Koh Pich 2003 vs 2019

From years to years, there have always been developments in a country. So, has Cambodia? Phnom Penh is a city where growth can be seen. Koh Pich, an island in Phnom Penh can prove that this country has really become a better place. In 2019, a land that was barely seen with houses has covered with beautiful buildings and roads. In just 16 years, this place has evolved so much from 2003 until nowadays. 

Koh Pich 2003 vs 2019

Acid & Base

March 2019, 2:00 pm

There was a day in March where we had an experiment. The experiment about acid, an ionic compound that produces positive hydrogen ions (H+) when dissolved in water and base, an ionic compound that produces negative hydroxide ions (OH-) when dissolved in water. It was the day where we understand more about these two substances.

Bleach solution is missing in this picture.

That day we were instructed to pour 20 milliliters of each solution into each cup. Those solutions were lemon juice, vinegar, sprite, water, toothpaste (with water solution), baking soda (with water solution), and bleach. We were told that these solutions represent different pH levels. 

Later on, we poured the red cabbage indicator into each solution’s cup. Then we noticed the changes in color. 

The clear sprite has turned into light red. The light blue toothpaste solution has turned into light purple. The other solutions also changed colors. 

The final step that we did was to combine those solutions that were mixed with the indicator, together. We blended lemon juice with bleach, baking soda solution with vinegar and sprite with toothpaste solution. The result that we got was that they changed colors again. 

 

The red lemon juice solution and light yellow bleach solution has turned into a red solution. This is because the solution has more acid than the base. 

 

 

 

We were then asked to write a theory about this experiment and this is what I’ve written. 

The reaction of acid and base is called neutralization where the products are water and salt. This neutralization helps to balance the solution but it depends on the concentrations of the acid and base in the solution. If you mix a high acid with a high base, it will produce water and salt and the solution will more likely to become neutral. If you mix a high base with a low acid or a low base with high acid, the solution won’t balance but it still produces water and salt. However, it will also contain a higher concentration of one side because of the leftover acid or base which makes it still be acidic or basic. 

The Experiment has End!

Angles in Triangles

Triangle is a shape that forms of three sides and three angles. There are different types of triangle such as isosceles triangle, equilateral triangle and more. However, one fact about the triangle is that the sum of the three angles will always be 180 degrees. Therefore, it is easy to find the one missing angle. 

To find the missing angle, we just need to subtract the two angles that are being shown from 180 degrees. For example:

 180 – ( 23 + 124 )

180 – 147 = 33

So, the missing angle is equal to 33 degrees. 

What We’ve Been Doing? – Math

Math is a complicated subject to learn. Therefore, we have to find the right resources and strategies that can help us learn easily. In math class, we’ve been studying from Singapore Math Books and now by the end of this year, we have finished Primary Mathematics 5B. 

Not only studying from books, but we also learn from online resources. Every week, we have homework that is due on Monday in Khan Academy, an online website that you can learn about different subjects. This is a really helpful website because you can keep track of what you’ve been learning. Besides, at the end of every term, we have a celebration of knowledge, a quiz to test how well you understand the lesson. Because of all the great resources and strategies, we were able to understand math easier and study with pleasure. 

In round 5, we were focusing on different lessons but the one that I enjoyed the most was the intro to algebra. Algebra is a part of mathematics where unknown numbers are represented by letters. For example:

6x + x – 5

5 – x

3x + 2x

Because I’ve learned algebra before, I find it is easier to learn this lesson. Below is the exercise I’ve done before. 

Algebra Exercise:

3(x+5) = 33

3x + 15 = 33

3x = 33 – 15

3x = 18

x = 18/3

x = 6

Marine Traveling Theater

 Marine Traveling Theater is an exploration where we performed a short play that we’ve created about ocean threat which our goal is to encourage people to conserve and protect marine life. Our facilitator for this exploration is from Marine Conservation Cambodia (MCC). 

