Our Strong Structure

by Tony and John

We built two structures. Our first structure was a little box with pillars inside of the box. When Tony and I were putting the washers on, some fell inside the box and we threw it in the trash. We built a new structure and it was a cylinder. It held YunSang who weighs 126 pounds. It also held 34 dictionaries because we put some pillars in the cylinder.

We changed our structure to a cylinder because our first structure was weak!!!!!!! but our second structure was strong.

We put weight on the top of our structure.

I learned that index cards can hold any weight if the strong structure is strong. It holds a lot of dictionaries.
