baby elephant can take almost 20 to 22 months to reach full development inside its mother’s womb. No other animal’s baby takes such a long time to develop before birth. Female elephants give birth to a single baby every four or five years. They give birth to a baby that is 85 cm (0.83m) tall and 120 kg heavy. A baby elephant takes almost a year or more to learn the use of its trunk. A baby elephant can drink about 10 liters of milk daily.

Elephants are at risk of extinction because they are easy to find, they have prized ivory tusks, and they are targets for hunting. They should be protected in order to maintain their existence on the earth. Why we have to protect elephants? Because in use future people might want to see elephants and want to know how elephants look up close and live. Also elephants are good for other animals that depend on them. Elephants are just amazing animals that needs our help



An environment is gifted by the nature to nourish the life on the earth. Everything which we use to continue our lives comes under the environment such as water, air, sunlight, land, plants, animals, forests and other natural things. Our environment plays a very significant role in making possible the existence of healthy life on the earth. However, our environment is getting worse day by day because of the man made technological advancement in the modern era. Thus, environmental pollution has become the biggest problem we are facing today.

Environmental pollution is affecting our daily lives negatively in various aspects of life such as socially, physically, economically.  Contamination of the environment brings lots of diseases which human being may suffer whole life. It is not a problem of community or city, it is a worldwide problem which cannot be solved by the effort of one. If it is not addressed properly, it may end of life a day. Each and every common citizen should involve in the environmental safety programme launched by the government.

We should correct our mistakes and  towards our environment to make healthy and safe from the pollution. It is hard to believe but true that only a little positive movements by everyone may bring a huge change in the declining environment. Air and water pollution is leading our health on danger by causing various diseases. Nothing can be said healthy nowadays, as what we eat is already affected by the bad effects of people which reduces and weakens our body  to fight disease causing microorganisms. That’s why, anyone of us can be diseased anytime even after being healthy and happy.

So, it is a major worldwide issue which should be solved by the continuous efforts of everyone. We should participate in the World Environment Day campaign to actively participate in the environment safety event.
