Forest Ecology Description

  • Ecology
Exploration Name: Forest Ecology

Exploration Dates: Oct 7, 2013 – Nov 19, 2013

Number of students: 12

Essential Questions:

(1) What is an ecosystem?

(2) What is a natural resource?

Description:  An ecosystem is the living things and the non-living things connecting with each other. The one example is algae. Algae take the sunlight for food and fish eat algae and then people eat fish. This is one connection. In Ecosystems class we had a journey book to take notes or write keywords that we don’t know what that word means. In Ecology class the first topic that we learned was tropical forest. We did not just learn only tropical forests but we also learned a lot of kinds of forests like conifers and others. A tropical forest is the forest that has rain a lot all year. We also learned about ecological relationships. Ecological relationships mean that one organism and another organism connect with each other. Ecological relationships are divided in five parts. They are parasitism, commensalism, predator-prey, mutualism and competition. Our Ecology group went to Mondulkiri province to study there. We spent six days at Mondolkiri. We met a lot of people like Bunong people. On Saturday we came back to our school and we shared what we learned.

Documentary Description

Exploration Name: Documentary

Exploration Dates: November 20 – January 17

Number of students: 12

Description: The first day of our class was very exciting because we heard from the teacher that we were going on a trip to Siem Reap for four days. It was just one week away. But we had to write our thoughts about why we would go to Siem Reap. Before we went on a trip we had to learn about shots and how to use a camera because to make a documentary we have to film. Some of the documentaries were about the sand business, rice farm and waterways in Siem Reap. The last day of the trip we rode a boat to see the waterways and even the floating village. It was a fun trip but we learned a lot too! Our goal was to make our own documentary about the waterways. At the end of our Exploration we made it, so now we have our own documentary.

Food Systems Description

  • Exploration Name: Food Systems
  • Exploration Dates: March 10 – May 2
  • Number of Students: 15

A food system is the cyclical process of growing, transforming, packaging, transporting, cooking, eating, and recycling food. Sometimes we can skip some of these steps. For example if we eat a mango that grows from a tree at our house we are skipping packaging, transporting, cooking, and transforming. This is an example of a local food system. An example of a global food system is chips that have ingredients from different parts of the world and are packaged, transformed and transported all over the world.

In our class we learned the difference between all three kinds of soil. They are sand, silt and clay. We started to grow the seeds. The seeds have grew, but we have not taken its to grow in our raised beds yet. In one day we have to give the water to the plants 3 – 4 times. We learned the six steps to grow the seeds, from laying the toilet paper to moving them in the tray. We have learned the part of the seeds. There are seed coat, embryo and cotyledons. We learned about the fruits and vegetables. We also learned about global and local food systems. Global is the food that is all around the world. Local is the food that is near. Ex: If we are Cambodian and buy the food in Cambodia that food is the local because it is near where we live. Ex: If we are Cambodian and buy the food from Malaysia that food is the global because it is far away from where we live. Also, we learn about the pros and the cons about local and global food systems.

We took four trips to learn about Food Systems. The first trip we went on Organic farm. The owner shown us how to grow the seeds. In his farm there are ten different typesof seeds: lettuce, fruit plants and herbs. Also, he told us that insects and the weeds destroy his farm. Weeds are the things that you don’t want. EX: In the farm have the grass that grows, the weeds is the grass because the farmer doesn’t want that to grow in their farm. New technology is that they cover the soil by the plastic because when we put the compost and the water will not go away. Compost is made out of the animals poo mixed with soil and rice husks. The second trip we went to Natural garden store. In that shop sell vegetables, snacks, wine and ingredients. The owner had taught us how to find where the food came from. The owner said that some of his fruits, vegetable and cookies are bought from France, America, Thailand, North America, Singapore, Germany and local. He has own farm in Kampong Speu and at Kampong Som. The third trip we went to University Agriculture. In there we learned about hydroponics. The guide told us that hydroponic is the new technology in Cambodia. Hydroponics means growing on the water. At there we saw lots of lettuce that grows on the water. The last trip we went to Rice Mill. We learned about the different rice in Cambodia. Also, we learned the difference between brown rice and white rice and how both of this rice is good for us.

Water Description

Exploration Name: Liger Water System

Exploration Dates: August 12 – September 26

Number of Students: 12

Description: In our water group we learned about the pH of water. The full words of pH is Percent Hydrogen. That is the kind of scale that people use to measure the acids and bases. The scale of pH is 0-14. From 0-7 is acidic, 7-14 is basic and 7 is neutral. The hydrogen (H+) is acid and hydroxide (OH-) is base. When we learned about pH we did the experiment with 13 liquid things. For ex: the coca-cola and pond water. The coca-cola was 2.0 so it means acidic. If we drink it a lot like every day we would get sick but if we drink in 1 week only 1 it will be good. The pond was 10.0 so it means basic and if it has a lot of basic like this it also not good for our health either. So we can eat or drink only higher than 7 to 9 or lower than 7 to 5, so it not really have many bases or acids. In this class we also studied about algae. Algae is the kind of plants that live in water and it uses the sun as it food. When this plant lives in water it will make water become basic. We studied our own pond at Liger to learn about this. One other thing that we learned was the water cycle. We learned when the sun rises then it does the evaporation with water. When water goes up it is not yet become the clouds but when the temperature is cool then it makes condensation so it becomes the cloud. When the cloud in the sky catches the cool temperature it will become the rain again. To learn about water we went on the trip to RDI. RDI is the place that makes the water filters to sell. One thing that we learned from there is why they made this RDI place because they saw that some people here don’t have the clean water to drink so they can buy it to get the filter and clean for them. Another reason is when they sell the water filter they sell as cheaply as they can to help the people in Cambodia.

Vapac Description

Exploration Name: VaPAC

Exploration Dates: Jan 20 to Mar 7

Number of students: 12 students

Description:

My group name is VaPAC. It stands for Visual and Performing Arts Cambodia. Our group areas are trip, sign language and mask-making. First I want to talk about the trip. Our group trip was going to Kampot Province. We went there to learn about the Cambodian arts and the disabled people. When we went there we knew that the disabled people can communicate by using sign language. Sign language is so important for the disabled people. We also learned some sign language too. The disabled people can do arts too. They do it by using movement. The next area is mask-making. Our group made the own mask. The mask is made by the paper. It took a lot of time to make one mask. When we finished doing the mask-making we designed what it will look like. The design can be used for performing. It also can be used for sale and hang it on the wall. Our goal was to make the story and do it by using the movement. When we do the movement we can’t say anything.
