Chemistry - Recycling of Metals

a.     What will happen to the world if there are no more metals?

            Metals play an important part in modern societies and have historically been linked with industrial development and improved living standards. Each metal has its especial uses and very important in our life.

For example:

-Copper and aluminium wire are used to carry electric current.

-Copper, aluminium and iron are used to make domestic utensils and factory equipment.

-Thin foils of aluminium are used for wrapping cigarettes, medicines, confectionery, etc.

-Aluminium is used for making angles, doors, pipes, etc. which are used in the construction of houses.

-Metals such as sodium, titanium, zirconium, etc. are used in generation of nuclear energy and in space science projects.

-Mercury is used in thermometers.

-Magnesium metal is used as a strong reducing agent to prepare other metals.

-Gold and silver metals are used to make jewellery.

-Thin foils of silver and gold are used to decorate sweets.

-Uranium metal is used to generate nuclear energy.

-Titanium metal is very hard, resistant to corrosion, light, has high melting point and is good conductor of heat and electricity. Because of its unique and useful properties titanium is sometimes called ‘the wonder metal’.

…

We can see so many uses of metals so without metals, it would be difficulty in making things that we are using. There will be no more domestic utensils, factory equipment, medicines, furniture, appliances, tools…

b.     Is it important to recycle metal?

Yes, it is.

c.      Thus what are the reasons to recycling metals? Isn’t it easier to obtain metals through its original from through extraction of metals?

    

Reasons to recycling metals:

-It is easy and cost-effective to recycle metal, and metal can be recycled continuously without losing its properties.

-When it is easy to do, human should recycle rather than to continually deplete the earth’s natural resources.

-It saves the Earth.

-It saves Energy. Recycling used materials reduces energy requirements in many manufacturing processes such as refining and mining. Recycling materials like aluminum and glass can greatly reduce the pressure on energy resources.

-It helps extend the life and usefulness of something that has already served its initial purpose by producing something that is useable.

-It saves Money. With the reduction in costs to re-manufacture used metal through recycling, there is even more money to be made across the board. This impact that metal recycling has, not only helps protect the environment and protects our natural resources for generations to come, but creates in the hundred thousands of jobs across the world.

Some of the effects Recycling of metals has on the environment.

- The environment is not a single thing - conservation of resources, energy, air and

water pollution, and psychological and political aspects are often competitive, and what may help in one area may be harmful in another

-As lot of debris is collected everyday for recycling, and so the recovery sites can become unhygienic. Abandoned dump sites can severely damage the surrounding environment. Harmful chemicals in the trash, can mix into water and soil. This can cause water and soil pollution and harm plants and fish in the streams and lakes.

-In addition to conserving energy resources, metals recycling also reduces mining and beneficiation activities that disturb ecosystems.  Though land used for the extraction of primary metals represents under 0.1% of Earth’s terrestrial surface, exploration and mining activity can affect surrounding ecosystems due to necessary infrastructure and by dispersing metal compounds into the environment.

d.     Think of reactive ways that we can also play a part in recycling metals?

For some metals you do not use anymore, we can modify it and create it to be another thing we can use. For example: if we don’t use the cans anymore, we can cut the cover, decorate the outside. Put in woodland and then planting by seed. Or the steel we can stick them and then bent it, create it to decorate.

Technology Task

1. What is MTV?

formerly an initialism of Music Television, is an American network based in New York City that launched on August 1, 1981. A cable and satellite television channel that broadcasts popular music and promotional music videos.

2. Effects of MTV on the youths of today?

-Keeps our knowledge fresh and up to date by providing us with the latest things that are happening around us.

-Allows us to represent ourselves to the rest of the world.

-Youths are in control and choose a media that they feel like compliant their mood.

-Youths in control of their viewing and the new waves of technology and more channels that appeal to every single possible music taste.

3. Effects of MTV on you - why do you like/dislike MTV?

- MTV help me to update the new music type, fashion style and even language (because I'm international student). I can learn English from MTV.

- I find out MTV is more than just music because there are tons of different things in this channel.

- I like MTV because everything is in 1 channel, even the advertisements are interesting and entertaining. 

-MTV is the channel I can relate to.

4. How does MTV change your life?

-MTV includes musics and real life shows.

-Music changes my life because almost songs are telling the story of life and it's beauty, wonder, struggles and causes. When I'm sad I can listen to a song about struggles and I might feel better. It's really change my mood.

-Real shows are the key. The reason they called "real show" because it relates to our life. Sometimes in the real show I find that I have the same situations as a character so I feel I'm not different from others. Others also have a moment that it worse like me.


-MTV is like a morning paper for youths and for me. It likes a routine for the day to update the world by shows, music, advertisement, fashion, style, your idols, your idols information...


-MTV is also a part of art that might give me the ideas of art, creations or innovations. 

Chemistry - Term 3

A. History of naming formula

Naming formula or the language of chemistry was largely based on the work of Antoine Lavoisier (Father of Modern Chemistry). He worked to translate the archaic and technical language of chemistry (about 19 century). Then the names of formula was developed by a group of scientists. Elements are represented by symbols. Each formula has a name unique to that formula.

