Warm up
Warm-Up:
Air Pollution in Your Town
1. Write
the words “Air Quality” on the board and ask students the following questions:
a) Do you
think the quality of the air in this area is good or bad?
b) How do
you know? What evidence is there of air pollution? Answers might include
smog, a high occurrence of asthma or other respiratory diseases, a bad smell,
or particulates settling out of the air. Or they may infer there is poor air
quality without evidence because of the presence of industrial practices
nearby. Alternatively, they may believe air quality is good because of the
absence of all these things.
c) Have
you ever experienced burning eyes, itchy throat, or shortness of breath on
polluted days?
d) What
time of the year does the air seem dirtiest? Kids may not notice, but air
pollution is typically worse in the summer months because of higher
temperatures and more sun which both help create certain pollutants like ozone.
Also, there is less rain to wash pollutants out of the air and away.
2. Ask students why there is so
much talk about air quality? Guide them to identify the importance of air
for living things. Explain that bad air can contribute to a variety of
illnesses such as asthma and cancer. Air pollution can also decrease the
efficiency with which plants photosynthesize, making them less productive.

give you text and we will read and translate
Air pollution is actually the addition of any harmful
substances to the atmosphere, which causes the damaging of the
environment, human health and the quality of life. With the development in
industry, came along the increase in air pollution, which occurs
inside homes, schools, offices even in the countryside. Consequently
there has been an increase in the death rates resulting from various
diseases caused by air pollution varying from breathing problem to lung
cancer. Air pollution does not only affect people but it also damages
the whole ecological system in which plants and animals are harmed as well. Air
pollution has reached such a critical stage where it affects the earth's
atmosphere as it lets in more harmful radiation from the sun. Polluted
atmosphere is becoming a better insulator, thus, preventing heat
from escaping back into space. That is why there is a global rise in
temperature which scientists refer to as " global warming". As a
result of this rise in temperature the world food supply and sea level will be
affected, also there is the probability of increase in the tropical
disease.
