BTN Solar System

This article was about how the people that draw diagrams about space have it terribly disproportioned.

In this video they said that if they find out a few ratios and proportioned them down to a particular size. When they did this they sized the earth down to a marble. And the sun 1.22m across the did this because the this sun was the same size of the sun in the sky from our perspective, even though they made the earth the size of a marble the distance between the sun and Neptune was still 12,000m in radius. This shows that all those diagrams of the solar system are horrifically wrong and they also show false colours orbits in circles not ellipsis and heaps of other things. This just shows how big the solar system is and my question is, how would the solar system work if the usual diagrams were accurate?

100 Word Challenge-My Year

My year has been successful and bad

Stressful and sad

Although I fear

For high school is near

I have to leave here

For many could shed tears

We are leaving our friends

But hopefully this is not the end

But it’s time for us to ascend

And to attend

Our yearend

Graduation accommodation

It’s time for a transformation

The song is playing

And we are swaying

Our parents cheer

For the end of our primary school career

Without friends, our life will be dull and damp

It has been brightened by camp

But I’m ready for, primary school revamped

Goals for last term and High School

My Goals

I would like to learn about ratios and scales, how to find out the area of a curved shape and  how to convert between percentage, decimals and fractions. And also some strategies used in narrative writing, and also how to do division with decimals. A way I can achieve these goals is participating with the class, trying my best and always being enthusiastic. Another goal I could aim for is shortening down my notes so I can write faster, because I will need this in high school and university.


With these goals, I believe I am going well and already have achieved some goals. I have learnt more about ratios and scales because since I am starting to understand math more I understand ratios more. Sadly we haven’t found the area of curved shape because that’s pretty high math and I’m in year 6. And I have found out how to convert between all fraction types. And I am on the way with my narrative because of I am told my narrative is going well so far, but we have not done decimal division.

Future Goals

Next year I am in high school so my goals will be about high school, so I would like to be always open to new learning opportunities, and will be ready for the new advanced subjects. I will also be open minded about the new subjects that they offer, like woodwork, biology, business, etc. that primary school has not offered us. I also know high school is much harder on homework, so I will be more organised and plan my homework so I get it done, I will also have to make new friends in the yard.

Space Reflection #4

This article was about how a company named spacex is willing to try and send people to mars and start a colonisation there.

The company spacex wants to send 100 people on a spaceship to mars using one main rocket and 3 gas refuelling rockets, but while doing this they say it will take 80 days to get to mars which is an incredibly fast time and it will have a very low cost per rocket not even breaking the $200,000 mark, which is a very low price. They man running the lecture was talking about how to get there how to start a colony and getting everyone there in the first place , but he forgot to mention health, food, water and oxygen; Which you cannot find that much of on mars. When he was talking about the fuel he said he will be using methane gas, on Wikipedia they said this is a very popular fuel and I knew that our farts contain a bit of methane, so it is some sort of natural gas from plants and food, etc. He is also using this gas because for the return journey he says that the people on mars can harvest methane gas from mars itself and use that as a fuel, but from what will he harvest this from? As you can see spacex is a high end company and is dealing with some pretty high tech stuff, but I wonder if this is a government supported company and if they are legally allowed to send these people to space and most likely die if this becomes a reality?

Space Reflection #3

This article was about how 3 years ago a meteor nearly hit Russia.

In 2013 a meteor nearly hit Russia, It was big and got far into the earth’s atmosphere, but the force was apparently 20X bigger than an atomic bomb, which is an unbelievable force because it didn’t even hit the ground and it got that much power from just falling, imagine if it actually hit the ground generating more force and making a MASSIVE explosion. Although it did not hit the earth’s crust  due to that it burned up before it could make contact with the ground. But what is the difference between meteors, meteorites, comets, etc. A comet is a chunk of ice and dust from the farther parts of the solar system; this is probably because it was very cold, but if comets are made of ice, where did the water come from? But although for some reason we call the hunks of metal that actually come in contact with our planet meteorites, instead of meteors; the one that don’t come in contact with out planet.

Space Reflection #2

This article was about mixed facts about the solar system and its planets.

The solar system is a series of objects that orbit the sun due to the means of gravity. The way that they suppose earth will end is when the sun burns out of energy, swelling up. This can either engulf earth entirely or just nearly completely melt the crust. That it will shrink down into a white dwarf and all the planets will depart from the suns orbit drifting away. Although on the internet I heard that it will swell up into a red giant star and the explode causing a supernova, or collapse on itself creating a black hole. Another interesting fact is that the sun makes up approximately 99.87% of the solar systems mass. This is a gigantic amount. And the earth doesn’t even take up all that much. It’s more of a tiny speck, with Jupiter taking up most of the remaining mass. If earth was created before the sun was created, what happened to the earth before it came part of the solar system and it started to orbit the sun?

