BTN-Mars Experiment

BTN-Mars Experiment

Facts- There was an experiment to see how Mars explorers would react to challenges they would when on mars. So NASA threw six people into a dome in a side of a volcano in Hawaii to do a isolation experiment. The dome was built to give a sense of what it would be like on Mars. Things that we’re used to every day will not be available to them like fresh water, air and privacy.  They need to know how people deal with it which is estimated between  1 and 3 years. Everyone is taking the experiment seriously so if you wanted to go outside you’d have to wear space suits.

Questions- When will send people to mars will they stay there forever?

How many people will they send to mars?

Understanding- Now I understand how different the conditions are from Mars and Earth and how much harder it is to cope with these conditions.

This video was about the mars rover curiosity. NASA landed it on space but it was a tough journey. It took eighth months for the rover to reach only earths neighbouring planet and ts shields had to survive 1600 degrees as it slammed into Mars’ atmosphere.  Then there were 7 intense minutes of slowing down to find a spot to land and thousands of keys to press. If something went wrong millions of dollars and years of work wasted. Curiosity wasn’t NASA’s first rover on mars but it’s definitely the best. It needs to roam around mars taking samples of rock with lazers. The aim is to learn more about what mars is made up of. But we’re also looking for signs of life. Mars is the most like Earth of any of the planets in our Solar System. Scientists think that Mars may have once been home to some sort of life form. There’s even the very slight possibility that, just maybe, some tiny thing is still living there.

How many more rovers are NASA planning sending to send up?

What are the jobs of the over rovers?

I know understand that there are many things that we have to take into account before living on another planet even the small things help like the mars rovers.

The Ancient study of Astronomy Reflection

The Ancient study of Astronomy Reflection

Our video this week was about the study of astronomy and the fascination of the space between cultures. The Babylonians were very advanced astronomers in their time because of their system. They had created a system of writing so they could record astronomical events from which they created mathematical models. The models led to creating calendars which then led for them to be able to time important events like business transactions. They didn’t do this for purely scientific understanding but Astrological influence.

The Mayans created the Mayan long count calendar. There are a lot of the things we don’t know because the spanish conquistadors burned their work. The Calendar worked on a very sophisticated number system based on 20 unlike today where we use 10. Their number system and Astronomical observations helped them see rotation of planets and eclipses.

In Ancient Greek the Tolemy who created the Ptolemaic system it was theorized that the earth was in the center of the universe. It influence astronomical knowledge for hundreds of years but it has been disproven.  Tolemy got his knowledge from Hiparticus as mathematician known to be the father of trigonometry. He also discovered the precession of the equinoxes which is the wobbling of the earth on its axis.

 

How did the Tolemy get the theory of the earth being in the center of the universe?

Did any of these cultures get ideas off each other?

 

I know understand that if  Astronomers and other people didn’t discover these things and tell the world about them the earth would be very different and would not understand what we know about space today.

BTN-Don’t Panic

Can you imagine being a Natural disaster, how would you react? Well, two families were put to the test and were helped by some experts, special effects and more. The first family to be put to the test is the Matthews they are facing a bushfire. The second family is facing a cyclone. Both of these recreations were to see how families react when a disaster hits them. By the look of things, the children are doing better than the parents. They reckon that they weren’t really ready and they think the same for a lot of other families. It’s important to have a plan and know it well in case of an emergency. Everyone should have a role around the house and you should practice it as a family.

I know understand that we should all have plans in case of a disaster and know it well.

Could they try more around the country with different disasters?

 

BTN-Cape Town water crisis

BTN-Cape Town water crisis

Just to see the slightest bit of rain is enough to get people over there excited. Capetown is a city down the bottom of Africa, but for the last few years, they’ve been in a drought. But in the last few months, it’s gotten a whole lot worse. But even a little bit of water won’t help out the situation.  Authorities predict that the taps will turn off on June 4th, the call it day zero. In Australia, we’ve experienced restrictions but there’s is a whole other level. They only get 50 liters a day since February 1st. That doesn’t give you much because of stuff like laundry, dishes, and toilets all that is already 27 liters. If day zero arrives then people will have to start to walking to collection points to get 25 liters of water. The restrictions have made a difference pushing day zero further away.

I know understand the difficulty of not have water and the struggles that it causes as such a necessity.

How long till they run out of water?

Will the restrictions get tighter?

Herald Sun- Is Africa splitting apart

Herald Sun- Is Africa splitting apart

Facts-There have been massive cracks in a valley in Kenya. Is Africa splitting apart? Some scientists suggest that it’s actually splitting apart. The rips are growing deeper and longer as the time passes. Scientists believe that this crack will develop over time. They think in tens of millions of years Africa will be split in half. People first saw it after very heavy rainfall in Kenya. That rainfall caused a lot of damage like flooding areas and walls collapsing. Those waters created 7km long rips in the earth, it ripped a highway open and homes and cars got pulled down. Experts say that in about 50 million years, the African continent will split into two with the Somali tectonic plate.

