Past tense and Irregular verb story

To practice the past tense and irregular verb, I wrote a short story in past tense about one of my favorite childhood memories. The paragraph below is my story:

About six years ago, I was a grade four student in my local government school in Takeo province. I walked to school throughout my life as a student since the start of the first grade to the end of 3rd grade academic year. Sometimes while I walked from school back to my home, I felt upset about myself because I did not get access to transportation so I couldn’t go out with friends. however, rather than allowing this problem to stop me from working hard, I kept myself strong and instead I pushed myself to tried harder and helped with my mom’s business more and more. I was shocked when I saw my dad bought a brand new bike as my birthday present. At that moment, he made my dream came true, so I grabbed his face and kissed him for the first time of my life. At my first day of 4th grade, I rode my bike to school for the first time. When I rode my bike, I thought about all the work that my parent has put into getting this bike, which made me cried every time I’ve thought of it.

Learning how to a better waste management

After the exploration end, so I started to work on project as an expertise. This is what I usually felt at Liger, there were many wonderful projects that has stop as the exploration end. Nothing big happen or other word the exploration taped haven’t complete the mission. I said to myself that I can’t let this one happened the same as the other, because the potential changes that this project could bring o the world is big. The mission is to create a liable cost compost design that both strong and large storage. Therefore, in this expertise, we kind of approached two main path to do this. The first essential thing that we did is finalize the design and calculate the price of all type of materials. Second thing that we also did is working planning a system that would work for the school. Sorry to say this, but the school aren’t do a good a job at compost our own house wastes. We are trying to help other, but we haven’t help ourself. So currently we have the first prototype, which is cost about 50$ for a size of 1.5meters square and a height of one meter. This size can store at least 200 kg of compost. I have come across and realized that inventing an effective design is not easy, there are many aspects to it such as the strength, foundation and appearance. But, the best thing is that we can always make changes to it to make the best of our ability. We only have one hour a week, and if we want to see this change our community, we have to push through our own time.

Nefarious….

As I carefully entered the haunted house, the door shut behind me and I saw a shadow walking behind as I walked. I was terrified, my heart was pounding rapidly. As I continued to walked, a creaking noise came from above my heart. Spine-chilling wind blew across my pale face. It seemed that there were eerie footsteps following me as I examine the dark corridor. “Is anyone out there?”, I screamed from far away. A moment of silence, the creaking noise and the shadow were gone. All I heard was my own heart beat. “ARGH! WHAT THE HECK WAS THAT?” I shriek. There is a gross slimy cold hands that has this putrid aura to it. I screeched a kitty on the table and suddenly it turn to be an repulsive creepy woman. It’s look like a evil bloody rapscallion. It has huge slimy eyeballs with blood running down its face. There were no nose but long sharp teeth were sticking out of its mouth. I have no clue what I was going to do next. I can’t even screamed or move my legs. It’s like sleep paralysis where I can’t do anything, After that monster scream, I manage to run away, I then feel extremely confident and tell her to go and take shower. She denied my request, I was so mad at that ghost, so I decided to carried her and threw her into the swimming pool, “SPLASH!” Hehe. The swimming pool turned red because of the blood. I though she is already drown but she did come back up and pulled me into swimming pool too, But it turned out that, I was on my bed.

Scarcity and Choices

I love learning about economic. I think that economy involve in everything we do in life, making choice, spending money, etc. Learning economy has help me a lot with deciding the best choice and always aware of what to spend my time for. Personally, economic is the study of scarcity and choice. It is basically study how individual, firm and society deal with scarcity. Because, I thought that economic is a very essential subject to know, I decided to spend most of my free time to learn all of these through various sources such as Edx, my learning facilitator, ACDC econ youtube video, and mainly from the textbook called the Krugman_s Economics. There are two main types of economic, microeconomic and macroeconomic. My favorite economic division is the macroeconomic because it a study of a large economy as a whole or economic aggregate (the whole amount). From all what I’ve learned so far, the two main three main takeaways are trade off, opportunity cost and TINSTAAFL (There is no such thing as a free lunch). I believe that economic will help me to make a better decision in life and gain my skill as a leader.

Creative Technology Expertise

This engineering expertise is not like other, it is called the creative technology, meaning that it includes five main subjects, which is science, technology, engineering, ART and math. From all of these subjects, the most focused subject area for this expertise is the art of design. Design is the most important aspect of engineer, everything need design, from the frame/shape of the object to the very tiny complex electronical part. Getting the right design for a system will make those product run smooth and have the least error, which is the key to success. There are a lot of critical thinking involving in this expertise. Finding problem is also very essential when testing a prototype. These past few weeks we had working on designing an Arduino car frame and reprogramming the micro-controller. We had build a lot of electronic skill building such as learning how to code (Javascript) and electronic circuit.

