1) The aim is to design and make a roller-coaster for a marble that will give the marble the longest run off the end! The focus is on: 

 

*The number of turns within the roller-coaster (see detail below) 

*Directional focus as it exits, 

*Ability to enable the marble to run-off as far as possible, 

*Re-usability after each ‘ride’. 

 

2) The marble roller-coaster must be self-assembled and we encourage the use of recycled items.  

 

3) Please use in your model at least: 4 turns for KS1 (Years 1 and 2), 5 turns for LKS2 (Years 3 and 4) and 6 turns for UKS2 (Years 5 and 6).  

 

4) The finished marble roller-coaster (including the base) must not be: 

a) Longer than 50 cm.  

b) Wider than 50 cm.     

c) Higher than 50 cm. 

 

Some possible methods for creating the marble roller-coaster might be: 

 

• Straws to form a track. 

• Kitchen roll/toilet roll innards, possibly cut in half. 

• Egg boxes or fruit cartons to make corners/turns. 

• Pencils to form a track. 

• Knex or Strawbees to form a track, 

• Any other safe method. 

 

The heats will be held in the week beginning Monday 4th March 2023. 

 

5) The final will be held on FRIDAY 15th March 2023.  

 

6)  There will be a winning roller-coaster for UKS2, LKS2 and KS1. There will also be a grand finale at a later date where winners will compare their designs with children from other schools and compete for an overall prize! 

 

May I take this opportunity to wish you every success with your entry.  I look forward to seeing the roller-coasters in action.  Happy designing and happy building!
