Social Studies Treaty Assessment :)

Introduction 

In 1830 there were Maoris killing Maoris with muskets, people drinking and doing drugs, prostitution and fighting, and this needed to be stopped.. With what? A treaty. 

Paragraph One (Lawyer)

In 1830 there were around 100,000 Maori's compared to approximately 200 Europeans, of the 200 pakeha many of them were whalers. The Europeans would stop in Russell, drink huge amounts of alcohol when the came to shore, leading to rising rates of prostitution, fighting, diseases. This lead to Russell earing the name hellhole of the pacific. Without a treaty being put in place issues like this could've arises again and causing even more problems than necessary. 

Paragraph Two (Lawyer)

Another reason that a treaty was needed was to protect Māori rights. One group that felt strongly about this was the missionaries. Missionaries protected the maoris rights as best as they could and went through great lengths to make sure the maoris were treated with respect. You are able to see they tried their hardest to help the maoris because after concerns about large land sales having an impact on the maoris they purchased land for them in order to make sure they still kept a quantity of land. The missionaries were greatly worried about some of the foreigners behaviors to the land and people of New Zealand. The missionaries concerns greatly impacted the maoris decision to sign the treaty. 

Paragraph Three (Hammer)

Another reason that a treaty was needed was the Musket Wars.  Between 1807-1842 over 20,000 Maoris were killed due to musket wars. Before muskets were introduced to NZ they used homemade weapons such a taiaha and a mere. Some maori would be defenseless and vulnerable without muskets, and to get them they would have to trade their crops,food and women. It was a guessing game for the maoris, not knowing when another tribe (with muskets was going to attack). As more tribes got muskets, more musket wars followed, either for revenge or self defense for land. The introduction of the muskets had changed New Zealand forever, the populations have shifted over the years. Having the treaty has prevented musket wars from becoming a threat to everyone. Laws are now in place for guns and wars.

Paragraph Four (The Slam Dunk)

The declaration of independence was needed to basically protect and help New Zealand grow as a country, they agreed to trade and be friends with the British because their past encounters with the french have been a little uneasy.. Or in other words..stabby, They had written to the British king and asked for protection from all the other countries trying to take over new Zealand. The declaration and the New Zealand flag ( the first one ) basically made it easier for maori to declare their land.

Conclusion (Robust Conclusion)

In conclusion, a treaty was needed because to resolve all of the issues that New Zealand. Without a treaty issues like the musket wars would’ve kept happening. People would of kept dying and today in New Zealand as we know it will not be the same. The treaty is important to today's history 

forces

introduction to forces

a force is a push or pull and is measured in newtons (N), named after Sir Isaac Newton. Forces are measured using a newton meter and have both a size and a direction.
You cannot see a force but often you can see what it does. Forces can make things movie, speed up or make already moving objects slow down. Change the direction they are moving in, and change the shape of things



balanced and unbalanced forces

Balanced forces are forces that act on an object but cancel each other out because they are the same size and are acting in opposite directions. This means that there will be no net force on the object.  If there are forces acting on an object that is acting in the opposite direction and are different sized they are said to be unbalanced.


friction

 Friction is a force that occurs when two materials rub together. Friction always acts to oppose ( prevent or stop ) the movement of an object. Drag is another name for the friction that occurs when an object moves through a fluid, such as air or water. The effects of friction can be reduced if the surfaces of the two materials are lubricated, ( with water, etc). Friction can be increased by making one or more of the surfaces rougher or by pressing them together more strongly


calculating speed

 Speed is a measure of how far an object can travel in a certain amount of time. We often use kilometers
per hour in everyday life, However. scientists generally use meters per second as it is a more accurate measure of speed. To calculate speed, we need to know two variables - distance traveled and time is taken to travel the distance.

geology

plate tectonics

plate tectonics ('tectonics' means 'building') is the name of the scientific theory that states that the crust is made up of 12 major plates and that these plates are moving at different speeds and directions. Their movements cause earthquakes and volcanism. The places where two plates meet is called a plate boundary. Earthquakes and volcanoes are most likely to occur either on or near plate boundaries.


inside the earth

The earth is made up of four district layers, the outer most layer of the earth is called the crust, in geology, the crust is the outer most solid shell of a rocky planet, dwarf planet or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup.
The crust is the thinnest layer between 0-60km thick. The crust is the solid rock layer upon which we live, there are two different types of crust: continental crust, which carries land, and oceanic crust, which carries water. continental crust is thicker than oceanic crust.


power to move plates

Tectonic plates are floating on a layer of molten (liquid) rock - the mantle. The mantle near the core is much hotter than the mantle near the crust. The temperature difference sets up convection currents and causes the movement of the tectonic plates.


