Strength from Weakness
This is the paper you can use to fold the paper arch.
You can download this as a Word file, or I have copies.

Balsa Bridges:
Joints: When you create a balsa bridge, you will have a great deal of individual pieces that will need to be joined together. The type of joint you use when joining two pieces can make or break your bridge. There are a number of different types and they all have their pros and cons. Click the link above to investigate some joint types. When you create your plan for your bridge, you will need to label what type of joints you will be using.
Examples of Balsa Bridges
The slides to the left will guide you through the building process.
