Stars

Kia Ora bloggers and viewers!

Today I will be sharing some astonishing facts about the stars. I found it quite confusing to learn about the stars because I dont really know there role in the sky or what they’re even made of.

It was really fun to learn what a shooting star is really made of.

Here are some interesting facts, I hope you learn something new!

Star facts

1. Did you know that the sun is actually not the biggest star? There are way bigger stars than the sun, in the constellation Orion, on his knee is a blue super giant star called Rigel. This star is 2 times hotter and x70 bigger!

2. The stars have different colours, blue, white, red and orange. Did you know that the blue stars are the hottest stars and the red stars are the coolest! A good example is when using a gas stove the blue fire is hotter than the orange\red fire.

3. Did you know that the stars are made of helium and hydrogen just like the sun.

4. The Proxima Centauri is the closest star to the sun and this star is a red dwarf.

5. The stars can have different sizes and colours which is why they are called “red dwarfs” or “blue supergiants”.

 

Shooting star facts

1. Shooting stars aren’t actually stars because stars are made of gasses which means it cant be a falling rock.

2. Shooting stars are actually small particles of a comet, asteroid or a meteoroid that shoots down into Earth’s atmosphere.

3. Earths gravitational force pulls the particles and they go through Earths atmosphere.

4. In some cases the particle can turn into dust. In other cases they can turn into a fireball and shower down on Earth called a meteor shower.

 

 

 

 

 

 

The Sun facts

The Sun

Kia Ora!

Today our class had to research through websites about the sun. It was very easy to do, the fun part was adding all the pictures.

I found it a bit hard to find some interesting facts  about the sun with limited websites.

I made a slideshow answering some questions, I really hope you all learn something new!

 

Gravity explanation

Kia Ora!

Today my class had to write explanations about gravity.

It was hard to have ideas about gravity since I don’t know much.

It was very fun to write paragraphs of how gravity makes a huge impact on our life’s.

Here is my explanation I hope you learn something!

 Do you wonder if there is gravity anywhere in space?

What is gravity?

I will tell you what gravity is, who discovered gravity and what gravity does for us. Gravity is something that draws all objects, creatures and everything to earth including us. It’s something in the earth that sticks us to the ground. Some scientists think that the black hole in the centre of the Milky way is the cause of gravity.

 

Who discovered gravity? 

There is a person who discovered gravity 300 years ago, his name was Isaac Newton. He was just sitting under an apple tree, when an apple fell on him. He thought of why things fall down and never stay up? He researched until he found out that everything that goes up will always go down because we have gravity.

 

What does gravity do for us?

Gravity makes us stay on the ground. The gravity on earth pulls us towards the centre. There is no gravity in space, that is why no one can survive in space without special suits. That is the reason why we walk with our feet on the ground and the reason we carry our weight, however if earth didn’t have gravity all objects would be up in space orbiting forever. I wonder if there is gravity anywhere in space? If there was no gravity nothing would be on the ground.

Conclusion

I learnt that nothing that goes in the sky stays there because of gravity. I find it cool how gravity pulls us to the center of the earth. I think that gravity is really important because everything would be floating, including us.
