A class repeated a plant-growth experiment because the first result came from only three samples.
/ə klæs ɹɪˈpitɪd ə plænt ɡɹoʊθ ɪkˈspɛɹɪmənt bɪˈkʌz ðə fɚst ɹɪˈzʌlt keɪm fɹʌm ˈoʊnli θɹi ˈsæmpəlz./
At first, this looked like a small decision about science, but its result soon became visible.
/æt fɚst, ðɪs lʊkt laɪk ə smɔl dɪˈsɪʒən əˈbaʊt ˈsaɪəns, bʌt ɪts ɹɪˈzʌlt sun bɪˈkeɪm ˈvɪzɪbəl./
The case raises a broader question: how evidence and testing improve explanations.
/ðə keɪs ˈɹeɪzɪz ə ˈbɹɔdɚ ˈkwɛst͡ʃən: haʊ ˈɛvədəns ænd ˈtɛstɪŋ ɪmˈpɹuv ˌɛkspləˈneɪʃənz./
Because several factors influence science, the evidence supports a cautious conclusion rather than an absolute claim.
/bɪˈkʌz ˈsɛvɚəl ˈfæktɚz ˈɪnfluəns ˈsaɪəns, ðə ˈɛvədəns səˈpɔɹts ə ˈkɔʃəs kəŋˈkluʒən ˈɹæðɚ ðən ən ˈæbsəˌlut kleɪm./
The example draws attention to a conduct an experiment, which can shape how people respond to science.
/ðə ɪɡˈzæmpəl dɹɔz əˈtɛnʃən tə ə ˈkɑndʌkt ən ɪkˈspɛɹɪmənt, wɪt͡ʃ kən ʃeɪp haʊ ˈpipəl ɹɪˈspɑnd tə ˈsaɪəns./
People can test a hypothesis when a real situation involving science requires action.
/ˈpipəl kən tɛst ə haɪˈpɑθəsəs wɛn ə ɹil ˌsɪt͡ʃuˈeɪʃən ɪnˈvɑlvɪŋ ˈsaɪəns ɹiˈkwaɪɚz ˈækʃən./
Communities can develop a practical response to science by testing a small change first.
/kəˈmjunɪtiz kən dɪˈvɛləp ə ˈpɹæktɪkəl ɹɪˈspɑns tə ˈsaɪəns baɪ ˈtɛstɪŋ ə smɔl t͡ʃeɪnd͡ʒ fɚst./
The effect of science may vary according to a person's needs, resources, and circumstances.
/ðə ɪˈfɛkt əv ˈsaɪəns meɪ ˈvɛɹi əˈkɔɹdɪŋ tə ə ˈpɚsənz nidz, ˈɹisɔɹsɪz, ænd ˈsɚkəmˌstænsɪz./
An opinion about science becomes useful only after it is supported by a reason and an example.
/ən əˈpɪnjən əˈbaʊt ˈsaɪəns bɪˈkʌmz ˈjusfəl ˈoʊnli ˈæftɚ ɪt ɪz səˈpɔɹtɪd baɪ ə ˈɹizən ænd ən ɪɡˈzæmpəl./
However, an early success can hide a cost that appears later.
/ˌhaʊˈɛvɚ, ən ˈɚli səkˈsɛs kən haɪd ə kɔst ðæt əˈpɪɹz ˈleɪtɚ./
This matters because the decision changes what people can do in ordinary life.
/ðɪs ˈmætɚz bɪˈkʌz ðə dɪˈsɪʒən ˈt͡ʃeɪnd͡ʒɪz wʌt ˈpipəl kən du ɪn ˈɔɹdɪˌnɛɹi laɪf./
The immediate effect of science may be easy to see, while the longer-term effect is often less obvious.
/ðə ɪˈmidiɪt ɪˈfɛkt əv ˈsaɪəns meɪ bi ˈizi tə si, waɪl ðə ˈlɔŋɡɚ tɚm ɪˈfɛkt ɪz ˈɔftən lɛs ˈɑbviəs./
A careful comparison uses the same standard for both choices and separates convenience from lasting value.
/ə ˈkɛɹfəl kəmˈpɛɹəsən ˈjuzɪz ðə seɪm ˈstændɚd fɚ boʊθ ˈt͡ʃɔɪsɪz ænd ˈsɛpɚˌeɪts kənˈvinjəns fɹʌm ˈlæstɪŋ ˈvælju./
Once the difference is clear, a speaker can give a preference without pretending that the other option has no merit.
