Question1 Which of the following statements about pollutant are true: A Pollutant only harmful for humans B Pollutants alter the environment in a negative way C Pollutants refer specifically to toxic inorganic substances made by humans D Pollutants are harmful organic substances that negatively effect plants and animals Question2 The following are all atmosphere pollutants, with one except Choose the exception: A Carbon monoxide B Nitrogen dioxide C Nitrogen gas D Ozone Question3 Which one of the following is an example of a diffuse source of pollution? A highway carrying heavy traffic B chimney stack C sewerage pipe D pipe discharging waste from a manufacturing plant Question4 Air pollution affects to? A human health B animals C plants D all A, B, C are correct Total mark 10 mark mark mark mark mark < mark 42 10 21 • Divides the class into groups.: Group 1(12 students From to 12 in the list of the class) Leader : HOANG DUC AN Vice: NGO NGOC ANH Group 2(12 students From 13 to 24 in the list of the class) Leader : BUI THANH HUYEN Vice: TRINH VIET HOANG Group 3(12 students From 25 to 36 in the list of the class) Leader : VU THUY LINH Vice: PHAM THI LINH Group 4(12 students From 37 to 48 in the list of the class) Leader : TRAN HAI YEN Vice: MAI THANH XUAN • States the assignment obviously Group 1: What is the air pollution? How many kinds of air pollution? Group 2: The causes of air pollution Group 3: The affects of air pollution Group 4: The solution to protect the environment 1.2 Students: • Get the assignment • Work in groups at home or during the break at school to search for the information needed • Exchange and make a complete report • Prepare questions to ask other groups in the coming session Procedure: 2.1 Warm- up: Teacher introduce about the topic of extra-curricular session: The air pollution - Teacher shows four questions that related to the environment and gave to the students to prepare at home - Teacher calls leader of each group to answer - Teacher gives feedback and comment - Teacher leads to topic and announces the extra- curricular session starts 2.2 Presentation The representative of each group will present what they have collected in front of the class and the rest listen to them carefully 2.2.1 Group Presenter: HOANG DUC AN The content: The definition of air pollution HOANG DUC AN: First, I present the definition of pollution Pollution is the introduction of contaminants into the natural environment that cause adverse change, in the form of killing of life, toxicity of the environment, damage to ecosystem and aesthetics of our surrounding (Wikipedia) Pollution has become a serious issue after World War II in developing countries due to unchecked rapid industrialization Pollution is the root cause of many diseases that kill and disable living organisms Picture 1: A broader view of pollution Air pollution is contamination of the indoor or outdoor environment by any chemical physical or biological agent that modifies the natural characteristics of the atmosphere Air pollution is the introduction of chemicals particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment into atmosphere A substance in the air that can cause harm to humans and the environment is known as air pollution 2.2.2 Group Presenter: BUI THANH HUYEN The content: The causes of air pollution Air pollution can result from both human and natural action or out door pollution and indoor air pollution Picture 2: The causes of air pollution 2.2.2.1 Natural air pollution: Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity All these things are examples of serious air pollution that happen without any help from humans; although we can adapt to natural air pollution, and try to reduce the disruption it causes, we can never stop it happening completely For the rest of this article, we'll consider only the "unnatural" types of pollution: the problems that people cause—and the ones we can solve Picture 3: Forest fires are one completely natural cause of air pollution 2.2.2.2 Traffic In Vietnam, air pollution is rising at an alarming rate, especially in big cities such as Hanoi and Ho Chi Minh City Air pollution can result from transportation, industry, handicrafts and construction activities According to the experts, air pollution in urban caused by traffic accounts for 70 % According to reports on ambient air situation for the period 2008 -2012, NO (nitrogen oxide) tends to increase in the rush hours in the morning and afternoon The concentration of dust parameters tend to remain at high level, especially along the roads and highways with high traffic density Dust pollution around construction sites is relatively serious and maintains at high level for long period of time during the construction period Picture 4: Air pollution in Ha Noi 2.2.2.3 Exhaust from factories and industries Manufacturing industries release large amount of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air thereby depleting the quality of air Manufacturing industries can be found at every corner of the earth and there is no area that has not been affected by it Petroleum refineries also release hydrocarbons and various other chemicals that pollute the air and also cause land pollution The Ozone layer considered crucial for the existence of the ecosystems on the planet is depleting due to increased pollution Global warming, a direct result of the increased imbalance of gases in the atmosphere has come to be known as the biggest threat and challenge that the contemporary world has to overcome in a bid for survival Picture 5: Air pollution from factories and industries 2.2.2.4 Indoor air pollution Household cleaning products, painting supplies emit toxic chemicals in the air and cause air pollution Have you ever noticed that once you paint walls of your house, it creates some sort of smell which