Ropes and their uses for the sailor are the focus of this unit. Students begin the study by taking apart a section of rope and putting it back together, testing strength at various stages. They also practice tying different knots and learn about the uses of ropes in sailing. After investigating the mechanics of a block and tackle, students consider how ropes, ships and sailors have influenced the English language. Provided along with the students' guide is a teacher's manual which contains a materials list, objectives, recommended teaching approaches, an answer key, and evaluation items. (Author/WB)
