Fact- Around the late sixties the interest in heading to space had sky rocketed. Russia launched the first human to space his name being Yurie Gagarin travelling there in the Vostok 1. Suddenly America took interest it this and launched the first people on the moon. Then they built the international space station (ISS). Now we have so many ideas about space trips like getting humans to mars by 2030 and even filming a reality TV show in MARS. Businesses like virgin galactic and other companies have talked about making commercial trips to space (costing 300 000 to 400 000 dollars).
Question- why haven’t humans started to live on the moon already?
Who’s Idea was it to send people to space?
I now know that people have so many ideas about space travel and we have so many possibilities for what’s to come in the future.
This text was about the solar system:
- There are 4 gas giants and 4 terrestrial planets
- Mars has a mountain 26km high
- Venus temperature never drops below 476 degrees due to its out of control greenhouse affect
- Jupiter is the largest planet with 67 moons and a storm 3 times the size of earth
- Saturn is the second largest and is the least dense of them all
- Uranas is the third largest and but is by far the coldest
- Due to Neptune being so far from the sun a year on that planet is 164 earth years
- The sun is made up of hydrogen and helium
- There are two belts of asteroids in our solar system
How do find out specific statistics on other planets if we’ve never gone there and (other than mars) have no rovers there?
Why is earth and other terrestrial planets so much smaller than gas giants?
I now know many facts about the solar system and understand that its a complicated place and that earth is just like a spect of dust in our Milky Way, ect.
This video was about a rover called curiosity. It was one of the fist rovers landers on mars. It was equiped with drills to take samples from mars’ surface and even a high powered laser. It took 8 months or 200 day to get curiosity to mars, and curiosity had to withstand 16000 degrees during the journey and that wasn’t event the hardes part. The seven minutes of terror was- you had 7 minutes slow down curiosity 20 000 degrees to 0 and safely land the rover on mars in one piece. Australia also had their part to play- satellite disks in Canberra were used to replay files from curiosity as well.
Who designed curiosity primarily?
How many people did it take to complete this mission?
I leanrnt from watching this video is that there are so many things that have to take place before humans can inhabit mars and get rovers there is just a small but important part.
The Babylonians invented one of the worlds first callenders, it was a mathematical model in which they could record huge amounts of astronomical events and was even used to time business transactions. They may have invented theses things, all though they did not do it purely for science, they actually did it for horoscopic reasons.
The mayans where just as Intrested in astrogy as well and had a interest in horoscopes as well. But unfortunately all of their documents and texts were destroyed by Spanish conquistadors. We do know that they created the Mayan long count callender which involved the base 20 number system this meant they could predict the rotation of the planets they used this for horoscopes and astrology.
In Rome a Greek astronomer by the name of tallemy, his most famous work was the Ptolemaic system, it stated that earth was the center of the univer this was proven to be obviously wrong. Also hipparticus ( considered to be worlds most famous astronomer) he recorded many stars and invented the procession of the equinoxes, the term for the earths wobble on its around its axis.
Why did tallemy think earth was the center of the universe?
How did hippaticus discover the procession of the equinoxes?
I know now that we take for granted simple like callenders or simple knowledge about space, and that if ancient astronomers didn’t figure these things out we might not of had callenders ect.
Fact- 2 families in new south wale wher asked to participate in an experiment, it would test their skills and would prepare them If disaster ever struck. In some situations the kids were smarter than the adults, as they stopped them from making huge mistakes. It could have been because they had more experience or were familar with the fact of a natural disaster from school. In the they both made 2 big mistakes when fire/flood waters , got to either off the family’s homes they tried to hide in a room, which means they can’t see what’s happening in the rest of the house.
Question- Why were the parents so frazzled? Which family prepared the best?
Understanding-I now understand that being in a natural disaster of any kind is much harder than it looks.
FACTS- As humans we depend on water, and for most we don’t think about how much we use. For people in Cape Town (experiencing a seemingly endless drought) water is scarce. They only get 50 litres a day that’s barely enough to get you through the day.
- dishes and laundry, 18 litres a day.
- 90 second shower, 15 litres.
- 1 toilet flush, 9 litres.
- Washing your hands, 3 litres.
- Cooking, 2 litres.
- Drinking water, 2 litres.
- 1 dog bowl, 1 litre.
Thats 50 litres gone and if want to have everyday luxuries like a long shower or even going to the toilet more than once a day you’ll be in a predicament.
QUESTION-Who controls the water? Do certain people- like their Prime minister get more water?
UNDERSTANDINGS -I now understand that we shouldn’t take water for granted. And in some countries they barely have enough water to do what we consider day to day things.
Facts- Africa’s recent cracks suggests alarming news- Africa may be starting to split into two. After heavy rainfall huge cracks appeared, supporting the fact that due to the huge fault line through the middle it may split into two in 50-100 million years. It’s more than 15 meters deep and 15 meters wide. It’s growing at a rate of 2.5 centimetres. Rifts like these are the beginning of continental breakup so this theory is very plausible.
Questions- Are there any rifts like this in Australia? Could Australia break apart?
Understanding- I know understand that continental drift is always happening and that fault lines and tectonic plates are very connected to continental drift.
Facts- Recently there have been some major breakthroughs in the meat industry. This is pretty big news as Australia ranks in the top 10 countries that eat the most meat. In labs across Australia, they’ve figured how to make meat without having to harm animals. Basically, they take cells from animal blood and a serum full of nutrients and after a short period of time it should eventually turn into muscle tissue and from there it would turn into meat. But it doesn’t come cheap the first one took 400 000 dollars to make, they say that soon that we’ll be seeing this meat in stores. Although some farmers don’t think its fair to call this meat, meat, as they think it not meat as it doesn’t come directly from meat.
Questions- Who thought of the idea of this type of meat ? Why making meat this way work?
Understanding- I know understand that there is more than one way to make meat and also that there is also vegetarian and vegan options for people who want to eat meat.
