Science Reflection

This was the video I reflected on:

http://antsclass.global2.vic.edu.au/2016/12/05/space-homework-3/

I would definitely recommend this video to watch. I found it very interesting to watch, and the information I learnt truly amazed me. So please watch this video if you have time!

This video was about solar system and the size/scale of it. Here’s a quote explaining what it’s like to see Earth in space.

“As we got farther and farther away, the Earth diminished in size. Finally it shrank to the size of a marble, the most beautiful marble you can imagine… seeing this can change a man.” James Irwin Apollo 15. Who did it changed? Did they do anything about it?

 

See, the actual size of planets are microscopic, on a piece of paper you can’t see them. But it’s the opposite with the distance from the sun to the moon, it’s actually way bigger than what we think it is.

So if we can’t see how big the solar system is, how can we know? Well, the only way to see the actual size of the solar system is to build it.

In the black rye desert, Alex Gorosh and Wylie Overstreet set up camp and in 36 hours they measure distances, trace out orbits and set up a time lap video (which had to be shot from up on top of a nearby mountain). When the time lap had finished, they would light up a marble on a stand where a planet is support to be. When it was lighten, you could see how big the solar system actually is (from the lines/orbit). Here is what the planets ended up being on the scale:

(Smallest to biggest)

Mercury was 68 m/224 feet.

Venus 120 m/447 feet

Earth 176 m/579 feet

Mars (actually has robots on this planet) 269 m/881 feet                                 

Jupiter 0.92 km/0.51 mi

Saturn 1.7 km/1.1 mi

Uranus- 3.4 km/2.1  mi

Neptune (the edge of the solar system)- 5.6 km /3.5 mi

By the planet Jupiter, the orbits were becoming giant! Neptune’s was the biggest out of all of the planets, and it was ginormous. You can see how big all of the orbits were (they were HUGE) in the video (at the top of the page-link, from 2.20 min to 4.33 min).

 

To prove that they had done this correctly, they decided to test this scale with the sun. They tested by seeing whether the sun they created (the size at sunrise) is the same size as the actual one at sunrise. It was, so they were correct. The sun was a meter and a half on the scale

 

There are 24 people out of billions who have seen the full circle of earth. Why only 24?

 

Earth’s orbit doesn’t rise, it curves. When you head on out to the moon, the horizon slowly curves around and then you’re looking at something that’s very strange yet very familiar. Earth. If you’re in space and you’re looking out at Earth, you can put your thumb up and can hide Earth.

 

I now understand actually how huge solar system is, and how big the planets actually are.

Space Reflection- Ancient Greeks

Video on: http://antsclass.global2.vic.edu.au/2016/11/27/space-homework-2/

Blue = Facts

This video was about how ancient Greeks thought about our solar system, galaxy and the cosmos, and how their ideas grew.

 The ancient Greeks used to believe that the sun and the stars moved around earth for this reason, because earth was in the centre of the solar system. Also, they believed that it had to be the stars and the sun moving (not earth), for if earth was moving we would feel it. How did the ancient Greeks even know about space? At the time, these assumptions was actually a simple mistake to be made. So since they thought this, they drew the solar system with earth in the centre, the moon opposite it and then the sun opposite the moon. Which leaves the stars, which would be rotating around earth in a circle. I understand how beliefs passed down for centuries can really affect what you believe, and how it’s not always the correct assumption.

But one day they found that something didn’t move in a circle but back and forth, so the Greeks had to change the model. Or course they hadn’t worked out what that thing was, but they decided to give it a shot. Astronomers developed more complex models, with happened to have more circles in them. Finally, one day a better model than any was created. This model the astronomers put the sun in the middle of our solar system (which is where it actually belongs).

This model led them to finding out what was the thing that went back and forth across the night sky. This thing was a planet, and it was called Mars.

So after all of this discovery and new information, they should have a pretty good representation… Actually no. At this point in time, they went even close. It wasn’t until Galileo Galilei built the first telescope that they actually got somewhere. When was the first telescope built? It showed things like how Jupiter has four moons.

But this telescope also showed everyone what the real representation of our solar system is.

So now, the current model shows all the planets orbiting around the sun. It also shows that if the sun and stars move across the sky, then the earth must be rotating to make them move.

