what’s out there.”

Step II 应用实践
Discuss the following questions in groups.
Of the explorations in the video, which seems the most important
Which seems the most interesting Why
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.
Discuss the following questions in groups.
Why is it important to explore, in your opinion
How would you like to explore our world Why
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.
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.
Complete the passage with the correct forms of the words. (Assessing Your Progress)
brilliant solid microscope finding contradictory gift astronomer theory
The scientist’s main task is to discover how things work in the universe. But few scientists have placed themselves under the ____________. So even though the ____________ scientific method, which mainly includes hypotheses, data collection, and statistical analysis, is written down, the method by which scientists come to ____________ conclusions is hard to identify. Two of the essential qualities a scientist needs to have seem to be curiosity and creativity. People who are curious usually have a mixture of seemingly ____________ desires: They are looking for originality and yet they also want everything in its proper place. To settle the conflict between statistics and ____________, scientists often have to be creative, and think outside the box—approach the problem from different directions. They must have a vivid imagination and a strong intuition in order for new ____________ to be made. It echoes something the ____________ Carl Sagan once said. He believes that every child “starts out as a scientist” and every child is ____________ with the “sense of wonder and awe”.

Fill in each blank with a word or expression that introduces a predicative clause. (Assessing Your Progress)
Science is simply ________ you can do. And doing science makes you a scientist! So, what do scientists do Actually, what matters is not only ________ they observe in the world around them and what questions they ask, but also ________ they use evidence or data to answer the questions. They identify useful data and take new measurements. Some of the key issues that scientists face are ________ calculations they do and ________ they analyse their data to draw conclusions about the questions they ask. The final issue, which many believe to be the most important, is ________ they need to communicate their results. This is ________ they want everyone to benefit from their work! It seems _________ science is all around us. You see, by doing science, scientists get a better understanding of the world around them and share that understanding with the whole world.
