High School Physics Department: Paper-Rope Dragging Competition

December 7, 2023

At the beginning of December, the Physics Teaching Group of Grade 10 held a unique paper-rope dragging competition in the Zhentao Building Lecture Hall. This highly creative activity not only exercised the students' practical abilities, but also enabled them to understand and apply the mechanical knowledge they had gained in a deeper way.

During the competition, students in Grade 10 formed teams of 2-3 people. They used old newspapers to make a paper rope no less than 60cm long within a specified time limit, and then used the rope to drag heavy objects such as textbooks. The competition was determined by the number and distance of the textbooks dragged.

Faced with a pile of newspapers, the students were enthusiastic and treated them as if they were precious treasures. They gave full play to their creativity and imagination, and turned the newspapers in their hands into "treasures from waste"! Some groups directly rolled the newspapers into a rope, while others flattened them into a hard piece of paper. Some groups also made the newspapers into many small strands of rope, which were then woven together to form a thick rope.

During the production and competition process, the students fully utilized the mechanical knowledge they had gained. They adjusted the stiffness and elasticity of the paper rope by changing the shape and structure of the newspaper in order to maximize the load-bearing capacity and drag distance of the paper rope. At the same time, the students also comprehensively evaluated the combined effects of friction, elasticity, pressure, etc., to ensure the optimization of the connection method between the paper rope and the heavy object.

The Physics Department head, Mr. Xu Zhencheng, and the head teacher of the 10th-grade physics group, Ms. Li Lejun, provided guidance and commentary throughout the competition. They praised the creativity and hard work of the students and emphasized the importance of using physics knowledge. At the end of the competition, some groups seemed to still be reluctant to stop. In order to fully demonstrate the power of paper ropes, the teachers present were invited by the students to act as heavy objects to be dragged. The students carefully increased the pulling force, and everyone on the scene held their breath. When a thin paper rope gradually overcame the maximum static friction and successfully slid, there was a thunderous applause and cheering all around!

The exciting and successful physics project competition integrated learning and teaching with fun and hands-on practice. It not only enriched the students' overall learning experience at school, but also further stimulated their interest and love for the subject of physics.