 

Questions Answers:

  1. The first telescope made was built in 1608 by a German-Dutch lens maker, who went by the name Hans Lippershey.

Website: https://www.spaceanswers.com

 

  1. The knowledge of space was given to them by other cultures. Chinese Astronomers, Mesopotamian and Zoroastrian astronomers/astrologers and even Indian Vedas mainly helped out the Greeks with their knowledge. Most of the knowledge though was given when Alexander the Great conquered the region, in 331 BCE.

School holidays are coming up, and thank god it’s going to be hot. Swimming pools, hanging out with friends, water fights. How much better can school holidays get? But many years ago, something really important happened in the school holidays. The first person was sent into space! So go celebrate this, this article will be about the biggest events in our history about space.

When we look up at the sky with millions of stars, what we are really seeing is a whole universe of planets, asteroids, moons and suns. But these things were so far away from mankind, that we couldn’t really explore them. But on April 12, 1961 we started. Yuri Gagarin was a Russian cosmonaut flying in the Vostok 1, and he became the first person to make it into space. And this remarkable trip, helped change everything.

Space is a very hostile place. No air too breathe, the temperature is freezing cold, and doesn’t sound like the most enjoyable place. But for countries like the U.S and Russia, well they wanted to know everything about space.  An insight I have is I understand how they want to find out more. They get introduced to something no one knows that much about, you would want to learn more about it.

In fact, the president of the United States stated:

“We choose to go to the moon in this decade and do the other things not because they are easy but because they are hard.”

So saying this, massive amounts of research and money went into creating a rocket called Apollo 11.  And when it landed on the moon on 20th July 1969, it became the first rocket to be on the moon.  Therefore, the two astronomers on this rocket ship became the first men to land/walk/float on the moon.  These 2 astronomers were Neil Armstrong and Buzz Aldrin, who happened to be from America. Neil Armstrong stated:

‘One small step for man, one giant leap for mankind’.

And he was completely true.

But then even bigger things happened.

In the 1970’s, the U.S.A set up Skylab, the first space station that let people live in space! In 1981, the launch of the space rocket Columbia started the beginning of reusable space craft. And they built the giant structure so big, that is was seen from Earth!

And guess what, there’s an international space station that people have been living there from the year 2000. The people there can answer questions you might have about space. A question I have is how did they collect all of this information? The knowledge gained from space missions and space stations can help other missions, like how satellites are orbiting the earth in their hundreds. And these satellites are still giving TV signals, phones and the internet all around the world.

 

But there are also downfalls to these incredible events, like how much it costs for human spaceflight, and to build and launch spaceships. It can cost billions, so most big projects now use unmanned satellites and advanced robots.

 

Now you might think that we know EVERYTHING about space, but the truth is we have a lot to learn about our universe.  Recently sending people has been helping us find out more about space, and its gone to the point where some companies have set up space tourism programs to take people beyond Earth’s atmosphere, just for the experience! Here’s an example of this, and it’s a true add:

“Virgin Galactic is on track to become the world’s first commercial space line and if you’ve ever dreamt of joining the incredible group of pioneering astronauts your opportunity has arrived.”

 

But this isn’t the only add out there who wants people to join them to go to space, there’s way more. In fact, there’s a project right now that wants to send people to mars to create a reality tv show. This cast will be going to stay and live on mars, and it’s a one way ticket only. A question I have is what type of people are they looking for to be in this project?

 

So if all of this happens, we would have proven that we have the technology to send people to our space. But we could also prove we have the technology to travel further. So, while were getting ready to celebrate sending huge amounts of people into space, the future of exploring space is still very interesting and exciting.

This article is about the SpaceX project and how they want to send humans to mars. The first thing you need to know is, well you might be living on mars in the next 40- 100 years. In fact, Elon Musk (the owner of SpaceX) wants to have the first rocket to mars by 2024! That means that they want the first rocket to go in 8 years! As amazing/terrifying as it sounds, Elon has stated that the crew on this rocket will have to expect a high chance of dying. Though this may not affect as many people as you think, since a lot of people have come and listen to his speech on colonizing mars.

 

He has explained about the ships he’s planning to use, and he’ll need to build them as well. First step, a spaceship with 450 tons of cargo. It needs to carry up to more than 100 people at once. Next step, launch it into earth’s orbit. For this to happen, he plans on having a massive booster that will be powering the ship on its journey. But it sure will need to be powerful, for the spaceship (by the sound of it) is going to be massive! It is so big that it’s larger than NASA’s Saturn V rocket! To power something this huge, you need 42 raptors. And how to power these raptors, well how about some methane? I think this is an amazing idea because methane is really bad for the environment and isn’t really helping us. And if we can use it to help us get somewhere important and not destroy our oxygen, that would be terrific! So these boosters will then shoot this spacecraft out into Earth’s orbit, but the next step might confuse you. They want the spaceship come back down and land on the launch pad. This is because of the crucial next step, they refill the petrol (with the second fuel capsule they have) and send it back up again! The last step is very simple, with the leftover petrol they had (the first time around) and the new petrol, they will fly to mars.

