What causes night and day by Dion


Why do we have day and night?


Night and day is caused by the earth's rotation on its axis. The earth takes 24 hours to make a complete turn. When one side of the earth faces the sun this part has day the other half of the earth facing away from the sun have night.


The sun is the source of light for day. The sun does not move it seems to move across the sky starting in the east in the morning moving toward the south at noon and then toward the west as the day ends. It is the earth turning that makes it seem as though the sun is moving.


In conclusion, night and day is caused by the earth's rotation on its axis not the sun's rotation.

All about Astronomy
Sun
Our sun is a star located at the center of our solar system. It is a huge, spinning ball with hot gas and nuclear reaction that light up the earth and provides us with heat.The sun’s core has a tremendously high temperature which is roughly 15 million.


Moon

The moon is Earth’s only natural satellite. The moon is a cold, dry orb whose surface is studded with craters and strewn with rock and dust (called regolith).



Solar system
Our solar system is located in the outer reaches of the milky way. The milky way contains roughly 200 billion stars. Most of these stars are not visible from earth. Almost everything that we can see in the sky belong to the Milky way or the galaxy.

Comets
A comet is a loose collection of ice, dust, and rock particles typically with a long, narrow orbit.
Comets have different colours including silver, blue, purple and gold at the end of their trail. Comets are usually blue or white at the front part. The color of the comet depend on its distance from the sun.

Planets
There are 8 planets in the solar system - Pluto is now a dwarf planet taking us down from 9. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Uranus.

Organising my ideas for writing by Andrea


We have been using Popplet to do our planning on.  This helps us a lot with our writing and it is better to use Popplet for our brainstorms.  It is also a very helpful website for us Room 10 students.
