2. The Buzz – Science news delivered to your inbox…

It’s conker time again! Have you found any big ones? Did you know that horse Chestnuts are more often called ‘Conkers’ except in the USA where they are called ‘Buckeyes’? The “horse” connection is twofold: (1) Horse Chestnuts were fed to horses in the East as a stimulant and to make their coat shine. (2) The leaf-scars on the twigs have the shape of a horseshoe, including the nail holes. Check it out next time you get the chance!

Click here if you want to know more about conkers including some handy tips for playing conkers.

If you’re around and about in Ashton, Northamptonshire this Sunday 8 October - don’t forget to pop down to the World Conker Championships 2006 which starts at 10.30am.  You could be crowned Conker King (or Queen)!

Are you always being nagged at for playing on your computer games?  Well good news. Research has found that as well as being fun, games can teach you stuff and help you learn. The study found that games could help change the way you think and talk. It also discovered they can help you learn how to solve problems. Pupils who tried learning using games were found to improve their skills a lot more than those who didn't. A recent survey found six out of 10 pupils said they'd like to use games in class and nearly the same amount of teachers said they would support it. But what if your teacher likes it so much he won’t let you have a turn?

Have you heard about Timmy the cat? He’s grown so big he has to sleep in a kennel at night! He truly is a massive moggy, a colossal cat, a phenomenal feline! The black and white pussy only eats a can of cat food a day but still weighs a whopping 10kg (22lb) - which is about the same as a two-year-old child. It's thought Timmy, who was adopted from an animal shelter, has always been large and is simply "big-boned". Well we can’t all use that excuse unfortunately so switch off your computer game and go for a game of footie!

3. Crash Bang! – Exciting experiments for you to try at home…

Spinning Juice

Finished your drink of juice?  Great! No don’t throw away the empty carton!  Here’s something fascinating….

Ask an adult to help you.

You will need:

  • empty 1 litre fruit juice carton
  • piece of string
  • pair of scissors
  • washing up bowl
  • water

What to do:

  1. Poke a hole in the bottom left hand corner of each of the four faces of a 1 litre juice carton.  (An adult should help you with this)
  2. Poke an extra hole in the top flap of the carton and tie a string through it.
  3. Hang the carton from the string.
  4. Pour some water into the washing up bowl so that it is about one quarter full.
  5. Place the carton into the bowl of water.
  6. Pour water into the carton until it is full to the top.
  7. Now lift the carton out of the water by the string and watch what happens. It starts spinning around! Sing it Kylie!

What’s going on?

Newton's Third Law says that every action has an equal and opposite reaction. So when you push on something it pushes back on you. Water shoots out the holes, and pushes back on the carton with equal force. A turbine is formed as the energy of the moving liquid is converted into rotational energy. Consequently the carton spins. This effect was first noted by Hero of Alexandria.

Hero (or Heron) of Alexandria (roughly A.D. 10 to roughly A.D. 70) was a Greek engineer. His most famous invention was the first steam engine, the aeolipile. Steam was generated in a separate boiler then fed into a sphere through a hollow spindle. The steam left the sphere via two narrow, angled nozzles and the reaction to the jets of steam leaving these nozzles made the sphere spin. To understand it better, see the animation of Hero’s Aeolipile.
