如何写英文实验报告
今天在化学课上做了一个实验，请按照以下提示写一篇词数100左右的英文实验报告。内容如下：
实验目的：检验铝在空气中加热后，重量是否会发生变化。
实验器材：铝片、酒精灯、天平、坩埚、坩埚钳。
实验步骤：
第一步：把铝片放在坩埚里，然后放在天平上称重。
第二步：点燃酒精灯，将盛有铝片的坩埚移到酒精灯上加热三分钟。
第三步：再称坩埚和铝片的重量。
实验结果：比加热前略重一些。
实验结论：铝在空气中加热后，重量会发生变化。
1. 审题与定调
实验报告属于说明文体裁，其最大特点就是知识性、严谨性和科学性。它是对客观事实的阐述，措辞要严谨真实，准确恰当。
实验报告需要客观地介绍实验的整个过程。可以按照实验目的——实验器材——实验步骤——实验结果的顺序依次进行说明。介绍操作过程可适当使用表示顺序的词汇，使叙述条理，清楚明了。
2. 确定主体内容
实验报告主要围绕实验过程及结果，即铝片加热以后看其重量是否发生变化。
3. 审定篇章结构
全文可分三个自然段：
第一段：说明实验目的和所需实验器材。
第二段：实验方法或实验的过程及结果。
第三段：实验得出的结论。
常用表达

范文
We carried out an experiment today to find out if there was a change in weight when aluminum was heated and following apparatus was used: pieces of aluminum, an alcohol burner, a balance, a crucible, and a pair of crucible tongs.
Firstly, we put the pieces of aluminum in the crucible and we put the crucible on the balance and weighed it. Secondly, we lit the alcohol burner, held the crucible with the aluminum in it over the burner, and then heated the aluminum for three minutes.
Finally, we put the crucible with the aluminum in it on the balance and weighed it again and it weighed a little more than before.
So we came to the conclusion that there was a change in weight when aluminum was heated.