 

The rocket would be powered by 42 raptor engines, space X did their first test of the engine and this engine actually runs on methane. When the rocket goes into space the 2nd part of it will detach and float down to earth in the original position then when it’s in the position another top part of the space ship is connected to the bottom and then sent into space again and so on. I now understand that astronomers are working really hard to try and get our future of space exploration to be understandable and to one day send astronauts and other people into space and to mars.

 

Elon Musk is in charge of this project, he’s the CEO of this company. And as he has stated, his main goal (all he really wants in this) is to colonize Mars. Of course they will be some minor problems, like how all the resources we need (which Mars has them) are deep underground and might need some mining to get them. A question I have is how they are going to get these materials they need in time? And will the food, water, everything/anything be difference? What will be and how? Also, SpaceX wants to transform Mars to look like Earth, exactly. So they are planning to give this planet a makeover by launching thermos nuclear weapons at it.

 

A few extra questions I had were:

  1. What type of laws will be made on mars and what will they be based on?
  2. What kind of government will be formed on mars? Will it be the same as now, the same/different people, or a completely different system? What system, why and how?
  3. What will kids or even adults do in their free time to keep them busy (more based at kids)?

This video was about how astronomers eat food in space. Surprisingly enough, there is a lot of different options that you can eat in space, though the meals are a bit different to what we have on Earth.

First of all, they try to make the food very small so it’s less expensive (since space food is very expensive). Secondly, there is a lot of canned/packaged food, and they’re very simple to make (they come in canned/packaged/boxes so its stops them from floating around). They get boxes full of food, labelled which foods are which. The food is shared with everyone (of course) and any of the bonus food they get have to be approved (so there isn’t any microbial contamination that might cause health problems). Thirdly sometimes they have to eat their food with a straw, as well as they have to drink with a straw. Lastly, they even get some food already prepared for them, but the water they drink is just like ours on Earth (except they drink it out of a slip rather than a drink bottle and there’s flavours). But something very important about these meals are they have to be/are high in protein.

 

This is because when an astronomer is in space, they can be affected (since they’re in a weightless environment) in their bones and organs. But the most important part of your body (that they think) that can be affected is the muscles in your bones. That’s why astronomers’ food is filled with protein, so their body doesn’t get too affected.

 

Another priority about space food that you need to have is rations. As you already know, the food comes in packages/boxes and there labelled which one is which .But the labels also show what is rational and what can be consumed at how much. The red sticker stands for rational and the blue sticker shows that it can consumed however you like.

 

The last thing about space food is that astronomers do not waste any food in space (since it’s so expensive). But when the astronomers are finished with the food, they put the wrapper into a bag and repeat with other finished food until it’s full. Then they throw it out into space so it burns into the earth’s atmosphere.

 

An understanding I know have is how important and specific the food in space is, and how everything has to be approved.

2 questions I have are:

  1.  Did astronomers have a say/thought of the type of food they have in space?
  2.  How much food is sent up to space (and is it all used) as well as how much nutrition is in it?

On the 26/2/2013, a massive meteor explosion took place right over Russia. The same day an asteroid passed really close to earth, though these 2 events weren’t linked. This article is about the difference between asteroids, meteors and comet.

We live on the planet earth, and the way we live is pretty decent. There’s water, oxygen, the weather isn’t too cold or too hot, we can breathe fresh air and create buildings, and we can even have picnics! But were not the only planet or rock out there in our solar system, and that’s where asteroids, comets and meteors come in.

This meteor that hit Russia was in the Ural Mountains and it no one expected it. It strike through the atmosphere and exploded above a city called Chelyabinsk. The force it made was 20 times bigger than an atomic bomb, but since it was so high in the sky the effects on ground weren’t devastating. But the shockwave blew out the windows, damaged buildings and injured more than a thousand people. As this event occurred, astronomers watched an asteroid half the size of a football field passed closely by earth.

