By the end of this lesson, Ss will understand:
- How to make suggestion and give response about saving energy
- How useful solar energy has
II/- Language contents:
1/- Grammar:
Some expressions of suggestion and response
2/- Vocabulary:
a) Speak: overflow, lid, gas cooker, cooking pot.
b) Listen: solar, nuclear energy, solar panel, install, store, effective
III/- Techniques: Group work, Brainstorm, Dicussion.
IV/- Teaching aids: Pictures.
V/- Procedure:
I Warm up (6 mins.)
- T gives the activities and the structures (the
verb form isn’t given.)

Suggestion:
I suggest + V-ing

- T corrects
1 Pre- speak:
óNew words:
- overflow (v): tràn
- lid (n): nấp vun
- cooking pot (n): nồi
- gas cooker (n): bếp ga
2 While- speak:
a)
A/ I suggest turning off the faucet

Trang 2- T supplies the response.
- T asks Ss to work in group and work out an
action plan to save energy for our class Section
a) may help Ss (5 minutes)
- First, T asks Ss to read the example, then T
explains
- Ss work in group and discuss in 5 minutes
- Later T calls two groups present their actions
- The others comments
- T comments

fans at recess
B: That’s a good ideas.
C: How about turning off the lights before
leaving the class?
D: OK III Listen (16 mins.)
- T asks Ss tointroduce some kinds of energy
- T explains exercise a) and b) and supplies new
words
Most of our electricity now comes from
nuclear power
- Some solar panels are installed on the roof of a
house to receive the energy from the sun
- It is possible to store solar energy for a number
of days
- T asks Ss to explain a) again
- Ss guess True or False?
- Ss listen twice and check T or F
- Ss listen again and correct false sentences
1 Pre- listen:
- solar ['soulə] (n) : → solar energy = power energy
- nuclear energy (n) = nuclear power
- solar panel (n) :
- install [in'stɔ:l] (v) :
- store [stɔ:] (v) :
1 While- listen:
a)
Energy
Trang 3- T gives correction.
* Gap filling:
- T asks Ss to read part b) and fill in
- Then T plays the disk again
- Ss listen carefully
- T asks them to give the anwser
- T corrects
KEY: 1 T.
2 F Most of our electricity comes from the use of coal, gas, oil or nuclear power
3 F 1% of the solar energy that gets to the Earth can provide enough power for the world’s population
4 T
5 F They will be heated by solar energy
in 2015
b) KEY:
1 effective
2 pollution
3 countries
4 store
5 roof intead
IV Production (5 mins.)
- T gives idea, Ss make sentences:
Ex: turn off the radio if not necessary.
Ò I suggest turning off the radio if not
necessary
Ò Why don’t we turn off the radio if not
necessary?
- Then T calls Ss to give ideas and the other
make suggestions
Post- speaking and listening
1) collect the garbage
2) turn off the lights before leaving
3) Install contal panel on the roof of the house
4) … Tape transcript:
Are you looking for a cheap, clean, effective source of power that doesn’t cause pollution or waste natural resources? Look no further than solar energy from our sun At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power This power could be provided by the sun One percent of the solar energy that reaches the Earth is enough to provide power for the total population.
Many countries are already using solar energy Solar panels are placed on the roof of a house and the Sun’s energy is used to heat water The energy can be stored for a number of days, so on cloudy days you can use solar energy too.
Sweden has an advanced solar energy program There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the tear 2015.