makes it literally impossible for you to breathe Suspended particulate matter popular by its acronym SPM, is another cause of pollution Referring to the particles afloat in the air, SPM is usually caused by dust, combustion etc The National Health and Medical Research Council (NHMRC) defines indoor air as air within a building occupied for at least one hour by people of varying states of health This can include the office, classroom, transport facility, shopping centre, hospital and home Indoor air quality can be defined as the totality of attributes of indoor air that affect a person's health and well being A major concern with respect to indoor air quality is the use of gas cookers and unflued gas heaters These two sources can often contribute a large percentage of the pollutants found in domestic dwellings Increasingly, as dwellings have become better sealed from the external environment, pollutants being released from indoor sources are being found at higher concentrations Picture 6: Indoor air pollution 2.2.3 Group Presenter: VU THUY LINH The content: The effects of air pollution The nature of air pollution has changed over the past 40 years Emissions of smoke and sulphur dioxide associated with smog of the past have declined, while the proportion of pollution from vehicles has increased The health effects of air pollution are still, however, significant Evidence from the Government’s Committee on the Medical Effects of Air Pollution (COMEAP) suggests that some 29,000 deaths per year (4,000 in London alone) are brought forward by exposure to man-made particulate air pollution at current levels Their current work suggests that a similar scale of premature deaths are caused by NO2 pollution, although further work is being carried out to establish to what extent these impacts overlap 10 Picture 7: causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground level ozone concentration, (6) increased levels of nitrogen oxides The effects of air pollution are alarming They are known to create several respiratory and heart conditions along with Cancer, among other threats to the body Several millions are known to have died due to direct or indirect effects of Air pollution Children in areas exposed to air pollutants are said to commonly suffer from pneumonia and asthma 2.2.3.1 Effect on Human health We know air pollution is a bad thing without even thinking about it Have you ever coughed when a truck drove past belching out its sooty exhaust? Instinctively, you cough to clear your lungs and protect your body and you might even cover your face with your handkerchief or sleeve to filter the air until it feels safe to breathe deeply again You don't have to be told that pollution like this might harm your health to want to steer clear of it: your body takes action automatically The only trouble is, we can't always see or smell air pollution, tell when it's affecting us, or know how it might harm us days, months, or even years in the future Deaths aren't the only human consequence of air pollution For every person who dies, hundreds or thousands more suffer breathing problems such as asthma and bronchitis Workers exposed to high levels of dust sometimes suffer years of misery before dying from illnesses such as silicosis 11 Picture 8: Effects of pollution on human health According to the World Health Organization (WHO), air pollution is one of the world's biggest killers: it causes around two million people to die prematurely each year Many of these deaths happen in developing countries (over half a million in India alone), but wealthier industrial nations suffer too: in the United States, for example, around 41,000 people a year are estimated to die early because of air pollution Imagine how much media coverage there would be if two million people (that's roughly the population of Houston, Texas or the West Midlands conurbation in England) were killed in a terrorist incident or an earthquake Because air pollution kills quietly and relentlessly, and its finger is hard to detect on the trigger, people barely seem to notice—or care 2.2.3.2 Effect on agriculture and plants Pollution from car exhaust, factory emissions, fuel combustion and other sources can hang a brown cloud over some cities Air pollution not only contributes to respiratory diseases in humans and damages buildings, it can also affect plants The effects of air pollution on plants develop over time and can't be undone Some plants are more susceptible to pollution damage than others according to Fred Davis, a chemist from Kent State University 12 Chemicals such as sulfur dioxide, ozone, fluorides and peroxyacyl nitrate damage the leaves of plants If enough leaves are damaged, the entire plant will die Sulfur dioxide, a by-product of burning fossil fuels such as oil, coal and gasoline, causes changes in the colors of leaf tissue Some sulfur dioxide converts to sulfuric acid, which eats holes in the leaves Ozone damage on leaves appears as mottled spots, which may be yellow, black or brown 2.2.3.3 Other effects Acid Rain: Harmful gases like nitrogen oxides and sulfur oxides are released into the atmosphere during the burning of fossil fuels When it rains, the water droplets combines with these air pollutants, becomes acidic and then falls on the ground in the form of acid rain Acid rain can cause great damage to human, animals and crops Depletion of Ozone layer: Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays Earth’s ozone layer is depleting due to the presence of chlorofluorocarbons, hydro chlorofluorocarbons in the atmosphere As ozone layer will go thin, it will emit harmful rays back on earth and can cause skin and eye related problems UV rays also have the capability to affect crops Global warming: Another direct effect is the immediate alterations that the world is witnessing due to