/wʌns ðə ˈdɪfɹəns ɪz klɪɹ, ə ˈspikɚ kən ɡɪv ə ˈpɹɛfɚəns wɪˈðaʊt pɹiˈtɛndɪŋ ðæt ðə ˈʌðɚ ˈɑpʃən hæz noʊ ˈmɛɹɪt./
Although one response may help, no single solution will suit every person.
/ɔlˈðoʊ wʌn ɹɪˈspɑns meɪ hɛlp, noʊ ˈsɪŋɡəl səˈluʃən wɪl sut ˈɛvɹi ˈpɚsən./
A balanced discussion of science should include an example, a limitation, and a conclusion.
/ə ˈbælənst dɪˈskʌʃən əv ˈsaɪəns ʃʊd ɪŋˈklud ən ɪɡˈzæmpəl, ə ˌlɪmɪˈteɪʃən, ænd ə kəŋˈkluʒən./
An important effect can change how people understand and respond to science.
/ən ɪmˈpɔɹtənt ɪˈfɛkt kən t͡ʃeɪnd͡ʒ haʊ ˈpipəl ˌʌndɚˈstænd ænd ɹɪˈspɑnd tə ˈsaɪəns./
When discussing science, people should explain why a possible solution matters.
/wɛn dɪˈskʌsɪŋ ˈsaɪəns, ˈpipəl ʃʊd ɪkˈspleɪn waɪ ə ˈpɑsəbəl səˈluʃən ˈmætɚz./
A balanced approach to science compares benefits, costs, and the needs of different groups.
/ə ˈbælənst əˈpɹoʊt͡ʃ tə ˈsaɪəns kəmˈpɛɹz ˈbɛnəfɪts, kɔsts, ænd ðə nidz əv ˈdɪfɹənt ɡɹups./
The main benefit of a thoughtful response to science is a result that people can actually observe.
/ðə meɪn ˈbɛnəfɪt əv ə ˈθɔtfəl ɹɪˈspɑns tə ˈsaɪəns ɪz ə ɹɪˈzʌlt ðæt ˈpipəl kən ˈækt͡ʃəli əbˈzɚv./
The main challenge is to respond to science without creating a larger problem elsewhere.
/ðə meɪn ˈt͡ʃælɪnd͡ʒ ɪz tə ɹɪˈspɑnd tə ˈsaɪəns wɪˈðaʊt kɹiˈeɪtɪŋ ə ˈlɑɹd͡ʒɚ ˈpɹɑbləm ˈɛlˌswɛɹ./
The most practical lesson is that science should be judged through real effects rather than attractive slogans.
/ðə moʊst ˈpɹæktɪkəl ˈlɛsən ɪz ðæt ˈsaɪəns ʃʊd bi d͡ʒʌd͡ʒd θɹu ɹil ɪˈfɛkts ˈɹæðɚ ðən əˈtɹæktɪv ˈsloʊɡənz./
A useful explanation also distinguishes what one person can change from what requires support from a larger institution.
/ə ˈjusfəl ˌɛkspləˈneɪʃən ˈɔlsoʊ dɪˈstɪŋɡwɪʃɪz wʌt wʌn ˈpɚsən kən t͡ʃeɪnd͡ʒ fɹʌm wʌt ɹiˈkwaɪɚz səˈpɔɹt fɹʌm ə ˈlɑɹd͡ʒɚ ˌɪnstɪˈtuʃən./
Good decisions connect a clear purpose with evidence, human experience, and the willingness to revise a weak approach.
/ɡʊd dɪˈsɪʒənz kəˈnɛkt ə klɪɹ ˈpɚpəs wɪθ ˈɛvədəns, ˈhjumən ɪkˈspɪɹiəns, ænd ðə ˈwɪlɪŋnəs tə ɹɪˈvaɪz ə wik əˈpɹoʊt͡ʃ./
When those parts stay connected, the topic becomes easier to discuss in daily conversation and in an IELTS answer.
/wɛn ðoʊz pɑɹts steɪ kəˈnɛktɪd, ðə ˈtɑpɪk bɪˈkʌmz ˈiziɚ tə dɪˈskʌs ɪn ˈdeɪli ˌkɑnvɚˈseɪʃən ænd ɪn ən aɪ ɛl ti ɛs ˈænsɚ./
