How To Navigate Using The Stars!

In our science class, we have been working on explanation writing and have been working on not to plagiarise (Not copy and pasting). So our topic was to explain how Stars can be used to navigate. 

So our challenge is to explain how the first Seafarers navigate the ocean using the Stars, and how navigators navigate using the Stars. We really had to be careful not to plagiarise when reading an article, because it can cause us in big, big trouble, like going to jail or the court. We also had been practising this because when we go to University we are not allowed to copy an article. Our challenge was to add a lot of paragraphs to our explanation writing and explain how navigators navigate using the Stars. And we had to put the conclusion at the end and a summary. And we need to remember to add a title and a rhetorical question.

It was very fun and challenge to write our explanation writing because we had to put sentences to our own words. I really like this session because I learned something new too. But I felt really proud because I completed my work and put sentences in my own words. 

Here is my work:

How to locate the ocean using the Stars. 

How did the Navigators navigate the oceans by using the stars?

I'm going to tell you how navigators navigate the ocean using the Stars. And I will explain how Stars can be used to navigate Space. The purpose of this explanation is to tell you how navigators used their own knowledge to navigate the ocean using the Stars. Also how important and special the Stars are to navigate different things. 

So first let  me explain to you the constellation, there are 6 different constellations and they are Ursa Major, Ursa Minor. Cassiopeia, Orion, Crux and Centaurus. The constellations have descriptions and are different, therefore it has different hemispheres and they are the Northern hemisphere and the Southern hemisphere. The Ursa Major is described as a big dipper it is commonly found in the northern hemisphere, Ursa Minor describes as little dipper and it’s in the Northern hemisphere, Orion can be found in the Northern Hemisphere and it is describe as a Hunter, Crux describes as a Cross and it’s easily found in the southern hemisphere and the Centaurus can be located in the Southern Hemisphere which describes as a Centaur. 

Now let me inform you how the navigators find their way to navigate the ocean using the Stars. So the navigators directed their canoes to the sparkly beautiful star on the horizon and used a star compass. Then when the star increased up to the sky, that’s when the navigators chose a different star. And then they do those steps continuously as the night goes on. Navigators navigate the stars throughout the night and stop until they navigate twelve Stars. There were things that also helped them to navigate the ocean and it was the Moon, Jupiter and Venus. And then the navigators wrote the spot of where the Canoe is between the sun. And the navigators glanced and focused on the sun to its destination in the evening. 

Now let me teach you how the Stars can be used to navigate. But first I will teach you how you can navigate using the Stars in the northern hemisphere. To start with you have to find the North Star/Polaris. It’s a special and an important Star because it’s the only Star that doesn’t even move, while the rest of the Stars move around it. To find the North Star you have to find the Ursa Minor or the Little dipper. The North Star/Polaris is placed on the tip of the handle of the Ursa Minor. But if it’s too difficult for you to find Ursa Minor you could look for the Ursa Major which is called the Big dipper. If you found the Big dipper you could use its two Stars at the end, they are called the Dubhe and Merak. And then direct it to the North Star/Polaris. If there are objects interfering with the North Star and the little dipper you could always remember that the distance between Dubhe and Merak is 5 lengths long to the North Star. 

Now let me tell you how you can navigate using the Stars in the Southern hemisphere. First of all the Southern hemisphere doesn’t have the North Star which you have to find the Southern Cross/Crux. If you're having difficulty to find the Crux then you should find the two bright stars beside the Crux, they are the pointer Stars. The pointer Stars will help you alot and should lead straight to the Crux. After you’ve done those steps you could now draw a straight line where the tip of the Crux is pointing. And between the pointer Stars you should measure the line properly, going down in the same direction as the Crux. And then use the two lines straight down to the horizon, and now it should be pointing at the South. 

I hope you learned something new and got information about navigating using the Stars. Hopefully by now you should be able to have the information of how the first seafarers navigate the ocean using their vision and the Stars. And if you want to navigate the northern hemisphere the key is to find the North Star/Polaris. But if you live in the Southern Hemisphere you need to locate the Crux to navigate the Southern hemisphere.

Types Of Communication | Hur 3

 Hello readers, In our Science class with a different teacher, we have been learning on explanation writing. And the explanation writing is about communication in life and in space. 

The challenge was to research all the following five-question and answer them. And make a presentation for the answers. I had to go to different websites to know the answers because all the question were interesting. The questions were : 

What are some ways to communicate? (Pick 3) 

How do these forms of communication work, what do they rely on or use? 

Why can nobody hear you shout in space? 

Is radio communication instant? 

What does this mean for space mission from Earth to Mars? 