plate boundaries

Divergent boundary: divergent boundaries occur when two plates pull apart, new crust is created as the plates pull away from each other when a diverging boundary occurs on land a rift separating over time, and the mass of land will break into smaller parts.

convergent boundary: convergent boundaries occur when two plates come together when oceanic crust collides with continental crust, the denser oceanic crust is destroyed and recycled back into the interior of the earth when two continental crusts collide neither plate may subduct and mountains may form as both plates are pushed together

transform plate: Transform boundaries occur
when two plates slide past each other. Most transform faults are found in the oceans. However, a few of them occur on land.

medical

Skeleton

The skeleton is the body part that forms the supporting structure of an organism. It can also be seen as the bony frame of the body which provides support, shape and protection and protection to the soft tissues and delicate organs.

Your skeleton has 206 bones, However, when you were a child you had as many as 350 as some of the bones fuse together as you grow, more than half of your 206 bones are found in your hands and feet. The largest bone in your body is your femur (thigh bone). The femur is connected to the tibia and fibula ( shin bones ) and the pelvis. Your humerus or as some people say your funny bone. is connected to the radius and the ulna ( forearm bones ). Your shoulder blade is called the scapula. and your collar bone is known as the clavicle. Your ribs are joined to your sternum ( breast bone ). The bones in your fingers and toes are called phalanges. Your head contains two major bones. The cranium ( skull ) and the mandible ( jaw ). The smallest bones of the human body are found in your ear - the hammer, anvil, and stirrup.


x-rays

X-rays are used to produce images of bones to check for damage, such as fractures. X-rays mostly pass through the skin and soft tissue, but they do not easily pass through bone.


Muscle

Muscle works by making themselves shorter, We say they contract, and the process is called contraction.
Muscles are attached to bone by strong tendons. When muscle contracts, it pulls on the bone, and the bone can movie if its part of a joint.

An example of antagonistic muscles: The elbow joint lets out the forearm move up or down. It is controlled by two muscles, the bicep and the front of the upper arm, and the triceps on the back of the upper arm. The biceps and the triceps are antagonistic muscles.


Joints

If two bones move against each other, they would eventually wear away. This can happen in people who have a disease called arthritis. To stop this happening, the ends of the bones in a joint are covered with a tough,
a smooth substance called cartilage.
Cartilafe reduces friction and acts as a shock absorber. It is kept slipper and lubricated by synovial fluids produced by the synovial membrane.
Tough ligaments join the two bones around the joints and stop it from coming apart.

metals

Alloys
An Alloy is a mixture of two or more elements, which means one or multiple has to be a metal.
Alloys often have properties that are different from the metal they contain. this makes them more useful than the metals alone. For example, steel is an alloy of iron and carbon. it's used to make many things.. such as cars, ships, and even bridges. Steel is stronger and flexible and harder than iron and doesn't corrode (rust) as quickly. Back to Alloys, so combining the metallic elements such as gold and copper, produces red gold, gold and silver become white gold and silver combined with copper produces sterling silver.
Recent advances in technology have created a new range of alloys called smart alloys, smart alloys have unusual properties. nitinol is an alloy of nickel and titanium and is also known as a shape memory alloy. If nitinol is bent out of shape, it returns to its original shape when its either heated or an electric current is passed through it.


Metal Carbonates and acid

When a metal carbonate reacts with some sort of an acid, it will form a salt... Carbon dioxide and water. Carbon dioxide is a gas and can be seen as bubbles as the reaction proceeds.


Corrosion

When metals are exposed to the environment they can deteriorate, or break down. Scientists call this process corrosion. Rust is the term used to describe the corrosion of iron. Iron is a somewhat cheap metal so it is widely used in the industry. Scientists have had to develop a way of protecting the iron from rusting.




Chemical equations: metal + acid

When a metal reacts with an acid, a metal salt and hydrogen gas are produced. The type of sale produced depends on the type of metal and the type of acid used.