These 2 events weren’t connected at all, but they did get people talking about what’s really going on in space. See, there are more things in our solar system than the planets that orbit the sun.  There are chunks of dust, rock and ice in our solar system (which are the leftovers from the process that formed the planets billions of years ago). These are called asteroids, meteoroids and comets.

Comets are chunks of ice and dust which are from the cold outer parts of the solar system. When they get close to the sun they start to melt, therefore giving off a gas that looks like a beautiful glowing trail.

Asteroids are normally made of rock or metal. Tens of thousands of them are located in an area in the solar system called the asteroid belt (which is between Mars and Jupiter) but some travel closer to Earth.

Meteoroids are a smaller version of asteroids, and millions of them hit the Earth’s atmosphere every day. When they enter the atmosphere, we change the name to meteors. Most meteors burn up really quickly when they hit the atmosphere, and if you’ve ever seen a shooting star, that’s a meteor.

This meteor that flew over Paris was bigger than most meteors, and because it was made of the things it was made of, it didn’t explode straight away. It exploded when it hit thicker air, and this has happened in Russia before. In 1908, scientists believe that a massive meteor exploded above a place called Tunguska. Nothing from the meteor reached the ground, but the force of it knocked down kilometers of trees. But when a meteor does hit the round, we call it a meteorite.

When we do get meteorites, they can be very valuable. This is because they give more knowledge to scientist to find out what’s going on in space, and to be able to touch a rock from space that is billions of years old, it would be amazing!

Damaging meteor/meteorites events on earth are rare, but they can happen. A lot of scientist believe that one reason why the dinosaurs became extinct (over 66 million years ago) was because of a meteorite. But scientist also believe that this type of event will probably not happen in our lifetime again, so humans are in no danger of meteors/meteorites. This is for astronomers spend a lot of time studying comets and asteroids, and finding things out like where they’re heading. Some can even send robotic spacecraft to study them up close, and they have different ways to protect the planet if one got to close. But these amazing comets, meteors and asteroids have a lot to teach us, and will teach us more about the ancient history of our solar system than ever in history.

 

An understanding I now have is:

Meteors, asteroids and comets are clearly linked but are they own different things, though we also could expand our knowledge on them (especially comets and asteroids).

 

2 questions I have are:

  1. What different ways can the robotic spacecraft (sent by astronomers) protect our planet?
  2. What equipment do astronomers, or even scientists, have to find out this information (besides the spacecraft)?

This article is about our solar system and what we know about it (generally). The solar system is a series of objects that orbit the sun because of gravity. It consists of In consists of galaxies, planets, asteroids and many more. Our solar system is a tiny percent of what we call Space, which is enormous! Our solar system is located in a calmer part of the Milky Way, which all humans in our solar system live.

 

There are 8 planets in our solar system, which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Each planet is either a gas planet or a terrestrial planet, but this doesn’t include the bunch of dwarf planets (I will expand on dwarf planets a bit later). Mercury, Venus, Earth and mars are terrestrial planets, but they are tiny compared to the gas planets Jupiter, Saturn, Uranus and Neptune (in fact these gas planets contain 99% of the mass of all the other planets combined!). Although these planets can be named into groups, they are very different. They can have different temperatures, weights, moons, weather, sizes, distance from the sun, and even simple things like the colour of the planet.  But there are still similarity’s about the planets like:

  1. Every planets has to be a sphere
  2. Every planet has cleared orbit
  3. All of the planets orbit the sun (Star Sol).

 

And all together, the planets make up 0.14% of our solar system.

 

 

Dwarf planets are also very different to each other and have categories, except theirs are based on where they are in the solar system. The two categories are the Asteroid Belt (the dwarf planets are between Mars and Jupiter), and the Kuiper Belt (the boundary of the solar system). In these belts are also the trillions of asteroids and comets in our solar system. The all circle the sun, and some examples of dwarf planets are Pluto, Ceres, Makemake and Haumea.  Ceres is the most known object in the Asteroid Belt, while Pluto, Makemake and Haumea are the best known objects in the Kuiper Belt. Although there are millions of objects in these belts, both are pretty empty. But the mass of these belts make up for it, the asteroid belt being 4% of the moons mass while the Kuiper belt is between 1/25 and 1/10 of Earth!

