MODEL ART STRAW BRIDGE PROJECT - PAGE 3

V. Ryan 2004 - 2009

 

Finally, join the two sides together using short pieces of straw (approximately 80mm in length), fixing them with sellotape.
The bridge is now ready for testing with weights.

 

When fully constructed the art straw bridge will be quite strong although it will move side to side.
To hold in a fixed position, the bridge should be supported on either side. Weights can then be added until it collapses.
If a class is attempting this exercise it may be a good idea for the pupils to work in pairs.

   

 

   

   

The bridges constructed by a class can be tested and the data collected (number of weights successfully supported). This can be presented in the form of a table and a graph or pictogram.