Understanding/wonder- I wonder how this will affect Africa in the future

Question- When they do split apart will they have 2 separate names?

 

 

 

BTN- Hawaii Volcano 2

BTN- Hawaii Volcano 2

Facts- For the last few weeks lava has been continuously flowing on the streets. It doesn’t move fast but it destroys everything in its path. Kilauea is one of the worlds most active volcanos and it’s partly why Hawaii is here today. Hawaii is a hot spot volcano. They form over a place where rock or magma has built up under the earth’s crust. When there’s enough pressure a volcano forms but when it hits the water it cools down and becomes solid forming new islands. The hotspot will always stay in the same place but because of tectonic plates which are always moving, it pulls the islands away from the hotspot gradually. That’s why Hawaii’s group of islands look like that. Kilauea has been erupting continuously since 1983. But this is the worst it’s been for a very long time. And more people are getting worried that as the lava drains out the volcano it’s going to get even more dangerous. Because the molten rock will heat up the water and will produce steam which could cause the mountain to explode.

Understanding- I know understand that Hawaii is a hotspot volcano where it builds up magma and when enough pressure it forms a volcano.

Question- How far have the islands moved since created?

BTN-Hawaii Volcano

BTN-Hawaii Volcano

Facts- People of Hawaii been running away as the Kilauea volcano spilt lava and land fountains of toxic gases into the streets. It already destroyed 26 homes. Few people were allowed to go back and collect valuable items such as pets and medicine during hours where the volcano was not very active. But others were not allowed to travel back to their areas because it’s consumed with poisonous sulphur dioxide gases coming out of the earth. Those visits back were well timed as the night after more lava came out from fissures which are slits and holes in the earth. So far no one has died or been injured by this volcano but it had a strong magnitude of 6.9 it was the strongest earthquake since 1975.  This caused rock slide and a coastal cliff to come down collapsing. Scientists predict more earthquakes and eruptions to happen in the next few months. Most of the activity is happening in Leilani Estates and Lanipuna Gardens areas. Kilauea has one of the most active volcanoes in the world. It has been erupting constantly for 35 years. Most of their eruptions are effusive eruptions they flow continuously but don’t explode.

Understandings- I understand the effect it has on areas, things that some volcanoes can produce and types of eruptions.

Question- How many eruptions have there been?

BTN-Queensland Drought

BTN-Queensland Drought

Facts- A drought is where there little or no rain and it’s hard for farmers to feed animals and grow crops. It’s not called the sunshine state for nothing it’s always hot, dry and sticky out there. Angus and Lochy are 2 of many kids living in the Sunshine State. They have cattle, horses, and chooks but it’s a little harder to get to things out there like school and swimming lessons. Just imagine for us it probably only takes us 5-25 minutes to get to school and for some kids, it take’s 2 hours. Now 90% of Queensland is declared in drought, that’s the most widespread drought in the state they’ve ever recorded. Which makes things a little more complex so  Queensland state government will soon be giving farmers help until the rain comes back again.

Understandings- I know understand that it’s hard for people who live in hot weathers and their struggles. I also understand that it effects there animals and pay.

Questions- How come not much rain comes to Queensland?

BTN-The Ring of Fire

BTN-The Ring of Fire

Facts- On September 29th, 2009 at 7 am a huge group of massive ways tore through coastal villages in Samoa. Turning so many homes into rubble. Its cause was a massive earthquake on the sea floor near the coast of Samoa. The very next day another huge earthquake hit the Island of Sumatra. There about 10 000 kilometres away from each other, scientists say it’s unlikely they caused each other. There have been smaller earthquakes and disasters there in the last year. And almost 90% of earthquakes happened in that broad area, it’s called the Ring of Fire. Some of the largest earthquakes happen there like the tsunami in 2004 happened in the Ring of fire. It’s home to 3 quarters of the world’s volcanoes and some of the biggest eruptions. We live on the thin cool layer the crust but it’s not just one solid piece. It’s made of huge pieces called tectonic plates and quite a few go along the Ring of fire. Tectonic plates drift over the liquid rock and slowly over time change shape. Scientists think that millions of years ago they caused the change of the continents. But you can’t see it move because it grows and the pace of your fingernail. Volcanoes can happen this way too.  

Understandings- I know understand about tectonic plates, what they do and their effects. I also understand that so many people live there that we need to find out more about what’s happening below.

Question- How many plates are there?