Space Reflection #1

This Article, that can be found on my teachers ‘blog; antsclass. Is about how 3 different ancient civilisations discovered different things about astronomy.
There were 3 different civilisations that found out a few things about astronomy, Babylon, Maya and the Greeks. Babylon had discovered how to make such things as calendars and such, but I would also believe they created the system of how time works. An astrologer by the name of tamely that was born in Egypt while under the rule of the romans, discovered a system called the `Ptolemaic system`, which suggested that the earth was in the centre of the solar system which many believed, but now it is deemed false. Although he got a lot of his knowledge from a man called hiparcus. A question that I have and am sure a lot of other people have is how did they figure all this out in the ancient times, even if it was incorrect?

Science Goals For Term 4

For our topic this term we are doing a science unit about space, because this is our topic, these are a few goals that i have set for myself.

Science As a Human Endeavour

As one of my goals about space, I want to know how gravitational waves affect our lives and how they work and what their effect is.

And I also want to know about how the moon affects tides of the ocean.

Earth and Space Sciences

About how the earth works, I would like that know what makes earth orbit the sun like it does and what gravitational pulls are.

Science Inquiry Skills

To help me with these goals I would like to be able to use graphs, tables, observations, etc. to discover patterns and create relationships of information gained from other lessons and experiments.

October 3

Goals I have Achieved and Where to Next

I have not learnt about ratios and scales and also how to find out the area of a curved shape due to the fact that I haven’t been taught them during class time. But what I did learn was how to convert from fractions, decimals and percentage when I was learning in class and also revision from last year. I didn’t learn about sound and the human body but on the up side we did learn about natural disasters another area of science and we learnt that through our integrated studies unit through making an information text. We didn’t have a topic on history so we didn’t learn about history nor did we work all that much on narratives for unknown reasons.

Due to the fact that our topic this term is about space, something I would like to improve on in the future is; a lot of random facts about space, because I don’t know all that much about space at the moment, I can’t really say what I would like to learn about, I would like to learn about anything really. I would also like to revise bidmas and do some pretty tricky equations. I also find shapes and angles would be very interesting so I would like to learn about that, and finally I would like to learn to make a map which I think my teacher said we were doing.

With a sudden shock the whole villages were wiped out, lives lost, people left homeless, no food left, no clean water, no help, no hope, this is the deadly reality of an earthquake. Now many may be left wondering how this all started, well, it all starts with the tectonic plates.


2-Tectonic Plates

One of the main fundamentals of earthquakes is the movement of tectonic plates. The movement of the plates are the building blocks of how earthquakes occur. Each year tectonic plates move approximately 2-5 centimetres and they move slowly over the globe. Due to the slow movement of tectonic plates earthquakes cannot occur all that often. Tectonic plates move because the radioactivity/heat from the earth’s core pushes against the tectonic plates causing it to move, and as the gas cools down it moves back down into the earth’s core (Convection). This is an incredibly slow process and can take years to make a major earthquake occur. The way that the tectonic plates move is determined on which way the gas rubs against the tectonic plates, this is also why some plates move towards each other and some plates move away from each other. When they move into each other this is called the subduction zone and this is where the tectonic plates collide. When they move apart this is called divergent plate boundaries.



When the crust goes under and over each other at the subduction zones (sometimes these collide causing an earthquake), the crust goes down into the mantle later melting into magma/lava becoming part of the mantle. Some of it goes into the magma chamber of a volcano, and as the pressure slowly builds up a volcanic eruption occurs. This can be seen looking at a map of volcanoes and tectonic plates, on the boundaries of the tectonic plates there are multiple volcanoes, this is also why the ring of fire exists. On a subduction zone this is where the plates go under and over each other, and where the rocks may be on a fault. It is also where the plates occasionally collide causing an earthquake, and is where most earthquakes occur. At subduction zones an oceanic plate slides under a continental plate or under another oceanic plate, (this is because oceanic plates are denser therefore floating lower on the mantle while the continental plates are less dense and they float higher on top of the mantle). This is where geo hazards (earthquakes & volcanoes) occur. The actual earthquakes are caused when rock that is underground breaks along a fault, and then the seismic energy and seismic waves make the ground shake. However, how this energy is released is when the 2 rocks and/or plates are rubbing against each other, the place that the rocks broke is rigid, so they won’t slide smoothly against each other. So the rocks on either side will catch on to each other, but the rocks are still pushing against each other but the rocks are stopping the motion. So soon there will be too much pressure built up and the rocks will break, releasing seismic waves, causing an earthquake. The severity of an earthquake is caused by how much pressure is built up when the rocks stopped the plates rubbing against each other.

