Looking back on Rainforests!

Who remembers each of the topics we've seen in our Rainforests project?

Recycling Project!

During the last few weeks we've been working with recycling and its importance for saving the planet! We left boxes to recycle plastics and paper in every classroom, and today we went to look for them. A lot of children became comprimised with our project and helped us collect papers and plastics! They will be recycled, thus causing less contamination and helping the planet!!!

Congratulations Fourth Form :)

What happens to what we recycle?

We can help our planet by recycling! Let's see what happens with the things we have recycled!

Reduce, Reuse, Recycle!

El paso a paso de las historietas piratas digitales...

En este proyecto comenzamos leyendo varios cuentos de piratas del libro "Garfios". Luego, nos dividimos en grupos y observamos muchas historietas para tener en cuenta los detalles. Así fue como compartimos las características de las historietas: sus similitudes y diferencias.
Más tarde escribimos cuentos y posteriormente los transformamos en diálogos. Siempre pensando en que deberíamos hacer una historieta.
Una vez terminadas las historias y los diálogos de piratas, realizamos la historieta en papel, en las notebooks y con los ipads.
Utilizamos una aplicación llamada "Comic Maker" y una página de diseño de historietas bajo el siguiente link "www.chogger.com"
Un ejemplo del trabajo realizado con la aplicación Comic Maker:

Rip van Winkle

Rip Van Winkle

Rip Van Winkle was a lazy boy. He was so lazy that he slept the whole day.

One day, Rip Van Winkle, tired of his mother insisting on him getting a job, ran up a mountain with his best friend, his dog and his gun. He reached the top, crossed a stream, went to a spot where nobody ever came and sat down panting. He had never had so much exercise in all his life.

He was just getting back his breath, when he heard someone call his name. "Strange, nobody ever comes here and surely no one that I know," thought Rip Van Winkle. He turned to see a funny looking man carrying a big barrel. The funny looking man said, "Please help me carry this barrel to my friends a little below the stream."

Rip Van Winkle had climbed so far up the mountain to avoid work. Here was a man asking for help. He first decided to refuse but then thought, "Let's help the poor chap, then I can come and rest." So, he and the funny looking man walked down to a cave in the mountain, below the stream. There Rip Van Winkle saw many other funny looking men, all of them were playing the game of bowling. They ignored him. As soon as the barrel was placed in the ground, the men pulled out glasses, dipped it into the barrel and drank. It was wine.

Rip Van Winkle too dipped a glass in the barrel and drank the wine. It tasted good. He thought he should have one more glass, then another and another, until he found the room swinging in front of him. Rip Van Winkle went to sleep.

When he awoke, he saw that all the funny looking men had gone. He called out to his dog but there was no response. He could not believe he had slept the whole day and night. He got up, his joints ached. He picked up his gun. Instead of the clean well oiled piece, he found the barrel rusted and the lock falling off. He threw it away.

As he started trudging back home, he saw the village down below, which seemed somehow changed. When he entered the village he saw new faces; all of them looked at him and rubbed their chins. Seeing them do this, Rip Van Winkle did the same. To his astonishment he found he had grown a foot long beard overnight.

Rip Van Winkle was puzzled; he believed that he knew most of the village folks well but there did not seem to be anyone he knew around. This was the same village, where he could see the mountains and the streams. The children made fun of him, running behind him, pulling his beard.

Rip Van Winkle stopped by a place where there had been a school and asked the crowd that had gathered, "Where is Schooner, the school master?" Somebody said, "Oh! Schooner, he went to war in sixty three and never came back." "And Van Dammel?" asked Rip Van Winkle. "He died eighteen years back," said another voice in the crowd. Rip Van Winkle thought he was going mad. "Had he slept all these years on the mountain?"

Finally Rip Van Winkle asked, "Does any one here remember Rip Van Winkle?" A very old woman said, "Yes, he was my lazy son. He went up the mountains twenty one years back but never returned. His dog came back without him."

Rip Van Winkle was overjoyed. He said, "Mother, it is me Rip Van Winkle. Don't you recognize me?" "Oh! My son. It is really you. Where have you been all this while?" Mother and son hugged each other.

Rip Van Winkle had indeed slept for twenty one years.

What is Deforestation?

What can YOU do at school?

Deforestation: impact on Rainforests

What is Deforestation?

Deforestation refers to the cutting, clearing, and removal of rainforest or related ecosystems into less bio-diverse ecosystems such as pasture, cropland, or plantations. 

What are the causes of deforestation?
I.   Logging
II.  Mining
III. Oil and gas extraction
IV. Cattle ranching
V.  Agriculture: Cash crops
VI. Local, National, and International factors: development, land titles, government subsidies to attract corporations into developing countries, trade agreements, civil wars, debt, lack of resources, and lack of law enforcement.



