Y5 Bridge Making

For their DT project, Y5 researched bridges. They looked at drawbridges, vertical-lift bridges, curling bridges and many more. They considered how the bridges moved then learnt about cross sectional diagrams before designing their own bridge. The children then worked in groups to make a bridge that fit the following criteria:
Must be sturdy and stable
Must be symmetrical (except winch system)
Must be moveable