The positioning of the plates change a lot of things as well, because as stated earlier, where the tectonic plate boundaries are is basically prone to earthquakes and/or volcanoes. Volcanoes are just the crust that had melted after it had gone into the mantle when the tectonic plates were moving under and over each other and the crust had to go somewhere. At because at the divergent plate boundaries the gap spreads, which would leave a giant gap, well, the magma from the mantle rises up, because the convection currents push this up, So in reality the earth is just recycling rock that was melted into the mantle, over and over again. On tectonic plates there are also things called collisional boundaries, this is where 2 plates of the continental lithosphere collide. As they collide the rock is pushed upwards therefore creating mountains, this is apparently how the Himalayas and the Alps were formed. This would also create devastating earthquakes.






Pangea was a phenomenon that occurred 300 million years ago when all the land masses we know as countries and continents were formed together. Until 175 million years ago the tectonic plates began to move, therefore moving the continents/continental plates away from each other, hence the name, Continental drift. Because of the ways tectonic plates work, NASA estimates that in 250 million years from now, Pangea will form again and what they call Pangea Ultima. This would probably cause devastating earthquakes that would be unimaginable. Although our countries won’t go underneath each other and engulf each other, because only oceanic crust goes under continental crust, continental crust doesn’t go under continental crust. Instead the continent will clash, causing earthquakes; these would be collisional boundaries and will cause a lot of mountains to form.


3-Seismic Waves
But there are also something called seismic waves. When an earthquake occurs there are 2 types of seismic waves; surface waves and body waves. Body waves are seismic waves that travel through solids & liquids, so they travel through the earth, the rock and the mantle. Body waves are faster than surface waves and are of higher frequency. But there are specific types of body waves; there are P waves and S waves. P waves, also known as the primary wave, these are the fastest type of seismic wave, and they are the first to arrive at the `seismic station`. P waves push and pull rock, although these are not that deadly because people normally only fell the rattle of the wave. P waves are also called compressional waves because of the way that they act, the particles move in the same direction that the wave moves, or the same direction the energy is moving, this is called the `direction of propagation`, here is a link to show a better understanding;                                                              But P waves are not the only type of body wave; there are also S waves, also known as; Secondary Waves. S waves are the second waves that arrive at a seismic station, therefore making it slower than the P wave and faster than both surface waves. But what makes it special is that the S wave cannot move through liquid, it can only move through a solid, S waves move the rock particles up and down and side to side, perpendicular to the direction the wave is travelling in, (The direction of wave propagation), here is yet another link to explain how S waves work;                                                        During the description of S waves It was confirmed that S waves can only go through solids and not liquids, so this is what led seismologists to believe that the earth’s outer core is actually a liquid.




But there are also things called surface Waves, these waves don’t go through the inner layers of the earth, instead the travel along the surface of the earth. Unlike Body waves, surface waves only travel through the crust and have a lower frequency than body waves. These arrive after the body waves, and are mainly responsible for the destruction caused by an earthquake. The first type of surface wave is the Love wave, this is the fastest type of surface wave and moves the particles entirely from side to side, and this wave was named after A.E.H Love who found the mathematical model for this wave in 1911. This is how the love wave works;                                                               then there is the Rayleigh wave. A Rayleigh wave rolls along the ground like a wave rolls along the ocean, this moves up and down, side to side in the direction that it is moving, Rayleigh waves are one of the biggest waves, and causes most of the shaking, here is a diagram to show how it works;


4-Graph on Magnitudes



Here is a graph of the mean average of the magnitudes of DEADLY earthquakes from 1990-2000, the question posing was; have the magnitude of earthquakes gone higher over the years? The graph looks like it’s in a completely random order, because it is. It is up to chance if the magnitude of earthquakes will be increasingly higher or lower each year, and it will always be that way. Because the tectonic plates always move about the same each year, and earthquakes have developed a system that will most probably never stop, so the magnitudes of earthquakes is just chance. Most likely earthquakes will just have random magnitudes.


