写实验报告时，注意要完整介绍实验过程，用恰当的表示顺序的词语来清楚表述实验步骤。句式要多用祈使句，时态多为一般现在时。
实验报告通常包括以下内容：
1.实验目的：表明为什么要做这个实验。
2.实验用品：交代做实验要用的物品。
3.实验方法和过程：清楚、具体地写明实验步骤。在组织文字时，要正确运用表示顺序的词。
4.实验结果：如实且正确地记录实验现象或数据。
5.结论：通过实验得出相关的结论。
如何写实验报告
实验报告中常用的词语：
1.实验目的：aim, purpose, in order to, to find out...
2.实验用品：apparatus（仪器），beaker（烧杯），equipment, test tube（试管），test tube holder（试管夹），balance（天平），liquid, solid, gas...
3.实验过程：process, firstly, secondly, lastly, heat, boil, fill, add... to..., measure, weigh...
4.实验结果：result, conclusion, in a word, in conclusion...
练习
实验目的 测量镁在空气中加热后重量是否有变化
实验用品 镁（magnesium），本生灯（Bunsen burner），天平（balance），坩埚（crucible）
实验步骤 1.把镁放进坩埚内；
2.把坩埚放在天平上称重；
3.点燃本生灯，加热坩埚；
4.再把坩埚放在天平上称重；
5.比较两次称重的结果。
实验结果 第二次称重数据大于第一次称重数据
实验结论 镁在空气中加热后重量有变化
请根据下面表格中的内容写一篇100词左右的实验报告。
One possible version:
The aim of the experiment is to find out if there's a change in weight after magnesium is heated in air.
To carry out the experiment, you need the following things: magnesium, a Bunsen burner, a balance and a crucible. When all these are ready, you can begin the experiment.
First, put the magnesium in the crucible. Then put the crucible on the balance and weigh them. Next, light the Bunsen burner and place the crucible over it to heat the magnesium. Finally, weigh them again, and compare the two weights.
You can see the magnesium weighs a little more than before. That's because there is a change in weight after magnesium is heated in air.
