Food Systems Description

Exploration 6

  • 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.

Ecology Description

Exploration Name: Forest Ecology

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

Number of students: 12

Essential Questions: (1) What is an ecosystem mean? (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, commercialism, 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 and they played their music to us.   Also they teach us how to play the song too.

On Saturday we came back to our school and we shared what we learned.

Microfinance Description

Exploration Name: Social Business

Exploration Dates: Nov 20 – Dec 17

Number of Students: 12

Essential Questions: How does social business alleviate poverty? What is the role of women in microcredit systems?

In Social Business class we learned about microfinance, Tong Tin and saving money. Microfinance is the bank that is for the poor people to loan the money. We learned about microfinance in Cambodia. We went on a trip to interview community people about microfinance. They microfinance is good for them because they can loan the money to make the business. We learned about Tong Tin. Tong Tin is very common at Cambodia. At Cambodia people like to play Tong Tin because they can win money on it but it might take a long time like maybe one year or more. Tong Tin can be bad and can be good. The bad thing about that game is we need to pay a lot of interest. The good thing is we can win the money. One day we learned how to play Tong Tin. We also learned about saving money. We went to Phnom Penh to visit the Kok Tha. Kok Tha is the manager of a savings group. We had a lot of trips and it was very helpful for our team.

Here is our blog that our group make to share to other people in the world.

Renewable Energy Description

Exploration Name: Renewable Energy in Cambodia (Poo)

Exploration Dates: Oct 7 to Nov 19

Number of students: 13 students

Essential Questions:

1. Are biogas and solar energy sources practical and cost effective in Cambodia?

2. What are the benefits and drawbacks to using biogas and solar energy in Cambodia?

Description:

In our Exploration class we had three things to work on. The first area was the solar system. The solar system is a resource that can create the energy from the sun. Solar has four types: solar panel, solar cooker, solar water heater and solar lamp. A solar panel is the solar thing that creates the energy to run the electricity. A solar cooker is the solar thing that creates the energy for cooking. A solar water heater is the solar thing the creates the energy to turn the normal water to the hot water. A solar lamp is the solar thing that creates the energy to light the house if that house doesn’t have the electricity. The next thing that we learned about was the biodigester. A biodigester is a natural system that can create biogas by using poo from the animals. Cow poo is the best. It has a lot of benefits. Example: (1) saving the money, (2) healthier than using firewood, (3) save a tree. The last thing that we learned was about hydroelectricity. Hydroelectricity is a thing that creates the energy by using water. It usually is built over the river. The biggest dam in the world is in China. Our goal was to make Cambodians know that all of these things can create energy. Also we wanted them to use these three things because they are good and can save a lot of money. We also had a trip too. The trip was to go to Kampong Speu. Our target was to install two biodigesters. We install them in Camkids and the orphanage called HAP because we wanted to make them easy instead of using the firewood. Both of the biodigesters cost $1100. When we went to to Kampong Speu we also taught some students too. We also slept at Kampong Speu too. We had good days when we were in Kampong Speu province.
