As part of the DT the children in year 5 had to create a bridge after researching what made a bridge effective and fit for purpose. All children were given the same materials and time to create their bridge. After the first attempt they drew their bridge and wrote an evaluation. Using their evaluation they made improvements to their bridges with regards to making them stronger and more stable. The final assessment was to test the strength of the bridges. The strongest bridge held 15 pairs of scissors.
