1. 1

   A 선생님, 큰일 났어요. 과학 탐구 대회가 모레인데, 실험 결과가 가설이랑 완전히 반대로 나왔어요.

   Seonsaengnim, keunil nasseoyo. Gwahak tamgu daehoega moreinde, silheom gyeolgwaga gaseorirang wanjeonhi bandaero nawasseoyo.

   Sir, I'm in trouble. The science fair is the day after tomorrow, and my results came out the exact opposite of my hypothesis.

   Line 1
2. 2

   B 어떤 실험이었지? 주스 비타민 시 재는 거?

   Eotteon silheomieotji? Juseu bitamin si jaeneun geo?

   Which experiment was it? The one measuring vitamin C in juice?

   Line 2
3. 3

   A 네. 직접 짠 오렌지 주스가 파는 주스보다 비타민 시가 많을 거라고 가설을 세웠거든요. 근데 파는 주스 수치가 두 배 가까이 높게 나왔어요.

   Ne. Jikjeop jjan orenji juseuga paneun juseuboda bitamin siga maneul georago gaseoreul sewotgeodeunyo. Geunde paneun juseu suchiga du bae gakkai nopge nawasseoyo.

   Yes. My hypothesis was that fresh-squeezed orange juice would have more vitamin C than store-bought. But the store-bought juice came out nearly twice as high.

   Line 3
4. 4

   B 몇 번 했는데?

   Myeot beon haenneunde?

   How many times did you run it?

   Line 4
5. 5

   A 세 번이요. 세 번 다 똑같았어요. 다시 하고 싶어도 시간도 없는 데다가 시약도 다 떨어졌어요.

   Se beoniyo. Se beon da ttokgatasseoyo. Dasi hago sipeodo sigando eomneun dedaga siyakdo da tteoreojyeosseoyo.

   Three times. Same result every time. I'd like to redo it, but I'm out of time, and on top of that, I've run out of reagent.

   Line 5
6. 6

   B 세 번 다 같으면 오류일 가능성은 낮아. 그럼 그건 실패가 아니라 결과야.

   Se beon da gateumyeon oryuil ganeungseongeun naja. Geureom geugeon silpaega anira gyeolgwaya.

   If it was the same all three times, it's unlikely to be an error. Then that's not a failure, that's a result.

   Line 6
7. 7

   A 그래도 가설이 틀렸는데 그걸 어떻게 발표해요? 창피해요.

   Geuraedo gaseori teullyeonneunde geugeol eotteoke balpyohaeyo? Changpihaeyo.

   But my hypothesis was wrong. How can I present that? It's embarrassing.

   Line 7
8. 8

   B 과학은 틀린 가설에서 시작하는 경우가 생각보다 훨씬 많아. 중요한 건 왜 그렇게 나왔는지 설명해 내는 거야.

   Gwahageun teullin gaseoreseo sijakaneun gyeonguga saenggakboda hwolssin mana. Jungyohan geon wae geureoke nawanneunji seolmyeonghae naeneun geoya.

   Science starts from wrong hypotheses far more often than you'd think. What matters is being able to explain why you got that result.

   Line 8
9. 9

   A 왜 그런지 전혀 모르겠어요.

   Wae geureonji jeonhyeo moreugesseoyo.

   I have no idea why.

   Line 9
10. 10

    B 파는 주스 성분표 봤어?

    Paneun juseu seongbunpyo bwasseo?

    Did you look at the ingredients on the store-bought juice?

    Line 10
11. 11

    A 잠깐만요, 사진 찍어 둔 게 있어요. 음... '비타민 시 첨가'라고 쓰여 있어요.

    Jamkkanmanyo, sajin jjigeo dun ge isseoyo. Eum... 'bitamin si cheomga'rago sseuyeo isseoyo.

    Hold on, I took a photo. Um... it says 'vitamin C added.'

    Line 11
12. 12

    B 그렇지. 그게 결정적인 원인일 수 있어. 그리고 직접 짠 주스는 짜고 나서 얼마 있다가 실험했어?

    Geureochi. Geuge gyeoljeongjeogin woninil su isseo. Geurigo jikjeop jjan juseuneun jjago naseo eolma itdaga silheomhaesseo?

    There you go. That could be the key cause. And how long after squeezing the fresh juice did you test it?

    Line 12
13. 13

    A 아침에 짜서 오후에 했으니까 여섯 시간쯤이요. 뚜껑도 안 덮은 채로 뒀어요.

    Achime jjaseo ohue haesseunikka yeoseot siganjjeumiyo. Ttukkeongdo an deopeun chaero dwosseoyo.

    I squeezed it in the morning and tested it in the afternoon, so about six hours. I left it with the lid off, too.

    Line 13
14. 14

    B 비타민 시는 공기 중의 산소를 만나면 금방 줄어들어. 화학 시간에 배운 산화 기억나지? 그것도 원인일 수 있지.

    Bitamin sineun gonggi jungui sansoreul mannamyeon geumbang jureodeureo. Hwahak sigane baeun sanhwa gieongnaji? Geugeotdo woninil su itji.

    Vitamin C breaks down quickly when it meets the oxygen in the air. Remember oxidation from chemistry class? That could be a cause too.

    Line 14
15. 15

    A 와, 그럼 제 실험이 틀린 게 아니라 뭔가를 발견한 거네요?

    Wa, geureom je silheomi teullin ge anira mwongareul balgyeonhan geoneyo?

    Wow, so my experiment wasn't wrong. I actually discovered something?

    Line 15
16. 16

    B 바로 그거야. 발표 제목도 바꿔 보자. '직접 짠 주스가 더 건강할까? 예상 밖의 결과' 어때?

    Baro geugeoya. Balpyo jemokdo bakkwo boja. 'Jikjeop jjan juseuga deo geonganghalkka? Yesang bakkui gyeolgwa' eottae?

    Exactly. Let's change the title of your presentation too. How about 'Is Fresh Juice Healthier? An Unexpected Result'?

    Line 16
17. 17

    A 좋아요! 그럼 짜자마자 잰 결과랑 여섯 시간 뒤에 잰 결과를 비교하면 더 확실하겠네요.

    Joayo! Geureom jjajamaja jaen gyeolgwarang yeoseot sigan dwie jaen gyeolgwareul bigyohamyeon deo hwaksilhagenneyo.

    Great! Then if I compare a measurement right after squeezing with one six hours later, it'll be even clearer.

    Line 17
18. 18

    B 좋은 생각이야. 시약은 화학 준비실에 조금 남아 있을 거야. 내일 아침 일곱 시 반까지 와.

    Joeun saenggagiya. Siyageun hwahak junbisire jogeum nama isseul geoya. Naeil achim ilgop si bankkaji wa.

    Good thinking. There should be a little reagent left in the chemistry prep room. Be here by seven-thirty tomorrow morning.

    Line 18
19. 19

    A 일곱 시 반이요? 네, 갈게요. 모레까지 자료를 새로 만들어 낼게요.

    Ilgop si baniyo? Ne, galgeyo. Morekkaji jaryoreul saero mandeureo naelgeyo.

    Seven-thirty? Okay, I'll be here. I'll have new materials ready by the day after tomorrow.

    Line 19
20. 20

    B 좋아. 그리고 발표할 때 틀린 가설을 숨기지 마. 그게 네 발표에서 제일 과학다운 부분이야.

    Joa. Geurigo balpyohal ttae teullin gaseoreul sumgiji ma. Geuge ne balpyoeseo jeil gwahakdaun bubuniya.

    Good. And when you present, don't hide your wrong hypothesis. That's the most scientific part of your presentation.
