一、设计意图期中考试临近,压强的知识对于初中生来说是一个难点,因为其概念较为抽象,大部分学生学习时会感到困难,不会灵活应用压强的两个公式来解决实际问题。希望通过本节课的教学,帮助学生建立起压强的知识体系,认清固体压强和液体压强的不同之处,掌握解决问题的方法,教学中采用对比法和归纳法,师生讨论的方法等。

Hope that through this lesson teaching, to help students build a knowledge system of pressure, recognize the difference between solid pressure and liquid pressure, master the method of solving problems, teaching using contrast and induction, teachers and students to discuss the method .
