King Edward has asked you to design and build a mighty siege machine—called a trebuchet—that will fling a grape across a far distance. You have been provided with some materials to build your trebuchet: You must use plastic soda straws for all long construction pieces and a straightened paper clip for the axle. Your missile will be a grape. Study the diagram below before designing your grape-throwing trebuchet.
You will need to construct the following parts of a working trebuchet:
To connect the straws together, pinch the end of one straw and slide it into the end of another straw. Wrap a band of tape around the joint to secure the connection.
Consider these and other methods as you design and build your trebuchet. As you work, keep a journal describing your design successes and failures. Include detailed, labeled drawings and descriptions in your journal. Tell what you discovered as you worked.
