Pike River Mine Explosion

 Pike River Mine Explosion,  Nov, 19th 2010.

I think it's gonna be about a mine cavern that exploded in New Zealand on November the 19th 2010.

I think i will find out if anyone died / how many people died, and how/why it happened.


1. The Pike River Mine is located the West Coast of South Island of New Zealand

2. The building of the mine started in 2005 but the actual mining started in November, 2008

3. 31 Men were inside the mine at the time of the explosion.

4. Two Men escaped the mine explosion, the the 29 died inside the mine

5. Because it was far too dangerous to send human searchers into the mine to find the bodies, so instead they sent in robots.

6. Jacinda Adern made a promise to unseal and re-enter the mine, also going to send in a searching team to see what or who they could find, but it failed, they couldn't.


Videos;

Video #1

-One of the survives tells people that he ducked behind the door of the loader to avoid falling rocks.
-Russel was left for dead by an electrician who saw him lying on the ground
-Another survivor, Daniel rescued Russel and helped him escape
-They turned on taps to help clear the smoke
-Daniel and Russel are the only two who got out, 
-Daniels younger brother of 21 years, didn't make it out of the mine
-They still don't know why the mine exploded

Video #2 

-The mine was extremely gassy but no one thought it wouldn't explode that's why they entered
-Russel felt more peaceful before he passed out
-In the mines the miners were trained that mine rescuers would save you so you should wait to be rescued
-The people blamed the corporation for the explosion and the 29 deaths.
-People were mad at the manager at the time (Ben and Daniels father, Ben died)
-Daniel has a wife (Tammy)

Reflection
I am learning about the Pike River Mine Explosion
This work shoes my learning because it is about the Pike River Mine Explosion
I am wondering if anyone did survive, even thought i know that is impossible to find out
I got all my predictions correct about what happened and when it happened.

Extra from the extra reading thingy

Notes
- The explosion happened Friday 19th Nov 2010
- The planning started in 2005
- The mine opened in 2008 and was almost shut down due to the gas
- On the day of the explosion at 3:44 Ben (Daniels brother) was deep into the mine whilst Daniel and Russell were closer to the top.
- The company was ordered to pay $110,000 to each family but could only afford to pay $5,000 to each family due to the fact it had to be shut down because they couldn't sell coal
- The coal in Pike River Mine was discovered in 1946 but the planning for the mine started in 2005
- Jacinda Adern promised to re-open the mine and re-enter to find the bodies.
- The Pike River Mine explosion was the worse mine disaster in New Zealand since 1914.

Questions

there was too much gas and it almost made the mine shut down once it first opened in 2008

That the mine had violated multiple health and safety codes/rules, and that the explosion had been caused by the ignition of a large volume of methan.
Because the two men that did escape, Daniel and Russell, were closer to the opening of the mine, and both had something that helped them, ducking behind something or for Russell he was in the cab of the truck.

-

1. The first person to discover coal in the paparoa ranges was Harold Wellman
2. The prime minister promised that she would open and re-enter the mine.
3. The Pike River Mine is located on the West Coast of the South Island of New Zealand.
4.the explosion happened the 10th of November 2010
5. The reason was that the company was broke because they were unable to sell any more coal.

Two questions i had once reading the article was, 'why didn't they close it in 2008 when the gas almost shut it down the first time' and 'what if there were more people down there that they didn't register'  




Term 3 reflection

 Term 3 Reflection


A highlight for me would be the science experiments, because they help you learn and are also very fun.

I found lock-down enjoyable because i could eat or drink whenever and chose what time i did work or for how long.

My favourite subject have either been Disasters with Mrs Handley, or Science with Mr Stock, I liked Mrs Handley's class because I like learning about disasters,  when they happened, and more facts like that, and i liked Mr Stock's class because the experiments were fun and he was teaching us higher class science to help us learn better and faster.

I created a balloon/paper mashe mask, i slightly enjoyed Arts Kete, but not as much as the steam project, because the steam was funner and gave you more ideas to base off of and more time because lock-down cut through the Arts Kete.

I am looking forward to being able to sleep longer in the holidays.

Clay-stop-motion

This is mine and my groups Clay stop-motion,  

Our characters are

The creepy cat.