Before we can create a play that’s related to the ocean, we have to understand marine life and it’s ecosystem first but also the theater. We spend our first two or three weeks trying to have general knowledge and idea about these two subjects including ocean threats, marine ecosystem services and roles in theater. We even go to explore underwater life through snorkeling to see the beauty of the ocean but also to understand more about it. 

During our trip to Koh Seh, we were able to do lots of many things. Some of the activities include dolphin survey, snorkeling, picking up trash but also seeing the bioluminescence. While snorkeling we saw seahorses, starfish, beautiful coral reefs and many different kinds of fish. I then realize the outside beauty of the ocean has nothing compare to the beauty inside the ocean. I’m really grateful to be a member of this exploration. 

After learning about these things, we were able to divide roles in creating this play. Some of the theater roles include director, actors, costume designer, screenwriter and many more. My job in this exploration is a media director with one of my classmate. We are the one who created the poster, the pamphlet, and other technology products to advertise our play. After all the hard works that we’ve done, we were able to create a play called New Beginning. 

New Beginning

A little girl finds out that her beloved ocean is being polluted: the adventure begins! Will she be able to make a change toward pollution or will this problem continue to impact the ocean?

Performances

Because our play is about protecting the ocean, we chose the people around the coastal area to be our target audience. We were able to present to Sala Monkey and Kep Garden in Kep. 

 

To make our play more influence and effective to the kids, we decided to do an activity about ocean threats with them. We explain the effects of ocean threats and give them a chance to find the solutions they can. 

 

 

 

We also got the opportunity to perform our play on Ocean Day at Trapeang Sangkae Community Fisheries. Because of all the opportunities we got, we are really grateful that our play has reached out to many people.

Help Protect Our Ocean!

Simple Acts of Throwing the Trash in the Bin & Reducing Single-use Plastic Can Help Save Our Ocean!

How I Change Cambodia – Marine Traveling Theater

Humans need oxygen to breathe which the ocean provides more than 50% of it but people don’t realize. We eat fish to stay healthy which is given by the ocean but we never appreciate. We make money from turning a place into an attraction for tourists which is the ocean but we never take care of it.  One day, all of these amazing resources and services that the ocean gives us will be gone because of human. 

Ocean Threats

Illegal Fishing – Trawling

Every day, there are people who do fishing in illegal ways. In Cambodia, trawling is very popular but only allowed when it is deeper than 20 meters. However, people usually don’t respect the rule. Trawling in shallow water can cause damage to the ocean surface such as destroying the coral reefs and seagrass which are the marine habitats for many different kinds of fish to secure themselves from their preditor. Besides, these habitats also provide food for some of the marine animals. Imagine, if these habitats are destroyed, how would the animals that depend on the coral reef and the seagrass survive? I can say they would barely live in this situation. Moreover, there is even an electric trawling which is much more harmful than the normal trawling. Electric Trawling will grab all the things that are on its way even if they are small fish. After the fish are being collected from electric trawling or from trawling, the unwanted or unneeded fish that have trapped and died already will go back into the ocean. In this state, the population of the fish will be reduced. 

Coastal Developments

When a place becomes a tourists attraction, there will be developments happen in that area. For the ocean, there might be a bridge that will cross to the island just like Koh Pous Bridge. There might be buildings around the coastal area or on the island. Building these things aren’t always good as they look like. For example, building the bridge that crosses the ocean can destroy the ecosystem that is underneath it. The bridge might be built on the beautiful coral reefs or seagrass which will cause damage to these habitats and other fish. Therefore, we need to consider it deeply before doing any coastal developments. 

