Assignment on Pollution

Introduction

Environmental pollution is a multi-disciplinary science involving chemistry, physics, life science, agriculture, medical science, public health, sanitary engineering etc. In broader sense, it is the study of the sources, reactions, transport, effect and fate of chemical species in the air, water and soil and the effect of human activity upon these.

Pollutant : A substance present in nature, in greater than natural abundance due to human activity, which ultimately has a detrimental effect on the environment and therefrom on living organisms and mankind. Examples are- lead, mercury, sulphur dioxide, carbon monoxide, etc.

Contaminant : A material which does not occur in nature, but is introduced by human activity into the environment, affecting its composition. A contaminant is classified as a pollutant when it exerts a detrimental effect. Example- chlorine gas

Types of Pollution

Causes of air pollution:

  • motor vehicle exhaust
  • power stations
  • car manufacturing
  • fertilizer factories
  • demolishing buildings
  • solvent evaporation
  • volcanic eruption
  • building roads
  • forest fires

Effect of air pollution:

Global warming, acid rain, smog, ozone depletion are some effects of air pollution

Causes of water pollution:

  • man-made chemicals used in farming
  • heavy metals
  • waste from factories
  • sediment from the river bed
  • air pollution
  • thermal (heat) pollution
  • soil pollution from rubbish dumps

Effects of water pollution:

The water in the earth’s biosphere is used and reused again and again by all living things

Soil Causes of soil pollution:

  • mining and quarrying
  • household waste
  • demolition and putting up buildings
  • factory waste

Effects of soil pollution:

Experts say that lots of land each year becomes unusable for humans or animals.

Causes of noise pollution:

  • noisy roads and traffic
  • air traffic
  • rail traffic
  • household noise
  • industrial noise

Effects of noise pollution:

We hear and make sounds nearly all the time but too much noise can make us feel angry or depressed. The time of day that noises are heard is very important.

Radiation Pollution from radiation can be caused by:

  • nuclear power plants
  • making nuclear weapons
  • disposal of nuclear waste
  • mining for uranium

What can happen?

Radiation occurs naturally at low levels and is a useful source of power when concentrated.

It can also be very harmful to all living things if they are exposed to too much of it.

Light pollution happens when outside lights, such as a streetlight or a security light, points light upwards into the night sky.

This light gets scattered in the sky and makes an orange foggy glow to appear above a town.

It is likely that we won’t be able to see the stars in the night sky if the amount of light pollution isn’t closely controlled.

CONSERVATION AND ENVIRONMENT MANAGEMENT

It is imperative that we carefully utilise our renewable resources of soil, water, plant and animal life to sustain our economic development. Over exploitation of these is reflected in soil erosion, siltation, floods, and rapid destruction of our forest, floral and wildlife resources. The depletion of these resources often tends to be irreversible and since the bulk of our population depends on these natural resources to meet the basic needs, it has meant a deterioration in their quality of life.

Global petroleum deposits are likely to be exhausted within this century. Research is going on for alternatives to fossil fuel (petroleum) based on biomass (green energy). Controlled nuclear fusion holds the prospect of abundant energyif the relatively difficult deuterium-deuterium fusion reaction can be utilised for energy production. This energy source will become unlimited.

Solar energy is both renewable and non-polluting and provides ideal energy source. On a global scale, tapping of only a small fraction of solar energy the earth can supply the entire energy requirement.

In any new development project, due consideration must be given to the environmental, social and cultural impacts. For this purpose, environmental experts must be involved in project planning.

NATURAL AND MANMADE DISASTERS

Sometimes there are drastic changes in environment due to natural disasters, e.g. cyclone, typhoon, hurricane, tornado, earthquake, volcanic eruption etc. within a short time.

Bush fires , are another type of natural disasters, are of common occurrence in some regions of the world due to hot summer and lightning. During the hot summer months bush fires are common in Australia and in the Pacific coast arid areas in USA.

Man developed science and technology but over the years since the Industrial Revolution (1780- todate) he continued to plunder natural resources thereby polluting the environment. He degraded lands, destroyed forests, threw toxic wastes into rivers and seas and also harmful gases into the atmosphere. This continuous load of manmade pollutants into environment brought about adverse changes, which ultimately back-fired into series of disasters from time to time.

Some examples of manmade disasters are: London smog, Minamata disease, nuclear explosions, Bhopal disaster, Chernobyl disaster and Gulf War Hazards.

Nuclear Explosions . Two bombs were dropped by USA during World War II (Aug 6 and 9, 1945) on Hiroshima and Nagasaki in Japan. These instantly killed about 6 lakhs people, wiped out the two cities and unleashed radioactive fallout which has caused generations to suffer from various diseases including genetic disorder. Radiation continues to damage plants, soil and biosphere* in the region.

*the environment consists of four segments- atmosphere, hydrosphere, lithosphere and bioshphere.

