Term 2 Showcase

On June 29 2015  was syndicate 4's showcase. Rooms 17, 18, 19, 20, 21 & 22 did their own projects and writing  for the showcase, in my class the theme was The Solar System. Preparing for the showcase was a bit tough but we got through it. My project was shared with Alex and Kathrin. here is a picture of our project.

We also had to do an explanation for the showcase and here is mine.

Why Do The 8 Planets Orbit The Sun?

Why doesn't Earth and the other planets bump into each other in space? What makes all the planets orbit the Sun?

A very long time ago when the sun was young it had a rotating disk made of dust and gas. As the years went by the dust and gas from the sun’s disk ended up forming the 8 planets in our solar system. The planets inherited their motion from the sun’s rotating disk. While the planets were being formed they were also circling the Sun, like racecars on a track.

The gravity in the Sun’s atmosphere is what pulls the planets to orbit the sun in the same clockwise direction 24 hours a day and 7 days a week. All of the planets have this invisible path to follow.

Each planet takes a varying length of time to orbit the Sun.  Planets further from the Sun than Earth take longer to orbit the Sun.  Planets closer to the Sun than Earth orbit the Sun quicker. Earth takes 365 days to orbit the sun, that is how we get our year.

The sun is in the centre of our solar system.  Earth is the only planet with life, because of our perfect conditions. If Earth was any closer to the Sun water would evaporate, if Earth was any further away from the Sun, the water would freeze so Earth is in the perfecter place in the solar system.

Explanation Writing

In my class we're learning to write the structure of an explanation. We did our first explanation on the Aurora Australis which means the southern lights. Here is my published Explanation.

The Aurora Australis

Have you ever witnessed nature’s light show dancing across the night sky? This colourful display is often referred to, and known as ‘The Southern Lights’. What causes this spectacular illumination, Aurora Australis?

The Aurora Australis starts all the way up in space at the sun, the sun is always active and it ejects a cloud called a solar flare which is filled with ions, electrons and atoms.  The sun has several solar flares a day.

Then, the solar flare heads towards Earth. The particles in the solar flare are dangerous to humans but there is something that saves us, it’s in Earth's atmosphere. it’s Earth’s magnetic field. It acts as a invisible shield. The magnetic field saves us from the dangerous particles. The solar flare follows the shape of the magnetic field and it directs the ions to the North and South Poles. That is when they pick up speed, on it’s way to the North and South Poles. The particles in the solar flare collide with all of the other particles.

After that, the solar flare releases energy in the form of light. The different ions make the different colours of Aurora, green is the most common colour. You will be able to see Aurora on a cold, dark winter night if you are close to the polar regions.  Aurora is also in the North Hemisphere it is called Aurora Borealis but the Southern Light is much bigger and brighter than the Northern Lights because more ions go down to the South pole.