B. What is the concept behind the naming?

In the past, the chemists used formula or elements by drawing or using shape to describe the formula. But it very hard to understand so that naming the formula made it easier to understand and to use at more interesting for people to learn. Naming the formula allows chemists and people to communicate in words rather than in chemical symbols.

C. Does "ate" represent 3 Oxygen atoms?

No, it doesn't. There are many formula that have "ate" but more than 3 oxygen. Example: PO4 (phosphate), SO4 (sulfate)

Global Warming

What is Global Warming?

Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.

 

The Causes

Global Warming is caused by many things. The causes are split up into two groups, man-made causes, and natural causes.

Natural causes: are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years.

Man-made causes probably do the most damage. There are many man-made causes.

Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well. 

Another major man-made cause of Global Warming is population. More people means more food, and more methods of transportation. That means more methane because there will be more burning of fossil fuels, and more agriculture. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem with the increasing population is transportation. More people means more cars, and more cars means more pollution.

Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2. Also, the trees that convert our CO2 to oxygen are being demolished because we're using the land that we cut the trees down from as property for our homes and buildings. We are not replacing the trees (an important part of our eco system), so we are constantly taking advantage of our natural resources and giving nothing back in return.

The Effects 

Global warming will increase the frequency or intensity of many kinds of extreme weather.

Global warming heats our oceans. Since hurricanes derive their power from warm waters, scientists expect more ferocious hurricanes.

 

Hurricanes cause do billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these.

Hot, dry conditions are perfect for sparking wildfires.

Higher temperatures cause water to evaporate faster, leading to dried-out soil that increases water shortages and puts crops and livestock at risk.

Ice caps melting

 

Warmer temperatures along with associated floods and droughts are encouraging worldwide health threats by creating an environment where mosquitoes, ticks, mice and other disease-carrying creatures thrive. The World Health Organization (WHO) reports that outbreaks of new or resurgent diseases are on the rise and in more disparate countries than ever before, including tropical illnesses.

Species loss and endangerment is rising along with global temperatures.

The Solutions 

The Awareness

Advertising Method: Organize a group of volunteer people wear green T-shirt walk around the city to donate people a small paper bag of seeds. Encourage them to plant at their house.

(something like this)

Give them a paper of simple personal things to do to save the environment. Invite people to this organization.

Biology - Assessment Task 2

Siberian Tigers

 

-The Siberian tiger also known as the Amur, Altaic, Korean, North Chinese or Ussuri tiger.

-Type of species: Mammal 

-One of eight different subspecies of tigers and the largest cats currently living on Earth.

-Is a subspecies of tiger which once ranged throughout Western Asia, Central Asia and eastern Russia, and as far east as Alaska during prehistoric times.

-Is the biggest of the eight recent tiger subspecies and the largest living felid, attaining 320 kg in an exceptional specimen.

^-Genetic research in 2009 revealed that the current Siberian tiger population is almost identical to the Caspian tiger, a now extinct western population once thought to have been a distinct subspecies.

 

Habitat

-There are about 330-370 adult Siberian tigers left in the wild (at early 2009).

-Its range is limited to the Amur region of Russia in the Far East (most are here), where it is now protected and China (very low population, 18-22) and possibly Korea. The region (i.e. distribution of this tiger) is shown on the map below:

-A Siberian tiger cub, a naturally very precious animal, was found trapped in a woodpile in the snowy northeast of China. This is the first time the Siberian tiger has been seen in China for 60 years according to the Times author.

-Within the regions in Russian where this tiger can be found is, for example, the area of Sikhote-Alin Zapovednik. Sikhote-Alin is a mountain range in Primorsky & Khabarovsk Krais. It is about 900 km to the NE of Vladivostok. "Zapovednik" refers to a protected area in Russia. These areas are kept wild.

-This is a picture of Central Sikhote-Alin, which is Siberian tiger habitat and a UNESCO World Heritage Site:

-The mountains of the area are densely forested with birch and conifers on higher slopes. On the lower slopes there is mixed deciduous forest. This area generally is one of the leading lumbering areas of the Russian Far East. Minerals are also mined in the area. No doubt outside the protected reserve these activities have a substantial negative impact on the Siberian tiger habitat and the tiger's survival, therefore. The human population is sparse.

-Unlike some big cats like lions, adult tigers like to live alone (except for mother tigers with cubs). This is partly because in the forest, a single tiger can sneak up and surprise its prey better than a group of tigers can.

 

Diet

-Siberian Tiger is a Carnivore.

-As these animals live in the cold climate where the winter is almost all the year round and that is why they need a lot of meat. They must eat at least 20 pounds a day to keep fit and they may eat up to 100 pounds at a time. Their strength allows them to drag prey for long distances, and if there is too much food, they hide it in secure places. They spend almost all of their time hunting. 

-The Siberian tiger's main prey was wild boar, though it occasionally fed on roe deer, red deer and domestic animals such as dogs, pigs, sheep, and cattle in winter.

A Sample of Food Chain

Sun --> Plants --> Deer --> Siberian Tiger

Why are Siberian Tigers Endangered?

