good day guys welcome to another YouTube

video from exam bonance YouTube channel

I enjoin you guys to subscribe to this

YouTube channel like our video and

comment wherever necessary so today we

are going to be discussing TR4 W agre

practical specimen before I go straight

to the point if you have any quaries you

want to make on the train you can visit

our website at ww. exam.com or Whatsapp

us at 093 2347 2 3 2 3 so we are going

to be discussing 24 PR specimen in this

video I will start with identification

of the specimen specimen a is ranging

pole specimen B Arrow specimen C

measuring tape specimen D wooden Peg

specimen e dry sand speci F dry clay

speci G dry L specimen H maze w speci i

Bean J grasser K hoton stain l tilapia

specimen m h speci n fish me so in this

video I'm going to be leaking the

questions that will come out in your

exam or should I say the probable

question the question that you should be

expected so we are going to discuss

expected questions question you should

expect your agre practical exam so let's

analyze this testment before I start

muring some questions a normal question

you should expect in your exam is

identification of specimen which we have

done already so in the exam your

specimens will be labeled by your

teacher and you be told to identify them

so they will label them A B C D E F G H

I J K L M N so you the one that will be

identified as what as ranging pole as

Arrow

so if you look at specimen a b c d they

are all survey surveying tools or you

can say surveying equipment ranging pole

is a surveying equipment arrow is a

surveying equipment measuring tape is a

surve equipment wooden Peg is a surve

equipment so now I want to discuss

about ranging pole so I'll be talking

about ranging pole so looking at all the

surve equipment the most common

questions that will come out exam is I

they to describe give a detail

description about the specimen the uses

of the specimen and the maintenance

practices of the specimen so let's start

with ring pole so if you are told in the

exam that let's say your question a i i

is give a detailed description of

specimen a your answer should be

specimen a is a Sur to that is straight

you should know that your ring pole is

what is straight so in the exam don't

say ranging pole is straight you say

specimen a is what is a surveying to

that is straight you don't need to

mention the specimen while answering the

question so your answer will be speci if

you are told to answer the question of

give a detail description of specimen a

your answer should be specimen a is a

surve tool that is straight round it is

a round drao or p and you should know

that it has a pointed metal Tee It is

painted in alternative bound of color

such as red and white it is us about 6 M

long

so you'll be told to give a detail

description of your specimen and what

I've said is what you should do if you

are watching this video you can get your

J and your P so can be jotting down

vital points it is very important so

let's go to another question so I've

given you the detailed description of

specimen a it is a straight round Rod or

pole it has a pointed metal end it has

alternative band of colors which usually

red and white and then it is about 6 M

long that is the description of a r p

then another question they can ask you

in the exam is you should give uses of

specif a that is uses of ring pole one

of the uses is it is used for marking

stations another uses is used for making

straight line for marking straight lines

another use is it is used to Mark points

that need to be visible from a distance

so specimen a is used to Mark point that

need to be visible from a

distance then another important question

you should know that they can ask under

specimen a is the maintenance practices

I will tell you some common maintenance

practices in this this are practical

exam is one of the simplest practical

exam because maintenance practices for

most tools and equipment are usually the

same thing just that if the metal if the

instrument does not have a metallic

part oiling of metal part will not be

part of the maintenance partes but if it

has a metal part oiling or greasing or

metallic part part of the maintenance

part

and let's take the maintenance

practices number one maintenance

practice you know you should clean the

instrument after use you should clean

speci after use another one is that you

should store it in what in a dry and

cool

place then you should sharpen the metal

end I I already told you that it has a

what a metallic end so you should

sharpen sharpen like sharpen s h a r p e

n sharpen a met end then another

maintenance practices practice is we

should oil or Grease the metallic parts

so when I was talking about the

description of the r po I told you it

what it has a pointed metallic head so

that metallic head is the part that you

grease is also the part that you

sharpen so another maintenance PR I say

precaution is also part of Maintenance

par if told to mention more than four

maintenance pares the instrument should

be handled by competent person that is

also a maintenance practice it should be

handled by competent

person that maintenance practice I give

to you on R po still applies for Arrow

it still applies for the arrow so you

should use the the same maintenance

pares for what for ranging pole and

arrow because Arrow also has a metallic

head so moving on to uses of specimen B

so I want to talk about the uses of

specimen B it is used Don

shaning for marking off length

shanes that is your number one uses of

Arrow another uses it is used for

marking stations it is used for marking

station on for marking point of

intersection you have given you three

uses of Arrow number one is used Shing

for marking off length used for marking

station and is used for marking point of

intersection

so I already to the common question in

the exam you should be expecting

identification of your specimen that is

a bonus question so I'm going to be

talking about specimen C which is our

measuring tape a very common use of

measuring tape is is used for taking

measurement of length height or bread or

distance that is number one uses of

specimen C another use of specimen is it

is used in determining the right angle

triangle ding Farm layout so ding Farm

layout usually determine the right angle

triangle of the farm so a use of

measuring tape is that it is used in

determine the right angle triangle ding

Farm

layout so I'm going to move on to

another question that they can ask under

specimen C because we are still under