The poem that kill me

After many problems

With bordering countries

and French colonization,

Cambodia rose up again.

Again after the “Angkor Wat” Empire

Many considered as the “Golden Age,”

Which was controlled by Sihanouk.

 

Can you imagine how it feels like?

A modern city, with a high education system.

Music was diverse, like in an ecosystem.

Banks were created, the economy expanded.

Overflowing with optimism and hope,

Dancing freely, people enjoying entertainment.

Internationally, they knew who we were.

Awesome, peaceful place – Cambodia.

 

Dreadful massacre happened unexpectedly.

Eventually, everything was ended.

Are you educated, an actress, indigenous, wear glasses?

Then, your eyes will close with sorrow.

Humans were forced to work, 12 hours a day.

Starvation snuck in, leaving the land dripping with death.

 

Phnom Penh became a ghost city.

Over 3 years, 8 months, 20 days.

Lives of animals were meaningless.

Poverty was rising at a 100% rate.

Obey each other to leave the country for safety…

They left behind the brutality of POL POT.

 

Do NOT step on the same footprints!

Or else, people will die in sorrow.

Learn from the past, improve tomorrow,

Think carefully before you take action.

Do NOT be evil like Pol Pot!

This I Believe

This I Believe that education is the secret weapon that helps to fight through obstacles to have a successful life.

My uncle has been struggling to find a good enough job to support himself and his family. Nith was an excellent uncle to me. He cares about me, and he always looks after me. Uncle Nith was always being push to study from my grandpa, but he was then repelled because he wants to enjoy his time with his friends. The consequence of this action is that he can’t get a good job that will provide enough salary for him to live a happy live. He tried to apply for five different jobs, but no one is interested in him. This happen because he doesn’t have the secret weapon to fight the problems that they gave him, meaning that he doesn’t have the education to fulfill the company needs. Uncle Nith moved to Thailand for six years already. The reason he went there is that there is a job opportunity for him and now he is a driver for one of the company in Thailand. By doing this, he had sacrificed many things such as break out from his parents, family, live there alone without knowing any language and culture.

After seeing what had happened to my uncle, I realized what I couldn’t believe was becoming true. My family tried to take my uncle as an example to proof that I must study harder. At that time, I was so careless about my learning, meaning that after I came back from school, I would throw my back on my bed and turn on the TV to watch my favorite movie Sen Ou Kong. My dad usually come back from work at around 8:30 to 9 o’clock at night with tired eyes, hungry and worriedness about me. The quote that he said to me every night is that “I learn so hard to stand where I am today and at the time, I didn’t have any electricity, no really school, no transportation, no anything. And work every day, to provide you the money and everything for you to learn and you don’t even learn, then what is your future going to look like? I can help to provide material, but I can set you, future son.” This quote has stuck in my hard until now and this quote is always pushing me to study harder.

At that time, I was in grade four and I was doing okay in school, but I was not a good student. I always play in the classroom, didn’t do homework most of the time and always went out with my friends after school. After I saw my uncle and many others people who don’t have education life and my father quote every day, it had inspired me to become a better kid and a better student. Therefore, I began to think of a few things. One thing was that my uncle experiment shows me that education is very important and I need to have that weapon as soon as possible because I will need to use it one day. So, I started to learn more at night, do all the homework and focus on school more. Moreover, when I have free time I helped my mom with her gasoline business and read more book as well. After I did that for 6 six months, my learning and my grade are significant difference.  I never know when I will need my knowledge, I have to study hard everyday to fulfill my dream. Surprisingly, in at the start of 2011, Liger Learning Center school came and recruit the potential student to learn at their school. Because of my hard work, out of over 12,000 students, I was selected to be a student there with a full scholarship. This achievement proofs me that my parent and my believe is true, that education is the secret weapon that helps to fight through obstacles to having a successful life.

After this achievement, I didn’t stop, I even work harder because I believe that my belief is the best path to take, in order for me to complete the task that I want to accomplish. I want to be a change agent for myself, my family and my wonderful country, and to do that I need education.

Distance – Time graph word problem

The distance, time graph show the position of Mrs. Kanha goes to different places from her home. Mrs. Kanha drove to a bookstore from her house to buy some books for her kids. After, her purchase on -the bookstore, she then drove to the gym to exercise so she remains fit and strong. Finally, she drove to her kids’ school to pick them up. The diagram below shows the distance, time graph of Mrs. Kanha.

