Street Art

 In art class we had to pick your favourite piece of art from a bunch of different photos. The picture that I chose was a samurai that had his swords out. One of the reasons I picked this piece of art was because of the art style that it has, the art style is like a anime type of art style and it just looks pretty cool

This is my Sustainable Fishing prezi that we have been working on for a while

Pros and Cons of over fishing

Pros: Over fishing has a good list of pros and cons to it and here is the pros, over fishing can make more jobs available to people who are in need of jobs. Another pro is that over fishing helps boost the economy, this is because there has been a demand for seafood in the last few decades and when over fishing that means that there is more income. Some companies that over fish have a replenish system so that they can balance things out.

Cons: A massive problem is that over fishing can cause a decrease in marine life population, yes there are some replenishment systems but some of them aren't immediate and they don't take action right away. Disrupts the Eco system, the reason for this is because over fishing disrupts the food chain and that means some species have to adapt because there source of food isn't there anymore. It can also increase garbage population because of the garbage coming from the ships

Pink Shirt Day

What is pink shirt day?

Pink shirt day is a day where people spread awareness about bullying. This day originated in Canada in 2007. There is multiple things that you can do in a bullying situation. The first thing that you can do is be a bystander, being a bystander is when you witness a situation with bullying however you don't do anything to intervene. The second thing that you can do is be a out stander, being an out stander means that if you see a situation that involves bullying you try and do something to either stop it or get someone like a teacher to stop it. In my opinion I am more of a bystander rather than an out stander. I also think that raising awareness for this is great because bullying happens a lot in school and in workplaces.

Shark Finning

Shark Finning 

What is shark finning?

Shark finning is a delicacy in Hong Kong and China, shark finning is where some people will take a shark, cut the fins off and then dump them back in the ocean for them to die a long and painful death. It is said that shark finn soup has barely and taste too it, no nutritional value and they have to add some sort of broth to actually give it a taste. Keep in mind that the cost for this soup will be $140 New Zealand price. Sharks only kill around 10 humans every year however humans are killing 30,000 sharks every hour just for there finns. A lot of the companies that do shark finning are illegal, they won't let any cameras in the shops because they dont want to get exposed for what they do. A lot of the shark finns will be sold on the black market because that is the only way to see it.

Why is it a delicacy?

The reason for this being a delicacy is because people have been having this soup for 1,000 years. Back in the days people believed that it had medical benefits and they also thought of it as a massive victory over powerful sharks.

How is this impacting our oceans?

There is many reasons for this effecting our oceans and marine life. The first reason is how it can lead to animals going extinct, think of it like this Sharks are at the top of the food chain named level 1. If we wipe out level 1, level 2 starts to overpopulate because they have no predators. Level 2 then feeds on all the lower levels until the lower levels go extinct leaving the level 2 animals to starve to death. The next reason is that all the coral reefs that are beautiful will turn to a massive swamp lands due too less herbivores feeding on the algae on the bottom of the ocean. 

The Starfish Poem

What is the main message of this poem?

The message relates too plastic in the ocean, if you stop using plastic you are doing the best that you can do to save sealife. This relates to the poem where the boy is trying to save as many starfish that he can. Although it may not make a massive difference it made a difference for that one starfish or that one life in the ocean. This also relates to us in the fact that sometimes we ourselves may need a little bit  of help sometimes

Give evidence for this?

We see evidence of this when the young man says "It made a difference for that one" or when he says "Throwing starfish in the ocean". 

Testing for carbon dioxide gas

Aim: To show that carbon dioxide gas is produced when a metal carbonate reacts with acid.

Equipment: Two boiling tubes, delivery tube and bung, bunsen burner, test tube rack, wooden splint, a bottle of acid, small amount of metal carbonate, test tube tongs, safety glasses.

Method: 

1. Light your bunsen burner 

2. Add a pea sized amount of metal carbonate into one of the boiling tubes.

3. Place this boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready.

4. Add 5ml of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube.

5. Holding the other boiling tube with your tongs, capture the gas produced as shown in the diagram below.

Results: The one that had the most rust was the tube that had water in it and the one that had the least amount of rust was the one wrapped in aluminuim. 

Conclusion: In conclusion the water tube turned out as expected and a lot of the other ones didnt have that much rust at all such as the nail polish and the aluminuim.
