Our bridges
Year 6's DT project in Term 4 was to research bridge designs, then design and build their own to a prescribed set of criteria. We looked at strengthening techniques, trusses, decks and pillars, along with what materials would offer the best support. Their bridge had to span at least 50cm and have a clearance of at least 25 cm to allow boats to pass underneath. The bridges also had to be able to support traffic travelling in both directions. These are some of their amazing results.
