Chemistry? Lab? FOOD!!!!

We are learning about theoretical yield and actual yield. We are using those yield to calculate the percentage yield. To elaborate and to get a better understanding of what it means and what the scientists are using those for, our generous chemistry’s teacher decided to have a SMORE LAB!! 

In order to make s’more we need, crackers, chocolate and of course marshmallows. 

To find the percentage yield, we need to take the actual yield divided by theoretical yield and time it by 100. 

  1. Calculate the theoretical yield by measure the weight all of the substance that you use to make smore
  2. Roast your marshmallows and chocolate on the Bunsen burner
  3. Make your smore by putting the marshmallows and the chocolate between the crackers
  4. Weigh your final product
  5. Find the percentage yield


Nutrition Exploration, we went off to Prey Veng Province to do a workshop with villagers about nutrition. We partnered with World Renew Team in Prey Veng Province. 

In the workshop, we shared about

    • What is nutrition?
    • 3 types of food
    • Lack of nutrition
    • Nutrition
      • Vitamin A
      • Iron
      • Iodine
    • Hygiene 
    • Breastfeeding
    • Baby food
    • A short educated video about nutrition that we made with World Renew Team


The whole workshop was in Khmer. It’s kind of challenging with some technical words, but we get through it. 

My perspective was that we are only do the talking part and they listen in peace. But it turns out that they were asking a really good questions with their enthusiasm. 

In addition, we are having a lot of fun!


Gender equity is one of the biggest issues in the global, we must take the action. My exploration named Change Gender Equity and Change stands for Creating Humanitarian Awareness for the Nesassarary of Gender Equity. Our mission is to raise awareness about global gender issues with a focus on Cambodian society. In order to affect positive change, we must examine the past to transform the future. Through communication, passion, and risk-taking we will investigate various aspects of gender discrimination and inequalities by sharing stories, exchanging knowledge, and interacting with others to create a healthy and constructive dialogue about gender equity.

I learn about the difference between equality and equity. Equality is treating everyone the same. Equality is fairness and it only works when people need the same help. Equity is providing help in order to make them successful. Equity seems to be unfair, but it actually it tries to move everyone as close to the success as possible. But in society, everyone starts at different places and don’t have the same need so equity would be fit in this circumstance. My favorite part of the exploration is to learn about the stereotype. In the society, the stereotype is everywhere and anywhere. The stereotype is people perspective on someone or something. 

Over the past seven weeks, a group of twelve students and two facilitators at Liger Leadership Academy have investigated a variety of topics related to gender as part of an exploration entitled “Gender Equity.” As our final product, we decided to organize a gender summit to raise awareness and create the dialogue about these very important global issues. Our summit will take place over two days, January 27th and 28th and will be conducted in both English and Khmer. We have invited high school age students from around the country to attend this event. Stay tuned for our gallery of student work, photographs, and interviews from the summit.

In the Ecosystem Services and Climate Change Exploration, we worked with Song Saa Foundation to focus on three main areas: organic gardening, lightning prevention and protection and a fish population survey. We went to two different communities on Koh Rong which is located, offshore of Preah Sihanouk province, to do a workshop and conduct a fish population survey. The data will be analyzed to see which fish species are being depleted, according to the elders.  The workshop focused on safety from lightning since lightning is increasing with climate change. We also spent an afternoon building a fence at Sala Song Saa and prepared for an organic garden for Prek Svay community. Moreover, we distributed over a hundred water filters to the community at Prek Svay. Lastly, we snorkeled over coral reefs, through seagrass beds, and with bioluminescence. Thank you to Palm Beach Resort for providing us camping space, and providing us a night boat ride to swim with the bioluminescence.


This is a really brand new social study for me to do. I have an opportunity to work with International School Phnom Penh’s students (ISPP). We are planning for Phnom Penh Youth Film Festival (PPYFF) to make it happen. The goal of PPYFF is to promote creative storytelling and teamwork, help kids learn the many skills involved in filmmaking, and to plant the seeds that will grow into the future of the Cambodian film industry. So far we’ve done on making website, posting on social media and stick flyers around schools. The event will be happening on Friday, March 30th for the annual PPYFF event! More than three dozen student films will be premiered and celebrated at ISPP’s world-class Black Box Theatre. Watch the films, meet the filmmakers, and stay for the award ceremony! Awards will be given to the best picture, director, screenplay, cinematography, editing, and best actor. We hope to see you there! We hope that there’s a lot of people will join the PPYFF competition and we also hope that there’s a lot of audiences come and support the event and the filmmaker.

