This video was about the solar system. It mostly covered facts about the 8 planets like how many moons they have, the extreme temperatures, how big or small they are, their atmosphere and much more. It also talked about asteroids and satellites. The video was packed with information and answered many of my questions I had about our solar system.

FACTS-

  • Jupiter is known for being the biggest planet in our solar system. It has a total of 67 moons and consists mostly of hydrogen and helium. Even though it is so much biger than earth it is considered tiny compared to the sun which takes up 99.86% of the mass in our solar system.
  • Neptune is one of the very cold planets and one of its years takes 164 earth years. It has 4 moons. It neighbouring planet, Uranus, is also quite cold and quite small. It has 27 moons.
  • Venus is the hottest planet and can be quite visible from earth. It has no moons. We are its neighbouring planet and we have one moon, mars is then next and it has 2 moons. I also learnt that there are 2 types of planets, terrestrial and gas giants.

QUESTIONS-

  • Why do planets have different numbers of moons and why do the biggest planets have the most moons?
  • When were the facts about our solar system and its planets discovered and who discovered them?

Understanding-

  • I now understand a lot more about the planets in our solar system, the differences between other planets and earth and why many people are interested in this topic.

Purple- Questions        Black- Understanding

 

This BTN was about how to cope in a natural disaster. They had 2 families put in a fake disaster and would see if they prepared correctly. The first family was in the scenario of a bushfire. They were off to a rough start but came to their senses and did what was expected: tape windows, fill up bath etc.

The second family was in the situation of a cyclone. Unlike family 1, they followed instructions from the start that included taping windows, making sandbags etc.

 

  • In the 2nd family, the kids actually knew more than the parents
  • The 2nd family kids stopped their parents from making a bad decision
  • The first family made a huge mistake because there was a fire in the kitchen and they locked themselves in the laundry.

 

  • Why did they tape the windows?
  • How did the fire spread to the house?

 

  • I now understand how dangerous natural disasters can be and how hard it can be to know what to do that situation.

This BTN was about a drought in a town in south Africa called Cape town. They have been experiencing any ordinary drought though. One member from each household has the opportunity to collect 50 litres of water each day in the middle of town. Now,  50 litres may sound  like a lot but it is used for toilet flushing, showers/baths, washing dishes, drinking and pet drinking.

  • For a 90 second shower, 15 litres is used
  • At one point, cape town had to lower the 50 litres per day to 25 litres
  • Cape town has been suffering in these conditions for 2 years

 

  • How bad has the drought gotten over the years?
  • When did the drought start and what was the first limit of water per day?

 

  • I now understand how bad droughts can get, how much people suffer and what awful circumstances they are in.

This BTN/ Herald sun was about the mysterious crack appearing in Africa. The crack is located in the middle of the valley in Kenya. Scientists believe the crack indicates a separation of Africa. Many tourists have begun taking photos in front of the crack.

-Geologists believe the huge fault line is evidence the African continent will break apart over the next tens of millions of years.

-It became exposed for the first time after heavy rainfall in Kenya in the past month which also caused hospital walls to collapse, flooded entire neighborhoods, and closed off major highways.

-The crack is more than 15m deep and 15m wide.

 

 

-Will the crack cause any natural disasters like a volcanic eruption, earthquakes, tsunami’s etc; when it grows bigger.

-How did the crack appear and who discovered it?

-I now understand all about the strange crack in Africa, certain people’s beliefs behind it and some of the damage it has caused.

This BTN was about The Ring of Fire. The Ring of Fire is an arch of countries where big earthquakes happen. In 2009 September 29-30 2 of the worlds biggest earthquakes happened in two very different, far apart countries. Scientists were trying the work out whether it was a coincidence or it was connected in some way.

  • The two countries were Samoa and Sumatra and are 10 000km away from eachother
  • Some other countries in the Ring of Fire are Japan, USA, Mexico and Chile.
  • The biggest earthquake was the 1960 Valdivia earthquake(Spanish: Terremoto de Valdivia) or Great Chilean earthquake (Gran terremoto de Chile) of 22 May is the most powerful earthquake ever recorded.

 

  • Why are some earthquakes much worse than others?
  • How do scientists discover the reasoning behind earthquakes?

 

  • I now understand how bad earthquakes can actually be, some of the worst ones that have happened and why they are terrible.

Recently in Australia we celebrated ANZAC day. ANZAC day is when we celebrate and commemorate the soldiers who fought in war against Gallipoli and sacrificed their lives for our country. This BTN was about an aboriginal boy named ANZAC. He is the 5th ANZAC in his family, named after his great, great grandfather. His great, great grandfather is the son of the hero in their family. Arthur ANZAC’s great x3 grandfather. Back when Arthur was alive aboriginal’s weren’t allowed to be apart of the army but Arthur was determined. He fought against Gallipoli and was one of the few that survived. His next war was against France. He sadly died and the family wasn’t notified until much later. 2 months ago ANZAC and his father were given Arthur’s medals that had been lost for decades.

 

  • Arthur was enlisted in the army in 1916
  • The date of the Gallipoli landing, the 25th of April, became known as Anzac 
  • In aboriginal culture, you must be buried once you died where you were born.

 

  • Why is it called ANZAC day?

This BTN was all about Stephen Hawking and some of his discoveries, flaws and recent death. Stephan is/was the smartest person in the world. He was known for physics and science. He mostly thought about and discovered space, black holes and how our universe started. When 21, Stephan was diagnosed with Motor Neuron Disease. He showed resilience and still continued with his studies and dreams.
