Esol - Water pollution

                      Water is life, take care of it!

We cant drink water. Water pollution is a serious environmental issue. Water is said to be polluted if its physical, biological, and chemical properties are deteriorated via anthropogenic and natural activities. water pollution has impacted humans and animals in all aspects. It is hazardous to the environment. 

What is water pollution? The water we drink daily usually looks clean; however, it is contaminated with microscopic pollutants. In New Zealand, it is a big problem because there is a lot of farmlands and rural areas. Animals on farms poo everywhere and it goes down into the soil and finds its way into the ocean and sea. However, we cannot do anything to it because farming is one of the main businesses in NZ. It has been the NZ backbone for the economy.           

Science

Copper Coin Experiment

First, we cleaned our Coins in Salt and vinegar solution. Then we put 50ml of 2mol+ Naoh into a beaker. We heated the beaker on the bunsen burner and stir as heating and then take off the heat. We added a spatula of Zinc powder and heat lightly for 30 min with the coin inside and stir as heating. Then we take the coin out with the scissor tongs. After that, we rinse the coin under water to remove chunks of zinc and the last thing we did was wave the coin in the blue flame using tongs and the coin turned to gold. And that was the end of the experiment

The periodic table

what are the different types of elements? metals, non-metals, and gasses

What are the transition metals? The 38 elements in groups 3 through 12 of the periodic table are called "transition metals". 

What are Alkali metals? any of the elements lithium, sodium, potassium, rubidium, caesium, and francium, occupying Group IA (1) of the periodic table. They are very reactive, electropositive, monovalent metals forming strongly alkaline hydroxides.

what are noble gasses? any of the gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 0 (18) of the periodic table. They were long believed to be totally unreactive but compounds of xenon, krypton, and radon are now known.

A fact about the periodic table - The only letter not in the periodic table is J

English - Learning Facts

Today I learned five new facts about five different topics.

Usain  Bolt is the fastest man on the planet.
The shortest player to ever play basketball was  Mugsy  Bogues.

Acid Rain Experiment: Science

What is Acid Rain? Acid rain is a rain or any other form of precipitation that is unusually acidic.

How does it form? Acid rain is caused by a chemical reaction that begins when compound like sulfur
dioxide and nitrogen oxides are released into the air.

Why does acid rain matter? because acid rain cause pollution and pollution cause disease



Method:
1. set up petri dish
 -Add a few drops of water to these.

2.Add 1 spatula of sodium sulfide to weigh boat
-take photo

3.Add 5 drops of sulfuric acid and quickly put lid on

4.watch and take photos

                                         

                                         






























observations -
The blue litmus paper turned red
The Bromothymol blue change to blue to dark dark green/blue/yellow

Hamburgers:

Colour - The hamburger had a little bit of color from the tomatoes, lettuce and the cheese

Flavor - The  meat had a lot of seasoning and the tomatoes and lettuce were juicy

Texture - The meat was crispy, the pickle was crunchy and the tomatoes were soft  

Rice burgers:

Colour - The rice burger had a lot of colors from the tomatoes, lettuce, pickle, and cheese

Flavor - The meat had a lot of seasoning, the rice was soft and had a good flavor and the tomatoes and lettuce were juicy

Texture - The rice was soft, the burger was crispy, tomatoes and lettuce were juicy and pickle was crunchy  

Social studies - Child Soldiers

In social studies we have been learning about child slavery, child soldiers and child labour. We had to choose between  this topic and I selected child soldiers.All the information about child soldiers is in the slides below.

 

Social studies

We have been learning about slavery in social studies.This is a research task we did on Harriet Tubman. 

Maths

 What does it mean to be a good mathematician?

As students build their mathematical proficiency, they become more confident  to learn and use math. And anyone who has great skills is also a good mathematician even if they do other jobs. 

Social studies - Human Rights

This year so far in social studies we have been learning about Human rights.

This is the declaration of human rights which the whole world came up with.

science - Bones

Bones

What are bones.?   Bone is the substance that forms the skeleton of the body.  Muscles pull against bones to make the body move. Bone marrow, the soft, spongy tissue in the center of many  bones, makes and stores blood cells.

How does our body make them.? 

Bones kinda do have a similar life cycle as a living being. They start as cartilage that is like a plastic/rubber padding. As a young life form is being born by in a mammal or a mother’s womb. The skeletal system begins to form a framework of cartilage. Before birth, there is a certain amount of hardening of bones/limb bones to allow the human being to somewhat stand properly after a few months or so on. Even so, the greater part of a skeleton framework is cartilage at birth. After birth, the bones or cartilage in the skeleton begins to harden. The continues throughout life forms life until old age, a small amount of cartilage is left and bones are now old and brittle. Also, the process of hardening is called ossification. 

- Ossification/ Hardening is a process of adding new bone materials/cells called osteoblasts.

How do they grow/repair.?

Bones grow and are repaired by the process of getting elderly. Bones also repair themselves naturally. Here’s how bones heal:

1. Immediately after a fracture occurs, a blood clot and callus form around it.

2. New threads “threads” of bone cells start to grow on both sides of the fracture line toward another. 

3. Eventually, the fractures close up and the callus is absorbed by the new cells. This process may take from six weeks to a year.

Bones grow and get healthy with the help of Calcium, Iron, Vitamin D, Protein, and fluoride.
