Balanced chemical equation

On the 14th December, me and Samnang Hor taught a junior STEM class about balancing chemical equation. So we come up with some fun activities for them to practice like using the simulation and also Kahoot. We start off by trying to understand what they have learned than explain them why do we need to balanced chemical equation. We need to balance the chemical equation because the mass of the atom can’t be created nor destroyed according to the law of conservation of mass.

+  The plus symbol connects the first substances and the final substance. (seperate two reactants or products)

→  Identify the chemical reactions into products. Or chemical change or produce.

Reactants are the starting materials in chemical reaction. The substance that go through changes during the reaction. The substances on the left side of the arrow are called reactants.

The substances on the right side of the arrow are called products.

Can’t write # 1 as the coefficients but just put a blank there. Example: O2

Animal and pet ownership responsibility workshop

Today, on the 13th December our teacher brought a host from Animal Rescue Cambodia and FOUR PAWS for a workshop that is about animal and pet ownership responsibility. These two organizations are trying to help abundant pet or wild animals but especially cats and dogs from being a stray. There are 5 basics need for pets: Suitable diet, Suitable environment, Protection from pain, injury & disease, the ability to express normal behaviors and protection from fear & distress. What are all of these 5 basics needs mean? Let start with suitable diet, pets should have a healthy food and fresh clean water. For a suitable environment, pets should have a proper shelter.  Protection from pain, injury & disease, the owner should bring the pets to the vet to give the injection and protect them from spreading any disease. Ability to express normal behaviors, once in a while the owner should walk the pet out and let them get a little bit of exercise. Lastly protection from fear & distress, the owners should give attention, love, and care as much as possible. After learning about these 5 basic needs for pets, we moved on to answering some question such as where are these street animal come from, What problem do they face, what problem does these street animal bring to the community, what action or solution can we take. Then we discuss dog and cat meat trade which these animal going through pain before being killed and eaten. The human who’s eat dog or cat have a high risk of getting the disease from the animal. Even Though there is a high population of dogs and cats but we shouldn’t eat them because they also have a life to live. If you saw an abundant animal that is sick please take action like bring some food and clean water, and possibly call any animal organization for help.

Chemistry round 2

We been learning and using the periodic table for awhile now. There are many topics in chemistry we been covered. This round we focus more on drawing lewis dot structure that related to elements, atoms, compounds. Than we learn about the octet rules and formal charge. Element that are on or under the 3rd row in periodic Table can hold up to 10 electrons breaking the octet rules.

Lewis dot structure → shows bonding between atoms

Example:                 

Li ⇒  is Lithium and it have 1 electrons

Octet rules atom wants to have eight valence electrons in its outermost electron shell to become like a noble gas so, it combine with other atom and share electrons.

Example:

H2O ⇒ is an chemical formula stand for water

H: 1 electrons & O: 6 electrons = 8 electrons

*This sign    stand for 2 electrons*

Formal charge ⇒ the charge that are assigned to an atom, assuming that electrons in bonds are shared equally between atoms.

Equatione: (# valence electrons) – (# valence electrons in bonded atom) = 0

Example:

H = 1 e        1 – 1 = 0 *True*

O = 6 e        6 – 6 = 0 *True*

*Because it share electrons that why we count only 1 of the electrons that they are holding to.*

Frisbee League — Girls Power

On the 6th December, we had visited the girl down at kampong speu after we got an approval from the government. This time our plan was to go there to just throw frisbee disc around and introduce them to what is frisbee and who are we. The first school we visited was Chabok high school both grade 10 and 11 and we only 5 mins since they are having an exam. When I look back to this school, I still think this is crazy that my whole group did this. What we did was, presents to the whole classroom about our project alone with boys sitting there which wasn’t our target. But anyways we are trying to promote girls into playing Frisbee and as my observation girls didn’t have any courage to raise their hand up to join and play this Frisbee. Also it might because that they didn’t get to play with Frisbee like other schools that we visited. Sadly the class I presented to, there was no one wanted to play Frisbee. Like other presenter they didn’t get it to and some got about 10 to 15 students. But at same times we got around 70 girls for the whole school which is good for the training and eliminating for the league. Soukhaphaly high school, the girls there was really interacting with us and they showed a lot of excitement.

We even tell every schools that next week we will come back and do a pitch to them. Also try to get their name by then so that we can prepare on how many people are going to show up for the training. Over this Christmas break, Some Kampong Speu students and me will be going to every school on Sunday to get them familiar with Frisbee. Then in January they will start the real training.

Girl interest in playing frisbee         Total: 265 girls

  • Chabok High School 
    • Grade 10 & 11 #70 students
  • Kampong Speu High School
    • Grade 10 & 11 #38 students
  • Sokhaphally High School
    • Grade 10 #29 student
    • Grade 11 #36 student

Geometry

We were learning about geometry and most specifically about transformation, Congruence, Similarity, and Right triangle & trigonometry. So we are using Khan Academy to help our guild through this topic because the in the textbook it doesn’t demonstrate and give examples much. For each level, we reach we got 4 points and there is 6 level which is mastering it but the teacher expected us to get to level 5 and we will have 20 points. However, if we have any questions we can screenshot it, and then we will go over it in class together. By doing this it allows us to go at our own pass and not rushing through to gets point but actually understanding it. Moreover, it gives students the opportunities to take more responsibility and show that they use their time wisely.  

Transformation

  • Rigid: maintain and produce congruent shape
    • Translation: vertical and horizontal shifts
    • Rotation: it’s rotate in a certain degree.

