#1

Good morning, Hana. Welcome to the chemistry lab.

#2

Good morning, Professor. I am really excited to be here today.

#3

That is wonderful to hear. Have you ever worked in a lab before?

#4

No, this is my first time. I have only seen experiments on YouTube.

#5

Well, real experiments are quite different from videos. Safety comes first here.

#6

Of course. What do I need to do before we start?

#7

First, you must put on your safety goggles and lab coat.

#8

I found them on the table. Should I also wear these gloves?

#9

Yes, gloves are required because some chemicals can burn your skin.

#10

Now, let me explain today's experiment. We will test how temperature affects dissolving.

#11

That sounds interesting! So what is our hypothesis?

#12

Good question. Our hypothesis is that sugar dissolves faster in hot water.

#13

I actually read about that online. I think the result will support it.

#14

We shall see. A good scientist always waits for the result before deciding.

#15

Here is the equipment we need: two beakers, a thermometer, and sugar.

#16

I see. One beaker has cold water and the other has hot water.

#17

Exactly. Now add one spoon of sugar to each beaker at the same time.

#18

Done! The sugar in the hot water is dissolving much faster already.

#19

Excellent observation. Please write down the time when each sample fully dissolves.

#20

The hot water sample dissolved in two minutes. The cold one took eight minutes.

#21

So what can you conclude from this result?

#22

The result shows that our hypothesis was correct. Hot water dissolves sugar faster.

#23

Well done, Hana. You have completed your first real experiment successfully.

#24

Thank you, Professor! I enjoyed this much more than watching videos online.

#25

I am glad to hear that. Next week, we will design your own experiment.
