II. Checking homework.

Students had to make notes about all possible ways to save energy while doing their everyday routine and try the ways practically.

Students read their ideas about saving energy in everyday life and comment on whether they find it difficult to stick to them.

Tips on saving energy

Whenever you leave a room, don’t forget to turn 1) ___ the light. And that goes for TVs and computer too! Here’s a bright idea. Have your parents replace incandescent (standard) light bulbs with compact fluorescent light bulbs (CFLs). They use up to 75% less electricity and last up to 10 times longer than standard bulbs.

Before you turn 2) ____ a light in a room, stop and think. Do you really need it? Or is there enough natural daylight already?

Give the dryer a break. Convince your parents to use a clothesline instead of a dryer. You’ll help cut 3) ____ on the amount of electricity they use.

Dirty dishes and laundry can wait. You should only run a dishwasher or dryer when it’s full. And it’s best to turn it on later in the evening. That way, it’s not being used during peak electricity periods.

On sunny summer days, close the drapes and blinds to keep the sun’s warm rays 4) ______. It’s a natural way of keeping the house cool. In the winter, open drapes and blinds to let the sun’s warming rays 5) _____.

At night, close them to keep the heat in. Instead of turning 6) ____ the air conditioning on a warm day, use a fan to cool things 7) _____. It requires a lot less electricity than an air conditioner. Now that’s cool!

Looking 8) ____ a snack? Don’t just leave the fridge door open while you search high and low for something to eat. That’s a surefire way to waste electricity. Decide what you want to munch 9) _____ before you even open that fridge door.

When it’s time to grab a bite to eat, have your folks reheat food in a toaster or microwave oven. It’ll save more electricity than if they used the oven.

 Ghost bust those phantom loads! (Phantom load is electricity consumed

by electronic devices even when turned off.) Plug electronics like TVs, computers, game consoles, and chargers (MP3 players, cell phones, cameras etc.) into a power bar. With one easy flip of a switch you’ve got the power to bust those ghosts. Some even shut-off automatically.

Don’t get print-happy. To conserve electricity and paper, only print things when you really need to.

To save hot water, give 10) _____ on baths. (Don’t panic…we’re not saying to ditch cleanliness completely!) Take a quick shower instead. You’ll use about half as much hot water than if you took a bath.

Stop those drips! Have your parents fix any leaky faucets around the house. A constant drip can waste 182 litre-sized bottles of water a week!

 

1. a) on  b) off  c) up
2. a) in b) on c) down
3. a) down b) of c) from
4. a) out b) up c) apart
5. a)away b) in c) for
6. a) up b) back c) into
7. a) around b) up c) in
8. a) about b) for c) on
9. a) over b) around c) on
10. a) up b) out c) from

IV. Post-reading  discussion.

Ask students what tips were not mentioned by them in their homework notes.

Discuss what points they are going to try to cut their water and electricity expenses.

V. Game “Spot the slip-ups”

As students have gained knowledge on saving offer them to check it in an entertaining way.

http://kids.saveonenergy.ca/en/games/spot_the_slipups.html

Students take a look at the big scene and see if they can spot the ways they are wasting energy. To find the areas, they click the magnifying glass and drag it around the scene. To reveal the tip, they click the mouse button when an object is highlighted in red.

 

VI. Grammar practice

Tell your students that our homes and lives have become so dependent on electricity that it is really hard to imagine everything that would change without it. But a hundred years ago life was quite different. Offer to compare some things then and now.

Instruct students to fill in the blanks with appropriate active or passive verb forms. Some of them can be used several times.

keep, use, do, wash,  be, hang, can clean, turn

Then	Now
Clothes __________ by hand with soap and water.	Washing machines ________ clothes in less than an hour.
Clothes __________ outside on clothesline to dry.	Dryers _________ wet clothes to dry clothes quickly.
Boxes  with large blocks of ice ____________ to keep foods cold.	Refrigerators ________ food cool or frozen.
Charcoal and wood stoves ___________  for cooking and heating.	Electric and gas oven  ________ for cooking in most kitchens
Candlelight, oil lamps and kerosene lamps _______ to light homes.	Electric light bulbs, including energy-saving, ______ everywhere.
Household cleaning ____________ with a broom and dustpan.	Some of today’s vacuum cleaners _________ strong enough to pick up a bowling ball.

VII. Speaking

Discuss advantages and disadvantages of life without electricity.

Possible answers:

Advantages

Disadvantages

The environment is not polluted and natural resources are conserved.  People do not depend on machines and do not spend too much time watching television and surfing computer. People have to move more and be more active doing their household chores. People don’t spend money on electrical appliances such as air conditioners, washing machines, televisions and so on.

People do not have electricity for lighting which makes life much less comfortable. People have to spend more time on household chores and less on creative work or entertainment. People don’t use the Internet that makes life unbearable!!!!! No chatting, no likes on Instagram. It is very hard to do a lot of things that are taken for granted nowadays: to dry hair, to cool/heat air in the room, to store food, to take a warm shower and so on.

 

VIII. Hometask

Students write a short essay on the topic “Life With  And Without Electricity”

Remind them to follow the structure:

Introduction: Address the question, show why it's interesting and how you will answer it.

Main body: Build your argument. Put your groups of ideas in a sequence to make a persuasive argument. One main point in each paragraph.

Conclusion: Summarize your arguments and evidence, and show how they answer the original question.