Ocean Pollution

It is common to see people throwing trash everywhere in the country. But where do these trash go? Well, it will eventually go into the ocean because of the wind. In Cambodia, some of the trash that can be found in the ocean are plastics and ghost fishing gears. Usually, marine animals such as sea turtles will confuse plastics with their food and so, they will eat those plastics. Consuming plastics won’t give you any protein or energy. Besides, it will harm you. Therefore it is really dangerous to have plastics in the ocean. While plastic can threaten marine animals, so can the ghost fishing gears? Fish can be trap in the net that has been left in the ocean from the fisher which considers being ghost fishing gear. Because the fish can’t go anywhere, it can die from starving. There are also other ghost fishing gears such as fishing tackle and many more. This ocean pollution problem can also reduce the population of the fish. Also, trash can decrease the beauty of the ocean. Therefore, will the polluted ocean attract as many tourists as it did before being polluted? 

Illegal fishing, coastal developments and ocean pollution are the main costs of ocean threat. If we don’t do anything to stop or reduce these activities, our ocean will get destroy one day because of our inconsideration.

New Beginning

A little girl finds out that her beloved ocean is being polluted: the adventure begins! Will she be able to make a change toward pollution or will this problem continue to impact the ocean?

We chose to create a play about ocean pollution because it is the problem that can be solved through the acts of throwing the trash in the bin and reducing single-use plastic. We believe we can influence people to do these actions through our play while illegal fishing and coastal developments need more movements. 

What Have We Done?

Because our play is about protecting the ocean, we chose the people around the coastal area to be our target audience. We got a chance to present our play to Sala Monkey and Kep Garden which gave us two performances in Kep. By performing our play to the kids, we hope that they will understand about it and pass the information to their families and other people because we believe that kids can make a change. 

 

To make our play more influence and effective to the kids, we decided to do an activity about ocean threats with them. We explain the effects of ocean threats and give them a chance to find the solutions they can. 

 

 

 

We also got the opportunity to perform our play on Ocean Day at Trapeang Sangkae Community Fisheries. Because of all the opportunities we got, we are really grateful that our play has reached out to many people. 

Finally, we hope that we can make a change toward ocean pollution through this play and people would take action altogether.

Mango Picker

Six Simple Machines

 

Inclined Plane

A type of simple machine that uses for moving things upward or downward.

 

 

Lever

A type of simple machine that the force is applied at a point that gives the output at another point. Ex: scissors, etc

Wheel and Axle

A type of simple machine that consists of two circular objects with an axle in the middle which usually is used to move an object.

 

Wedge

A type of simple machine that is used to split and cut things. 

 

 

 

 

Pulley

A type of simple machine that consists of a wheel and string attached to it. Usually, it is used to lift things up. 

 

 

 

 

Screw

A type of simple machine that the inclined plane is wrapped spirally around a shaft. 

 

 

 

Mango Picker

Just by seeing the name, we know that the Mango Picker is used to pick up mangoes but for a long distance without having to carry a heavy dustpan that is full of mangoes with you while collecting them. It is a compound machine that composes of three different types of simple machine which are wheel & axle, lever, and inclined plane. This Mango Picker project was inspired by the situation in our school where there are full of mango trees and those mangoes are falling down every day. We always have to collect those mangoes and put them in the dustpan. After the dustpan is full, we have to throw them into the trash bin which is at least three meters far from each other. We have to repeat this process, again and again, several times until all the mangoes are being collected. It is really tiring to keep doing that because when the dustpan is filled up, it is heavy due to the weight of the mangoes. Therefore, our team has come up with the idea of creating this Mango Picker. The Mango Picker uses wheels to reduce the force that is needed to move the dustpan and the inclined plane which make the mango rolls down into the box. It uses the lever to help the mango moving too. We have created a prototype that is made out of papers and bottle caps. In overall, I think that this project is really fascinating and educational but also at the same time it is fun to learn. 

Bastard – Book Review

Deciding and planning what you will be doing in class is called independent learning, and that’s what our Literacy class round 5 was about. The students were given the opportunity to choose their own novel to read, decide their own topic to write and organize their own time in class. I read a novel titled Bastard, a comic that reflects on a sentence that says it’s not too late to start over.

