News Article - Eastern Pacific Problem

Hi, Today in our social studies we are writing  news article outlining the problem in the Eastern Pacific Ocean.  

The problem in Eastern Pacific is debris trapped in the Great pacific Garbage Patch and it is harmful to the marine life. It is harmful to the marine life because when marine animals think it's a food they will eat it and plastics take about 500+ years to breakdown, it will stay in their stomach and make them suffer until they die, also plastics contain chemicals.

Plastics dump are becoming more and more problem, lots of whales are and getting end up on shores with full of plastics in their body. Whale  when they go up to the fertilises phytoplankton when they go sea surface, phytoplankton are very important because it absorbs carbon dioxide and tuns it into oxygen, also it's 4x more than Amazon Rain forest can produce.

How do the plastics get trapped in the Pacific garbage path?

Plastics litter get through the water ways and getting end up to the ocean, then gets through the ocean current and that leads to the garbage patch.

Action	Cause	Effect
Daily use of Plastic	Plastic stacking up	Waste and can bring problem to the environment.
Littering	People are to lazy, bins too far away.	Rubbish getting through the water ways and ending up to the ocean.
Tons of rubbish going into the oceans	Not a lot of bins around.	Animals dying, because they think its a food.
Companies selling zero-waste products
Provide an example of GOVERNMENT CONTROL Banning plastics bags  More rubbish bins around		Less problem for the environment and less animals dying.

Lime Water Test / Unfinished Work

Testing for Carbon Dioxide Gas

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

Equipment: Two boiling tube, 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 the metal carbonate into one of the boiling tubes.

3. 

4.

5.

6.

7.

8.

Testing for the Presence of Oxygen

 Aim: To carry out a test for the presence of oxygen gas.

Equipment: A pea-sized amount of manganese dioxide, boiling tube, bottle of hydrogen peroxide, safety glasses, wooden splint, Bunsen burner and a test tube rack.

Method:

1.  Light your Bunsen burner.

2.  Add the manganese dioxide to the boiling tube and place it in your test tube rack.

3.  Add 2ml of hydrogen peroxide.

4. Light  a splint and let it burn for a while.

5. Blow the splint out and insert the glowing embers into the mouth of the boiling tube.

Observation: When we inserted the splint embers into the boiling tube it re-light the splint. It re-light because there was oxygen being produced by hydrogen peroxide and manganese peroxide. 

Trashing our Planet | Social Studies

 Today I am going to make a new blog-post about what we are learning in my social studies. So far we have been learning about the ocean plastic pollution, we looked at Happy broadcast which is a news channel that only has positive news. We watched a few videos about people telling us what is happening in the ocean and we answered some questions about it. 

What does plastic pollution do to our ocean? Plastics are bringing more problems to the ocean and for the marine life, plastics take 500 or more years to break down. Also plastics breakdown to small-tiny pieces called micro-plastics. Micro plastics is bad and dangerous because of the chemicals in it and if it is ingested by a marine animals it can block digestive tracts.

How can we help?/What is something you could do to reduce what goes in your red bins? To reduce what goes in your red bins you should put the right trash in the right bins, recyclable items should go to yellow bin, food compost should go in the green bin and non recyclable or organic goes in the red bin.

Metals and Oxygen

 Last week we did we did another experiment it was about making a metal oxide and Today I will be talking about it.

Aim: To make a metal oxide and observe the difference in properties of the product commpared to the reactants.

Equipment: A piece of magnesium, Bunsen burner, safety glasses and metal scissor tongs.

Method:

1. Light your Bunsen burner.

2. Hold your piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip of the              magnesium.

3.  Place the other end of the magnesium into the Bunsen flame ( at the top of the blue flame).

4.  When the magnesium begins to burn,  do not look directly at it, as the light emitted can permanently           damage your eyes.

Observations: The magnesium got very bright when it was burning and became like a powder/ash when it stopped.

Metal Reaction

 Today in our Science class we did an experiment about metal and how it reacts to acid. 

Equipment:

• Test tube
• Boiling tube
• Piece of Metal / Magnesium
• Acid 
• Wooden splint 
• Bunsen Burner 

The first thing we did was to put 2ml of acid in our test tube, then we dropped a piece of magnesium in the test tube ad covered it with the boiling tube to trap the gas being produced. After a minute we burned our wooden splint and took the boiling tube filled with gas and we sticked the burning splint inside and it pop.