270 / -90 degree = x,y   y,-x

-270 / 90 degree = x,y  -y,x

180/-180 degree = x,y  -x,-y

  • Reflection: line of reflection and it’s a mirrored image

 

  • Dilation: It have the similar shape but different size and it’s scaleable and it’s angle is the same.

Congruence – equal size and shape

Similarity – same shape in term of ratio

Right triangle & trigonometry

Sin = Opposite over Hypotenuse

Cos = Adjacent over hypotenuse

Tan = Opposite over Adjacent

Law of sin = > sin (a) over a = sin (b) over b = sin (c) over c

  • If you have 2 angle and 1 length use it to find another length
  • If you have 1 angle and 2 length use it to find another angle

Law of cos

=> a² = b²+c² * – 2bc cos(o)

=> b² = a²+c² * – 2ac cos(o)

=> c² = a²+b² * – 2ab cos(o)

  • If you have 2 lengths and an angles use it to find another length
  • If you have 3 lengths use it to find an angles
  • a, b, c  representing the lengths

Critical Teen Issues បញ្ហារបស់យុវវ័យ 

On Monday the 12th of November 2018, we did a Critical teen issues workshop on the topic of healthy relationship. We divided the Senior into 2 teams and junior into 6 teams and the presentation was in Khmer and it based on the survey. We know that these topic were not typically been talk about so we want to raise an awareness and ideas to have a healthier relationships. Healthy relation does not only apply to boyfriend/girlfriend but it apply to friendship, boyfriend/girlfriend, family and society. The presentation went very well as it was plan out but I can improve by taking more control on the student. Down there’s like a outline of the presentation both English and Khmer.

Critical Teen Issue

In the Critical teen issue we have multiple topics, for round 1 we focused on the healthy relationship. We have been creating questions related to the relationship between Partners, Peers, Family, Social. We translated all the questions, turn it into google form and sent it to all Liger student. While we are doing that, We also create a plan for the workshop. Based on the answers we got, we will focus more deeply into the relationship that isn’t healthy. We will also implement this workshop into garment schools but not running it yourself. 75% of the workshop mostly are activities this way they will get the point more easily and then we will show them the consent video that we create. In this project I just learn that “No.” Is a complete sentence. 

Example:   Question Draft

Liger Literacy Leadership Team

This year in my English literacy it’s unique than other classes and it’s called the Liger Literacy Leadership Team. We are becoming a leader and independence learner. So for this round, we are focusing on Literature is Everywhere, which we can use children book to learn about literary devices, different culture, and new vocab. Our teacher was inspired by the book called The Rent Collector so she decided to have the Liger Literacy Leadership Team and let us read the book. Moreover, we did a group discussion, create poems and interview the author of the rent collector. This is one of my poem inspired by Sang Ly determination to find Sopeap which is her teacher. 

Title: Dedication to my beloved teacher

I’ve been solving puzzles, running into people  and here I am…beside her.

She once told me that this house is her favorite place.

I don’t want to say goodbye to this person….

The person who has been helping everyone and disguising her own identity.

Just like a turtle hiding under its shell.

Instead of talking, we both tilted  our heads,

looking at the shadow of the rain in silence and took a deep breath of fresh air.

At that moment I can feel the tension and pain between us.

But we can’t have any rainbow without any rain.

The rain is both a fading memory and a distant promise.

Goodbye goodbye my beloved teacher.

Frisbee League – Trip to Kamong Spue

One of my long-term explorations is called Frisbee League in Cambodia. In this exploration, we are creating the first Cambodian Women Frisbee League to empower women in sport for rural kampong speu girls and then if this project work we would open up to all girls in Cambodia. As one of kampong speu girls, I am so excited and proud to be in this group and I can’t imagine when I’m teaching them to play frisbee. Moreover, We have a lot of things that needed to be done before our Pchum Ben break, so after the break, we will go and appraise the government about our project. This project really needs the government helps because in order this to be done we need their permission to work with those high school girls. Since I know a lot about Kampong Speu, I did some research and ask my relatives, do they know any high school around Chan Thnal high school. Chan Thnal high school is one the main school that we wanted to collaborate with. Then I lead a team to Kampong speu and visits the five school that are on my list. I need to track down the distance and time it took to arrive at each school. We even go and talk to the principles of our project and they really excited to work with us but they need the permission from the government. Nevertheless, our exploration already prepares all of those so that when the students come back from their big break we are able to talk to them and before that, we convince the government to help with our project.

Math round 1 of 2018-2019

For this round we were working on SAT prep. So basically, we continued focus on SAT but this time in class we wrote down what we haven’t learn and within this year our teacher will teach us a few of those topic. This round we learn about imaginary number, complex number, functions and quadratic. For function and quadratic we learn and practice in Khan Academy algebra 1.

Imaginary number ⇒ i

i = √-1

i^2= -1  

i^3= -i

i^4= 1

Complex number ⇒ a +bi

a = real number

bi = real number times by imaginary number

Example: 5+2i

* imaginary function

a/bia/bi*bi/biai/b-ai/b

Example: 5/3i  ⇒ 5/3i  * 3i/3i ⇒ = – 15i/9

*multiplying by the conjugationa doesn’t have to be the same

a/(b + i )⇒ (a/(b + i)) × ((b – i) ÷ (b – i)) ⇒ (a – bi) ÷ (a – bi²)  (± a – bi) ÷ (b)

Example:

4 ÷ (9 + i) ⇒ (4 ÷ (9 + i)) × ((9 – i) ÷ (9 – i))  ⇒ ((36 – 7i) ÷ (81 – i²)) ⇒ ((36 – 7i) / 82)