 Snow-Maid
The Carrier Cat
----------------------------------------------------------------------------------------------------------------
The people in my group are; Susie, Quaid, and myself.
----------------------------------------------------------------------------------------------------------------
My storyboard;


----------------------------------------------------------------------------------------------------------------
Our plan was to get aliens to both meet and become acquaintances on the alien world looking for food.
----------------------------------------------------------------------------------------------------------------The way we did it is we got a black paper and drew some planets on it (Susie did) and we flicked white paint onto it for stars and then we tapped it to the leg of the table and set up our computer slowly moving it step by step 
____________________________________________________________
I think the background worked well for the stop-motion because it set the scene and it was a nice representation of where it was and that they are aliens
____________________________________________________________
I would maybe add more depth into the characters and maybe plan it a bit better because we just went with the flow and added things in the middle of the stop-motion

FINAL MOVIE


Hands on fire


Aim:
I want to Safely Light my hands on Fire

Method:

  Equipment
Detergent  
- A Lighter
- Safety Glasses
- Gas 
- Tray
- Hose


Instructions
1. Collect  your equipment
2. Put some water in the tray
3. Put some detergent into the water
4. Put safety glasses on
5.Tie up any loose hair
6. Take off any accessories on hands and arms
7. Wet hands, wrists, and arms up to your elbows
8. Bubble the gas into the water
9. Scoop the bubbles but don't touch the water
10. Keep your hands with the bubbles straight in front of you away from your face and your arms straight
11. Light the Bubbles on Fire with lighter
12. To get rid of the fire move both your hands facing outwards still straight in front of you
   
Results:
After following the instructions Mr. Stock lighted the kids hands on fire, them all being safe, as a fire light upon their out stretched hands, after a second, out of shock they quickly put their hands in front of them, the fire disappearing, a smile laid on the kids faces, wanting to do it again.

Colourful Skittles

 Aim:


I want to find out what happens when you mix Skittles colours.

Method:

Equipment

- Skittles
- Petri Dish
- Warm Water
- Beaker 
- White Background

Instructions
1. Get your Equipment
2. Place Petri dish on the white background
3. Put your Skittles around the inside edges of the petri dish
4. Pour warm water gently into the middle of the petri dish
5. Observe what happens
Prediction: 

I think that the Skittles will get all the colour drained (become white).


Results and Conclusion

When the water was poured the colours started fading on the underneath and the colours drifting to the middle slowly.

Discussion;
1. The colours dissolved into the water  
(When a solid is mixed into a liquid, creating a solution)

Why did the colours spread?
The food colouring and sugar peels off staining the water, 
when you pour warm water over it the colour go along with the water
then spreading through the water into the middle till all the water is coloured)

Once the colours dissolved into the liquid
the high concentration of colour moved into the middle where there
was a low concentration of colour this is called diffusion

What is a Base?

 pH means potential/power of Hydrogen

The strength of an Acid is measured on the pH scale, it starts from 0, to 14.
If the water turns-

-Red it is 0-1 on the pH scale
-Orange it is 2-3 on the pH scale
-Yellow it is 4-6 on the pH scale
-Green it is 7 on the pH scale
-Blue it is 8-9 on the pH scale
-Indigo it is 10-11 on the pH scale
-Violet it is 13-14 on the pH scale

As you can tell it is all the colours of the rainbow
Adding a few drops of Acid makes it from 0-6 depending on how much you add 
Adding a couple drops of Base makes it go between 8-14 depending on how much you add
having it balanced in the middle makes it green, the number 7, on the pH scale, also meaning its just plain water, 

How it works is the acid and the base balance each other out, meaning they both are basically not even in the water.

Also to make it work put green food colour into the water making it plain green water, also when you add the acid or base, stir it, but don't use something that can change the outcome, r that the acid or base will harm.

pH is the log, or the hydrogen concentration, log is a mathematical term for counting how many decimals there are in a number.

Any Base is the polar opposite chemical of any Acid.

A Base contains hydroxide as an Acid contains Hydrogen.

adding the same amount of Acid and Base makes them cancel each other out, where as if there is more acid, the acid will take over, and vice versa.

H (Acid) -OH (Base)

An Acid and a Base neutralises the chemicals creating HOH or Water (H2O) 

Conclusion

A base can be different things in chemistry, more known as a chemical, that changes most things colour, like it can change plain green water, to a cyan, deep blue, indigo, or violet, and can change red litmus paper to blue, It's also known as an polar opposite of the other chemical, Acid.

What is Acid?