5-Diagram of Earth’s Core

This diagram shows the layers of the earth and many other minor details regarding the topic that this information text is about. First of all there is the inner core; this is made of iron and a few other elements. Its heat ranges from 5000-7000 degrees Celsius, (the iron has not melted due to the sheer pressure of the weight on it). Then there is the outer core, this is a liquid layer of the earth’s core. And the heat is ranging from 4000-5000 degrees Celsius. While the mantle is made up of magma (semi-molten rock) and its heat is from 500-900 degrees Celsius. Finally there is the crust, this is where the tectonic plates lie and where all the magic, that is earthquakes happen. There is a dark grey line that is the lithosphere; the lithosphere is the uppermost part of the mantle and all of the crust. And the lithosphere is made up of tectonic plates, so the lithosphere IS the tectonic plates except it represents the tectonic plates as a whole. There are also those arrows, these are called `Convection currents`. Convection is how heat is transferred by mass motion of air and water (fluids) when a heated fluid is forced to move away from the source of heat carrying energy (the heat) with it. Convection above a hot surface occurs because when the air is heated it expands and becomes less dense, therefore it rises, and a convection current is simply when a current in a fluid that is caused by convection, much like how a current in water works. So convection currents come from the earth’s core, because of the heat making the fluid less dense, causing it to rise with the energy (heat) then when it reaches the mid-ocean ridges/tectonic plates the energy (heat) is lost. Causing the fluid to cool down, which makes the fluid denser therefore making it float back to the earth’s core. There are also mid-ocean ridges; this is where an underwater mountain range is created by tectonic plates. This is caused when the convection currents rise under the oceanic crust, and that created magma where 2 tectonic plates meet at a divergent plate boundary.














6-System Analysis

System Analysis:

If there wasn’t any radiation coming from the earth’s core, the tectonic plates wouldn’t move, so at the subduction zones nothing would happen and no seismic waves would’ve been released, therefore there would be no such thing as an  earthquake. Now if there is no such thing as subduction zones/fault lines, so that would probably mean that the continents will just move in a circlearound the sphere that is earth, endlessly, which wouldn’t change that much, and there will also be no such thiing as earthquakes. But if no rocks got stuck on each other, firstly the earth will have to be completely spherical and there would be no mountains, the earth will have to be COMPLETELY spherical so the rocks couldn’t catch onto eachother and would just run smoothly into the mantle, and once again there would be no such thing as earthquakes. BUT what if the rocks that caught onto eachother didn’t break, like an immovable object? Well, the whole entire movement of tectonic plates will probably halt, and the earth’s continents wouldn’t move, therefore leading to no earthquakes, but what if the movement of tectonic plates was an unstoppable force?, wouldn’t the earth’s tectonic plates be able to break it, right? If there were no seismic waves?, Well quite simply if no seismic waves were released the earth wouldn’t shake, so there would be no earthquakes, BUT what if there was no such thing as body waves. Well as stated before body waves only cause minor damage and surface waves cause the most damage so most of the damage will still happen, but if there was no such thing a surface waves most of the damage will still happen, and finally if the seismic waves didn’t move any particles at all, there would be no such thing as earthquakes, and seismic waves probably wouldn’t be noticable and we would never know of their existence.





Tectonic Plates-Tectonic plates make up what’s known as the lithosphere, (crust &upper mantle) there are 8 major tectonic plates, the convection from the earth’s core moves these plates 2-5 centimetres a year.

Subduction zone-A subduction zone is where the tectonic plates meet, when the tectonic plates move, they have to go somewhere, so they meet at subduction zones. The tectonic plates go underneath each other soon melting into the mantle.

Divergent plate boundaries-This is where the tectonic plates are moving away from each other, because at the subduction zones they move towards each other, when this happens the convection currents push the mantle up taking the place of the crust that had gone into the mantle at subduction zones.

Fault/Fault line-A fault is a break in the earth’s crust, what defines a fault is the movement of the rocks on either side, when this movement is sudden an earthquake occurs.

Collisional boundaries-Collisional boundaries also known as continent collision is when at convergent boundaries the subduction zone gets destroyed mountains are created and 2 countries are stuck together.

Convergent boundary-A convergent boundary is when 2 or more tectonic plates (or parts of the lithosphere) move towards each other and collide.

