#1

Good morning, Hana. Welcome to the university's chemistry laboratory for your summer programme.

#2

Good morning, Professor James! I've been looking forward to this for weeks.

#3

I'm glad to hear that. Before we begin any experiment, we must discuss safety procedures.

#4

That makes sense. My school lab has strict rules too, but I imagine yours are even stricter.

#5

First, always wear your safety goggles and lab coat when handling chemicals or heated equipment.

#6

Got it. What about gloves? I've seen scientists wearing them in YouTube videos.

#7

Good observation. Gloves are required whenever you handle corrosive or toxic substances directly.

#8

Should I also tie my hair back? I read that loose hair can be a hazard near flames.

#9

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

#10

Oh, cool! So what's our hypothesis? That higher temperatures make reactions faster?

#11

Precisely. Our hypothesis states that increasing temperature will accelerate the rate of reaction.

#12

I learned about this in class, but I've never actually tested it with real equipment before.

#13

That's exactly why hands-on experience matters. Now, let me show you the equipment we'll be using.

#14

Is that a Bunsen burner? I've only ever used electric hot plates at school.

#15

Yes, it is. You'll also need beakers, a thermometer, a stopwatch, and the chemical solution.

#16

Should I measure the solution first, or should I set up the burner and wait for instructions?

#17

Excellent question. First, measure fifty millilitres of solution into each of the three beakers.

#18

Done! I've measured the solution into all three beakers. What temperature should each one be?

#19

Heat the first beaker to thirty degrees, the second to fifty, and the third to seventy.

#20

The reaction in the hottest beaker is happening so much faster! This is amazing to watch.

#21

Wonderful. Now record the result for each beaker, including the exact time each reaction took.

#22

So our hypothesis was confirmed by the results. Higher temperatures really do speed up reactions!

#23

Well done, Hana. Having completed your first proper experiment, you should feel quite proud of yourself.
