《纲要》中指出“善于发现幼儿感兴趣的事物和偶发事件中所隐含的教育价值，把握教育的时机，提供适当的引导” 的要求，所以大班组的高老师设计了本次教学活动。
Open classes are a great opportunity for teachers to reflect and encourage teachers to explore new ways of teaching.
《纸绳力量大》通过设疑、实践，激发幼儿探索科学奥秘的兴趣，在反复实验、动手操作的游戏中，让孩子们发现卫生纸里存在“纤维”这一有趣的现象，在操作中尝试制作纸绳，探索纸绳有承重力的特点，通过实验寻找纤维的走向，积极合作，体验团结起来力量大，孩子们在探究游戏中感受快乐，获得智慧。
对于科学活动来说，适宜的操作材料是十分重要的，再次本次活动是结合他们本班生活实际问题开展的，孩子的积极性和探索的欲望都很强烈，所以在有操作材料跟兴趣的结合下，本次活动从制作纸绳到提起水桶，孩子们都很努力去挑战不能完成的任务。
In the game of trial and error, children can discover the interesting phenomenon of "fiber" in toilet paper. In the activity they try to make paper rope, exploring the characteristics of weight-bearing through experimentation. This was an opportunity for children to practice scientific exploration.
It is very important for scientific activities to have methods and materials that children can safely explore and experiment. The children were challenged to lift buckets with their toilet paper ropes. The children’s enthusiasm is strong when they can explore on their own and work together to complete a task through trial and error.
课后，全体教师进行了评课，大家各抒己见，总结公开课中的亮点和有待改善的地方，高老师自身也针对课堂教学设计、教学目标、教学过程进行了自我反思。
本次公开课活动，既展现了幼儿园老师们团结合作、相互促进、互相学习的精神，也更加促进教师们在教学中以幼儿为本、以游戏为主、创新意识的提高，全园上下形成互学互讲互评共同进步的良好局面。
After class, all teachers have carried out an evaluation. The teacher who taught the lesson also evaluated themselves. This is with the thought of planning, implementation, and reflection.
This open class activity shows the spirit of cooperation, mutual promotion and mutual learning between kindergarten teachers. Also promoting teaching of children-oriented and game-oriented activities.
