Sustainable Fishing

Sustainable Fishing

Is sustainable fishing even possible?

Yes, sustainable fishing could be possible but governments won't be willing to even take part in it because they are too busy with their most effective fishing vessels which can kill most of the ocean.

How is commercial fishing a threat to dolphins and birdlife (bycatch)?

It's because of their high-quality fishing vessels that are really effective and take out dolphins when they go by or wipe out the fish in the ocean which then resulting in the dolphins and sea birds hunger. 

Corrosion

 Aim: To investigate the factors that cause rusting in iron.

Method:

1. Label four test tubes. A - F and place in a test tube rack.

2. Test tube contents.

A = Iron nail and tap water

B = iron nail and oil

C = Iron nail and Nail Polish

D = Iron nail and salty water

E = Iron nail and calcium chloride sealed with a bung

F = Iron nail warped in aluminium.

3. Leave the test tubes undisturbed for at least three days.

Results: 

Discussion: 

An iron nail will corrode if it comes into contact with the environment and it would corrode quicker if it is in contact of water or salt this is why water and salt have the most rust. This can be stopped by blocking oxygen to the iron nail paint, grease or plastic will do to achieve this or you can coat it in other reactive metals such as zinc which are called galvanised.

Conclusion:

To make something rust it must be in the environment to do so that is why water has created the most rust while calcium chloride became the slowest and less reactive rust.

Shark finning

What is it?

Shark finning is an action where they cut the fins of sharks and put them back into the ocean leaving them dead. which fishermen and Asian people are responsible for this.

Why is it a delicacy?

people do this to make shark fin soup and food which they can sell for about $100. Most Asian people are responsible for this and they don't want people record of having cameras shown because they don't want people seeing what they have done.

How is this impacting our oceans?

This impacts our ocean because it disrupts the food chain as the king of the sea and with them going extinct the low predator fish overpopulate leaving the lower tier fish extinct which then kills the low predator fish.

The Starfish poem

The main message of this poem is to say that there is too many starfish away from the water that can't get back into the so the man makes a difference and chucks them back so everything you do does count.

"Good morning! What are you doing?" 

The young man paused, 

looked up and replied, 

"Throwing starfish in the ocean." 

"I guess I should have asked, 

why are you throwing starfish in the ocean?" 

"The sun is up and the tide is going out. 

And if I don't throw them in they'll die."

The Great Pacific Garbage Patch: Newspaper article

In social studies, we have been learning about the great pacific garbage patch. We have been learning about the microscopic plastic left from the rubbish in the ocean which then goes into animals and kills them showing why it has been bad for the environment lately.

This term we had to write about the great pacific garbage patch and the causes and effects of this all in a newspaper type of look.

Great Pacific Garbage Patch
5th May 2021	By Lincoln Choub
How much rubbish is in the ocean? 5.8 trillion pieces The numbers are staggering, There are 5.8 trillion pieces of plastic debris in the ocean. Of that mass, 269,000 tons float on the surface, while some four billion plastic microfibers per square kilometre litter the deep sea. What is The Great Pacific Garbage Patch? The Great Pacific Garbage Patch is the largest of the five offshore plastic/trash build up zones which are in the world's oceans. The build-up of trash is humongous increasing over time, which is of course the 1.5 to 2.41 million amounts of trash entering the ocean. This is located halfway between Hawaii and California where you can find heaps upon heaps of trash. Due to seasonal stuff, winds and currents the great pacific garbage patch location and shape are constantly changing. Only floating objects are the ones affected by currents and less by winds were likely to remain within the patch. How we found this is because people from around the world have either seen plastic in the ocean or people have studied the movements of it, you can see this all over the internet and why it happens. Why does this happen: This to humans using plastic in their lives which then results in them dumping it, making it go into the ocean. Also, when rain, wind, and floods fall on the land, these materials can carry plastic into the oceans. These objects are very lightweight and can be easily carried by the wind to the coast. The agency also identified five Asian nations as the biggest sources of plastic waste in the seas. What are the effects of this: Much like the microplastics we banned last year, other plastic gets dumped into the ocean. This litter then becomes toxic to wildlife. These effects are really damaging the ocean's ecosystem aquatic animals, marine animals, and pollution would kill the ocean. Also, toxic chemicals in plastic pollution can cause long-term damage to the environment. It can take up to a thousand years for plastic to break down. What can we do to help? We can do this by using less plastic in our lives which the government has done and sho has Mcdonalds they use paper straws instead of plastic straws while the government has reduced the plastic bags. We could reduce, reuse and recycle all help to cut down on the amount of waste we throw away. They conserve natural resources, landfill space and energy. Plus, the three R's save land and money that communities must use to dispose of waste in landfills.

Metals and Acids

 Aim: To show that hydrogen gas is produced when a metal reacts with acid.

Method: 

1. Light your bunsen burner.

2. Add your sample of metal to your test tube. Add 3 mL of acid.

3. Carefully invert the boiling tube above the test tube containing the metal and acid.

Results: The liquid started to bubble when the metal was dissolving which made a pop sound with the hydrogen gas.

Discussion: This happened because while the metal was dissolving in the acid it was making hydrogen gas we knew this because the test tube was fizzing/bubbling and getting more heated which then was being trapped inside the test tube, and then after using the splinter which was on fire on the hydrogen gas it resulting in a pop sound.

Conclusion: This can say that hydrogen gas can be produced when a metal reacts with an acid which can make a loud pop sound when it reacts with fire.

What are we learning and why?

We are learning about HART and why they protested against and all rugby tours to and from South Africa.

How did we learn it?

Researching websites to get our info I was very full of knowledge.

I don't have any questions.
