Q & A
Why is Dan cleaning his bike, and why do his hands also need cleaning afterward?
-Dan is cleaning his bike to keep it looking better, but after cleaning, his hands are dirty and need washing because cleanliness isn't just for appearance but also for hygiene.
What are microbes, and why are they harmful?
-Microbes are tiny living organisms that are everywhere around us. Harmful microbes, often called germs, can cause infections and make us ill by entering our bodies and multiplying.
Why is cleanliness especially important in hospitals?
-Cleanliness in hospitals is vital to prevent the spread of harmful germs, which can cause infections. This includes maintaining clean hands, clothing, linens, and sterilized medical instruments.
What experiment is performed in the hospital laboratory, and what does it demonstrate?
-An experiment using a culture plate is performed to show how soap with germicides prevents germs from growing. The untreated half of the plate grows colonies of germs, while the treated half remains clean, demonstrating the effectiveness of germicides in soap.
Why is it important to cover your mouth when you cough or sneeze?
-Covering your mouth when you cough or sneeze helps prevent the spread of germs from your mouth and nose to others, reducing the risk of infection.
How are medical instruments sterilized in hospitals, and why is this necessary?
-Medical instruments are sterilized using very hot steam in a sterilizer, which kills germs that even boiling water cannot destroy. This is essential to prevent infections during surgery or medical procedures.
What personal hygiene habits can help prevent the spread of germs?
-Personal hygiene habits such as washing hands with soap, not sharing food or drinks, keeping fingernails clean, and covering wounds with antiseptic can help prevent the spread of germs and infections.
Why do you need to wash with soap and not just water to clean your skin?
-Soap is necessary because it helps loosen and remove the oily mixture of dirt, germs, and waste on the skin, which water alone cannot effectively clean.
What is athlete’s foot, and how can it be prevented?
-Athlete’s foot is a fungal infection that thrives in warm, moist environments like the spaces between toes. It can be prevented by washing and thoroughly drying between the toes.
Why is brushing your teeth important for preventing tooth decay?
-Brushing your teeth removes food particles that germs in your mouth can feed on. If not removed, these germs produce acids that attack your teeth, leading to tooth decay.
Outlines
🧼 The Importance of Clean Hands and Germ Control in Hospitals
The first paragraph highlights the significance of cleanliness, particularly handwashing, to prevent infections. Dan cleans his bike, emphasizing the importance of washing hands afterward, as dirty hands are unsightly and unsanitary. The focus shifts to hospitals, where doctors wash hands to remove harmful microbes, also called germs, which cause infections. The paragraph explains how germs can multiply inside the body, leading to illness. The experiment with a culture plate demonstrates how liquid soap with germicides effectively prevents germs from growing, showing the critical role soap plays in germ control.
🚫 Avoiding Germs in Daily Life
The second paragraph discusses how germs can spread through everyday activities like sharing food, drinks, or handling unclean objects. It emphasizes the importance of rejecting such habits to avoid getting germs into the body. Germs thrive in warm, moist environments, such as inside a cut or broken skin, potentially leading to infection. The paragraph introduces the use of antiseptics to kill germs and encourages maintaining personal hygiene, including washing hands and avoiding unsanitary practices.
🧴 Personal Hygiene and the Science Behind Clean Skin
This paragraph explains the science behind skin cleanliness, using a cross-section diagram of the skin to describe how sweat and oil glands work. Sweat carries waste materials, and oil attracts dirt and germs, creating a layer of impurities on the skin. Water alone can't clean this mixture, but soap can penetrate the oil and remove dirt and germs. The importance of washing hair, scalp, and areas where perspiration is heavy is discussed, as is the value of using germicidal soap to kill germs. Special attention is given to washing between toes to prevent fungal infections and to keeping fingernails clean, as dirt under nails can harbor germs.