Deforestation in Borneo.
Largest rainforests worldwide listed in descending order (from largest to smallest).

1. Amazon basin of South America
2. Congo river basin of Central Africa
3. South East Asia
4. New Guinea
5. Madagascar

Facts:

• Did you know that tropical rainforests, which cover 6-7% of the earth's surface, contain over half of all the plant and animal species in the world!
• Did you know that 57% of all rainforests remaining are located in the Neotropics, with 30% located in Brazil!

Overview of deforestation around the world:
Between 1960 and 1990, most of the deforestation occurred globally, with an increasing trend every decade.

• Brazil has the highest annual rate of deforestation today.
• Atlantic coast of Brazil has lost 90-95% of its rainforest.
• Central America has 50% of its rainforests.
• South America has 70% of its rainforests. 
• The Philippines have lost 90% of its rainforests!
• Madagascar has lost 95% of its rainforests!
• El Salvador has lost 70-85% of its rainforest due to heavy bombing during the civil war 1984-1985.
• Sumatra has 15% of its rainforests left.
• Only 6% of Central Africa's forests are protected by law.

Destructive logging in Malaysia.
Statistics on Global Rates of Rainforest Destruction:
2.4 acres (1 hectare) per second: equivalent to two football fields
149 acres (60 hectares) per minute
214,000 acres (86,000 hectares) per day: an area larger than New York City
78 million acres (31 million hectares) per year: an area larger than Poland
On average, 137 species become extinct everyday; or 50,000 each year!

*If the current rate of deforestation continues, the world's rain forests will vanish within 100 years- causing unknown effects on global climate and eliminating the majority of plant and animal species on the planet*



Small-scale deforestation in the Amazon.
What are the consequences of deforestation?

Environmental:

1. Extinctions (loss of biodiversity of microbes (bacteria), plants, insects, animals, indigenous peoples, etc. 
2. Habitat fragmentation.  This disturbs the animals' habitat and may force them to enter habitats which are already occupied.  This can pose many problems such as territorial conflicts, homelessness (loss of habitat), lack of food availability, migration disturbances, etc.
3. Soil erosion occurs when trees and plants are removed; the rain water washes the nutrients in the top soil away. 
4. Changes in watershed geomorphology.
5. Desertification (dry, hot, arid conditions).
6. Edge effects can change microclimates (small climates) which affect endemic species (native species which can only live in specific environmental and habitat conditions).
7. Climate change (more carbon dioxide is released into the atmosphere, thus increasing the effects of global warming).
8. Pollution (ground, water and air pollution from oil extraction and mining chemicals).

Deforestation for palm oil production in Borneo.
Social impacts:

1. Loss of culture (indigenous peoples subsistence living in the rainforest).  People who live in the rainforest depend on the natural environment for food, shelter, materials for cooking, clothing, etc.  If the forest is cut down or if their environment becomes polluted from oil extraction and mining, they are forced to move or risk starvation and sickness.   
2. Displacement of people (loss of farmland, forest resources, etc).
3. Social conflicts and struggles over land and natural resources.
4. Conflicts over racial and ethnic rights.
5. Poisoning from oil and mining waste.
6. Economic uncertainty (price fluctuations and high interest rates on outstanding international loans with The World Bank and International Monetary Fund. 

Oil Palm Estate and Rainforest in Malaysian Borneo.
What can we do to STOP or at least lessen the amount of deforestation and conserve our own use of natural resources such as wood, oil and gas, electricity, minerals and elements, and water?  Brainstorm...here's a start:

• Always use both sides of paper when writing, drawing, photo-copying, faxing, etc.
• Recycle paper, cans, glass, and plastic.
• Read the newspaper on-line.
• Buy paper products made from recycled paper: notebook paper, paper towels, toilet paper, books, etc.
• Use pencils until they are stubs!  Think of pencils as gold (you'll never lose them if you do).
• Encourage your parents, relatives, and friends to buy furniture and wood that is Certified.  That means the wood was legally cut-down.
• If you buy a product and you notice they use wood chips to package it, write to the company and suggest they use another packaging material.
• Trees get cut down for cattle to graze.  Instead of eating meat, think of eating other sources of protein such as fish, soy, beans, whole-wheat, and nuts. 
• Buy organic fruits and vegetables.  That means there are no insecticides or pesticides (poisonous chemicals) sprayed on the food.  If these chemicals kill insects and pests that try and eat the vegetables, think about how harmful they can be to you and the environment.   
• Instead of buying gold or diamonds, which are mined and cause environmental damage, consider jewelry that is made from materials that are not mined...such as glass.
• Encourage your parents, relatives, and friends to drive fuel efficient cars that get good gas mileage.  Hybrid and bio-diesel cars get great mileage and use less or no gasoline. 
• Even better, whenever possible, walk, bike, carpool or use mass transit (bus or train).
• Save electricity by turning off lights, t.v., radio, computer, etc when you are not using them.
• Save water by NOT taking baths; instead take quick showers (turning off the water while you soap up) and then turning it back on to rinse quickly.
• While washing your hands and brushing your teeth, turn off the water.  You'll save gallons if you do. 
• When washing the dishes or your parent's car, turn off the water while washing it with soap.  Rinse quickly after washing. 
• Hmmm, can you think of other ways to conserve wood, oil and gas, electricity, minerals and elements, and water, etc...?