 

Another object in our solar system that is very important is our sun! It takes up 99.86% of our solar system mass, and it is made from mainly hydrogen, helium and less than 2% of oxygen and iron. The core of the sun consumes 620 million tons of hydrogen every second. Over the years the sun will get hotter and hotter, until when it get to the 500 million year make, the only thing that will remain in our solar system will be the 4 closest planets. Then the sun will melt each of the planets crusts, and the sun will get hotter. Then it will get so hot that it expands and swallows up these planets, or will turn them into a sea of lava. After the sun has done this, it will shrink into a white dwarf star and burn for a few billion years. Then the sun will die, and there will be no life in our solar system. The mankind in our solar system will be extinct, unless we leave and find somewhere else.

 

The solar system is so big that we haven’t even explored all of it yet. It has been around for 4 ½ billion years, and every year we learn something new about it. But we still haven’t developed the technology to find out everything about the solar system though we have found out a lot over the years.

 

I understand that we have found out so much about the solar system, yet we only have found out a tiny bit.

 

My Question is:

 When/will there be a time where we find out everything (or most things) about the solar system and will humankind still be there for it (the sun wouldn’t have swallowed us up)?

My 2 Question is:

When will we have the technology to discover everything (most things) about the solar system, and what will this technology do?

Landslides- How they can destroy us

 

Intro:

Heavy rain is pounding down as the crashing sound of a disaster fills the air. Death has its scent all over this, as person after person get trapped, and killed under the mass of rocks and dirt. A landslide is one of the natural disasters that can affect a person’s whole life, and can change it in a minute. A landslide is the movement when a mass of rock, debris or earth on a slope can no longer holds and gives way to gravity.  There are different types of landslides depending on the slope angle, climate, weathering, stabilisation, water content and a few more (a landslide can either fall, topple, flow, slide, spread). Landslides occur because of its terrifying triggers (earthquakes, volcanic eruptions, explosion, less deadly = soils that are filled with water, weak rock, the land arrangement, erosion, former of old landslide, vibrations of machines, vibration of traffic, deforestation, cultivation and construction). If a landslide happens underwater (submarine landslides) it can create a flood or a killer tsunami (since an earthquake triggers a landslide, the landslide would push the tsunami along faster and stronger). Lastly, landslides are prone around mountains and coastal areas. In the U.S, landslides occur in all 50 states. There are also other countries that experience this disaster, for example Alaska and Hawaii. Also, in Australia our prone areas are:

intro

Cited by http://www.ga.gov.au/

Coastal cliffs, the Great Dividing Range (along the east coast- submarine landslides), the Strzelecki and Otway Ranges (it is in southern Victoria), Mt Lofty Ranges (close to Adelaide, South Australia- volcanic eruptions), Mt Wellington (volcano eruptions), Tamar Valley, north-west coast of Tasmania, New South Wales and Victorian Alpine regions, and lastly south east of Queensland.

What humans do after a landslide?

25 to 50 humans annually die from a landslide, however the main complications that affect humans happen after the landslide.

The first thing a person will do after a landslide has occurred, is find the nearest safe shelter. Meanwhile, the population of the prone country, would listen to the radio or television announcement for updates on emergency information. Due to this fact, people will watch for signs of flooding. This is because flooding happens regularly after a landslide has taken place (if it was a submarine landslide, watch out for a tsunami). Then will also be the time to check for injured or trapped people. When directing the rescuers there to help, all humans must stay away from the area of the landslide. While all of this is taking place, the public (if they see any damaged railways, roads or utilities) will report this to authorities straight away. Then a group of people will check the land around them and assess where is safe. Lastly, the communities will replant the damaged ground so it won’t trigger any flash floods or additional landslides.

Humans after a landslide will receive goods from countries that are allies. They would receive canned food (it is canned because then it will not expire quickly), plastic water bottles (easy to transport), shelter (tents), clothes from charities and most importantly money (e.g. $1 000 000 American Red Cross gave to the 7.8 magnitude Nepal earthquake).

People in this situation do get a lot of donations, for example the Nepal Earthquake. 9 countries all sent at least 1 team of rescuers, food, medical aid, water, shelter and lastly all 9 countries (India, China, U.S.A, Canada, Israel, France, Australia, Norway and Switzerland) sent money.

Humans who have experienced a landslide, this is what happens when the volunteer groups come to help them:

Lifesaving aid will be the first action done when they get there. After a few hours of the disaster, volunteers will then be checking the level of severity and need.  Within 24-72 hours, the team/s there will provide emergency reliefs and they will be making assessments. At 72 hours, supplies will be loaded, transported and handed out. By the first week, emergency aid and relief to residents affected will be provided. After a month, citizens are stabilised (temporary shelter, water, sanitation and hygiene, child protection activities, healthcare etc.).