we like to keep the things that we own
as clean as we can
that's why dan is cleaning his bike
it looks much better now
but his hands don't now they need
cleaning
dan washes up because for one thing
dirty hands don't look very good clean
hands look much better
but these are different hands
a doctor's hands
and they're being washed for a more
important reason than appearance
the soap and water are washing away
microbes
microbes are the tiny living things that
are all around us
harmful microbes are usually called
germs
because germs cause infections and make
us ill
much attention is paid to cleanliness in
a hospital
this girl is one of the patients here
she's much better today
the infection that made her ill
began when diseased germs entered her
body and then multiplied inside it
there are many germs in your mouth and
nose even when you're not sick
that's an important reason for covering
your mouth when you cough or sneeze
in the hospital laboratory let's see
what some germs look like under a
microscope
another name for germs and other
microbes is microorganisms
that is tiny living bodies that can be
seen only through a microscope
now as an experiment
let's take a sample of the germs that
made this girl ill
we'll rub the cotton swab with the germs
on this culture plate
it contains food for the germs
the plate is divided into two parts
we'll treat half of the plate with
liquid soap
like some of the soaps we use every day
it has germ-fighting chemicals called
germicides in it
the other half of the plate is left
untreated
when the culture plate is placed into a
special kind of oven an incubator
the germs have not only food but warmth
and moisture the conditions they need
for growth
these are similar to conditions inside
your body
let's see what has happened after a few
days
well on the half that was treated with
the soap
nothing's happened
the soap with its germicides kept the
germs from growing but on the untreated
half there are white spots
each spot is a colony of thousands of
germs
so the use of soap can prevent germs
from multiplying and spreading
we've already seen how hands are kept
clean in a hospital
cleanliness of clothing is important too
clean uniforms are always worn
everyone who works with patients wears
clean clothing
clean uniforms for the people who work
in a hospital as well as clean linens
for the patients
means a lot of laundry
so the laundry room of the hospital is
quite an important place
into the huge washing machines goes all
the laundry
the soap and water will get it clean
but the high temperature of the water
and the germicides in the soap will also
destroy most of the germs
while washing machines get clothes and
linens clean
sterilizers get medical instruments
clean
inside the sterilizer very hot steam
kills germs that even boiling water
can't destroy
instruments used in surgery must have no
germs on them
so in a hospital to prevent the spread
of germs everyone is concerned with
cleanliness
cleanliness of the people
of the clothes they wear and the
instruments they use
most of us aren't as careful as people
in a hospital
have you ever put something like a
pencil into your mouth
that's one way germs may get into your
body
taking a bite of someone else's food is
another way you may get germs into your
body
that's why it's a good idea to refuse
offers like this
you can also get germs from another
person by drinking from a glass that
someone else has used and not washed
food that has been handled with unclean
hands yours or someone else's may have
germs on it
when you eat such foods germs can get
into your body
many germs thrive on the warmth food and
moisture found in your body
so if your skin is cut or broken germs
may enter your body and cause an
infection
to help prevent an infection you can
apply an antiseptic
which like the germ fighting elements in
some soaps kills many of the germs
but even if your skin is not cut or
broken it's still a good health habit to
care for your skin and keep it clean
let's see why
this drawing shows us a cross section of
the skin
here is one of the hairs which grow out
of the skin
the oil gland produces oil which makes
its way along the hair to the surface of
the skin
and here's a sweat gland
it produces sweat
or perspiration which is carried along
the sweat duct to the surface of your
skin
your glands give off sweat all the time
but you notice it most when you're warm
sweating helps cool your body when it
gets overheated
sweat is water which contains waste
materials from your body
when the water evaporates the waste
materials are left behind along with oil
dirt and germs
this mixture is everywhere on your skin
right down to your fingertips
let's transfer a bit of this oily
mixture to a glass slide
now let's try to get the slide clean
water alone hasn't done it
water alone won't get your skin very
clean either
what about soap and water
the soapy water gets around and under
the oil and loosens the mixture
in a similar way soap helps to get rid
of the oil that is mixed with the dirt
and germs on your skin
so when you wash you need to wash
everywhere
and with soap
your scalp also perspires
it gives off waste products as well as
bits of skin
dandruff
since there is so much hair on your
scalp much oil collects there
so you have to wash your hair and scalp
thoroughly
and often
if a soap is used that contains a
germicide
leaving it on for a minute or two will
kill more germs
using a germicidal soap helps eliminate
germs and unpleasant odors
you especially want to wash thoroughly
where you perspire heavily
giving your face a good washing is
important
you want to wash away the oily mixture
which may cause pimples
and now a good rinsing will wash away
the dirt oil wastes and germs
when you dry
it's especially important to dry between
your toes
the spaces between your toes are warm
and when they're moist microscopic fungi
can grow there such fungi cause itching
and redness and breaks in the skin which
we call athlete's foot
because germs live in the dirt under
nails having clean fingernails is
another good health habit
clean nails look nice too
brushing your teeth is a kind of washing
too
brushing removes food particles which
might otherwise be fed upon by the germs
in your mouth
such germs form acids which can attack
your teeth and cause tooth decay
dan's all dressed now
his body is clean his clothes are clean
but more than that cleanliness will mean
better help for dad