ACID                                      SALT FORMED

sulfuric acid                              sulfate

hydrochloric acid                      chloride

nitric acid                                  nitrate

genetics

Asexual reproduction

When it comes to asexual reproduction, it only really needs one parent. Why? Because it takes less time to find a mate and they don't have to go through the pregnant stage. Asexual offspring are identical to the parent, like little clones running all over the place, and because they don't have to worry about creating different genes for individuality, that means the chance to make many of that species.

sexual reproduction

different from asexual reproduction, sexual reproduction requires two parents. the offspring are similar  but not identical, the offspring is normally a combination of both of their parent's personalities/characteristics, this also means that a few of the offsprings may be better suited  to survive in their habitat.. and going into more depth about it means that the species can become more successful over time. the benefits of producing an offspring are the variation of the costs of finding a mate, breeding and producing the offspring.

the term ' species' is used by scientists to express organisms of the same type, one of the reasons for all species is to survive and reproduce, passing on their characteristics from one generation to the next.

now we are going to talk about cells, chromosomes, and DNA

first of all, DNA stands for ( deoxyribonucleic acid ).
People for generations have been asking and questioning, why do offsprings not look exactly like there parents but look similar?
 well...
all organisms are made of cells, an adult had 50 trillion to even 100 trillion of them..crazy I know.. all human cells contain a nucleus ( except red blood cells ). The nucleus is also known as the 'control centre' it contains the instructions that tell the cell how to function, Humans have 46 chromosomes in every cell in their body,  23 of these chromosomes were inherited by your dad and 23 were inherited by your mother. Chromosomes are made of a molecule called deoxyribonucleic acid (DNA), a section of DNA that contains instructions for a particular feature, for example, your hair colour is a gene as well as your eye colour and your height.

In 1962, Nobel prize for medicine was awarded to Francis Crick, James Watson and Maurice Wilkins for the discovery of the structure of DNA, He obtained PhD in 1940 from Birmingham University.

home economics

1800s the first signs of an established NZ eating pattern became evident Meat and 3 veg. The tradition of Sunday Roasts begun.	1814 Samuel Marsden came to NZ with 1 bull, 2 cows and a few sheep and poultry.	1840 food supplies were limited depending on the region in which you lived.
1870 first coal range was made locally which was larger the method for cooking in the day.		1882 Tea Examination Act was developed to ensure the quality of tea sold was pure. Became an essential part of workers day “smoko” a break hard fought by the workers.
1882 morning teas needed to keep the manual labourers well energized and often consisted on baked goods like scones.	1882 first shipment of frozen meat left NZ bound for Britain. It was the beginning of refrigeration and the start of the meat and dairy trade that is still important for our economy	1900s the next wave of NZ eating pattern  Breakfast – porridge, bacon and eggs with tea Lunch – meat sandwiches, soup and tea Dinner – a heavy meat based meal with veg and a cooked pudding with tea.
1900s the climate of NZ encouraged a lighter, less stodgy diet and recipes that involved game like deer and rabbit were needed.	1900s baking had begun to be a more lavish with such items as sponges, pikelets ginger kisses, afghans and gems.	1907 the famous cookery book Edmonds was published. Over 3 million copies have been sold.
1914-1918 First World War saw little shortage in food, in fact Britain was buying as much food and NZ could produce.	1918-1939 between the wars many factors occurred that saw a change in the NZ diet	1920 most homes were equipped with the first electric or gas ovens.
1930s  ladies afternoon tea parties were in full swing during the Depression as a cheaper alternative to dinner parties	.1930’s came the great depression – shortage in jobs meant people had little money to buy food. Soup kitchens were started and such dishes as the Shepherds Pie came about as a way to use leftovers	1935-1938 many continental refugees came to settle in NZ especially Dutch, Italians, Greeks and Jewish Refugees. They brought with them their national cuisine.

we made fish and chips, first i thought it was going to be terrible but it was good the chips were ok.

first we got some frozen fish, cut them into pieces, we got the chips seasoning and potato, we cut the potatoes into thin slices and cooked them, then we put seasoning while crumbing the fish. we cooked them in the oven 200 Celcius, 

we started with a piece of paper, where we wrote our ideas down and and gathered our thoughts on the piece of paper, after we finished our drawing on the pieces of paper we got a wood copy of a boomerang that was already cut out. We got the paint and drew our designs on the boomerang in pencil first then we painted it and it took me me two periods. I thought it was really fun and a switch up from what we normally donhjikl,./

Reason 1, because there could be an emergency

Reason 2, in case you don't have a calculator or need an app for work

Reason 3, it could be switched off, and only on when the teachers give permission

I think that phones should be allowed in class, if there's an emergency or parents or sibling are trying to get hold of you for a serious reason I think it's important to get in touch with them and or keep in touch with them if something is happening at home or in family lives.

If your in math class or any class I think it's important to have your phone if you might need to use the calculator or search something up on youtube or listen to music, which could benefit your learning if the class teacher doesn't have a calculator you could use your phone.

However, I think it's important that phones should be on silent in class so it doesn't interrupt the lesson and doesn't interrupt the students learning with all the buzzing and the beeping and the ringing.