There are a lot of organisations and volunteer websites that help these people, and this activity a lot of people happen to experience after being in a landslide (or any natural disaster). Humans volunteer to go with groups of people to help out a country in need. Charities also cooperate in helping out, for they ask and receive donations.

Once all of this has taken place, the last action humans do after a landslide has occurred is to wait. They wait to found out whether it is safe to live where their home was anymore. Humans have an expectation to listen and follow instructions given to help them, as they have the right to be affected physically or mentally after.

 

How humans are affected:

Humankind can be affected in 2 different ways, physically and/or mentally. Physically, landslides can block roads, damage/destroy homes, locally disrupts sewers and power lines (very dangerous). They can even damage oil (big problem since it is really hard to find and collect oil) and gas production facilities. Also, transportation is delayed as well, and this can cause a lot of problems. For example, in 1919, a rockslide near Loggers Creek (close to Sea to the Sky Highway) delayed 12 days for travel and cost $1 million for prevention structure. A landslide is like dominoes, once it is triggered, it will keep on falling in a domino effect. It is also like an earthquake, though it is less common around the world.

Landslides also impact humans by making them pay more money to repair structures, loss of property, disruption of transportation routes, loss of medical aid and loss of materials. Water was one of the main materials that was damaged and the availability, quantity and quality was affected. And even after the landslide has happened, things are still costly like engineering projects that are designed to make the land safer. Lastly, if some people wanted to stabilise their houses after a landslide has hit, it would cost them usually hundreds of thousands of dollars for 2-3 houses.

The land around mankind can get affected very easily, but so can the environment. When a landslide occurs, there is a lot of economic loss. This affects humans for then they lose oxygen, which they need to breathe. And people need to breath to survive, so that is why a lot of plants get planted after a natural disaster has occurred (especially a landslide).

Land and the environment can get damaged very easily, but so can people. Landslides can hurt us physically, and also mentally. There are people outside of the country who are affected so they donate or volunteer. Also, countries can get affected and the government will help out by paying with taxes. So, the government and everyday people can get affected as well. As for people who are in the country hit, they can end up having trauma. If someone is in a natural disaster, they can see a lot of upsetting and traumatising events (seeing someone getting trapped or killed, seeing the effect of the landslide in the moment, thinking that there is no hope etc.). Some people even see a specialist after to get over their trauma. A landslide, or any natural disaster can leave people scarred.

Some people after a landslide are actually affected by scars. It is almost certain that if a person have experience being in a landslide (and has survived) they will come end up with an injury/s. People also die when experiencing a landslide, and the end result can be devastating. This happens because most killing landslides happen on highways, when people are trapped in their car. These types of landslide normally end up being a landslide where debris flows. They are extremely dangerous to animals, humans and the world. These killer landslides are so destructive, that most of them end up leaving long term damages. The only difference it has to other landslides is the debris. It might be a bit hard to picture, so here is a diagram showing you what the debris landslide looks like (the colour equals the rubbish).

diagram

 

This is why people need to prevent landslides.

 

What do humans do to prevent landslides?

The first thing that humans have done to try and slow down the effect of landslides is the Bureau of Transportation. The first action is to create stormwater management services so they can maintain the water, mud and debris that is pushed out by landslides and onto the streets. The second action is the safe transportation system for people after a landslide. Experts are focusing on detection systems so they can give warnings to residents about potential landslides. This can save lives and prevent loss of items, which will help the country a lot. Countries like the U.S.A have decided to look at the after affects. The United States Geological Survey (USGS) and the National Oceanic and Atmosphere Administrations (NOAA) have established a flash flood warning system to 8 prone countries within southern California. This system utilizes National Weather Services (NWS) and their Flash Flood Monitoring Production (FFMP) system. It recognises when flash floods and debris flows are likely to occur.

Another project is happening in the future, and it’s the Inventory Pilot Project. It designed to provide framework and tools to analyse landslide data into a listed digital format from individual states. Also, it will be able to scan reports and surveys so scientist can investigate.  A website will also be created, and it will be about clearly mapped out maps and data collections (their making this so they can promote more maps and data collections on landslides). This project and the website is going to be a long term goal.