specimen C maintenance practices of

specimen I already told you that most of

these um tools they have the same

maintenance practices number one

maintenance practices of measuring tape

is that store in a dry cool place one

another maintenance practices is you

should clean the instrument what after

use on maintenance practices is that

retract the tape slowly after use into

its case you know the way our measuring

tape looks like now so after using your

measuring tape you should retract it you

should return it slowly inside the what

inside the case so I've given you three

maintenance pares of specific see number

one store in a dry cool place number two

clean after use number three retract the

tape slowly after use into it

case before I let's before I forget

there's another important question they

can ask you that should give a

description of specimen C that is your

measuring tape your description should

go like this specimen C is made up of

plastic with a flat circular

case made up of

metal into which the tape is rolled into

after use so the description of

measuring tape is very very simple it's

made up of plastic with a flat circular

case made up of metal into which the

tape is rolled into after use so that is

a very very short and deta description

of specimen

C so I want to give you the description

of specimen D that another question you

can be asked in the exam it is a wooden

rectangular stick with pointed

cage with pointed

Edge to Ed stocking into the ground you

know we are talking about wooden Peg

those wooden Peg they us stocked into

the ground so it is a wooden rectangular

stick with pointed Edge to Ed stocking

into the ground so it is the pointed

Edge stuck into the ground that is the

description of speci is a wooden

rectangular sck with pointed Edge to

stuck into the ground so it's made of

the material is wooden that's is the

description it has a pointed Edge that

is the description so the other parts

are not necessary what you should know

that the wooden Peg is what it is

rectangular it is wooden and it has a

pointed Ed that is three points so that

is three

marks then another question on wooden

Peg they can ask you that you should

state two uses of wooden Peg it is used

for marking points that is number one

using of wood P that specimen used for

marking points another use that it is

used for tying rops in making straight

lines so when you want to make straight

lines on the farm you can tie you can

use specimen D to tie ropes so I give

you two uses of specimen use the marking

Point using tying ropes in making

straight

lines then let's go to question number

two of your agre practical specimen so

your question number two you be told to

identify specimen EFG so you be giv

those so physically is through the

colors you can be able to distinguish

and the way the particles are the

texture of the particles so you be giv

dry sand dry clay and dry low so the

question will go through a experiment I

will not talk much on that I will not

talk much on that so you be given an

experiment so it's true that experiment

you derive question for from that

experiment so the experiment will not be

not be a very hard experiment like that

just a little experiment the setup might

be there already so they just be asking

questions based on the diagram in the

question so let's go to identification

of specimen h j KL so looking at

specimen h j

KL before I go there let me say

something more on specimen EFG so we

have different experiments when I'm

talking about soil in agre can be told

to determine the population ratees can

be told to determine

the organic content in the soil to be

determine the water the way the

absorbing rate of water of the soil so

there are different experiment they can

ask you on specimen EFG those are just

so basically they can tell that should

differentiate between e FG in a tular

form the T form might be already

so I want to move on to speci h j k so

question that ask speci H number one is

identify the

specimen so after identification the

specimen speci H is specimen I is being

specimen J is grasser specimen K is

cotting

stainer they can ask you to State the

economic importance of each of these

specimen we should know that all of them

have the same similar economic

importance except for C ST which is not

a food

but it has a similar economic importance

with all other ones so let's take

specimen H into consideration a common

economic importance of all of them is

food

shortage due to destruction of the food

in which they attack specimen H attack M

so food food shortage due to destruction

of what of mze

grain ey attack

bans food shortage due to destruction of

what of B

sixs

then let's focus on H and I only let's

focus on H and I only so another

economic importance of H and I is that

destruction of seed viability when I

talking about seed viability talking

about the potency of the seed the way

the seed will germinates the viability

of the seed so if P infest those grains

the viability of the seed will what will

be reduced so another another economic

importance is what ruction of seed

viability another economic is reduce

market value and loss of income so if

the market value of the GRE are reduced

if the seed or the food if B gra have

holes the be seed have holes when you

get to the market you not like to pay

price for something that is having hes

so it will reduce the market value and

also reduce the what the income of the

what of the

farmer another economic importance of M

and being is reduced quantity of you you

know when pet infest those CRS on the

farm the yield of the prob will be what

it will be reduced the quantity of you

will what it will be reduced another

important economic importance of mze w

and being is increase cost of production

so how can being mze W and be to

increase cost of production in the

process whereby the farmer is trying to

control pest on the farm he has to buy

insecti side so buy insecticide will

increase the cost of production of the

crop because normally you should just FL

the CR and get out of there but now it's

going to be buying what insecticides

buying pesticides buying herbicides so

all these insecticide and P control

mechanisms methods will increase the

what the cost of production thereby

increasing the what the cost of the

goods so now we have talked about

specimen H and I very well so now we

should talk about specimen

J which is the grasshopper and we also

talk about

specimen K which is cotton St up I will

not talk too much on that but before