Title: Bastard

Author: Youngchan Hwang & Carnby Kim

Rate: 9.88 (Webtoon)

Numbers of Episode: 93 Ep

 Main Characters: 

 

Jin Seon

A son of a murderer (Dongsoo Seon), who’s been an accomplice in his father’s crime since he was young. 

 

 

 

 

Dongsoo Seon

A serial killer who murdered girls but also people who get in the way of achieving his goal. 

 

 

 

 

Kyun Yoon

A transfer student who’s been always on Jin’s side. She is someone who changed Jin’s life. 

 

 

Jin Seon is an ordinary high school student who’s been bullied by other high schoolers because of his one glass eye and his quiet personality. One day Jin was harmed by other high schoolers and needed to be saved immediately, because of the help from Kyun Yoon he was able to go to the hospital safely. His father, Dongsoo the CEO of G Corporation and also known as the philanthropist in the society, accidentally saw Kyun on his way to Jin’s room in the infirmary. He then was attracted to the willingness to kill Kyun while Jin started to protect her. 

Jin Seon & Dongsoo Seon: 

Since Jin was Young, he thought that his father was the one who drops Jin off the building which makes him weak and lost one of his eyes. He also thought that his father will kill him whenever he is useless to his father, because of this thought Jin was scared about telling anyone that his father is a serial killer. Moreover, will Jin be able to accept the fact that he will be put in jail for a certain amount of time because of all the crimes that he’s cooperated with his father unwillingly if he testified all the things to the police? He kept this thing to himself, the fact that his father is a murderer, and a demon is what Jin knew his father as. 

Jin Seon & Kyun Yoon: 

Kyun Yoon is Jin’s girlfriend. They met each other when Kyun helped Jin from the bully. Since Jin was young, he always had a nightmare of falling off the building but then Kyun changed his dream. Kyun is helping Jin from falling off the building and being a light that shines across the darkness. She always stays on his side and believes that even though Jin is weak but he’s not a bad person. Jin was really afraid to tell Kyun the truth because he thought that Kyun will hate him if she knows the fact that he’s been an accomplice in his father’s crimes but when the time came, Kyun knew everything but still accepted it and stay on Jin’s side because she believes that it’s not too late to start over. 

Dongsoo Seon & Kyun Yoon: 

Dongsoo has attracted to Kyun since the time he ran into her in the hospital. However, Kyun never knows about it and respects Dongsoo as her elder. Dongsoo has also asked Jin to help him getting Kyun but Jin refused. In the end, Kyun knew everything from Jin and scared of what Dongsoo is doing. 

Favorite Part:

At the very end part of the story, Jin had cleared all of the confusions he has with his dad. The one who threw him off the building wasn’t his dad, it was his mom. The reality was his dad never intend to kill him but still, he is a demon who is a serial killer. He had killed a lot of women and also Jin’s friend, Manny Kim. However, Jin has forgiven Dongsoo through the act of not killing him. 

Author Writing Style: 

The comic contains lots of new words that can be used in everyday life. Moreover, the author always leading the readers to unexpected things which make the readers curious what will happen next. 

Conclusion: 

Bastard is a thriller comic where it reflects on the relationship between a dad who’s a murderer and his son. It shows how the son got the courage to go against his father. If you like reading a thrilling or a fascinating novel, Bastard is recommended. For me, this is one of my favorite comics.

This is a mini wheeler, you can use it as a toy. You could change the size and everything but make sure you understand how it is created first!! Below are the steps and materials that you need! Be excited, enjoy!

Above is the introduction to the Instructables Craft, The Wheeler, posted by my team in the exploration called STEMgineering. This small engineering project (The Wheeler) and many other project articles that were written by the students in this exploration are meant to bring Cambodian student’s interest in learning STEM. Besides posting the articles in Instructables Craft, we’ve also gone to 2 different government schools to present and teach them about these projects. It was my first time being able to show what I’ve learned with the government school students and that was an amazing experience for me. Other than creating this wheeler and working with government school students, we also learned a lot of things from this exploration such as the six simple machines and different types of engineers. This is the link to the Instructables website.
