Making a drill gauge

Today in Metal, our job was to make a drill gauge. We are not yet close to finishing it since we have just started making it today. The first few steps that I did was marked 115mm in the 20 by 3 miles steel flat bar. I then mark a straight line using a ruler and a Sciber. Once that was done I cut it where the mark was with a hacksaw. Afterwards I smooten the edges with a file. 

Here is how my Metal look:

Social Study - Racism

This week on social study we have learned about what is Racism in NZ. There is an article about a Muslim girl that is named Zeinab's. She was once shy about his culture and then when the mosque shooting happens she has realised that she doesn't need to be shy about it. She had realise that she need to be more proud of her own culture. 

This is the words that she said when she became proud of her own culture:

Today, instead of straightening away my brown frizzy curls I will embrace them. 

Instead of shying away from my family when they speak Arabic loudly in public, I will join them. 

Instead of saying no to someone when they ask ”say something in your language,” I will say it. 

Instead of telling my mum to make English food when my friends come over for dinner, I will ask her to make all the Arabic dishes she can think of. 

Instead of denying the roots of my name, I will admit that they are Muslim, I will tell you I was born a Muslim, and I will tell you that no matter if I identify as it or not, I will still die a Muslim. 

Today, I will join my mum as she reads the Quran, as she prays to Allah for the people who lost their lives, the people injured, and the people hurting.

Great Depression

 Why was Germany hit the hardest during the Great Depression? Germany was hit the hardest during the Great Depression because of the major factor, the Treaty of Versailles. It was supposed to settle outstanding disputes following the cessation of hostilities in World War I.  Germany reeled from the huge burden of reparations payments required of it as a condition of the treaty.

Explain what Germany had to agree to by signing the Treaty of Versailles? The three agreements of The Treaty required Germany to disarm, make ample territorial concessions, and pay reparations to certain countries that had formed the Entente powers. 

How was Aotearoa affected by The Great Depression? In New Zealand, the effects of the crash were not immediately apparent. But from 1930 export prices began to plummet, falling 45% by 1933. To a country overwhelmingly dependent on agricultural exports, this was devastating. Demand for their goods and services fell, as did the prices they charged.

DNA Extraction

 Aim: Finding DNA in a kiwi fruit

Method: 

1. Mush half a kiwi fruit in a zip lock bag with a splash of water and a small teaspoon of salt. 
2. Strain the solution through a cloth into a beaker.
3. Add a squirt of dishwashing liquid and stir.
4. Pour into a test tube.
5. Place the test tube in a beaker filled with WARM water.
6. Slowly pour 5mL of methylated spirits down the side of the test tube.  

Results: 

Discussion:

DNA is found in the cell nucleus but some DNA is also found in the mitochondria, Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Most DNA is made up of simple repeating units called nucleotides. The DNA molecule is described as a double helix but is sometimes also called a twisted ladder that is made with base, sugar and phosphate. 

Conclusion: Did it work? Would you do anything differently? Our experiments work really well because we have found the DNA  In a kiwi fruit. One thing that we might change is to put less water so that it will give us more DNA to take out.
