Textbook notes

Chapter 16 Section 1


A mineral is a naturally occuring usually inorganic solid that has a characteristic chemical composition, an orderly internal structure, and a characteristic set of physical properties.
Minerals are made up of atoms.
Ore Minerals: Minerals that are valuable and economical to extract are known as ore minerals. 
Metallic Minerals: Ore minerals are either metalliic or non metallic. Metals conduct electricity have shiny surfaces, and are opaque. The are mostly negative
Non Mentallic Minerals: Tend to be good insulators, have shiny or dull surfaces, and may allow light to pass through them.
Non metals are among the most widely used minerals in the world.

Section 2
Mining companies can indentify areas where there is a high likelihood of inding valuable mineral resources inquantities that are worth mining.
Exploring rock for mineralization is the first step in finding an ore deposit.
Planes are carry instrunments that indentify paterrns in gravity, magnetism, or photographs of an area.
Subsurface mining: Earth's surface are mined by using Subsurface mining methods.
Surface mining methods are used when ore deposits are located close to Earth's surface.
When rock weatehrs and disintegates, minerals within the rock are released.
Placer deposits: These minerals are concentrated by wind and water into surface deposits called placer deposits

Section 3
Because of the potential environmental impacts of mining on such a large scale, mining has become one of the most heavily regulated indistries in the United States.
The Environmental impacts of mining: In the United states, the federal and state governments and mining companies are spending billions ofdollars to clean up abandoned mines.
Surface mining can cause both air pollution and nouse pollution. Noise is crated by the equpment taht is used in a mine as well as by blasting.
Because of air and nouse pollution, most surface mines are not located near urban populatins.
Water resources can be negatively impacted by mining. Coal or minerals that contain a lot of sulfur can cause a similar problem.
Displacement of wildlife: Removing soil from a surface mine site strpis awat all plant life. Dredging can negatively affect aquatic ecosystems and physically chagne the bottoms of rivers.
Subsidence: The sinking of regions of the ground with little or no horizontal movement.
Reclamation: The process of returningland to its original or better condition after mining is completed is called reclamation.

Chapter 17 section 1

The fuels we use to run cars, ships, planes and factories and to produce electricity are natural resources.
Fossil Fuels are the remains of ancient organisms that changedinto coal, oil, or natural gas. Fossil fuels are central to life in modern societies.
The energy in fuels is often converted into electical energy in order to pwoer machines.
The quality of coal varies.
An electric generator is a machine that converts mechanical energy, or motion, into elevtrical energy.
Everything from the food you eat to the clothes you wear requires energy to produce.
There are dramatic diffrences in fuel use and efficiency throughout the world.
Petrolcum: Oil that is pumped from the ground is also know as crude oil, or petroleum.

Section 2
Nuclear power plants get their power from nuclear energy, the energy within the nucleus of an atom.
These collisons cause the nuclei to split in a process called nuclear fission.
A nuclear reactor is surrounded by a thick pressure vessel that is fulled with a cooling fluid. The pressure vessel is designed to contain the fission products in case of an accident.
Nuclear energy has many advantages. Nuclear fuel is a very concentrated energy source.
Building and maintaining a safe reactor is very expensive. As a resuly nuclear power is no longer competivive with other energy.
The difficulty of finding a safe place to store nuclear wastes is one of the greatest disadvantages of nuclear power. The fuel cycle of uranium products fission priducts that can remain dangerously radioactive for thousands of years.
Nuclear fission: One possible future energy source is nuclear fusion.  Nuclear fusion occurs when lightweight atomic nuclei combine to form a heavier nucleus and relase tremendous amounts of energy.

Earth Hour notes

Erin
Earth Hour is not effective.
in canada, the largest electricity company said 205 megawatt reduce of energy which is about reduce in 75%.

using candles mean producing more C02

May

agree with earth hour. even though does not really help, it is smth that brings ppl together.

-if don't use beeswax candle, other candles will produce carbon dioxide.
-battery stays for a very very long time after you throw it away.

-In sydney, during that hour, they dropped 7-12% of energy consumption.

Nam

earth hour will help people.

-bring awareness to people and bring concern to ppl that earth is in danger.
-earth hour is actually saving energy in a long term.



