Activity 2: Task 1 Accrding t the prmpts, review the structure and functin f the predicative clause.

Science is simply ____ yu can d. And ding science makes yu a scientist! S, what d scientists d? Actually, what matters is nt nly _____ they bserve in the wrld arund them and what questins they ask, but als _____ they use evidence r data t answer the questins. They identify useful data and take new measurements. Sme f the key issues that scientists face are ____ calculatins they d and ____ they analyse their data t draw cnclusins abut the questins they ask. The final issue, which many believe t be the mst imprtant, is _____ they need t cmmunicate their results. This is ______ they want everyne t benefit frm their wrk! It seems _______ science is all arund us. Yu see, by ding science, scientists get a better understanding f the wrld arund them and share that understanding with the whle wrld.
Activity 3: Reflecting
◎ What new ideas did yu learn abut science and scientists frm this unit?◎ What new vcabulary and structures did yu learn in this unit? Hw well can yu use them? Did yu use any f them in yur language activities?◎ D yu think the "asking questins" strategy was useful in understanding the texts?◎ What prblems did yu r yur friends have with this unit? Hw did yu slve the prblems? What advice did yu give each ther?◎ Overall, I thught this unit was ○inspiring ○interesting ○s-s ○difficult.
目标二: T think utside the bx and create an unusual inventin.
Mst great scientists have the ability t see the wrld in ways that ther peple d nt, and t cme up with new ideas that ther peple have never thught f. In many cases, this has caused ther peple t think that they are crazy at first. Hwever, that thinking ability is imprtant t their creative prcess.In this prject, yu are ging t create an unusual inventin.
Activity 1: Discuss these questins in grups.
1. What is the purpse f each inventin?2. Why is the inventin unusual?3. Chse ne f the inventins, and brainstrm as many reasns as yu can t explain hw and why the inventin is useful.
Activity 2: Finish the tasks.
write dwn ideas fr the inventin serve as the presenter fr the prduct/inventin make prps and pictures fr the inventin
Task 1: Assign grup members t prepare the fllwing:
Task 2: Create yur prduct and present it t yur class.
EXAMPLEPresenter: Des yur gldfish suffer frm lw self-cnfidence? Is he afraid t g ut int deep water? D female gldfish refuse t return his calls? Then yu can buy him ur new Gldfish Shark-Fin!

I'm s prud f him!Presenter: Yu t can change the life f yur fish! Fr just 999 yuan! Hurry! Buy it tday!
Task 3: As a class, vte n the best prduct/inventin.
Presenter: D yu have truble getting t class n time? Feel tired f walking t wrk? D yu need sme mre zip in yur step? Then try ur new Rcket Rller Skates. Just strap n the rcket pack, put n yur AI self-driving rller skates, and yu're ff!Man: Since I bught the Rcket Rller Skates. I am never late fr anything. And the AI self-driving system is a dream! I can even take a nap while zipping thrugh traffic. It's such a dream!Presenter: Yu dn't ever have t be late again! Fr just 999 yuan! Hurry! Buy it tday befre supplies run ut!

Emily Ainswrth: "It's part f human nature t _________ and t ________________ abut the wrld."2 Juan Martinez: "It's where yu find _______, where yu find new things, ______________.”3 Lee Berger: "We think we knw ________, but we dn't.

Task 3 Match the descriptins n the left with the wrds n the right.
Activity 3: After yu watch Discuss these questins in grups.
1 Of the explratins in the vide, which seems the mst imprtant? Which seems the mst interesting? Why?2 Why is it imprtant t explre, in yur pinin?3 Hw wuld yu like t explre ur wrld? Why?
Suggested answers:1 The mst imprtant is the ne with the butterflies, because butterflies are easily affected by climate and pllutin, and s their lives can tell us a lt abut hw the wrld is ding. The mst interesting is the cave diving where they fund the animal bnes. It just seems s strange and mysterius, and ne wuld nt expect t find bnes there.2 I think it is imprtant t explre because explratin is a part f human grwth, bth as an individual and sciety. Thrugh explratin, we develp urselves. Our interests and curisity cause us t learn, t imprve, and t be better.3 I wuld like t visit places with my camera and take phts f interesting places and peple, as I enjy phtgraphy and lve travelling and finding ut abut new cultures.
