Context: Buildings and other structures are constructed in many shapes and sizes. Columns used in construction are also in many different shapes and sizes. The CN Tower, too has a distinct shape. The shape and size of these structures allow them to reach great heights.

Possible Solutions: circles, triangles, squares, other polygons, slender, wide

Design Constraints: The following are some constraints or limitations for this project:

1. You may work in groups of two
2. The project will be evaluated this period
3. The tower can not be taped to the floor or any supports
4. You have 45 minutes to complete the project
5. You will have three sheets of paper and 2” of tape.

Detail Design: The following are the steps to designing and making your tower:

1. Ensure that the work area is clear of hazardous materials (i.e., oil, gas, rags, wood, plastic, etc.)
2. Plan ahead what you are planning to do. Discuss this with your partner
3. Construct your tower in rough using the white paper.
4. Build your final tower using the coloured paper.
5. Clean-up your work area and put your tools away.

Materials: sheet of paper, tape, rulers, and scissors.
