today is monday; i wake up at 6 o’clock in the morning. then i have my breakfast at home and take the subway to school. i am quite excited about this day, because our chemistry teacher will teach us to do an interesting experiment. this experiment is about how to create soap. last week, the chemistry teacher promised that we would have something fun in this week. making our own special soap is the mission in this class.
when the experience begins, the whole class is very exciting; we mix the oil, water and lye. you need to be very careful, because the lye is harmful to the skin. then we will stir the oil and lye for about ten minutes, the chemistry reaction will make the liquid into solid. then the soap comes into being. although the process is tired, we have a lot of fun. the most important thing is we learn how to make soap. the time passes so quickly, we feel very busy but learn a lot of useful things.
今天是星期一，我早上六点就起床了。再吃过了早餐之后，我搭地铁去学校。对于今天要做的事情，我很兴奋。因为我们的化学老师要教我们做个有趣的实验。这个实验就是如何制作肥皂。上个星期，化学老师向我们保证这周会做个有趣的实验，而创造出属于自己的一块肥皂就是这次课的主要内容。
当实验开始的时候，整个班级都很兴奋。我们把油、水和碱液混合在一起。你必须非常小心，因为碱液会腐蚀皮肤。然后我们就开始搅拌液体。大约10分钟过后，发生的化学反应就把液体变成了固体，肥皂就形成了。虽然这个过程很累，但是我们得到了很多乐趣。最重要的是我们学会了如何制作肥皂。时间过得太快，我们感觉很忙碌，但也学到了很多有用的东西。
