K’Nex Challenge

Last week we participated in the East Renfreshire K’Nex Challenge. We had to build a bridge using K’Nex but it had to meet the following criteria:

  •      Be at least 19cm high (the height of a grey K’Nex rod)
  •  Be at least 30cm long (the length of a standard ruler)
  •  Have a strong robust structure to stand on its own.
  •  Be able to support the weight of a small bottle of water.
  •  Be able to open to allow tall river vessels to pass through safely.

At the end we had a secret vote to choose which one we thought met the specifications best. We chose Sean and Gordon’s – well done boys! They will now go forward to the next heat where they will compete with children from other schools. Good Luck 🙂

Here are the final three designs:

This was Shekina’s and Sophie’s, it made it to the final three!




Euan and Ryaan’s was a very close second!