that let's talk about ways of

controlling specimen

H so I have seven ways of controlling

specimen H here with me I'll be giving

you the seven but in the exam you should

know that they will not ask more than

five you just need to know like five out

of the seven number one use of dry hot

pepper so you can use paper to control

maze you can also store your maze in a

hair tight container storing it with

what we control the what maze W maze W

will not be able to penetrate through

the what through the container if it is

what hair

tight use of appropriate insecticides so

use of appropriate insectic side can

control maze W since maze W is a what is

an insect so the best chemical to use to

control chemical method is what insc

inside

another way of controlling maze is early

harvesting so if we advest our maze

early on time maze will not be able to

infest our crops our seed maze seeds

figting maze in store so when we store

our maze most times when mze attacks our

mze Braes in the storage room or when

it's in storage so the next Point ways

of controlling meable is use of deep

freezer so we can use deep freezer to

control maze W as those maze will not be

able to survive under very low

temperature same goes for heat treatment

so heat treatment is also another way of

controlling mze the way M canot survive

at extremely low temperature they can

also survive under what extremely high

temperature there's a level of

temperature that if you increase heat if

there's heat applied you will not be

able to survive in such environment so

heat treatment is also another way of

controlling m

then another question you should be

expecting your exam is mention three

ways in which specimen I is economically

important we have talked about that

already is to said destruction of

viability destroys the viability of seed

reduces market value of crops food

shortage increase cost of production due

to cost of

pesticides or insecticides so that is

that I already said that before now that

if you want economic

importance of the to the both m and b

are having the same economic importance

very similar economic importance they

can go interchangeably so the next

question I want to talk about I want to

take specimen

HK specimen HK I want to take the four

of them into consideration now a

question that can cover the four

specimen together at

once you can be asked in the exam that

you should mention the feeding habit of

specimen h i j

k when they talk about feeding habit

they're talking about their mouth Parts

the way they shoe is it sh and biting is

it biting and Sh is it boring is it

piercing and sucking is it sh only is it

boring

only so let's start with

spe specimen H is our M and the feeding

habit is biting and showing biting and

Sh so m is biting and Sh say eye is

being be and the feeding habit is boring

is a boring pest

boring so it BS all into the what into

the beans so the next specimen specimen

J grasshopper and the feeding habit is

biting and showing biting and showing

specimen K is our cutting St that's the

only specimen there that the only

organism there that is a piercing and

sucking speci K is what cotton stainer

and a person talking only attach cotton

crops cotton

plants so that is specimen K so that is

all on specimen h j k I'm going to be

moving to specimen LMN

now the specimen n is the tilapia

specimen M he specimen n fish meal so in

the exam you can be told to draw speci

that is your spia you might be told to

draw specimen l so make sure you go to

the exam with your HB pencil and your 2B

pencil your HB pencil for drawing the

specimen your person for what for

labeling the specimen not very comp make

sure you go with a well sh person for NE

drawing the next question here is

question 3 b i i l four characteristics

of specimen L which makes curable so

specimen L is our tilapia told that we

should list four characteristics of

which makes it curable I'm going to be

giving you six

characteristics so you can just pick

five and CR

it the first characteristic that ability

to breed in captivity so one of the

characteristics of tilapia that makes it

culturable is that it can breed in

captivity another characteristic that it

toates poor water quality po water

quality when I talk about po water

quality if the thing is low oxygen

tilapia will not survive very well there

but the water quality is poor and it has

a good oxygen supply there enough water

oxygen then the tilapia Will Survive

there so specimen is able to survive a

water with what with poor water quality

another characteristics of specimen air

that makes it curable is that it is

acceptable to Consumers we all eat

tilapia fish so it is acceptable to

Consumers

another that makes it

that it has high resistance to diseases

that means it the tilapia fish they

don't just contract diseases anyhow so

they have high resistance to diseases

another characteristic that makes it

culturable is that early mature it

matures very fast tilapia fish they grow

very fast early maturity matures very

early another that makes it cultur it

accept artificial feed so those feeds

that are being sold in various shop fish

feed tilapia fish accept artificial feed

so I have

discussed specimen L well very well

enough specimen a m you should need that

specimen m is a feed hay hay is dry

grass so dry grass so they bundle it

together so that is what it's called ha

he are used to prepare feeds for

different animals so that's your

specimen m is hay hay is a food we don't

call it food when Greek when it's for

Animals you call it what feed not food

feed so another question you should

expect in your exam is that how can you

prepare specimen and from speci so you

want to prepare fish meal from

tilapia specimen from speci so how can

you prepare your tilapia into fish meal

number one step there are six steps

there number one is that you should cook

your water specimen L your tilapia you

should cook it step two is what you

should press it so when you press it the

oil will come out of it and water what

is come out of it the third step is

separate the liquid into oil and water

so we going to be separating the oil

from the tilapia from the what from the

water the next step is evaporate the

water into a concentrate the next step

is what is to dry it then the last step

is to what grind it and then we have our

what our fish meal so I give three step

there number one cook number three press

number three step separate number four

step evaporate number five step dry

number seven six step grind so I've giv

you six step so these are all you need
