Aurora are colorful lights in the night time sky primarily appearing in Earth's polar regions. But what causes them? The culprit behind aurora is our own Sun and the solar plasma that is ejected during a magnetic event like a flare or a coronal mass ejection. This plasma travels outward along with the solar wind and when it encounters Earth's magnetic field, it travels down the field lines that connect at the poles. Atoms in the plasma interacts with atoms in Earth's upper atmosphere.
This video shows a comprehensive description of how an Aurora occurs and diagrams of the process that causes us to be able to see it in the Northern and Southern hemispheres. It is age appropriate and of educational content from a reasonably authoritative source. The video is 3 years old and the information contained in it is still current and relevant.

This is an excellent link to the Australian Antarctic Divisions information page on Auroras.
It includes basic information on auroras, colours in auroras, shape of auroral forms, height of aurora, intensity variations and the aurora and Tasmania with a video concluding the page.
