Teachers at Brisbane's St Pauls college Bald Hills are using innovative techniques to make military history come to life for their students. 

History teacher Kerry Daud came up with the idea five years ago to build a 27-metre long trench to teach students what life was like for soldiers in world war 1. 

Ms Daud said that it has taken many years to come into fruition and it has changed both the teaching and learning experiences for all at the school.
