In this activity, students will apply the concept of ratio and proportion to determine the length of the Statue of Liberty's torch bearing arm. By showing different sized pictures of the teacher participating in a marathon race, students are introduced to the term ratio. Students will view a video of the Statue of Liberty and are asked how long the arm would be if the nose measures 4 feet 6 inches. Given chart paper, string, and rulers, students develop their own strategy for finding the solution. They measure the length of their nose and the length of their arm and form a ratio. Using proportions, students will compute the length of the statues arm. Group results are displayed and compared. The actual length of the Statue of Liberty's arm is located in the almanac and compared to the lengths determined by the students.
