Can Too Much Screen Time Damage Your Eyes?

I bet you’ve heard some adults warn that too much screen time can damage your eyes. Some even say that sitting too close to a screen can be harmful. This is an idea that’s been around for decades but is there any truth to it?

In the latest of our Fact or Fable series, Sam investigates.

Exploring Australian Alone

Sally-Anne was out and about in Australian, and took us along on a virtual trip. She shared her first impressions of the country, and then her love of the city of Melbourne.

In this report, she explains why she went to Australia alone, and what it is like to travel without companions.

If you’ve been reading some of my reports from Australia, you’d be forgiven for wondering why I haven’t mentioned any of the people I’m travelling with. That’s because there isn’t anyone, I’m on this trip all by myself. I wasn’t too worried before I came because I’m quite used to doing things alone. I live in my own flat, I went to a different high school to everyone I knew from primary school and I quite often go and visit places by myself, but I’d never travelled alone. In fact, I’d never been outside of Europe at all, even with other people, so the whole trip was a bit nerve-wracking, if exciting.

Lightning Never Strikes Twice

Continuing our Fact or Fable series, today we take a look at the saying ‘Lightning never strikes twice’, with our Science Editor Samantha Gouldson investigating.

Lightning forms when excess amounts of positive and negative electric charge build up in storm clouds. This causes sparks, kind of like static electricity. Sometimes the sparks jump between the clouds but often they jump between the clouds and the ground.

It’s not just thunderstorms that have lightning either; snow storms, sand storms and even the clouds produced by erupting volcanoes can all cause lightning.
