Term 4 - Scream Machine

roller coaster(1)

Scream Machine

Roll up, roll up!  You're going on a day trip to a theme park to soak up the unique sights, smells and sounds of the fair.  Learn about the science behind roller coasters and write poems that are shaped as a loop the loop.  Design your own theme park and show your ideas on a digital map.  

Test, testing! Time for some investigations.  Cam mechanisms, pendulums, pulleys and prototypes.  Let's go behind the scenes to see forces at work.  Good news!  The engineers at 'Scream Towers' love your work and want you to build a death-defying new ride for a theme park.  Make a working model and programme it to control the mechanics you have designed using a computer.  

Okay, ready to ride?  Don't forget to scream if you want to go faster!

Fun Facts

  • In the UK, many larger towns host travelling fairs at specific times of the year.  Fairgrounds have a history that dates back to the Middle Ages.
  • Dyrehavsbakken (The Deer Park Hill) is an amusement park near Klampenborg in Denmark, about 10km north of Copenhagen.  It opened in 1583 and is the world's oldest operating amusement park.
  • The human body can handle increased g-forces, as shown in activities including dragster racing, aeroplane acrobatics and space training.  Humans can withstand at least 45g (400 m/s2) as proven by g-force pioneer, John Stapp.
  • In 2010, 102 roller coaster enthusiasts set a new world record at Adventure Island in Essex - the largest number of people riding a roller coaster in the nude!
  • Wooden roller coasters rarely go upside down, unlike steel roller coasters.  This is because wood is not as flexible as steel.
  • Acceleration is measured in g-forces, where 1g is equal to the force of acceleration due to gravity near the Earth's surface (9.8 m/s2).  Some roller coasters have been known to include g-forces of around 4-6 g.
  • The pendulum was discovered around 1602 by the Italian physicist, Galileo Galilei.  During the 17th century, pendulums were mainly used for timekeeping. 
  • The Pleasure Beach at Blackpool had a dodgem-style machine in 1913 called Witching Waves, where a complex arrangement of tilting floor panels created motion.
  • Rides that run with single cars are known as 'wild mouse' roller coasters.
  • In most Latin languages, 'Russian mountains' is the term used for a roller coaster.  Ironically, the Russian term for roller coasters is 'американские горы' ('amerikanskiye gorki'), which means 'American mountains'.  How confusing!
  • In Japan, roller coasters are known as jet coasters.
  • 'The Cyclone' is a historic wooden roller coaster that opened on 26th June, 1927 at Coney Island in Brooklyn, New York.  Reports say that Emilio Franco, mute since birth, regained his voice after riding and uttered his first words: 'I feel sick!'

Letter - join

Welcome to our new handwriting scheme. Handwriting is a very important element of school life, and the associated skills need to be taught carefully. We have adopted the Letter-Join strategy for handwriting across the entire school and cursive script will be taught to everyone. We would love you to encourage your children to practise using the new letter formation! Details of how to download resources are available below.