Questions:

  1. How far is the bookstore away from the house?
  2. How far is the school to Mrs. Kanha home?
  3. Mrs. Kanha driving speed from her home to the bookstore was 8 km/h slower than her driving speed from the school to her home. Form an equation in x and solve it.
  4. Hence, express the time that Mrs. Kanha spent driving as a percentage of her whole journey.

Solution

  1. The distance from the house to the bookstore is 20 km.
  2. The distance from the school to Mrs. Kanha house is 25 km.
  3. First, we need to find the driving speed from her home to the bookstore.

Which give us that speed= 20 km / x minutes

Now, the unit is in km/minutes, we need to time 60 to the numerator to convert to km/hr, so that we can plus it with the 8 km/hr that they give us.

                = (20 * 60) / x

                = 1200 / x

Second, we need to find to the driving speed from the school home.

                Then, speed = 25 / 210-(x+105)

                After we have that, we need to do the same thing to make this to km/hr.

                Speed = 25 * 60 / 210-(x+105)

                =  1500 / 210-x-105

Third step is to take these two values and the information that they provide and turn to an equation.

                The easiest way is to make a words based equation and for this example there are three way you can set up.

                Therefore, the equations are:

                          1. Home → bookstore + 8 km/hr = school → home

                          2. School → home – home → bookstore = 8 km/hr

                          3. School → home – 8 km/hr = home → bookstore

                For this example, let’s pick equation number one.

                               (1200 / x )+ 8 = 1500 / 105-x

                               (1200 / x) + ((8*x) / (1*x)) = 1500 / 105-x

                               (1200+8x) / x = 1500 / 105-x

                               1500x = (8x + 1200)(-x + 105)

                               1500x = -8x^2 + 840x – 1200x + 126000

                               8x^2 + 1860x – 126000 = 0

                               (8x^2 + 1860x – 126000) / 4

                               2x^2 + 465x – 31500 = 0

                Now, we need to solve of x, there are many way we can solve of x, we can factor, graph and solve it or you can use the quadratic formula to isolate x.

                             For this example, let use the quadratic formula because the                                   other option is very hard to deal with huge numbers.

                                  Coefficient are: a = 2 ; b = 465 ; c =-31500

                                  Quadratic formula: x =  -b +- sqrt(b^2 – 4ac) / 2a

                                  Plug it a,b and c:  x = -465 +- sqrt(465^2 -4(2)(-31500) / 2(2)

                                  Solve: x= -465 +- sqrt(216225- -252000) / 4

                                  x= -465 +- sqrt(468225) / 4

                                  x=54.817 or x=-287.317 (rejected)

                         So, x=54.817 because there is no negative time.

4. To figure out Mrs. Kanha total driving time, we need to find out her total time of her journey and minus it with her rest time.

                 Find her total time: x+(x+46)+(x+97)+(x+105)+210

                 Plug the value of x in: 677.27 minutes

                 Her total time = 677.27 minutes

                 Her total rest time: (((x+46)-x)/3)*2)+((x+97)-(x+46))

                 Equal= 81.66 minutes

Then, we take her total time – her total rest time to find her total driving time

                 677.27 – 81.66 = 595.61 minutes

                 Required percentage = 595.61/677.27 * 100 = 87.9%

So, the percentage that she is driving compared to the whole trip is 87.9%

AP Statistic

We has jump another big step in Math. This year in Math essential, I’m taking a college course, AP Statistic, which is a very challenging and involve a very high critical thinking skill. Not like other math we are doing, AP stat is quite fun, it is more to thinking about all world data rather than calculating the math like algebra. Moreover, I personally think that AP stat course will be more applicable to me in everyday life and in my further work. AP Stat is a lot of looking a bunch of data from whatever you want to investigate and analyse the association of those data. For example, I can collect data of people from various level of education and their income, then I can uses these data to analyse the correlation and the association between these two variables. The two main textbooks that we used to learn the materials are The Practice of Statistics and the Barron AP statistic test book. However, as we learning the concept, we realize that it is not enough, therefore, we uses many more online resource such as Khan academy, Edx course video and many others worksheet out there. So far, we finished four chapter:

  1. Chapter 1: Exploring Data
  2. Chapter 2: The normal Distribution
  3. Chapter 3: Examining Relationship
  4. Chapter 4: More on Two-Variable Data

Out of all these four chapter, my most favorite is the examining relationship between the explanatory variable (independent variable) and the response variable (dependent variable) to determine the correlation, form, strength, and the observation association. But the most exciting part of that chapter is finding the least square regression line, which is the line that predicted a response variable at a given response variable. This course will be one of the course that I will put a lot of effort in order to succeed in the AP test, but especially understand the idea behind those data.
