Acid & Base

Acid is an ionic compound that produces positive hydrogen ions (H+) when dissolved in water. Acids have many important uses, especially in industry. For example, sulfuric acid is used to manufacture a variety of different products, including paper, paint, and detergent. In addition, acid taste sour. Warning: do not try to taste anything to know whether it’s acid or not because if the food has the acid of 0, it might bring you some harmful consequences.

A base is an ionic compound that produces negative hydroxide ions (OH-) when dissolved in water. On the other hand, a base is an ionic compound that tastes bitter and sometimes slippery. A common product that contains base is bleach. Base is slippery, bitter. Soap is also in a base. Soap, concrete and Deo are all base.

Percentage is not just existed and does nothing…

Percentage is not just existed by itself, it’s existed with a purpose, a purpose of helping people with their remembering, understanding and their comparison. 

Percentage is a number with the symbol of %. It expressed as a fraction of 100. In this class, we also learn how to convert the fraction into the percentage. 

Here’s the strategies that convert a fraction to percentage:

numerator / denominator * 100 

 

As you can see the example above, if you take 16*100/100, it’ll be 16 as a result. 

Here’s another example: 

What’s the percentage of 2/3?

Answer

If you take 2/5*100, you’ll see 40%. One thing that you can do is that you can also do the multiplication first and division after that. For example 2*100/5, it’ll be the same answer. 

Besides percentage, we also learn several rules/strategies about geometry. These strategies help me solving the problem more efficiently and let’s see if they help you as well:

This means angle 1 & 3 are equal and angle 2 & 4 are equal.

Did you learn at least one things from these strategies? I hope so! Personally, I think sometimes we have to find the pattern of doing something, so that it helps more with the future works. Like a quote say, “Work Smarter Not Harder”. 

Python Code

Some people might think that coding is not as important, but guess what? Coding is very important as it benefits our thinking skills. There are a lot of different type of coding, however, we only learn about python. Here’s are some  of the Python’s terms:

 

There are more to learn about Python. “There’s no limitation of learning.”

Decimal

Converting Decimal into Fractions

To make it easy, all you have to do is take the numinator divided by denominator. If it’s go forever, you can stop whenever they wants you to stop. 

The Element of Life

Carbon is the element of life, but why? That’s right because everything made up of carbon! If you don’t know what carbon is, it is a chemical element with the atomic number of 6 and its symbol is “C”. It reacts with oxygen. It also produces carbon dioxide by burn in the air.

We did the experiment of black snake.

Procedure:

Put some 20g sugar and 5g sodium bicarbonate in a beaker and mix them thoroughly. Place a plastic tray on the table and cover it with aluminum foil. Place the aluminum tray in the middle of it and fill with sand. Place a mixture of sugar and baking soda over the sand and use the beaker to soak everything with alcohol and you’re ready to go. Fire it all up using the matches.

Result:

When you light it, it forms the ashes combination and forms this shape. According to my research, it says “The sodium bicarbonate produces carbon dioxide gas, while the sugar creates carbon containing ash” and that’s true!

Story Structure & Photography

Brain and Heart are stronger than rules

In the year 2000, there was a girl living a community. She has a very strong passion for entrepreneurship. Every day and every night, she only held her computer researched about becoming a successful people and figured out what product should she made. One day, there was a new law says that women can’t be an entrepreneur. Because of that, she broke the rule and pretending that she is a man. Because of that, she could continue making her amazing social product which is a new and better version of Google. Because of that someone exposed and reveal that she is a woman in her social media. Because of that, she got caught. Because of that, she got punished, but because of her amazing product that helped people a lot, they changed their mind. Because of that a lot of people used her product as a helpful resource. Because of that everyone respects her. Because of that society realizes that girls are also powerful. Because of that, her products are spread around the world. Because of that, she was famous and becoming a successful person. Until finally, the laws change that woman can also be an entrepreneur.

