活动三：分析与判断
Discussion
Ask students to work in groups of four and discuss the following questions.
·Of the explorations in the video，which seems the most important？Which seems the most interesting？Why？
·Why is it important to explore，in your opinion？
·How would you like to explore our world？Why？
Suggested answers:
·The most important is the one with the butterflies because butterflies are easily affected by climate and pollution, and so their lives can tell us a lot about how the world is doing.
The most interesting is the cave diving where they found the animal bones. It just seems so strange and mysterious, and one would not expect to find bones there
·I think it is important to explore because exploration is a part of human growth, both as an individual and society. Through exploration, we develop ourselves. Our interests and curiosity cause us to learn, to improve, and to be better
·I would like to visit places with my camera and take photos of interesting places and people, as I enjoy photography and love travelling and finding out about new cultures.
【设计意图】在观看视频后，让学生讨论自已对科学探索重要性的认识，以及表达自己探索世界的方式，有助于培养学生的多元思维和利用本课所学的词汇在新的语境中表达自己的观点，有利于促进知识的内化，加深对主题意义的理解。