 

 

-There are a lot of reasons because of which the population of these animals decreases; the main one is the fact that man influences greatly the life of the animals. 

-Poaching was unquestionably the most serious threat to the Siberian tiger's existence. All tiger sub-species have been hunted by humans since ancient times. Per to the WWF (World Wildlife Fund), "tigers are poisoned, shot, trapped and snared, and the majority of these animals are sought to meet the demands of a continuing illegal wildlife trade - which includes traditional Chinese medicine." 

-China made medicinal usage of tiger bones illegal in 1993. However, tiger parts are highly valuable, their trade lucrative even today.

-Even though it is illegal to kill a tiger, wild tigers are still being poached today because their bones, whiskers and other body parts can be sold on the black market for a lot of money.

-The other vital concern for the survival of the Siberian tiger in the wild is habitat loss.

-Research has demonstrated the Siberian tigers require vast forest landscapes to survive. However logging, both legal and illegal is threatening the tigers home by fragmenting their habitat thereby isolating them from each other.

-In addition, the continuous creation of new logging roads provide poachers with access to formerly remote areas.

-So in essence, for the Siberian tiger to survive in the wild, and no longer be considered and endangered species two things must happen. First, habitat encroachment must stop and secondly, the thousands of years old tradition of using tiger parts for medicinal purposes must also end. 

Conservation Efforts

Siberian Tigers in Russia

In this century, the Siberian tigers (sometimes called the Amur, Manchurian, or Northeast China tiger), have survived four wars, two revolutions, and now an onslaught on its forests. There are three protected areas for tigers in Russia-the Sikhote-Alin (3,470 km2), Lazovsky (1,165 km2), and Kedrovaya Pad (178 km2) Reserves-inland from the Sea of Japan in the Russian Far East.

Siberian Tigers in China

Sightings of Siberian tigers in Changbaishan, near the Chinese border with North Korea, were reported in Chinese newspapers in 1990, and some are still found along the Russian border. The Cat Specialist Group suggests that there are probably fewer than 50 Siberian tigers in China.

Siberian Tigers in Zoos

The captive program for Siberian tigers is the largest and longest managed program for any of the subspecies. The Siberian tigers tiger served as one of the models for the creation of scientifically managed programs for species in captivity in zoos and aquariums worldwide. According to the 1997 International Tiger Studbook there are about 501 Siberian tigers managed in zoos. This captive population is descended from 83 wild-caught founders. For the most part, the Amur or Siberian tiger is considered secure in captivity, with a large, genetically diverse and stable population.

-ZSL's Amur tiger conservation project is focused on non-invasive population monitoring, anti-poaching efforts, and increasing education and awareness.

-This project is run by tiger biologist Linda Kerley and her husband Misha Borisenko, an expert wildlife tracker. Linda and Misha need more funds for buying camera traps and to keep the jeep running. If you would like to donate, your funds would be helping to secure a future for both Amur tigers and their smaller cousins, the Amur leopards.

 What we can do to help conserve them?

Conserve Habitats

 
    •    One of the most important ways to help threatened animals survive is to protect their habitats permanently in national parks, nature reserves or wilderness areas. There they can live without too much interference from humans. It is also important to protect habitats outside reserves such as on farms and along roadsides.

    •    You can visit a nearby national park or nature reserve. Some national parks have special guided tours and walks for kids. Talk to the rangers to find out whether there are any threatened species and how they are being protected. You and your friends might be able to help the rangers in their conservation work.

    •    Some areas have groups which look after local lands and nature reserves. They do this by removing weeds and planting local native species in their place. You could join one of these groups, or even start a new one with your parents and friends. Ask your local parks authority or council for information.

    •    By removing rubbish and weeds and replanting with natives you will allow the native bush to gradually regenerate. This will also encourage native animals to return.

 

*Encourage others to avoid traditional Chinese medicines that use tiger body parts. Poachers kill an average of one wild tiger each day, mostly for use in traditional Chinese medicines. Historically, people believed that tiger parts had healing powers, but the practice has continued despite research showing no exceptional value from the use of tigers.

*Support the enforcement of bans on the killing or international trade of tigers or tiger parts. Although many countries have signed on to Convention on International Trade in Endangered Species of Fauna and Flora agreement with regards to tigers, killing tigers continues.

*Donate money to tiger conservation organizations that use the money to fund research on tiger habitat and behavior. These organizations also fund education programs and in some cases, purchase tiger habitat to protect it from development. By giving money to the organizations, you will be helping to conserve tigers around the world.

*Support accredited zoos and wildlife sanctuaries that actively participate in tiger research and conservation. Some accredited zoos have captive breeding programs and many spend time researching tiger behavior and health.

*Volunteer to work with conservation organizations to educate and mediate with farmers who live in tiger habitats. Conflict between tigers and humans can lead to killing tigers. Working with local individuals to reduce their dependence on forest lands allow habitats to be saved and it reduces conflicts.

*Take an eco-tour that focuses on tigers. Tourism dollars produced by responsible tours can help convince governments and businesses that tigers can be profitable in the wild. This creates incentive to protect tigers in their natural habitat.