Global Warming or Green House Effect

Among the constituents of the atmosphere, only carbon dioxide and water vapour strongly absorb infrared radiation (14000 to 25000 nm) and effectively block a large fraction of the earth’s emitted radiation. The radiation thus absorbed by carbon dioxide and water vapour is partly re-emitted to the earth’s surface. The net result is that the earth’s surface gets heated up by a phenomenon called the greenhouse effect .

The current global trend in deforestation along with increased combustion of fossil fuels have a cumulative effect on the net increase in carbon dioxide content (present 356 ppm, 50%). Carbon dioxide has the potential to rival nuclear wars in terms of massive irreversible damage to the environment. It is the major greenhouse gas but there are other greenhouse gases- methane (CH 4 , 19%), chlorofluorocarbons (CFC, 17%), nitrous oxide (N 2 O, 4%) and water vapour (2%).

In september, 1980 scientists reported a large hole in the ozone layer over Antarctica. CFC was the prime suspect for causing ozone depletion. It was established that one molecule of CFC is capable of destroying one lakh O 3 molecule in the stratosphere. The extreme chemical stability and nontoxicity of CFCs enable them to persist for years in the atmosphere and to enter the stratosphere. Depletion of ozone layer above the earth surface helps to penetrate harmful rays from the sun to the earth .

Water Pollution

Water Pollution introduces students to the causes and effects of pollution in the water. Students will discover ways to prevent water pollution as well. The activity worksheet in particular will help them solidify their understanding of why pollution is bad and help them explain to others why they should likewise help keep the water clean.

There are several suggestions listed in the “Options for Lesson” section that you can take advantage of in your lesson. One such suggestion is to invite a guest speaker from the water company or a sewage plant to come speak with the students.

Description

Additional information, what our water pollution lesson plan includes.

Lesson Objectives and Overview: Water Pollution explores the negative effects of pollutants in our water sources. Students will discover some causes and effects of water pollution, as well as some ways to prevent it. By the end of the lesson, they should understand why it is important to keep the world’s H 2 O sources clean. This lesson is for students in 3rd grade and 4th grade.

Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. In addition to the handouts, this lesson requires colored pencils or markers, construction paper or poster boards, and scratch paper. You will also need to ensure students have internet access for researching purposes.

Options for Lesson

There are a number of suggestions in the “Options for Lesson” section of additional activities and tasks that you could incorporate into the lesson plan. One suggestion is to invite a guest speaker from the water company or a sewage plant to speak with the class and answer their questions. Another idea is to obtain a local or state map that shows various bodies of water and their sources. You could also use pH strips or some other kind of testing kit to test the quality of water samples that you gather from different sources. One last idea is to introduce students to developing countries that have problems with clean water and describe some solutions that people could use to filter it better.

Teacher Notes

This page provides an extra paragraph of information or guidance as you prepare the lesson. It stresses how important it is that students understand the effects of water pollution and points out that they could face these issues in their lives. Use the blank lines to write down any other ideas or thoughts you might have regarding the lesson material.

WATER POLLUTION LESSON PLAN CONTENT PAGES

The Water Pollution lesson plan contains four pages of content. The first page provides students with some background information on what pollution is and why it is bad. All living organisms need food, oxygen, and water to survive. The main source of oxygen for humans is the air. If that air is not clean, however, it can cause health issues. People with asthma, for instance, have a hard time breathing when the air is dirty. In some countries, the air quality is bad enough that people have to cover their noses and mouths with a mask.

The reason behind dirty air has to do with pollution. Pollution includes substances in the environment that are harmful or dangerous for living things. Besides the air, it can also affect water and the land in general. Different types of pollution include air, noise, land, and light. Some of these cause only minor issues, but others can lead to serious problems for all living things. One of the worst kinds is water pollution. Because water is a necessity of life for all living organisms, polluted water causes a lot of issues in the world.

Students will discover that the human body is about 70% water, which is why drinking water regularly is good for their health. The water we consume needs to be clean. Even for plants, if the water is unclean, the plants will die or become unhealthy to eat. Water makes up 70% of the Earth’s surface, most of which is found in the oceans. Ocean water is salty, so it’s not safe to drink. Only 1% of the water on Earth is fresh water, which we find in lakes, rivers, streams, and reservoirs. If these sources become polluted and dirty, there is even less safe drinking water.

Sadly, humans are the cause of much of the water pollution that exists. Polluted water is simply unsafe to drink. While humans should not drink salt water either, pollution in oceans is still bad. Humans may not be able to survive by drinking salt water, but the living organisms in the oceans can and do. Pollution is also bad for oceans because it can cause problems for all the aquatic life living in them.

When different particles, chemicals, and other substances cause water to become unsafe, the water becomes polluted. Sometimes those pollutants flow directly into the water from a factory. Other times, it flows indirectly from rainwater that mixes with farm chemicals or from construction sites or other places that release unsafe chemicals. All rainwater eventually seeps into the ground and flows into rivers, lakes, or streams. So if rainwater is polluted, the pollution will eventually affect the freshwater sources.