I did my presentation on renderforest because it was easy to use, but there was some technical difficulty. I only answered the first questions and had three communication explanation. Because the Renderforest has a limit of how much slides I can put in and how much words I can add. Each slide had a limit of how much words you can put it. So I hope you can understand each slide. But the rest of the questions I put them in my google docs. I really had a hard time making the presentation but I had fun researching the questions and answering them. 

I hope you can enjoy my presentation and can understand it, so here it is: 

How does these forms of communication work?

The forms of communication pass through sources and the receiver. It transfers the understanding and the information from one person to another person to communicate. They are made up of four key components to process communication. They are encoding, medium of transmission, decoding and feedback. That’s how the sender and the receiver communicate. 

Why can nobody hear you shout in space?

Nobody can hear you shout in space because the sound waves are carried by air molecules hitting each other and the microphone. So the little pressure drops are the purpose of carrying the sounds. If the molecules decrease and hit the microphone they hear a quieter communication. In space there is no air so you can’t shout in space, that’s why the sound can’t travel to one and another.

Is the radio communication instant? 

Radio communication travels very quickly in space, they are electromagnetic radiation, they travel at the speed of the light. The speed of the light is approximately 300,000 kilometres per seconds. The radio receives radio waves and turns them into speakers and creates sound waves. There are two types of radio communication : AM (amplitude modulation) and FM (frequency modulation). The other radio is a technology that allows one another to keep contact with. The radio receiver gets the audio and data sent over to the radio waves. 

What does this mean for a space mission from Earth to Mars? 

When travelling from Earth to Mars it would take about 21 months. To get to Mars it would take about 9 months and stay in Mars for 3 months and come back to Earth. There are three steps of travelling to Mars from Earth which take a very long time, so you have to be patient. Earth and Mars orbit are not in perfect circles, Astronauts can travel from Earth to Mars when the orbits are at the same distance. It needs to be at the right timing or otherwise the rocket ship won’t be successful to get to Mars. You really need a lot of fuel to travel to Mars from Earth. 

Question of the day: What is the best website to do your presentation?

Navigation in space | Challenge

 Welcome back bloggers, In today's blog post I will be sharing you the finished work that I have been working on in Science. It has been fun in the science room during this term, we had been doing fun stuff and learning a lot. 

So our topic is about navigation in space. Our challenge is to answer all the following question that our Science teacher put for us to answer. So we had to research deeply and in a detailed way so that we know the answer to each question. We had five questions to answer and a bonus one about the Black Hole. And we can answer the questions in a slide or straight in the blog post. I prefer to answer the questions in a slide so I can add some details to it. It was so fun to answer all the questions and complete the challenge. I felt really proud of myself because I answered all the questions and presented it on the slide, and published it on my blog. 

Hope you enjoy my presentation, so here it is the link to my slideshow:

Knowledge about | Gold mining & Discrimination

 Hello viewers, in this blog post I will do one of my reading tasks. My reading task is to share all the things I know about gold mining. This is my own opinion about gold mining and discrimination, I don't know what gold mining and discrimination really mean, so I will try my best. 

Next week I will make a blog post of what I learned about gold mining and discrimination. I will share you all my knowledge and what they actually mean. 

The things I know about gold mining is: 

• Miners use tools to dig a private underground that goes through another country or somewhere. Miners also use special tools to get through the walls. 
• I think Miner's objective is to find as many golds as they can and then deliver it to their company and sell them. Or they can trade it with something that is the same amount of cost as a gold. 
• If there are stream with water somewhere in an underground gold mining, they use a scooper and tries to get golds. And then they wash it off with clean water and use their eyes if there is any gold. 
• Gold miners maybe also can find a way to get to their company just by going back and forth. Or they can just build their own space to put all their tools and stuff in it. 

Now I am going to talk about discrimination and what the things I know about discrimination.

• My opinion about discrimination Is racism about people being racist to our or their society. 
• Discrimination is maybe also how racist people talk about other colour skins and which culture they came from. 

Question of the day: 

What does discrimination mean and why is it so important? 

Hope you enjoyed my blog post about my knowledge about gold mining and discrimination, make sure to leave a comment. 

Needs VS Want

In our healthy lifestyle session, we have been learning about the best decision/choice to make. So we have been comparing against need and want. The difference between the two of them is need is really important but want is the things that are not important but like. So we made a presentation to give the examples of need vs want also we had to write the definition of both of them. We had different websites to present our work so that is creative. 

It was really fun to do this task in our healthy lifestyle session because sometimes this work can give tips to our lives. I am very proud of myself because I completed my work and the definition of both of them. But the really hard part was when I think of ideas the differences of one another, especially the things you need.

Here is my completed work:

Question of the day: Why are need and want different?