Global warming With increased temperatures world wide, increase in sea levels and melting of ice from colder regions and icebergs, displacement and loss of habitat have already signaled an impending disaster if actions for preservation and normalization aren’t undertaken soon 13 Picture 10 : Effect of acid rain Effect on Wildlife: Just like humans, animals also face some devastating affects of air pollution Toxic chemicals present in the air can force wildlife species to move to new place and change their habitat The toxic pollutants deposit over the surface of the water and can also affect sea animals 2.2.4 Group 4: Presenter: TRAN HAI YEN The content: The solutions to reduce air pollution * Government: - Government throughout the world should have already taken action against air pollution by introducing green energy - should invest renewable resources: wind power, solar energy to minimize burning of fossil fuels - should enact laws forcing companies to be more responsible with their manufacturing activities so that they are a lot controlled - should provide local transport to people to reduce burning fossil fuels * I and you: There are simple steps we can take in our everyday life to help improve air quality Every time you drive to work or school, use your heater or air conditioner, clean your windows or even style your hair, you make choices that can reduce or increase air pollution 14 On the road: - Walk or ride a bike when possible - Take public transportation - Organize and condense errands into one trip - When driving, accelerate gradually and obey the speed limit - Drive less, particularly on days with unhealthy air - Travel lightly and remove any unnecessary items that may weigh down your vehicle - Limit idling your vehicle to no more than 30 seconds - When in the market for a new car, look for the most efficient, lowest-polluting vehicle or even a zero-emission electric car At home: - Turn the lights off when you leave a room - Replace energy-hungry incandescent lights with compact florescent light bulbs - Ask your energy supplier for a home audit and inquire about alternative energy solutions like solar or wind - Option for a fan instead of air conditioning - Plant a tree! They filter the air and provide shade - Let your elected representatives know you support action for cleaner air - Choose products that use recycled materials - Eat locally, shop at farmers markets and buy organic products - Buy products from sustainable sources such as bamboo and hemp At Work: - Start a recycling program - Print and photocopy on both sides of paper - Turn off office equipment, computers, printers, and fax machines, after hours - Harness the power of the sun: open the blinds and turn off the lights - Dress for the weather and adjust layers before adjusting the thermostat 2.3 Practice Teacher lets students to play a game: WHO IS THE WINNER? Before playing, the students listen to the teacher’s explanation: There are six numbers Teacher will give five questions in five box and one box is lucky number that give you 10 points without answering The leader of each group will choose the questions and have minutes to prepare and answer If the answer is wrong, the other will have a chance to answer and get points Each a correct answer will have 10 points prepared carefully In the end, which group gets the highest score will be the winner 15 Question 1: Is air pollution a substance in the air that can cause harm to humans and the environment? Expected answer: Yes Question 2: What cause the air pollution? A: human action B: natural action C: both human and natural action Expected answer: C Question 3: In Viet Nam, Which cities be affected the best by air pollution? Expected answer: In Hanoi and Ho Chi Minh city Question 4: According to the World Health Organization (WHO), How many people are died by air pollution each year? Expected answer: two million people each year Question 5: What can Acid rain great damage to? Expected answer: human, animals and crops 2.4 The result: After playing the game, the points of each group: Group 1: 20 points Group 2: 10 points Group 3: 30 points( the highest score) Groups 4: point Group will be winner Acquirement After the session, Teacher hands out the questions to check the students’ acquirement Asks students to circle the correct answers in minutes then collects and marks, jots down and analyses the result Compare the result before and after the extra-curricular session The result before the extra-curricular session Total 49 mark 10 mark mark 17 mark 21 mark mark < mark mark mark < mark The result after the extra-curricular session Total 49 mark 10 15 mark 22 mark mark 16 As can be seen from the tables above, the knowledge of the students in class 10A2 was greatly enhanced The excellent marks (9,10) increased from to 37 Especially, no mark was lower than It is clear that The English extra curricular session was definitely successful PART C CONCLUSION Through the practice of the extra-curricular session, it is obvious that the students of class 10A2 are definitely concerned about the topic “Raise students’ awareness of protecting the environment through studying about the air pollution ” They are eager to study and search for the information needed to achieve deeper understanding about the issue Much as it is quite a hard topic, they quickly lose themselves in their duties and get a rather good result They are fully aware of their duties at present: study, study more, study forever to become good citizens to constitute and protect the country The above composition is a report of an English extra-curricular session It can not help making mistakes although I have attempted to finish it Therefore, I would like to express my deep thanks to all of you for your precious ideas to make my teaching session more perfect Thank you so much!