The magnitude of the earth magnetic field at its surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss).



On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of the earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The magnetic field is extremely important to sustaining life on earth.


What would happen if the earths magnetic field disappeared? 
if the magnetic field weakens enough or temporarily disappears during the flip, then the earth could be hit with dangerous amounts of solar radiation and cosmic rays. The exposure could mean that more people develop cancer, Renne said, though there's no scientific proof this could happen.


how do we use the magnetic field?
Birds use earth magnetic fields sort of a heads-up display to help them navigate the globe. The earth magnetic field is a result of the movement or convection of liquid iron in the outer core. As the liquid metal in the outer core moves, it generates electric currents, which lead to a magnetic field.


earth magnetic field is, contrary to popular belief, is extremely weak, many times weaker than even a common Ferro-ceramic bar magnet. It's a strength at earth surface is roughly 25-65 microteslas, or 0.25-0.65 gauss, whereas a small bar magnet is around 10,000 microteslas or 100 gausses.


computer simulation of the earth field in a period of normal polarity between reversals. The lines represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and vertical. The dense clusters of lines are in the earth core.


while the north and south magnetic poles are usually located near the geographic poles, they slowly and continuously move over geological time scales, but sufficiently slowly for ordinary compasses to remain useful for navigation. the earth fields reverse and the north and south magnetic poles respectively, abruptly switch places. These reversals of the geomagnetic poles leave a record in rocks that are values to paleomagnetists in calculating geomagnetic fields, in the past such information, in turn, is helpful in studying the motions of continents  and ocean floors in the process of plate tectonics 

What did we learn?

So people in other cultures realise that different cultures do different things, if your in the same culture you might not be open to some of their choices and beliefs.

Stir fry

My profile was targeted at teenagers.

My recipe decision was based on getting all the different colours and protein and energy in the meal while also being really tasty, because teenagers tend to mainly eat junk food and not eat anything if it doesn’t taste good, so making something that’s healthy and tasty is good.

Why did i do this dish- personally i did it because its tasty and its easy, it doesnt take to much time. Its a pretty quick and fast meal on the go, only 10 minutes prep time, and about 15 minutes cooking time, it tastes good  and its pretty healthy for you.

The recipe to what i made in food tech- stir-fry

stir -fry teriyaki pork

Serves 4          prep minute time: 10 minutes    cook time : 15 minutes

400g pork mince

2 tsp minced ginger

2 cloves garlic, crushed

2 cups of carrots, broccoli, green beans and mini corn 

210 pouch of Watties Wok Creations

Teriyaki stir-fry sauce 

350 pkt of singapore noodles

 Total price= 26.40

Step 1 : roll pork mince into small balls, refrigerate for ten minutes

Step 2 : Heat a dash of oil in a wok or frying pan. Add the pork balls and brown over a medium to high heat for 5 minutes until cooked. Remove the pork from the pan and set aside.

Step 3 :Add the ginger and garlic to the pan and allow to sizzle – making sure it doesn’t burn. Add Wattie’s Frozen WOK Creations Chinese Style Vegetables and stir fry for 2 minutes.

Step 4 :Pour over Wattie's WOK Creations Teriyaki Sauce. Add Singapore noodles and toss to mix. Return the cooked pork balls to the pan. Continue cooking until the pork, noodles and vegetables are hot. Garnish with freshly chopped coriander.

i am making sherbet

making sherbet

aim: i want to making sherbet

method: First i got a sandwich bag, then gathered my ingredients on the science counter top, put 1 tbsp of raspberry raro and icing sugar. i then got a tsp of baking soda, citric acid and tartaric acid.

i sealed the bag closed and began shaking the bag to let all the dry ingredients mix into sherbet.

results: We dipped our finger into the sandwich bag which held the sherbet and tasted it, it was a bit bitter and the after taste wasn't that great.. it foamed in my mouth, which i didn't like very much but overall it tasted pretty good!

discussion: The reason the sherbet foamed in my mouth was the acids and the bases mixing with the saliva in my mouth, i would do it again, maybe not put as much of some products and put a bit more of others, or maybe some different flavours of sherbet next time.But i was also wondering why it didn't react in the bag???.. I was pretty confused in this situation, how could it react in my mouth but not in the bag? it still has all the same formula? the acids and bases are dry ingredients and don't react unless there is dissolved in water. all acids have the atom hydrogen, which dissolve in water, acid dissolves in water and bases in an acid opposite will remove the hydrogen from the acid when trying to dissolve which will cause the acids and bases to react with each other. on the other hand bases release hydroxide (OH-) ions when they are dissolved in water
