LETS Swap!

Pokemon cards, Moshi monsters, jelly stickers, friendship bracelets – at some point over the last few years my kids have swapped all these things. And in return they get good stuff back.

Wouldn’t it be great if you could go into a shop and, even if you had no money, you could still swap something you had for something you want?

In communities all over the world, people are doing just that. Or something very like it.

Local Exchange Trading Schemes or LETS for short, enable people who live near each other to swap their skills and receive goods and services without having to pay a penny.

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.

Movie Making Camp for Girls – Camp Reel

Have you ever thought about the people who make movies? Did you know that less that 20% of the main decision making positions in the media are held by women? This obviously affects the way that women and girls are portrayed on screen.

With media platforms like YouTube or Vimeo, its easier to get friends together and write, direct, edit your own shows and distribute them for the world to see, but where do you start? How can you make a movie? One way is to take part in a Apple Camp – check the link to see if there is one in your area.

Once you have been making films for a while, you may want to learn more about how movies are made, and how to put them together. A new venture in California aims to help girls do this – on a one week camp.

Our contributor Annie May had a chat with Esther from Camp Reel to find out more.

3 Tips to Make your New Year’s Resolution Stick!

So the new year has begun and you’ve made a New Year’s resolution. How can you make sure it doesn’t go out the window by February? Perhaps these tips for sticking to your resolution will help…

New Year’s Resolution Tip #1: Be specific

Lots of people give up on their resolutions because they choose ones that are too big, vague and overwhelming. Whether your resolution is to do more sport, be a better friend, take up photography or anything else, you have a better chance of making it happen if you narrow it down.

For example, if your resolution is to be a better friend, make it your mission to remember your friends’ birthdays and to write a card for them, or to ask them often about what’s going on their lives. If you want to get more involved in sport, find out what sports your school or community offers and decide on a class to take or a team to sign up for. That way you have somewhere specific to start!
