Leonardo da Vinci designed a bridge around 500 years ago! It is still used today to make a great many structures as well as bridges. The design is clever because it is self-supporting; this means that no fixtures or fittings are needed to hold the frame together - the added load and gravity hold it together! Can you make one?
You are in a remote location with only lengths of timber to use.
You have no rope or materials to fix the timber together.
The bridge you make must be self-supporting in every way.
What went well? What didn’t go so well? What would you do differently next time?
