(Group Discussion)

I. OBJECTIVES

At the end of the lesson, the student are expected toa. Define pollution

b. Enumerate and discuss the different types of pollution

c. Give ways to avoid pollution

II. SUBJECT MATTERA. Topic: Pollution

B. Reference:C. Materials:

C.1. For teachers: Visual aids, Chalkboard and chalk

C.2. For students: Book, paper and pen

D. Teaching strategy: Group Discussion

III. PROCEDURE

a. Preliminary Activitiesa.1. prayer

a.2. Greetingsa.3. classroom conditioning

a.4. checking of attendancea.5. checking of assignment

b. Recall:

c. Motivation: The teacher will show an audio visual presentation of todays problemabout pollution.

d. Presentation:d.1 Give the meaning of pollution

Pollution is the introduction ofcontaminants into the natural environment that causeadverse change. Pollution can take the form ofchemical substances orenergy,such as noise, heat

or light.Pollutants,the components of pollution, can be either foreign substances/energies ornaturally occurring contaminants.

d.2.Enumerate and discuss the different types of pollutionAir pollution:- the release of chemicals and particulates into the atmosphere. Common

gaseous pollutants includecarbon monoxide,sulfur dioxide,chlorofluorocarbons (CFCs)

andnitrogen oxidesproduced byindustry and motor vehicles. Water, by the dischargeofwastewater from commercial andindustrial waste (intentionally or through spills) intosurface

waters;discharges of untreated domesticsewage,and chemical contaminants, such aschlorine,

from treated sewage; release of waste and contaminants into surfacerunoff flowing to surface

waters (includingurban runoff and agricultural runoff, which may contain

chemicalfertilizers andpesticides); waste disposal and leaching

intogroundwater;eutrophication and littering.d.3. Give ways to avoid pollution

Pollution control is a term used inenvironmental management.It means the controlofemissions andeffluents into air, water or soil. Without pollution control, the waste productsfrom consumption, heating, agriculture, mining, manufacturing, transportation and other human

activities, whether they accumulate or disperse, will degrade theenvironment.In the hierarchy of

controls,pollution prevention andwaste minimization are more desirable than pollution control.In the field ofland development,low impact development is a similar technique for the

prevention ofurban runoff.

d. Generalization:Pollution is the introduction ofcontaminants into the natural environment that cause adverse

change. Pollution can take the form ofchemical substances orenergy,such as noise, heat or

light.Pollutants,the components of pollution, can be either foreign substances/energies ornaturally occurring contaminants.Air pollution:- the release of chemicals and particulates into

the atmosphere. Common gaseous pollutants includecarbon monoxide,sulfur

dioxide,chlorofluorocarbons (CFCs) andnitrogen oxidesproduced byindustry and motor

vehicles. Pollution control is a term used inenvironmental management.It means the controlofemissions andeffluents into air, water or soil. Without pollution control, the waste products

f. Application

Group the students into five and let them discuss some practices that will avoid

pollution and its benefits to the society.
