The Sun

 the sun
The Sun or Sol, is the star at the centre of our solar system and is responsible for the Earth’s climate and weather. The Sun is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. The average radius of the Sun is 695,508 km (109.2 x that of the Earth) of which 20–25% is the core.

Star Profile
Age: 4.6 Billion Years
Type: Yellow Dwarf (G2V)
Diameter: 1,392,684 km
Circumference at Equator: 4,370,005.6 km
Mass: 1,989,100,000,000,000,000,000 billion kg (333,060 x Earth)
Surface Temperature: 5500 °C



Facts About The Sun
One million Earth's could fit inside the Sun:
If a hollow Sun was filled up with spherical Earth's then around 960,000 would fit inside. On the other hand if these Earth's were squished inside with no wasted space then around 1,300,000 would fit inside. The Sun’s surface area is 11,990 times that of the Earth’s.

Eventually, the Sun will consume the Earth:
When all the Hydrogen has been burned, the Sun will continue for about 130 million more years, burning Helium, during which time it will expand to the point that it will engulf Mercury and Venus and the Earth. At this stage it will have become a red giant

The Sun will one day be about the size of Earth:
After its red giant phase, the Sun will collapse, retaining its enormous mass, but containing the approximate volume of our planet. When this happens, it will be called a white dwarf.

The Sun contains 99.86% of the mass in the Solar System:
The mass of the Sun is approximately 330,000 times greater than that of Earth. It is almost three quarters Hydrogen, whilst most of the remaining mass is Helium.

The Sun is middle-aged:
At around 4.5 billion years old, the Sun has already burned off about half of its store of Hydrogen. It has enough left to continue to burn Hydrogen for approximately another 5 billion years. The Sun is currently a type of star known as a Yellow Dwarf
The temperature inside the Sun can reach 15 million degrees Celsius:
At the Sun’s core, energy is generated by nuclear fusion, as Hydrogen converts to Helium. Because hot objects generally expand, the Sun would explode like a giant bomb if it weren’t for its enormous gravitational force.

The Sun generates solar wind:
This is a stream of charged particles, which travels through the Solar System at approximately 450 kilometres per second. Solar wind occurs where the magnetic field of the Sun extends into space instead of following its surface.

Archimedes's "Eurika" moment

 Archimedes invented, or people say he invented, a bunch of different kinds of machines. The most important of these machines was the screw pump, which uses a screw to lift water from one place to another.

  I am going to talk about the "Eurika" moment and what he did. At that time he lived in Greece Syracuse, and the king  gave somebody a peace of gold to make him a crown. After a couple of days that person gave the crown and the gold that was left to the king. The king thought that  that guy stole some of the gold left over, so he called Archimedes. When Archimedes arrived  he couldn't find out if that guy had stolen any gold.

 One day when Archimedes was in the bath he saw that when you get in water or any other material that some of the water goes out because any object such as a rock if i put it in a jar full of water then some of that water will go out. So he was in the bath and when he saw that he shouted, Eurika! (I found it) And ran to tell the idea to the king. Archimedes and the king discovered that the guy that had made the crown for the king also stole some of that gold. And that was the story of Archimedes's "Eurika" moment.

My Introduction

Hope you liked this introduction because I am going to do more videos for games and if you want, in the comments tell me if you want, I will make videos for stop-frame animation like my introduction.

The music was from Nordic Giants and the song is called shine, check them out on YouTube.

The Potion

   The sheep were running around,falling off the edge of the hill. I was trying to put all of the sheep in their pens by waving my arms around and yelling at them, while Pat the dog was laying down and licking his bone.

   When dad came back from the market he screamed at me because the sheep were all over the place. I don't like when dad shouts at me when it's not my fault. Well, that was enough because this time dad grounded me for something that I didn't do.

   So I thought of a great idea, what if I make a potion for that big old bag of meat, Pat into something helpful. 

  Today I woke up, I ran down the stairs, I grabbed the saucepan and ran to the bathroom.

I'll put some shampoo maybe even a packet full. 
I'll put some toothpaste and some oxygenated water 3%, for sure 
I think I'm missing something, 
something very important, 
I think I am missing some shaving foam.

  Okay I have what I want from the bathroom, now let's go to the kitchen.

I'll put some tea and biscuits
I'll put some milk too, 
I'll put a packet of coffee not too strong. 
Hey, I forgot about the ham and the cheese

  That was fun. Now let's cook it. So I put the saucepan on the gas ring to cook the mixture. While the mixture was boiling some red, blue, green and yellow smoke was coming out and it made me float above the ground and it made me say things like milky cow, porky pig and stuff like that. When all that finished I went outside to give it to Pat. When I gave a spoonful of that mixture Pat started to run around me and he jumped up and down. When that finished he wasn't a big fat dog but he was a great thin and smart dog. 'Yes, it worked,' I said.
'What worked?' Pat asked.
'You can talk!' I said.
'Of course I can talk. I can even fly,' Pat said.

'What?' I screamed. 'Can you help me by putting all the sheep in their pen?'
'Yes, Marley.' So Pat put all of the sheep in their pens. When dad came back from work he thanked me and I said 'I didn't do it.'

'Really, Then who did it?' Dad said.
'I did it,' Pat said.
'What! That's impossible.' Dad said.' How did you do it?'
'I just put sum stuff together, cooked them and gave a spoonful to Pat.'
'Wow that's amazing.' Dad said and we went back home.