Maori Haka

The Haka is a traditional war chant, dance or challenge from the Maori people of New Zealand. It is a posture dance performed by a group, with vigorous movements and stamping of the feet with rythmically shouted accompaniment.

They can be performed for many reasons: for amusement (fun), as a welcome to a guest, or to acknowledge great achievements, occasions or funerals

The New Zealand rugby team, the All Blacks, perform a haka before their matches.

People of the rainforest

PEOPLE OF THE RAINFOREST

We often overlook the millions of people that live in the rain forests.  Did you know that there are about 50,000,000 tribal people living in world's rainforests?  These people depend on the forests for their food and shelter.  As we cut more and more trees and destroy more and more of the forests, we are also killing people.  Many native tribes have been exterminated already because their governments failed to protect them from logging companies, the mining companies and the slash and burn farmers. Here is some more information about three of the larger and more well-known tribes:
	The Pygmies This Pygmy woman is food outside her hut, with her baby cradled on her back. Mbuti and Baka Pygmies live in the rainforests of Central Africa.  Traditionally they live by hunting and gathering food.
	The Huli The Huli are one of the many tribes that live in the remote highland forests of Papua New Guniea.  They live by hunting, gathering plants and growing crops.  Men and women live seperately, in large group houses.  The men decorate their bodies with colored clay and wear elaborate headdresses for ceremonies.
	The Yanomami One of the largest groups of Amerindian people in South America is the Yanomami.  Their village life is centered around the yano, or communal house.  The yano is a large, circular building constructed of vine and leaf thatch, which has a living space in the middle.  This picture shows Yanomami men eating a meal.

Why are rainforests important?

WHY ARE RAINFORESTS IMPORTANT?

Rainforests are important to the global ecosystem. Rainforests:

• provide a home to many plants and animals;
• help stabilize the world's climate;
• protect against flood, drought, and erosion;
• are a source for medicines and foods;
• support tribal people; and
• are an interesting, beautiful place to visit

The air we breathe comes from trees, and most of the World's trees live in Rainforests!

Rainforests help stabilize the world’s climate by absorbing carbon dioxide from the atmosphere. Excess carbon dioxide in the atmosphere is believed to contribute to climate change through global warming. Therefore rainforests have an important role in addressing global warming. 

Rainforests also affect local weather conditions by creating rainfall and moderating temperatures. 

Rainforests are home to a large number of the world’s plant and animals species, including many endangered species. As forests are cut down, many species are doomed to extinction. Some rainforest species can only survive in their natural habitat. Zoos cannot save all animals.

Why are Rainforests important?

Rainforests are often called the "lungs of the planet" for their role in absorbing carbon dioxide and producing oxygen. All animals depend on oxygen for survival! Rainforests also stabilize climate, give house to incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet. 

Rainforests:

• help stabilize the world’s climate;
• provide a home to many plants and animals;
• maintain the water cycle
• protect against flood, drought, and erosion;
• are a source for medicines and foods;
• support tribal people; and
• are an interesting place to visit!

Rainforests Project: What is a Rainforest?

What is a Rainforest?

A rainforest is a hot, thick jungle that gets a lot of rain. A large number of plants and animals live there.
Most rainforests are located around the middle of the Earth, near the Equator. They help to clean the air that we breathe!

And here is another video of the amazing tropical rainforest!

Some rare Rainforest plants...

As we know, Rainforests have many layers, and in these layers, we can see different plants.

In the different layers we can find a lot of plants. Some of them are even carnivorous!

Why are Rainforests important?

Rainforests are really important! We all need air to breathe, and this air comes from the trees! As we know, Rainforests are the most important "air producers" in the planet! So we must take care of them.

Do you know how many trees only one person needs to breathe? The answer is: a lot of trees!

So when we ask "why are Rainforests important?"... what will you answer?

September 3: Dictation

He was an old man who fished alone in a skiff in the Gulf Stream and he had gone eighty-four days now without taking a fish. In the first forty days a boy had been with him. But after forty days without a fish the boy’s parents had told him to go to another boat which caught three good fish the first week. It made the boy sad to see the old man come in each day with his skiff.
