教材的地位、作用
本节内容是在学生初步了解压力及固体压强 之后进一步用实验探究的方法来研究液体的压 强。既是压强知识的延伸扩展，又是学习大气 压强和浮力知识的基础与铺垫，所以本节是联 系前后知识的桥梁，起着承上启下的作用。
因为液体受重力，所以液体对容器底部有压强。
演示实验
在上端开口、侧面蒙有 橡皮膜的玻璃瓶中缓缓 加水，观察橡皮膜形状 的变化。说明了什么？
因为液体具有流动性，所以液体对阻碍它散开的 容器侧壁有压强。
演示实验
将三面蒙有橡皮膜的玻璃管 缓缓的放入盛有水的量筒中， 观察橡皮膜形状的变化.说 明了什么？
橡皮膜向内凹陷，说明液体内部向各个方向都有 压强。

想想议议
实验猜想
液体内部的压强大小与什么因素有关？
液体的深度 液体的质量 液体的密度
液体的体积 所处方向 受力面积
理论推导
水柱的体积为 V= S h 水的密度为ρ 水柱的质量为 m= ρ V 水柱对底面积的压力为 F=G=mg = ρ V g = ρ S h g 水柱对其底面积的压强为 p=F/S=ρ S h g/S =ρ g h 根据上述推导从而确定，液体内部的压强 只与液体的密度与深度有关。
☆ Before listening. Ask students to look at the chart carefully. ☆ While listening. Students try to get the information and complete the chart .They must pay attention to the past forms of the verbs. Then check the answers together. ☆ After listening. Make a conversation with a partner. Talk about what Sally and Jim did last weekend.
1.通过观察、实验，培养学生的观察能力 和动手操作的能力。 2.通过对表格数据的分析，培养学生分析 实验结果，从中得出规律的能力.

教学反思
本节课主要用“实验--理论--理论与实验相结合”的 教学设计思路,让学生经历了“观察----猜想----探究----应用”的物理科学探究过程，注重了利用已有知识进行 理论推导，又用实验验证结论的可靠性。体现了从感性 认识到理性认识，从直观到抽象的 普遍认知规律。

学生情况分析
学生的前期知识
在学习本节课前，学生已经学过压力和压强等相 关知识，并学会利用实验的方法来研究问题。但学 生对实验方法和实验方案的选取和设计往往缺乏科 学性和严密性，因此要加强引导.
本校学生特点分析 由于本校属于农村校,学生各方面基础相对较薄 弱,虽然实验探究是本节的重要内容，但考虑到学生 的实际情况，适当的降低了实验的难度.在教学设计 上充分体现了因材施教的原则.