 

USUG Landslide Hazards Program is a team of researchers to find out landslide prone areas, how frequent they are and create landslide hazard maps. To do this, they have to monitor to area. They monitor these things: rainfall, channel stage (sensing device that measures the flow height), ground water pressure, soil temperature, soil water content, ground vibrations, and battery voltage and station temperatures. Once scientists gather this information, they try to predict when the next landslide will be. They’re also trying to learn more about the triggers, that’s why monitoring can go from 15 to 24 hours straight. Here is a picture of what one of the monitoring sites look like:

Here is a website that has some professional maps about the different data they collected at monitoring in millicoma meaner: http://landslides.usgs.gov/monitoring/millicoma_meander/rtdmonitoring.php#channel\

There are everyday things humans can do to prevent landslides. They can check their draining system and direct the water away from them and their neighbours’ property, they can clean their gutters and check 1 a week during autumn and winter (these seasons because 1 wind or rain storm can clog a well-functioning drain), don’t litter and plug the cities drain (e.g. leaves cause flooding so do not plug drains with leaves) and plant trees and plants to reduce erosion on steep hills (so then it will be stable).

One more thing a person can do to help is to never discharge water over the side of an unstable, steep hill (this is because the water will put pressure on the soil, then the rocks will slide, causing a result of a landslide). If they do this, there will be a big, good difference to the frequency of landslides.  And if a person alter the slope, that will can reduce the risk and damage of the landslide. To do this, the person would reduce the upper part (the source area) and put it near the base. They would need to do this with professional help or else they could trigger a landslide by digging.

Another way to raise awareness is to make a video, and one website did. It is called Riding the Storm- Landslide Danger in the San Francisco Bay area- 1982 rainstorm. Here is a link to the video: http://pubs.usgs.gov/gip/2007/48/gip48_trailer.mp4

Comparing System to another (systems analysis below):

Landslides and earthquakes are quite similar, since landslides and earthquakes both cause destruction and damage (like any natural disaster). They affect people’s’ lives forever, and they both destroy parts of land (and with a tsunami after). There are different things about each other as well, for example earthquakes are measured in magnitude and landslides can create flash floods. These 2 systems are very alike, but they have minor differences.

 

Systems Analysis:

systems-analysis-finished-project

Change 1 step:

 

If there is a lot of plant roots in the slope, then you will need a lot of the other factors to create a landslide. Since the plants roots hold together the slope, if there was a lot of them it would be very hard to make the slope unstable. There would have to be other factors to effectively make a difference, and even then there wouldn’t be as big as an effect there would be without plants. But there are also plants that don’t help or their roots don’t make a difference. This would help a landslide, and these plants would help the landslide in the end. But if the other plants were planted, it would prevent the landslide for a bit longer.

Conclusion (system analysis):

People can affect landslides since they are a trigger (vibrations from traffic, vibrations from building sites etc.) Humans can start a landslide in everyday life, all that happens is the slope becomes more unstable, therefore starting the process. Humans can also affect it by planting plants that don’t help and pouring down water on the slope to gain weight. These are negative results, but something communities can do is plant plants that help. These plants have roots that stick the slope together, therefore making the slope more stable.

Conclusion:

Landslides are not known for being the most destructive natural disaster, though people do underestimate how much a landslide can/does affect us. Landslides are a natural disaster, and they can wreck someone’s life forever.  People can get affected by trauma, loss of property, death, loss of valuable items and physically injured when facing a landslide. Humans are affected every year, and they get hurt every time. A landslide is a dangerous and destructive natural disaster, and they can affect people more than they think.

And here’s my assessment sheet:

information-report-assessment-matrix finished

 

Here’s my assessment reflection:

Something I’m proud of after the assignment is how much detail I put into it. I tried really hard to get a lot of things on the assessment criteria, and tried to make it one of the best ones I have ever done. And I believe that I did a really good job and pushed myself to get this result.  I am also really proud of the way I handled my organisation in this project. I got the project done in time and I accomplished it well, even though there were things going on in my life.

 

Something I could have improved on is working on my tense. I haven’t been the best at using the right tense in my work, and I believe it needs to be a goal of mine. Also I could have used more comparative adjectives in my piece, and that will also be a goal for me. Lastly, I could have worked on using more simple sentences and to re-reading my work (maybe more than 3 times) for misspelt words.

BTN Working in Defence

Here’s the link to the BTN video: http://www.abc.net.au/btn/story/s4530720.htm

Blue: Facts

Red: Understandings

Green: Questions

 

This week, the defence force of the army have let a bunch of students experience the life of an army, navy or air force officer. This work experience program goes for 4 days and it gives interested students a bit of a run down on life in the Army, Air Force and Navy.  The army is doing this so they can try to get more adults to choose a career in defence. Now, this article is about what this particular group of adults did, and whether they enjoying it or not;

 

Day 1:

This brave group of adults started off looking at life in the army (military).They first had to learn camouflage techniques, then they had to camouflage themselves. If that’s not enough for some beginners, they had to camouflage a whole jeep! Then they went to a computer simulation, and had to do some target practice with pretend guns.