41 years ago Cambodia was occupied by the Khmer Rouge (KR). It was the most destructive period of time in Cambodia. Everyone’s life was threatened by killing, malnutrition, being overworked, starvation, and mainly the death from weapons such as guns, mines, bombs, artilleries, and helicopters. Most of the weapons were imported from the United States, China and Union of Soviet Socialist Republics, known as USSR. The Khmer Rouge traded agricultural products to get these weapons.

We visited three museums that are related to Khmer Rouge war: War Museum, Cambodia War Remnants Museum and Landmine Museum. The common things that all three museums have are the weapons that were used during the war, and all of those weapons were found around the museum areas and in the forest along Thai border. Those weapons are: guns, mines, bombs, tanks, and artilleries.

What I learned from the War Museum is that after the war, there were six million mines and eight million bombs left in Cambodia. Now, 80% of the mines were cleared but 1.2 million mines still remain. One connection is that those bombs were also a reason that the Khmer Rouge gain their power through propaganda because the Khmer Rouge soldiers told everyone that they need to fight back against the US because US was dropping bombs in our country.


In this exploration we are learning mostly about anemia. We found out that 25% of the world population and 43% of Cambodian women and 53% of Cambodian children are anemia. Anemia are caused by genetic, parasites and iron deficiency. Genetic is when you parents pass the DNA to you. Parasites is when the hookworm eat you red blood cells. Last but not least is iron deficiency is when you don’t have enough in your body. To solve the anemia problem is to eat healthy food and food that contain a lot of iron in it. The food that contain a lot of iron are beef, pork and green leafy vegetables. From age 19-50 years old they should contain 18 ml gram of iron per day and the pregnant women they should contain 27 ml of iron per day. Pregnant women should contain more iron than the others because when they give a birth to their kids they lost a lot of blood and the iron are in the blood. So it also mean that they also lost a lot of iron. We collaborated with Lucky Iron Fish Organization. This organization is making the fish that contain iron. They helps to distribute the iron fish to the villagers that can’t support the healthy food for their family. We also went to Siem Reap to do the presentation to the villagers about how important is iron in our body. We not only went to the village, we also went to one NGO called Future of Khmer Children. We help the Lucky Iron Fish to distribute the fish to all of the villagers that came and listen to our presentation.


In this Exploration, we hope that we can study different kind of spiritual and write a description about it including the history. Though, we want to see the real situation and interview Cambodian that they have seen spirits before. We want to go to the famous spirituals place that Cambodian people have been talking about it and they believe in that place. Also we want get as much information as possible, so we can help providing information to our LigerCast episode 4 (talking about spiritual). We have one silly goal, we want to meet one ghost if it possible.


Our goals are to make a Liger Yearbook and share it with people all around the world. To achieve these goals we need to work with the book printing companies and collaborate with each other to write the story of year four at Liger. We will include a lot of pictures and multimedia created by Liger students and staff. Most of all we will make Liger a model for educating people locally and globally.  



There are more than 700 temples in Cambodia, but the most visited temple is called Angkor Wat. In the past, the elders said “Angkor Wat is the paradise on Earth.” Angkor Wat is located in Siem Reap, Cambodia. Angkor means city and Wat means​ ព្រះវិហារ (Preah Vihear). There were five thousand workers who used rocks to build the structures.  They had to take 300 to 400 rocks  a day. Angkor Wat is the biggest temple in Cambodia. It took 35 years to complete. The highest point in the Angkor Wat is 65m (middle part), the length is 250 m and width is 12 m. Angkor Wat  faces test. One interesting thing about Angkor Wat is that it is built on water.. The space between the water and  Angkor Wat is 5 km, the length is 1250 m and the width is 200 m. Most of the rocks are having holds and it can’t carv to make the pictures on the wall. There are 1,532 pillars at Angkor Wat.

One day you should visit Angkor wat, learn about it and see how magnificent an achievement Angkor Wat is.