Mid-ocean ridges-A mid ocean ridge is a underwater mountain range, this is created when convection currents make the mantle rise where 2 tectonic plates meet at a divergent plate boundary

Lithosphere-The lithosphere is the rigid and hard outside consisting of the upper mantle and the crust, the lithosphere is made up of tectonic plates.

Crust –The crust is made up of igneous and many other types of rocks. And this is uppermost part of the earth.

Igneous rocks-Igneous rocks are just solidified magma and lava.

Mantle-The mantle is in between the crust and the outer core (as shown on diagram) and is a silicate rocky shell, this makes up 84% of the earth’s volume.

Outer core- the inner core is the fluid layer of the earth, and is mostly composed of iron and nickel.

Inner core- this is the innermost part of the earth and is primarily a solid iron ball.

Continental crust-The continental crust is the crust that we know as countries, it is older than oceanic crust and the reason that it is elevated higher than oceanic crust is because it is less dense, causing it to float higher on the mantle.

Oceanic crust-Oceanic crust is the crust that is denser so it’s elevated lower on the mantle, these also hold midocean ridges.

Dense-A closely compacted substance or a substance that particles are closely compacted.

Geo Hazards-Also known as geological hazards are hazards such as volcanoes and earthquakes.

Convection-Convection is heat transfer by mass motion, when a heated fluid is forced to move away from source of heat, carrying the energy/heat with it. When convection occurs above a hot surface, the air expands causing it to become less dense and rise, but when it loses the energy/heat it goes back to normal and sinks back down.

Convection current-a convection is a current that is formed by the process of convection.

Fluid-A fluid is practically a gas or most commonly a fluid.

Radioactivity-Also known and radioactive decay, this is when an unstable atom loses energy emitting radiation. Every material does this, except radioactive materials do it much quicker.

Pangea/Pangea ultima-Pangea was a super continent that consisted of all the countries and continents that we know today, it was assembled 300 million years ago and began to drift 175 million years ago. Although Pangea ultima is what NASA is suggesting will occur in 250 million years, this is when all the continents will from back together.

Seismic Waves-A wave in the earth that is caused by earthquakes, this is much like sound waves and how they work. These are also described as waves of energy that travel through and on top of the earth’s layers. Surface waves consist of Love waves and Rayleigh waves.

Surface waves-Surface waves are a type of seismic wave that travels along the top of the earth’s crust, these have longer wavelengths and they travel slower than body waves.

Body waves-A body wave is a type of seismic wave that travels through the earth’s layers, these have shorter wavelengths and are faster than surface waves. Body waves consist of P waves and S waves.

Seismic station-A seismic station is a laboratory that has the equipment to detect, monitor and record earthquakes locally and/or anywhere in the world.

Frequency-frequency is how much a repeated circuit happens in one second, this can be shown by wavelengths, this has a different meaning with sound and other science areas.

Direction of propagation-In geology, direction of propagation is the way the seismic waves move or the way the energy moves, the way the energy moves is also the way the particles move.

Particles- A particle is a minute fragment or quantity of matter.

Pressure-A continuous physical force exerted on an object and/or something in contact with it.

Seismologists-Seismologists are a certain type of scientist that studies earthquakes and other geological hazards; they also use tools and equipment to monitor the earth’s crust.

Magnitude-A magnitude is a number that characterizes an earthquake and how big it is. Magnitude is based on the maximum motion given to a seismograph and is measured on the Richter scale.




Earthquakes will always be around and will always devastate our daily lives, this is an ongoing thing and will never stop until the world either ends or we can make it stop.

This is my self assessment for my term 3 project of 2016


And finally this is an assessment reflection on which  I reflect on the work that i have done, while assessing myself.

This was definitely one of the hardest projects I’ve done, during this project I had a shorter time to complete it than any other person and I am very proud of what I have accomplished. I am proud of the facts and research I put into this and the effort that I put into every sentence. I really like the graph and the diagram I made because they let the people understand my work better. I am also VERY proud of the number of words (3100) that I have included in this, with no repeating to make the information report longer. I like the number of tier 3 words and I like how this can be used to each higher audiences than my own.

Although there are some things I need to improve. One thing that I think I need to improve  is my system analysis, I thought it was bland, it didn’t teach anyone anything, it’s either that I am not seeing what you can learn from it or I am not understanding and not looking for the information that will teach people things. One other thing is that my glossary might’ve been a bit too much copied. Because I found it hard finding definition in my own words of tier 3 words of that level.

But all in all, I believe I have done a great information report for the  amount of time that I’ve got to do this (A bit more than a week) and I am so proud of myself.