-the candles actually produce a lot of carbon dioxide.
-need more energy to bring back the electricity.

Dina and Inaho

if we join earth hour, we can save the energy.


-in thailand, 1,699 megawatt of reduction during earth hour 2013.


-earth hour will cause emission to increase.

Sonia and Ruchika

Earth Hour is really helpful.

-helps to reduce the usage of energy globally all around the world.


-candles release many potential harmful chemicals into the air.

Alice and Jessica

earth hour is not that good. Only 1 hour.

in asia, a lot of celebrities are supporting for this campaign.
-earth hour actually emit a lot of C02 because people use a lot of candles.

PLoy: Earth hour rises to the whole world.
Against: turning on and off lights will use more energy
People will commit crimes, more accidents
Lily and Jane: Maximum participation of consumer. Many countries joined for earth hour.
Raise awarness about earth hour
Earth hour took place on saturday. Eco repts estimate over 200 people came out to show how much the university of arizona cares about the environment.
Earth hour was first conceived by the WWF in Australia in 2004 in resopnse to scientific data that showed impact of climate change.
Leila: Earth hour provides material for schools
Earth hour teaches a two part lesson pla in educating on the carbon footprint.
Social values: Unity amongst a commuinity.
Global scale of awarness
Percenption of capacity without electrity.
All of earth's electricity off=4minutes of China's power plants off
"natural" candles used. Electicity should be celebrated not shunned.

When i first heard about the Earth Hour, I was against it. I thought that Earth Hour was a good event but not that good to save the Earth. But as I learned and knew more about the Earth Hour it taught me something. It taught me that Eventrough one hour won't make a change to the earth it will atleast give an awarness to people who doesn't know the seriousness of the earth right now. This event is not just an event. Its an event that reminds people that our earth is in a problem and we have to do something about a place we are living in. I also think there are a lot of factos in this event such as environmental, and educational.


I think we spent a lot of time studying and presenting the idea of Earth Hour. We asked teachers about how they think about Earth Hour. And many people had a different perspective on Earth Hour. Some people were against and Some people were agreeing with it. From this, I've learned that we have to spread the idea of Earth Hour to the people who are against it and people who doesn't know anything about Earth Hour. I learned a lot from this project and i really want to support Earth Hour.

Songkran Homework

 

 

There are the 3 items i've used during Songkran break. NAMTHIP, BICYCLE, and THERMOS. I used them everyday. I strongly believe that by doing and using these items will help the environment. I think everybody should start thinking about the environment and atleast do something about it.

Thursday Class - Earth Hour Project Part 2 - continued

The concept of Earth Hour is to raise awareness of the human impact on the environment. In 2008, Earth Hour had tens of millions of participants. This is where Earth Hour was truly successful. In just three years, tens of millions of participants worldwide were increased to over 1.3 billion participants worldwide. People are also now more aware of the concept of carbon footprints and the idea of renewable energy.
Even if this is merely a symbolic event, and does not actually save any energy in total, it is truly inspirational that so many people worldwide can come together for one event. Earth Hour raises awareness that our environment is fragile and that even a small change could help improve it.

Ontario’s Independent Electricity System Operator (IESO) reported that that on March 26th, 2011, between 8:30pm and 9:30pm, due to conservation action during the last episode of Earth Hour, province-wide demand for electricity fell by 360 megawatts or 2.1% compared to a typical Saturday evening in late March.

1. Attention –  Seizes our attention, if but for an hour.
2. Awareness – Bringing awareness of sustainability issues.
3. Action – Inspiring action towards sustainability, beyond the hour.

Earth hour debate

From Mr. Eubin:
1. Yes, Heard it from BBC
2. Their idea is good and eco friendly, but it's actually not helping and also not changing anything.

3. It's actually not helping people whould turn off their light for an hour and the next day they would just drive their big cars everywhere
4.No, because it's not helping anything. 


My hypothesis:
 I think Earth Hour is a bad idea. The earth hour might help the enviornment but just a little. People will just turn off the light for an hour and the next day they will just drive their cars and turn on air condition. It might be a good idea but I think there are many ways to save the earth beside 'Earth Hour'.