 

 

Day 2:

Day 2 was the Air force, and that meant flying in a C-17 Globemaster aircraft. This was a new learning experience for everyone, so all of the students got to take pictures, check out the cockpit and just explore the plane. This plane is an Air force plane, so it’s a lot bigger, noisier and has a lot more thrust than a normal plane. But all of the students said that they loved it (especially the view), and all of them got to see 2 pilots in action. The pilots were just about to land, and they saw them planning how they’re going to land (they were also talking about the weather conditions and how it could affect them).

 

Day 3 and 4:

Day 3 and 4 were about the Navy, and they went on the HMAS Adelaide. The lucky students got to board the huge ship, and they were super lucky to be able to stay the night. Most students enjoyed this part of the program, stating it gave them all more insight on what the navy is truly like. Also they met really cool people and apparently the food was good, so a big thumbs up!

 

 

Overall, all of these students said this was a great experience. We would defiantly hope so, since they all had to enrol for this amazing program. This is because it was created to show young Australians that are interested in joining the military what it’s really about. Students remarked that it was all really fun to learn about the areas, and they all had good impressions. They all learnt a lot of knowledge, and hopefully these kids reaction will give us a few more people in the defence team. After all, the defence force hopes this program will get people more engaged in working at this area, they also hoping to reach their target of 62,000 employees by 2025. So good luck to the defence team and great job to all of the students!

 

 

A understanding I know have is how important we need employees in the army. A lot of people don’t go for those type of roles, but they’re very important.

 

2 Questions I have are:

  1. Are there any other areas that need more employees. Which ones?
  2. Why are these specific jobs not getting a lot of people interested in them?

 

BTN- Australian’s new $5 bill

BTN video: http://www.abc.net.au/btn/story/s4526332.htm

 

This BTN video was about money and how our $5 bill is getting a makeover. Most people use money every day, but some think we should change the look of these rectangular pieces of plastic we exchange. See, the Reserve Bank of Australia believes that it’s time we change the designs of our money, starting with the $5 note.

 

Over the years, the rest of the notes will be presented with their new designs. In Australia, our notes are very recognisable for their designs. Starting with the bright colours, and ending with the famous Australians ($10 note is poet Banjo Patterson- Waltzing Matilda, and $20 note is Reverend John Flynn- created the Royal Flying Doctor Service). But from the 1st of September, our five dollar note will start to be replaced with the new one.

 

There’s a lot of changes in the new $5 bill, but there are still some similarities. The notes colour, size and famous face (Queen Elizabeth II) is going to be the same. But while saying that, a lot of new upgrades are coming as well. The first new upgrade is the window is now placed in the middle of the note, and has 2 new pictures on it (the Eastern Spinebill and the Prickly Moses Wattle).

 

Also, another upgrade was to up the security. This is because a lot of people want to print their own money, it’s kind of why our notes are made of plastic (1988 they decided to make our notes plastic so it’ll be harder to print real money). And in the old note, that little window has a seven pointed star you can only see when you hold it up to the light (so shopkeepers can tell the difference between a fake and a real note). Also in that little window was some micro printing (their really small words that you need a magnifying glass to read) so people could see whether the script was there or not. But our new note has a better system…

 

30 years later the $5 bill has seen a security check, and has been improved. Now it has things like in the bigger window, the five changes direction when you tilt it. Also, the eastern spinebill’s wings move when you tilt it to.

 

Now, to the last final feature that’s been added. For the first time in history of our bill system, the new notes will all have a tactile feature! A tactile helps people who are blind or can’t see really well (vision impaired) know what it is. In this case, this feature will help these people tell the difference between each note! This specific feature had a campaign for it, a boy called Connor created it. Last year he set up an online petition to have this feature on this note, and the RBA agreed!

 

So, it may be a bit sad that we have to say goodbye to the old $5 note, but this new one seems pretty cool!

 

I understand how important it is to have these features on the $5 dollar note, without them chaos would happen (fake notes, people not paying the right ones…).

 

2 questions I have are:

  1. How were these features thought of (inspired by)?
  2. What brought attention to this situation?
