Solar and Lunar Eclipse

      What is the difference between Solar and Lunar eclipses? 

Solar Eclipse:

Solar eclipse happen when the moon blocked the light from the sun. We see darkness and light glowing around the edge of the earth. 1965 was the last time Solar Eclipse happen in New Zealand. The next solar eclipse in New Zealand will be in 2028 on Saturday.

Lunar Eclipse:

A lunar eclipse happens when the moon passes through the earth shadow. During the Lunar eclipse, we don't see the moon at all. 1965 was the last Lunar eclipse in New Zealand. The next lunar eclipse is on Fri, Nov 19, 2021, at 8:29 pm.

Earth Science - Volcano

 Mayon Volcano

 Aim: To create a volcano and erupt them.

Method: We used scrap cardboard and Tristan brought a 1 Litre bottle. We then glue the bottle into the cardboard. After that we cover the bottle with Newspaper, forming the look of Mayon Volcano. On the second day of science after the glue had dried, we then painted our volcano maroon as the first coat. After few minutes the maroon paint had dried, and we now coloured it with green as the final coat. 

Research: Mayon Volcano is located in Albay, Philippines. It is called to be the world's most perfect volcanic cone because of the symmetry of its shape, it has a base 80 miles (130 km) in circumference and rises to 8,077 feet (2,462 metres) from the shores of Albay Gulf. The most recent eruptive episode began in early January 2018 that consisted of phreatic explosions, steam-and-ash plumes, lava fountaining, and pyroclastic flows. It was reported that the 2000 eruption displaced 14,114 families and damaged at least ₱89-million worth of property and crops. The myth of the creation of Mayon Volcano is as heated as the heart of the peak itself, with a plot involving star-crossed lovers, and a tragic ending leading to the rise of the jewel of Albay. Legend has it that a beautiful maiden, Magayon, lived in a place called.

Discuss: The way volcanoes form is when one tectonic plate moves under another. Normally, thin heavy oceanic plates move under a more concentrated continental plate. When there is enough magma builds up in the magma chamber, it will then forces its way up to the surface and erupt, causing volcanic eruptions. The difference between Magma and lava is Magma is an extremely hot liquid and semi-liquid rock the can be found under the Earth's surface. If the magma flows onto earth it will then be called lava. 

Conclusion: Yes, our volcano science work. The eruption went up pretty high up and came down steaming. Maybe next time we will not make it super concentrated just to make it look like real lava.

Science - Ecosystem Project

 Ecosystem Project

During science time, we have been investigating Habitats, ecosystems and the animals/plants that live in them. My group has decided to create a forest ecosystem. That have trees, rocks and bushes. The animals we have made are a rat, pterodactyl and a rabbit.

Dozens of various rats inhabit many different habitats and ecosystems. Because we are creating a forest ecosystem the rat shown is brown. Brown rats are the most common in the forest. 

Pterodactyls are carnivores meaning they only eat meat. Pterodactyls were believed to eat fish and small animals. So a rabbit and a rat would be the ideal food source for a pterodactyl to eat. In our ecosystem, the pterodactyl would be the predator while the rat and rabbit would be the prey.

Here are some pictures:

Leak-Proof Bag

 

Aim: To stop water from leaking out of the bag. 

Equipment:

• Sandwich bag
• A lot of pencils 

Method: 

1. Fill the sandwich bag with water about halfway.
2. Poke the Sandwich bag from one side to another.

Result:

 Discussion: 

A lot of plastic is flexible because they are made with polymer chains. As you poke the pencil through the bag, all the molecules in the polymer chains ( A polymer is a substance in which contain a large molecule that is formed with many repeating subunits.)  will surround the pencil, sealing the hole tightly and preventing leaks. If you remove the pencil, all the molecules don't move to seal the hole, which will then allow the waters to escape from the bag.

 Conclusion: Did it work? Would you do anything differently

The experiment that I did actually work, The only thing that I would try next time is to fill the bag fully up and see how many pencils it can take until the water escape.

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.