Names of Acid
Hydrochloric Acid
Sulfuric Acid
Nitric Acid
Phosphoric Acid
Acetic Acid
Citric Acid
Formic Acid
Tartaric Acid 

Formulae of Acids
HCl (L not I)
H₂SO₄
HNO

H
PO
CH
₃COOH

Formic Acid = The poison bee sting (The only way to get the Acid out is toothpaste, put Vinegar on Wasp Sting)

Where do you find Acid?
Plaque Acid on your Teeth (Toothpaste can help)
Stomach Acid (Hydrochloric Acid)
Battery Acid (Sulfuric Acid)
Lemon and Orange Acid (Citric Acid)
Vinegar (Acetic Acid)
Bee-String (Formic Acid)
Coca Cola (Carbonic Acid)


What is Acid?
An Acid is a chemical that contains Hydrogen Atoms that break off to react with different substance's.


Litmus Paper changes colour in Acid, Blue litmus paper changes to red, red litmus paper doesn't change in Acid, so if you put red litmus paper in acid it doesn't change.


Red Cabbage Indicator

 

Aim;
I want to find out how to tell if something is an acid.

Method;

Equipment;

- Beaker 
- Red cabbage
-Boiling water
-Test Tubes
- Hydrochloride Acid and Hydroxide
- Dropper

Instructions
1.  Collect and set up Equipment
2. tear the Red Cabbage into small pieces and put in beaker
3. Pour 100mm of the freshly boiled water into the beaker.
4. Add 2cm of the acid to one of the end tubes, the big one and 2cm of the Hydroxide to the other
5. Add the Red Cabbage water into the two tubes using the dropper
6. Watch the colours and mix them seeing what colours you can make.

Results;

The mix made multiple different colours, we could even layer colours on top of one another, with only the two main colours, yellow and pink, we made purple, blue, a brighter pink, a greenish blue, and green. The colours were nice to watch mix.

Homemade Sherbet

 Aim; I want to find out how to make sherbet

Research


Method;

Equipment

- Cup

- Baking Powder

- Citric Acid

- Sugar or Raro

- Popsicle stick

-Teaspoon

Instructions;

1. Get your equipment

2.  Add a teaspoon of raro/sugar into the cup

3. Add half a teaspoon of baking powder into the cup

4. Add half a teaspoon of citric acid into the cup 

5. mix the substance with the Popsicle stick

6. Taste the homemade substance, adjusting only if you need it

-baking powder to balance the citric acid and vice versa-

Results;

Once mine went in my mouth it gave a small sting in my mouth and nose before calming and tasting nice and sweet with a small amount of foam, the reason it foamed was because the gas carbon dioxide was made in my mouth by the powders as they mixed along with my saliva.

Discussion;

Citric Acid + Sodium bicarbonate --> Carbon Dioxide

or

C6H8O7 + NaHCO3 --> CO2

The Mount Eberus Plane Crash; November 28th, 1979

  The Eberus Plane Crash; November 28th, 1979


I think this disaster will be a plane crash on the 28th of November 1979, and there are no survives, and it crashes into snow.

I think i will find out where it happened and how people were on the plane, why no one survived, why were they in Antarctica.


1. IT was heading on a sight seeings trip around Antarctica, seeing McMurdo sound, Scott base,

2. Captain Jim Collins and co-pilot first officer Greg Cassin

3. So passengers could get a better view of the outside, not knowing he was flying into a mountain.

4. The flight path had been changed but the pilot and co-pilot hadn't been told, and they couldn't see where they were going because of the white out, meaning they couldn't tell the difference between the land and the sky.

5. The crash happened at 12:49 PM on Wednesday November 28th 1979, but it took till 1:25AM to find the remainder of the crash.

-

Video #1

-is the worst new Zealand air disaster 
-the plane picked up people from both Auckland and Christchurch
-There were two flight engineers
-there were five flight crew and 15 fight attendants
-the navigation doesn't work as well near the earths poles
-the Erebus mountain is an active volcano
-international navigation system (INS)
-they were only supposed to go down to 6,000 feet but they went down to 450 feet.
-they were 30/40 feet away from where they thought they were

Video #2

-It took off from Auckland at 8:00 AM
-IT made a 45 minute stop at Christchurch to pick up more people
-$359 per person for the sightseeing plane
-There were 237 passengers aboard the plane
-2,000 feet of snow
-They said that they should go down to 1,500 ft
-It thought the snow was still clouds
-they circle twisted whilst descending
-unknown to the crew the aircraft was flying towards Erebus mountain, since it is covered in snow it is hard for the crew to see it.
-12:49 the alarm tells them to pull up
-they tried to turn the plane around but were unable to as it was to late.
-The aircraft broke and caught fire

We are learning about the Eberus Plane Crash,

This work shows my learning because its stuff i learnt about the plane crash

I am wondering how everyone died, like they can't have all died from impact, some probably bleeding out and stuff.

Looking back on my predictions i was correct about what it was and the date and time.
