如何写实验报告 根据下面的提示,写一篇“观察水的沸腾”的实验报告(100 词左 右)。 实验目的: 1.观察水沸腾时的温度。 2.观察水沸腾过程中的现象。
实验器材 : 烧杯 (beaker) 、水、温度计 (thermometer) 、酒精灯 (ethanol light)、烧杯架、火柴。 实验步骤: 1.在烧杯里盛 100 ml 左右的水。 2.在水中放入温度计。 3.加热烧杯中的水,并观察温度计的示数和水的情况。 实验结果:当温度达到一百摄氏度时,水面出现大量气泡。 结论: 1.水在一百摄氏度时开始沸腾。 2.水在沸腾过程中有大量气泡产生。 写作提示:此题要求写一篇实验报告,要把实验目的、 器材、 步骤、 结果、结论交代清楚,语言简洁明了,忌拖泥带水。要采用实验报 告的格式。
(2)要将进行该实验的目的(aim)写出来。如 To find out if iron rusts in dry air / in air-free water / in ordinary water。 目的明确,才能写好实验报告。 (3) 把做实验所用的工具和材料 (material) 列出来。如 test tube,balance 等。 (4)按照实验步骤,一步步地写出实验方法(method)和过程,包括 使用的仪器、数据、收集程序、使用的任何药剂的剂量等,并写 出观察到的现象——这部分是实验报告的重点。如果记录不全面 或没有按实验步骤记录,就可能得不出实验结果。每个步骤可用 数字编号排列下来。在描述实验过程时,常会用到以下表示顺序 的词,如 first,then, next, after that, lastly 等。 (5)记录完步骤之后,写出观察到的实验结果(result)。 (6)根据实验,写出结论(conclusion)。
