this webinar was about cyber safety.
some things we learnt was that scamming is an important thing to look out for on the internet because there are a lot of hackers that can get into your computer and scam/hack you. 1 thing that they can do is hack into your email. they might and you an email that says you can get an i phone all they need is your bank a count. if you give them the bank a count they might take all your money. they can also put commercials on trusted websites and make you click on them. some strategies you can use to prevent this is to have a stronger password. you could use emoji’s to make it more difficult for the hacker to get in to your email. you could also go onto websites to help you prevent the person. such as ACORN. this website shows you all the latest scams and how to prevent them. lastly i think the webinar had a good structure. they lead it up t a main point and did it a way children could understand. they also used a lot of examples.
this B.T.N was about how long humans have been in space for.
on April 12th 1961 eurika garman was the first man to make it into space. from then the world has changed .the Apollo 11 was the first rocket to land on the moon. on July 20th 1969 the apollo 11 landed on the moon. the 2 first men to ever set foot on the moon were Neil Armstrong and Buzz Oldren. neil armsrons saying was “1 small step for man and 1 giant leap for man kind”.
in 1973 the US made up somethng called sky lab. it was the worlds first space station letting people live in space. in 1981 there was a launch of space shuttle columbia but it used resuable space shuttles. which made the international space station which can be seen with the naked eye.people have been living in it since the yer 2000.
in the future there will be many more experimets in space. including the one that i talked a bout last week in my other B.T.N.
this video was about how space x was planning to colonize mars. Elon Musk told the world his plan for colonizing mars in mexico. people stampeded their way into the room he was lecturing in.
he told us the first step was to build a rocket ship. first the rocket will be launched into earths orbit because of a big rocket booster. when completed this rocket would be stronger than NASA’s strongest and heaviest rocket SATURN V. the rocket would be powered by 42 raptor engines which is the new better engine that space x has been working on. this rocket runs on methane but you will only find out why later.
so the rocket is launched into the earths orbit with the booster and then the booster with separate from the rocket and come back down to earth. when the booster comes down to earth and quickly gets ready to launch a propellant tank. that tank then docks with the space ship filling it with the gas it needs to mars. musk said it might take 3-5 propellant tank to fully fill the space ships trip.
then the rocket is off t mars. the rocket lands by using its engines to lure itself to the ground. its a technique called supersonic retro propulsion. after letting out the passengers the space ship eventually lift off and come back to earth. where will it get the fuel for that? you might wonder. well hey get it o mars space x is using methane because it can be made from the planets atmosphere.
now my only question is that how will they survive. because mars is even worse than Antarctica. you don’t have food or water in both places but at least in Antarctica you can actually breath. and in which habitats will we live in. also when you go to the moon you get muscle loss. imagine in mars.
i understand that there is not enough room n earth and that people will in the future have to start moving to different planets a the moon.
