Write it up. - Write a passage ( about 100 words) about solar energy, using the information in the two exercises above. Sample: Most of our electricity now comes from coal, gas, oil or nuclear power. The sun could provide this power so many countries are already using energy. Only one percent of the solar energy that gets to the Earth can provide enough power for the world’s population. Solar energy is a cheap, clean and effective source of power that doesn’t cause pollution or waste natural resources. There is an advanced solar program in Sweden. It’s said that by the year 2015 , all building in Sweden will be heated by solar energy and cars will use solar energy power, too. Students Students Students Nguyen Thi Thien Giang 7 Unit 7 – Saving Energy Consolidation Home work We hope that there’s such program in Vietnam. We can save natural resource such as coal, oil, gas . by using solar energy. And every household in Vietnam has hot water in Winter without paying money. 2. Correct. - Students exchange their writings and correct. * - Review the lesson. - Prepare the next lesson : Read Students Nguyen Thi Thien Giang 8 Unit 7 – Saving Energy February, 13th 2007 Unit seven : Saving Energy Period 46 Lesson 4 : Read (P60 - 61) I.

Pre - Questions (Using poster) 1. Do people in Western countries think electricity , gas and water are luxury. 2. Do they want to save electricity? What do they do to spend less on lighting? 1. Reading and checking. - Have students read the text and check their Answers. - Some students read the text. Answer: 1. No, they do not. They think electricity , gas and water are not luxury but necessities. 2. Yes, they do.

( b/P61) 1. Western consumers are interested in products that will not only work effectively but also save money. 2. They can use energy- saving bulbs instead of ordinary 100w bulbs to spend less on lighting . 3. She will pay US$2. Because these bulbs use a quarter of the electricity of standard bulbs. 4. The labeling scheme helps the consumers know how energy efficient the household appliances are. 5. Because when we save energy, we will save money and conserve the Earth’s resources. 1.