After you read this, you might recognize the structure of the way that it was written. There are many different types of story structure but Pixar Story Structure is the story structure for the story above. There are five steps to do it: 

Basically, this is one of the types of Digital Storytelling. Other examples of Digital Storytelling are videos, photos, recordings, etc. In our class in this round, I’ve learned two particular types of Digital Storytelling; Story Structure and Photography. I really love photography and I’m so excited learning about this essential. On week 2&3, we learned about composition tips. They are:

  • Stright Horizon
  • Rules of Thirds
  • Head Room/Lead Room
  • Symmetry
  • Depth
  • Frames
  • Leading Lines

The week after, we learned about some basics which are:

  • Exposure

Social Justice – Literacy

There will be different themes in every round of English Literacy essentials. This round ’s theme is “Social Justice”. Social Justice is a concept that is related to the different types of justice between individual and society such as wealth, rank, etc. For the first few weeks, we focused on the topic of “Pollution”. We did some research about how pollution disproportionately affects people who are poor and members of racial and ethnic minorities and how members of ethnic minorities got affected by pollution than others. We also have words of the week which are:

An environment is very important not only for me but also for society. We did the writing about pollution in our community as well. I wrote about pollution in my province which is Kampong Cham province. It is located in the center of Cambodia. Here’s what I wrote about my community:

Pollution and Environmental Justice in Kampong Cham

Kampong Cham has a very beautiful city that everyone always think about, but people ignore one crucial problem about this province. Most of the provinces in Cambodia produce a lot of pollution, including Kampong Cham. The source of pollution mostly comes from human activities and they might not be getting enough education about the serious effect of pollution. The town and rural areas are covered with trash that only has been thrown, but not picked. Nothing will be fine if people keep repeating what they are doing right now.

Pollution in Kampong Cham mostly spreads over rural areas around districts. The city in this province might have less pollution than the rural area because there are a lot of factories surrounding the rural area. As I knew before in the province, there’s no landfill or damp, in fact, a few people started the idea of throwing the trash near Sala Chen market which causes others to throw at this place too. One of the big problems is throwing the garbage that concentrated near the station where they sell food, which leads the pollution from the garbage spread to the food. Therefore, it could affect people’s health through the food that they ate and it could lead to a serious health problem. This is one of the pollution sources that have been spread to the whole city.

In addition, there is a factory that located in Cherng Prey district. The workers produced more and more pollution through the air to the neighborhood. Obviously, there is an air pollution that produced from the smoke of the factory. Sometimes, I think it is kind of unfair when people who stay close to the factory got affected. I haven’t heard any solution for this yet, but I hope there will be one.

Moreover, Mekong River is also a source where pollution existed. There are a lot of people selling their products near riverside especially Food Selling. After they ate, people leave their trashes all over the river bank. Not only this, people who live close to Mekong River also threw their huge amount of garbages into the river. The pollution from the trashes spread to the freshwater species and it also affects the fisherman(s)  as they’re going to eat those species. No one realizes these situations that had happened into the province and country.

Nothing surprise saying that transportation is one of the pollution sources that existed in this crowded city. As I visit my community, a lot of pollution of smoke from cars and motorbikes spread to the city population. There are a lot of wealthy people that use cars and motorbikes, which is so rare that they use bikes in this generation. Air pollution is all over, it really needs solution!

Both city and rural area are affected by pollution. In the city, the main sources of pollution are the Mekong river, Sala Chen market, and transportation. In rural areas, the main sources of pollution are from the factories. People wouldn’t think it is a very important problem that needs a solution. In my opinion, this situation is unjust for people who live close to those places. For some reason, people who throw the garbages, just because they weren’t the one who gets affected if they’re not living near that places. I would say some of them are rich as well.

Finally, the growth of this province is starting. Everyone starting to have a campaign where they’re trying to reduce the trash. I think the provincial office is also trying to create a secure environmental justice for Kampong Cham. I’m glad that students putting their effort once a week to pick the trash from their community area, which helps Kampong Cham a lot.

The week after, we did some argumentative writing of the topic that’s we’re passionate about that related to our exploration (project-based learning) or the topic that related to SDGs. First of all, we were taught how to write a thesis statement. So What is a Thesis Statement?

  • Thesis Statement is...

Starting the introduction with thesis statement would be very helpful for the reader to understand our main point. Writing an argumentative would be very fun and an important experience for me. I’m looking forward to seeing my argumentative essay done!
