Space Reflection- A real life scale of the solar system

This video was about our solar system on a scale that is more accurate than the ones on the internet. The solar system is a lot different by size than what we can see from earth. When you make a model of the planets you need to have at least 7 miles ( approximately 11 km) of land. All of the planets shown in the video take a different amount of time to orbit around the sun. I now understand that there is more of a difference of space between the planets than it shows in the not accurate models. Why did they make the models on the internet not accurate? Does our earth really look like a tiny marble in all of our solar system?

Teaching astronomy and space 321 reflection

This video was about how humans grew to understand more about the solar system and also about our galaxy and the cosmos. The ancient Greeks thought that the sun and stars had to be moving and not the earth otherwise we would have felt it. The Greeks drew the solar system as the earth in the middle, then the moon opposite it and then the sun opposite the moon. And then the stars all rotating around the earth in a circle. Then one day they found that something didn’t move in a circle but back and forth so the Greeks model had to change. Then astronomers developed more complex models with even more circles.  Then one day an even better model was formed when astronomers put the sun in the middle of our solar system. Mars was actually the thing that moved backwards and forwards across the night sky. Then one day Galileo built the telescope when people finally found out about the actual representation of our solar system. Now in the current model all of the planets orbit around the sun and this meant that if the sun and stars moved across the sky then the earth must be rotating. I now understand about how people grew to learn more about the solar system and how the models of the solar system changed over time as we grew to learn more about space. How did people even first think about space when they weren’t 100% sure it existed? Why did people start getting interested in space and astronomy?

BTN- Humans in space

This video talked about how humans have increased their knowledge about space by going into space. Neil Armstrong and Buzz Aldrin were the first astronauts on the moon. People are thinking about getting people to live on mars for their lives for a TV show. Some space companies actually have space tours if people want a turn to be in space. I now understand that our knowledge about astronomy and space has improved a lot and how we are still trying to discover more. Are astronomers completely sure that mars has the correct requirements to live there? When do astronomers think they will start sending people into space?

BTN- The future of space exploration

This video showed how we might be living on mars in the next 40-100 years. When this all starts there is a spaceship with 450 tons of cargo for mars, this spaceship will be launched into orbit with a massive rocket booster, when this is completed this rocket will be much bigger than NASA’s ‘ Saturn V’ rocket. The rocket would be powered by 42 raptor engines, space X did their first test of the 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 its 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. Why did astronomers choose mars to be our future home? Do astronomers think that in the future people would be able to deal with moving to mars one day?

space food

This video was about how it’s a lot harder to eat food in space than on earth. The food comes in wrappers or boxes to stop them from floating around. You need to use straws to eat somtimes. The drinks come in a slip and you need to drink them with a straw. I now know that it is harder to eat in space than on earth. Do astronauts get nutrition when they are eating in space or not? If you had a water and it was in space, would it float?

BTN- Space Rock

This BTN talked about rocks in space. It talked about the different rocks like meteors ( Meteorites, Metoroids) , Comets and Asteroids.

Recently there was a massive meteor explosion over Russia, the meteors force was 20 times bigger than an atomic bomb. That same day astronomers watched an asteroid make its way past the earth, it was close to hitting the earth. The solar system doesn’t just include planets and stars, there is also dust, rock and ice. They are the leftovers of the supernova that formed the planets billions of years ago.

COMETS:

Comets are chunks of ice and dust that come from the cold outer parts of the solar system. When they get closer to the sun they melt and give off gas that down on earth we see as an amazing, glowing trail.

ASTEROIDS:

Asteroids are usually made of rock or metal, a lot of asteroids lie in the asteroid belt in our solar system, but some travel closer to earth.

METEOROIDS:

Meteoroids are smaller chunks of asteroids, and millions of them enter the earths atmosphere everyday, when they do we call them meteors.

I now know the difference between comets, asteroids and meteoroids and how they all are important in our solar system.

When did the first meteor hit a country in earth? Who first discovered what these space rocks were?

BTN- Our solar system

This video talked about the planets and other objects in our solar system. There are 8 planets ( Mercury, Jupiter, Mars, Saturn, Uranus, Venus, Neptune, Earth). The terrestrial planets are made up of Mercury, Venus, Earth and Mars. There are also 4 gas giants Jupiter, Saturn, Uranus, Neptune. I now understand the different objects in our solar system. What objects do other solar systems have? Do all Galaxies have planets?

Space- Science Goals

Science Understanding

                             

  1. Science as a human endeavour

I would like to find out how parts of the solar system were discovered    and about the distance of the earth to the solar system and if it affected the way people thought and understood about space and the solar system.

 

  1. Earth and Space sciences

I would like to learn about how the solar system obits around the sun and what planet obits around the sun first then what planet orbits last. Are all parts of the solar system important because if we took a planet out would it affect the solar system drastically or not so much.

 

  1. What more do you want to get better at

I want to get better at summarising my notes when we take notes on the space videos and using things like the equals sign when taking a note instead of writing it down fully e.g. sun= star.

Space- The ancient study of astronomy

Space Video

This video talked about how far back in history Astronomy has travelled and the ways that we talked about astronomy then and still use that way now. The ancient Greeks, the Babylonians and the Maya all discovered amazing things about astronomy and have made how we understand space now a lot easier. The Babylonians were very advanced astronomers because the Babylon’s had a system of writing so they could write down a lot of information about space, and they made mathematical models like calendars and they could be used for very important times in Babylonia. The Mayas created something called the ‘ Mayan Long Count Calendar ‘ , they developed this by using an extremely hard number system that used the base of 20, other than now how we use the base 10, this let them predict the motions of the planets and other things like eclipses. In Greece there was an astronomer called ‘ Tamale ‘ who invented the ‘ Ptolemaic System ‘ , this model showed how earth was in the complete centre of the universe, this has influenced humans for hundreds of years. I now know that astronomy was not a recent thing and that how we live, and know about space now all depended on the people in the past who discovered all these things rather than the people in the present. Something that I’m wondering is that are there people that influenced our knowledge of space alive, or did all the people that figured things our live in the past? I’m also wondering if did any other culture apart from the ancient Greeks, The Babylonians and The Maya find out interesting facts about space? Astronomy is still a big thing that people are trying to discover but all these people that found out these amazing things in the past really influenced how we think about space today.
