Flat surface to work on
challenge
Create a castle only using index cards, without scissors or tape. Folding, tearing or crumpling your cards is allowed!
Big Idea
If you carefully look at buildings in your neighborhood, nearest city, even ancient structures, you will notice that they are made of a series of shapes. The shape of a structure affects how strong it is. Rectangles, arches, and triangles are the most common shapes used to build big, strong structures.
Instructions
Work through as many of the tasks below to test out your ideas about the best shapes and methods needed to make an index card castle.
- Build a castle that is at least 3 stories high.
- Build a new castle, but this time use a different shape for your base than before. Try out triangles, squares, and circles. Which one works best?
- Use a timer to see how fast you can construct a tower. Invite someone to compete against you!
