The Solar System (BTN Reflection Structure)

Our solar system is a giant place full of stars, planets, moons, asteroids, comets and Earth is just one of the wonders of this giant system.

In our solar system there are 4 terrestrial planets, Mercury, Venus, Earth, Mars that are tiny compared to the 4 gas giants, Jupiter, Saturn, Uranus, Neptune that contain 99% of the mass of all the other planets. Although they are all planets of the solar system they have extremely different temperatures, sizes, weights, moons, weather and don’t have an accurate pattern to where they are spaced. The sun makes up 99.86% of the mass in the whole solar system (the planets make up 0.14% of the mass) and consists of mainly hydrogen and helium and less than 2% of heavy elements such as oxygen or iron. Asteroids and comets and even dwarf planets like Ceres, Pluto, Makemake and Haumea that circle the sun are mostly concentrated into 2 belts, the Asteroid belt between Mars and Jupiter and the Kuiper belt at the boundary of the solar system. What equipment is required to discover all this info about our solar system? What is the progress on learning about the possibility of other life on planets apart from earth?

The Ancient Study of Astronomy (BTN Reflection Structure)

In the ancient time you might think people had no idea about space and couldn’t explain but they actually had pretty good ideas and were very clever when it came to astronomy.

Ancient Babylon was a city/state near what we know now as Baghdad and the Babylonians had a system of writing which enabled them to record lots of  astronomical observations to make mathematical models to create calendars which helped to time business transactions and other important things in Babylonia but Babylon’s astronomical work was influenced by astrology as well. The Maya (group of Mesoamerican Indians) came up with the Mayan Long Count Calendar which used a base number of 20 compared to our current one 10  and because of this they could predict the movements of planets and things such as eclipses. The Ancient Greeks also played a part and an ethically Greek citizen of the Roman Empire named Ptolemy who came up with the Ptolemaic system that proposed Earth was in the centre of the universe was an astronomer that received lots of his knowledge from Hipparchus who was known as the greatest astronomer of Ancient times and creator of trigonometry and discoverer of the wobbling of the Earth around its axis that helps explain the north star will become Vega. Why does the Mayan Long Count Calendar have a base of 20 and today we have a base 10? Are these 3 groups the most important to astronomy? Why/why not? Ancient civilisations have played a big part in the modern understanding of astronomy.

Space Unit Goals Term 4

Space Unit Goals Term 4:

Science Understanding:

Science as a human endeavour

To find out how human’s understanding and discovery has evolved since ancient times about dark matter and its effects.

Earth and space sciences

To find discover what makes our solar system similar or different to the rest of space and its stars and planets?

Extra Goal

To use tables, graphs and other representations to record and present my learning in an organised, neat and clear way that can also show meaningful patterns and connections in data or information.

Semester 2 Goal Reflection

These are my goals for Semester 2:

To make sure I get my homework done, I’ll plan out each week’s homework in my diary. I also want to apply what I learn at school to everyday life. Another thing is to organise my thinking in lessons into a way that is easy to understand and look back on. I think I should work on staying on task in class. I could set limits of things I can say to others. I also want to step up and do things like helping others when they are distracted or doing the wrong thing. This is what a good role model does.

Reflection:

So far I have been getting all my homework done and a big part of that was the way I planned out each week to fit in with my other activities. I have also started to use a new homework planner that helps to specifically work out the times when I do each bit of homework. The only homework I need to work on is my reading. I will continue this homework system and improve the amount of reading I get done.

To apply what I learn at school to everyday life. I have definitely achieved this because any chance I get to use my skills I’ve learnt at school I see it as a great opportunity to improve them. I think I should also when I have time set up some real life problems to solve or maybe just improve my reading by looking at a range of books.

My next goal was to organise my thinking in books that is easier understand when I look back on it. I have not fully achieved this goal but I’m trying to improve it and I’m on my way to achieving it fully. This term I’ll also improve my handwriting with is a major part of this goal. I will always use margins and set out my book to be clear and legible.

I’m very close to achieving this goal but need a bit more work. Staying on task in class is very important. This term I will start being very focused to make sure I don’t miss anything important and know exactly what to do. I have improved a lot throughout the year but it needs a bit more work.

I’ll also work on helping other classmates stay on task as I am a school captain for next year and a school captain should be a great role model. This is an extension on my last goal but is very achievable.
