REFLECTING
*Project：Give a presentation on natural
disasters
BRAINSTORM：Work in groups of three or four. Choose one of the natural disasters below and brainstorm answers to the questions.
Understanding the disaster
Are there any known causes of the disaster
What can be done to prevent it
Earthquakes are caused by tectonic plates shifting.
Preparing for the disaster
What are the possible effects of the disaster
What can be done to prepare for it
Check your home for areas that may be weaker in an earthquake. Also look at your things；for example，furniture such as a wardrobe which is not attached to a wall may fall easily，and glass on a high shelf could be dangerous.
Also find the safest area too. Keep some supplies at home，such as food and water，a torch，radio and first-aid kit，as an earthquake can affect access to basic things. Always shave a plan，and practice for what you will do when there is an earthquake. Some knowledge of basic medical procedures may also be very useful.
In the event of a disaster
What can you do to stay safe during the disaster
What kind of help do survivors need
Don′t panic! Remember your plan and follow it calmly. Take cover in the safest area，perhaps under a strong door frame or table. Use your supplies and stay in contact with others so they know you are OK. Keep an eye on and help the vulnerable，such as old people，young children and pets.
RESEARCH：Which questions do you not
know the answers to Which ones do you
need more information on Use the internet
or your school library to find out more.
ORGANISE：Put together a presentation
using the information you have gathered.
Use the tips below to help you.
Start your presentation with a “hook” (a story or fact to catch the attention of your listeners).
On Monday，5 September 20XX，600 people
disappeared when ...
Reduce your ideas to three main points to help listeners remember what you say.
So always remember to drop，cover and hold on. ...
Prepare visual aids for your presentation (photos，charts，tables，etc.).
In 2016 in Alberta，Canada，a wildfire destroyed over
2，000 houses and became one of the most expensive natural disasters in Canada′s history. Wildfires are caused when forests are left to grow and get too dry. They can become dry when there is a drought or when there is not enough snow to keep them wet. Then a person who might be hiking or camping can start a fire or lightning can strike a tree which also causes a fire.
Because the forest is dry，other trees quickly catch fire. Wildfires can spread very quickly and many people，including firefighters，are caught by surprise when a fire races over a hill towards them. The best way to prevent a wildfire destroying your life is to pay close attention to the news and be ready to evacuate very quickly if authorities say it′s time. A house or car can be replaced，but lives are far more precious.
4 PRESENT：Give a group presentation to your
class.
* Video Time
Tsunami：Killer Wave
Tsunami waves can strike out of nowhere and cause a lot of destruction. Scientists study and track tsunamis in order to warm people and minimise deaths.
BEFORE YOU WATCH
Read the sentences about the formation and effects of tsunamis. Then match each sentence with the correct picture.
A Tectonic plates push together.
B A series of waves expands in all directions.
C Whole sections of cities are destroyed.

WHILE YOU WATCH
1 Decide whether the statements are true (T) or false (F).
1 There are few warning signs just before a tsunami hits.
2 A tsunami breaks just like an ordinary wave but is bigger.

3 Scientists at the Pacific Tsunami Warning Center monitor
the earth′s movements 24 hours a day in order to track
tsunamis.

2 Circle the correct word(s) in each sentence.
1 An earthquake occurs when plates below the earth′s
surface push together/pull apart.
2 Tsunami waves deep at sea move fast and rise only a
few/hundreds of feet.
3 As these killer waves enter shallow waters，their speed
is reduced/raised.
4 Most tsunami damage is caused when the waves come
in from/move back out to the sea.
AFTER YOU WATCH
Work in pairs. Discuss the questions.
1 What have you learnt about tsunamis
2 What kind of help do you think people who have suffered
from a tsunami need
1 What have you learnt about tsunamis
I have learnt that they are dangerous./...that they aren′t noticeable or strong until they hit the coast./...that they cause more damage when they recede.
2 What kind of help do you think people who have suffered
from a tsunami need
They need food，water，shelter，etc. They may also need medical help and emotional help if they have lost loved ones.