In some countries, unsafe drinking water is the leading cause of death. There are places in the world where people drink bad water because they have no other choice. They need water to survive. The pollution can happen naturally due to volcanoes, excessive algae, or silt from storms and floods. However, humans often contribute to the problem even more. Human causes include sewage, pesticides and fertilizers, chemicals, and trash.

Types of Pollution

The lesson lists eight types of water pollution: nutrients, surface water, oxygen depleting, ground water, microbiological, suspended matter, chemical water, and oil spillage. Nutrients pollution occurs when excessive algae and plant growth that takes place in water bodies release too many nutrients into the water. Too much algae, for instance, takes away the oxygen from the water, which means other organisms may die.

Similarly, oxygen depleting is when decaying matter is released into water, leading to more microorganisms that use up the oxygen. Some of these organisms even produce harmful chemicals that can kill other living things. Microbiological pollution happens when many people drink water directly from rivers or streams without first treating the water. The natural pollution in this water can cause illness to humans and other animals.

Suspended matter is when some pollutants do not dissolve in the water and instead sink to the bottom, killing organisms that live there. Chemical water pollution occurs when the chemicals people use end up in the water. It also includes metals and solvents from factories that are poisonous to aquatic life, which slows their growth, makes them infertile, or kills them.

Prevention Methods

Students will learn several ways that they can help prevent water pollution or assist in cleaning up polluted waters. Though some pollution is not possible to prevent, there are ways to help keep water clean. One of the first things we can do is inform others about the effects of polluted water and explain why keeping water clean is essential to survival.

The lesson lists several facts students could share with others to inform them of the issue. Around 14 billion pounds of mostly plastic garbage ends up in the water every single year. In the United States alone, 1.2 trillion gallons of sewage is dumped into the water each year. Nearly 90% of wastewater flows untreated into lakes, rivers, and coastal areas. Over 3 million children under the age of five die every year because of diseases caused by drinking polluted water and poor sanitation. Nearly 1 billion people in the world don’t even have access to clean water sources.

Students can then read through five suggestions of things they can do to prevent polluting water themselves. They can first reduce the amount of water they use when doing things like taking showers or brushing their teeth. They should also not dump paints, oils, medicines, or chemicals down the drain or into the toilet. Another suggestion is to encourage their parents to buy cleaning supplies that are eco-friendly. One other great option is to plant more trees and flowers.

WATER POLLUTION LESSON PLAN WORKSHEETS

The Water Pollution lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each one will help reinforce students’ comprehension of the lesson material. The guidelines on the classroom procedure page outlines when you give your students each handout.

PREVENTION POSTERS ACTIVITY WORKSHEET

Students will work with a partner for the activity. Using the supplies you provide, they will create a poster that encourages people to prevent water pollution. They will need to be creative and use words, images, logo, and slogans to demonstrate why this is important. In addition to a catchy title and the images and slogans, they should include facts that relate to the concept of preventing pollution. After they complete their poster, they will respond to three questions at the bottom of the worksheet.

MULTIPLE CHOICE PRACTICE WORKSHEET

For the practice worksheet, students will answer 10 questions. You can choose whether or not students can use the content pages for reference when they need help. This worksheet could also work well as a quiz if you want to test students on their level of comprehension.

WATER POLLUTION HOMEWORK ASSIGNMENT

The homework assignment has two sections. The first section contains 12 statements. Students must match the type of pollution from the word bank to the statements. They will use some terms more than once. The second section requires students to fill in the blanks in eight sentences. There is no work bank for this section, so students will need to remember what they learned during the lesson. However, like the practice worksheet, you may choose to allow them to use the content pages for help if they need it.

Worksheet Answer Keys

The last two pages of the lesson plan document are answer keys for the practice and homework worksheets. The answers are all in red to make it easy for you to compare to students’ responses. Because there are no open-ended or opinion-based prompts, students’ answers should mirror those on these pages. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.

Thank you for submitting a review!

Your input is very much appreciated. Share it with your friends so they can enjoy it too!

Great Resource!

I have to cover water pollution and it's not really covered in our textbook. I found this resource during a quick Google search and I am really happy with it! I printed everything out and scanned the reading portion to create a Google Classroom assignment, that I posted along with the links to to associated Learn Bright videos. Thanks for such a thorough and engaging resource!

Good experience!

I love using this site for my lessons. It helps me a lot not only for having those information from the text but also it can give us more ideas on how to teach some particular topics.

Water pollution

This was a well written lesson that went smoothly into the rest of the unit.

I just wish you might have some kid books that you would recommend to go along with this lesson. It's hard to do the internet here where we live so checking the online sources isn't really an option for us. Other than that my child enjoyed learning about all the ways water gets polluted.
