一、使用教材:自编教材二、实验器材:透明的水杯、可以弯曲的吸管、透明胶带、水、高锰酸钾、101胶水等三、实验创新点:通过五只杯子内存水量的对比,猜测被遮挡的第五只杯子的内部结构,激发学生动手动脑的兴趣,促进学生思维的发展。四、实验原理/实验方法设计思路:神奇水杯的设计利用了“虹吸现象”的原理。实验设计建立在学生呈现的前概念基础上展开。采用“图像法”把学生的抽象思维形象化,利用“类比法”激起学
First, the use of teaching materials: self-teaching materials Second, experimental equipment: transparent cups, can be bent straw, scotch tape, water, potassium permanganate, 101 glue Third, the experimental innovation: Through the five cup memory water contrast, Guessing the internal structure of the occluded fifth cup, to stimulate students interest in learning the brain, and promote the development of student thinking. Fourth, the experimental principle / experimental design ideas: the design of the magic cup to use “siphon phenomenon ” principle. The experimental design is based on the preconceptions presented by the students. Adopting the “Image Law” to visualize the students’ abstract thinking and using “Analogy” to provoke learning
