- Helping students to use the words related to the sources of energy through reading and writing

Vocabulary : fossil fuels, alternative, nuclear energy, geothermal heat/energy, solar power/panel, potential, to release, to create, exhausted, limited, plentiful, infinite

Teaching Aids: pictures of sources of energy; projector (if available); textbook

B.PROCEDURE:

T Contents T & Ss’activities

I) WARM UP: (5 MINUTES)

Al the pictures should show different

kinds of producing energy, such as

wind power, solar energy,

hydroelectric plant, etc

 Write the words of different

Textbook page 124, or provides some mores pictures on cardboard or by projector

 Students look at the pictures on the board

 Check the results and correct them if necessa(or in their books) and try to distainguish the sources of energy

II) PRE-READING: (10 minutes)

- What do we need energy for?

- What kind of energy is the most

popular in Vietnam?

1.Vocabulary:

fossil fuels(n) : nhien liêụ hoá thạch

alternative (a): thay th ê

nuclear energy (n) : n ăng l ư ơng

nguy ên t ư

geothermal heat/energy(n) : h ơi nong

đ ịa nhi êt

solar power/panel(n): Tam thu năng l

ư ơng m ăt trơì

potential (n) Tiem n ăng

to release (v) th ải ra

to create(v) : t ạo ra

 Exchange with their partners and match the words given with the right pictures

power produced by hydroelectric

plants

III) WHILE READING: (25

MINUTES)

1.Task 1:The words in the box

all appear in the passage Fill in the

work in groups before giving their answers:  Students get to understand these words:

fossil fuels; alternative; solar panel; dam; nuclear; available; potential; limited; unlimited

 Students copy the words

in their notebooks after the teacher's corection on the board

 Students work in groups discussing the teacher's questions

 Teacher has students

blank with a suitable word( Use

dictionary when necessary)

Suggested answers:

1 released 2 alternative 3 energy

4 limited 5 exhausted

2.Task 2: Scan the passage and write

down the advatages and disadvantages

of each altenative source of energy

Suggested answers:

Sources Advantages Disadvant

listen to the recording of the passage two times, then read

it in silence (Teacher should go round to check and give help where necessary.)
