Task 2 Complete the passage with the correct forms of the words below.
The scientist's main task is to discover how things work in the universe. But few scientists have placed themselves under the __________.

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.

Task 2 Fill in each blank with a word or expression that introduces
a predicative clause.
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.

Activity 3: Reflecting
◎ What new ideas did you learn about science and scientists from this unit
◎ What new vocabulary and structures did you learn in this unit How well
can you use them Did you use any of them in your language activities
◎ Do you think the "asking questions" strategy was useful in understanding
the texts
◎ What problems did you or your friends have with this unit How did you
solve the problems What advice did you give each other
◎ Overall, I thought this unit was ○inspiring ○interesting
○so-so ○difficult.
目标二: To think outside the box and create an unusual invention.
Most great scientists have the ability to see the world in ways that other people do not, and to come up with new ideas that other people have never thought of. In many cases, this has caused other people to think that they are crazy at first. However, that thinking ability is important to their creative process.
In this project, you are going to create an unusual invention.
Activity 1: Discuss these questions in groups.
1. What is the purpose of each invention
2. Why is the invention unusual
3. Choose one of the inventions, and
brainstorm as many reasons as you
can to explain how and why the
invention is useful.
Activity 2: Finish the tasks.
write down ideas for the invention
serve as the presenter for the product/invention
make props and pictures for the invention
Task 1: Assign group members to prepare the following:
Task 2: Create your product and present it to your class.
EXAMPLE
Presenter: Does your goldfish suffer from low self-confidence Is he afraid to go out into deep water Do female goldfish refuse to return his calls Then you can buy him our new Goldfish Shark-Fin! For just 999 yuan, you can turn your goldfish into a real go-getter!
Woman: Since I bought the Goldfish Shark-Fin for my Henry, he has turned into a new fish! Now he swims with the big fish! I'm so proud of him!
Presenter: You too can change the life of your fish! For just 999 yuan! Hurry! Buy it today!
Task 3: As a class, vote on the best product/invention.
Presenter: Do you have trouble getting to class on time Feel tired of walking to work Do you need some more zip in your step Then try our new Rocket Roller Skates. Just strap on the rocket pack, put on your AI self-driving roller skates, and you're off!
Man: Since I bought the Rocket Roller Skates. I am never late for anything. And the AI self-driving system is a dream! I can even take a nap while zipping through traffic. It's such a dream!
Presenter: You don't ever have to be late again! For just 999 yuan! Hurry! Buy it today before supplies run out!
Suggested Answer (text only):
目标三: To understand the importance of scientific explore by watching the video.
Activity 1: Before you watch
What do you think you will see in the video Tick the items that you think will be mentioned.
□ airplane □ butterfly □city □ computer
□ diver □fog □ horse □ polar bear
□ship □ submarine □ volcano □whale
Activity 2: While you watch
Task 1 Check your answers from Before You Watch.
□ airplane □ butterfly □city □ computer
□ diver □fog □ horse □ polar bear
□ship □ submarine □ volcano □whale
1. Emily Ainsworth: "It's part of human nature to _________ and to
________________ about the world."
2 Juan Martinez: "It's where you find _______, where you find new things,
______________.”
3 Lee Berger: "We think we know ________, but we don't. We think we
know________, but we don't. We think we understand ______________,
but we don't."
4 Catherine Workman:“___________ what's out there, ____________
what's out there.
5 Cory Richards: "And if we have more to care about, then we engage
more fully _____________ and more fully ___________________, and
we act-you know-________.”
Task 2 Complete these quotes with the words you hear in the video.
be curious
want to learn more
yourself
where you grow
this place
ourselves
how things work
By knowing
we care about
with our world
with our human family
with love
1 a first flight A fish
2 used to explore an inaccessible place B frog
3 a new species C polar bear
4 eight new species D butterfly with a tag
5 a natural alarm clock E drone
Task 3 Match the descriptions on the left with the words on the right.
D

C
Activity 3: After you watch Discuss these questions in groups.
1 Of the explorations in the video, which seems the most important
Which seems the most interesting Why
2 Why is it important to explore, in your opinion
3 How would you like to explore our world Why
Suggested answers:
1 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.
2 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.
3 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.
1. Recall some key words and phrases in this unit.
2. Show your unusual invention to your classmates.
3. Why is it important to explore
