Lesson 25 Let’s Do an Experiment一、语篇研读What：本课语篇是Danny、Jenny和Brian有关科学实验对话。
对话中，Brian和Jenny想对Danny做一个实验，在他头上放置一个装满水的广口瓶，用硬纸板盖住然后倒置，想看看会产生什么结果。
Danny认为水会撒到他的头上，于是穿上了雨衣，最后的结果是他并没有被弄湿。
所以得出结论大气压能帮助纸板让水留在瓶子里。
Why：Danny、Jenny和Brian有关科学实验的对话以及Danny的反映非常的有趣，既能让学生在轻松的氛围中学习英语、又能引起学生对科学的好奇心，继而用心学习和探索科学知识。
让学生能够运用相关知识和技能解释生活中的物理现象。
How：本课的语篇内容是Danny、Jenny和Brian三人的对话，主要内容关于科学实验的谈话。
通过两人对Danny的小实验，让人产生对科学的好奇。
对话可以分为两个部分：第一部分主要是对实验的猜想，用硬纸板盖住装满水的瓶子然后倒置会发生什么，Danny猜想水会撒到地上，Jenny猜想水会在瓶子里留着。
这部分包括了关于实验的主题词汇：experiment、jar、upside、pour、correct、scientific、method、raincoat等，以及表达状态的短语：fill...with...、 cover...with...、turn...upside down。
第二部分主要实验操作的过程以及最后得出的结论。
涉及到的重点词汇：pressure、conclude。
得出的结论“The air pressure helps the cardboard hold the water in the jar.”、“Air is stronger than I thought.”对话中使用了多种时态准确传达信息。
例如：使用一般将来时will do猜测实验产生的结果；使用现在完成时交流已经得出的结论。
