Facebook For Kids – Good or Bad?

Do you use Facebook? While it is officially banned for under 13 years, a survey last year showed that almost half of Britain’s pre-teens have a Facebook account. Joanna Bradey tells us what she likes about Facebook.

 

Facebook: What’s it all about?

 

Facebook is a website created in 2004 by a US college student Mark Zuckerberg. It started off as a way of college students to network with each other, which quickly spread throughout the world, and now has millions of members. Facebook works by people registering and creating a profile for themselves, and then becoming ‘friends’ with other people. A user can update their status to let their friends know what they’re up to, upload photos to share, send private messages to each other, and play games.  You need to be at least 13 years old to be a member, and Facebook is banned in some countries altogether, like Syria and Iran.

The thing that I like about Facebook is that it is a quick and easy way to keep in touch with all those people I have met in real-life but don’t have time to write to or call them, like old workmates or family that have moved away. I can upload a photo and anyone I am friends with can see it, and comment on it. In the days before Facebook, if I wanted to share a photo with everyone, I would have to print out lots of copies and send them in the post, which is very expensive and time-consuming. Since I joined Facebook, I am better at communicating with people and I enjoy seeing what all my friends and family are doing. I think that I know them better and it’s easy to keep-in-touch.

What is Juno?

There has been a lot of excitement about the Juno probe this week, but what is it and what is its mission?

What is Juno?

Juno is a spacecraft designed and operated by NASA, the US space agency. It was launched from Cape Canaveral on the 5th August 2011 and has taken almost 5 years to travel the 716 million kilometres to Jupiter, the largest planet in our solar system. Juno is 3.5 metres in height, and when its solar arrays are extended it’s more than 20 metres across. These arrays are covered in more than 18,500 solar cells, which allows Juno to operate even when it’s at such a great distance from the Sun.

Why is it called Juno?

In Roman mythology Juno was the Queen of the gods. She was married to the king, Jupiter, who wasn’t always well-behaved. Juno had to peer through the clouds to discover what he was up to; the spacecraft is called Juno because it will be looking beneath the clouds that cover the surface of the planet Jupiter.

Aboard the Juno craft are 3 models of Lego minifigures: Jupiter, Juno and Galileo, who discovered in 1610 that Jupiter had moons.

What is it looking for?

Jupiter is enormous; it’s two and a half times larger than all the other planets in our solar system combined. It’s made entirely of gases and is believed to have no solid surface. The planet rotates at an immense speed, completing one rotation every ten hours, and telescopes have shown us that it has a cloudy atmosphere with colourful spots and stripes. The largest of these, known as the Great Red Spot, is a storm that is several times the size of Earth and has been raging for more than 300 years.

This mission is the first time that humans will be able to glimpse what lies beneath Jupiter’s cloudy atmosphere. The main objective is to understand how the planet formed and evolved, which will give us more information about the formation of gas giants as well as the rest of the solar system. Juno will also measure the quantities of water and ammonia within the atmosphere, examine the magnetic field that surrounds the planet, observe any polar auroras and measure the gravity to see whether a solid core may exist after all.

For more information about the Juno mission you can watch this video from Nasa, and have a look at the Juno mission webpage.

What is the Big Deal About Finding Richard III?

As skeleton found under a car park in Leicester has been identified as that of King Richard III, who ruled England from 1483 to 1485. Richard has been pictured as a tyrant king. There’s a story that Richard killed his own nephews, the legendary ‘princes in the tower’ in order to usurp the throne.

Nearly a century after Richard’s death, Shakespeare describes Richard as a ‘bottled spider’, a hunchback. Since Shakespeare’s time writers and artists through history have imagined Richard as a terrifying figure, whose physical disabilities are signs of his cruel inner nature.

Some historians argue that Shakespeare must have been writing propaganda to please his queen, Elizabeth I, whose grandfather Henry VII defeated Richard in battle. These historians argue that Richard’s ‘hunchback’ is an insult made up by Shakespeare, but until now, we haven’t been able to know what the truth is.

Things that make you go poo….

After talking about bones in my last article, I thought I’d go on to talk about poo, or at least how it’s made.
I like eating. I think a lot of people do. Biscuits are a particular favourite…chocolate Bourbons especially. But how do we get from biscuit, or apple, or stick of celery to the brown stuff we call poo.
Well, it’s thanks to the digestive system, which starts at the mouth, and runs all the way to our bottoms. So let me take you on a guided tour.
