Towards the end of last year, and as part of our upper-elementary school aged classes, I challenged each class to construct a tower using only paper straws and sellotape.
The reason for making the towers was that we were studying various famous towers around the world such as the Eiffel Tower, the Gerkin, the Oriental Pearl TV Tower, the Ostankino Tower and the Great Lighthouse of Alexandria as part of their textbook, Macmillan English. Unfortunately the children were not so impressed with these real world towers so get them more excited about the topic I let them build their own.
The results can be seen in the video below.
