Good morning, Hana. Welcome to the chemistry lab.
早安,Hana。欢迎来到化学实验室。
#2
Good morning, Professor. I am really excited to be here today.
教授早安。我今天真的很兴奋能来到这里。
#3
That is wonderful to hear. Have you ever worked in a lab before?
那听起来太棒了。你以前曾在实验室工作过吗?
#4
No, this is my first time. I have only seen experiments on YouTube.
不,这是我第一次。我只在 YouTube 上看过实验。
#5
Well, real experiments are quite different from videos. Safety comes first here.
嗯,真实的实验与视频大不相同。在这里,安全是首要考虑。
#6
Of course. What do I need to do before we start?
当然。在我们开始之前,我需要做什么?
#7
First, you must put on your safety goggles and lab coat.
首先,你必须戴上你的安全护目镜并穿上实验衣。
#8
I found them on the table. Should I also wear these gloves?
我在桌上找到了它们。我也应该戴上这些手套吗?
#9
Yes, gloves are required because some chemicals can burn your skin.
是的,必须戴手套,因为某些化学物质可能会灼伤你的皮肤。
#10
Now, let me explain today's experiment. We will test how temperature affects dissolving.
现在,让我解释今天的实验。我们将测试温度如何影响溶解。
#11
That sounds interesting! So what is our hypothesis?
那听起来很有趣!所以我们的假设是什么?
#12
Good question. Our hypothesis is that sugar dissolves faster in hot water.
好问题。我们的假设是糖在热水中溶解得更快。
#13
I actually read about that online. I think the result will support it.
我实际上在网上读过相关内容。我认为结果会支持它(假说)。
#14
We shall see. A good scientist always waits for the result before deciding.
我们拭目以待。一位好的科学家总是在做决定之前等待结果。
#15
Here is the equipment we need: two beakers, a thermometer, and sugar.
这是我们需要的设备:两个烧杯、一个温度计和糖。
#16
I see. One beaker has cold water and the other has hot water.
我明白了。一个烧杯装着冷水,另一个则装着热水。
#17
Exactly. Now add one spoon of sugar to each beaker at the same time.
没错。现在同时在每个烧杯中加入一匙糖。
#18
Done! The sugar in the hot water is dissolving much faster already.
完成了!热水里的糖已经溶解得快多了。
#19
Excellent observation. Please write down the time when each sample fully dissolves.
出色的观察。请写下每个样本完全溶解的时间。
#20
The hot water sample dissolved in two minutes. The cold one took eight minutes.
热水样本在两分钟内溶解了。冷的那杯花了八分钟。
#21
So what can you conclude from this result?
那么,你能从这个结果中得出什么结论呢?
#22
The result shows that our hypothesis was correct. Hot water dissolves sugar faster.
结果显示我们的假设是正确的。热水溶解糖的速度更快。
#23
Well done, Hana. You have completed your first real experiment successfully.
做得好,Hana。你已经成功完成了你的第一个真实实验。
#24
Thank you, Professor! I enjoyed this much more than watching videos online.
谢谢教授!我喜欢这次的实验,比在网上看视频有趣多了。
#25
I am glad to hear that. Next week, we will design your own experiment.
我很高兴听到你这么说。下周,我们将设计你自己的实验。
