Q & A
What are bacteria and why are they important?
-Bacteria are single-celled organisms that are microscopic in size. They are important because most bacteria are beneficial, helping with digestion, immune system support, and even producing oxygen in the atmosphere.
Where can good bacteria be found in our food?
-Good bacteria can be found in various foods such as yogurt, kimchi, pickles, and soy sauce.
What are some common shapes of bacteria?
-Common shapes of bacteria include rods, spirals, and spheres.
How do some bacteria move?
-Some bacteria move by swimming in water using long tails called flagella, while others remain still or slither and slide.
What are pathogens and how do they differ from good bacteria?
-Pathogens are harmful bacteria that can cause diseases. They differ from good bacteria in that they can make a person sick, unlike the beneficial bacteria that aid in various bodily functions.
How do antibiotics and antiseptics help fight against bacteria?
-Antibiotics are medicines used to treat bacterial infections caused by bad bacteria, while antiseptics are used in cleaning products to kill bacteria and prevent infection.
What role do bacteria play in the soil?
-Bacteria in the soil act as decomposers, breaking down dead plant and animal material, and some like rhizobium help fertilize the soil.
How are viruses different from bacteria?
-Unlike bacteria, viruses are not made up of cells and cannot reproduce on their own. They require a host cell to replicate.
What is the origin of the word 'virus' and why might it be fitting?
-The word 'virus' comes from the Latin word for 'slimy liquid,' which might be fitting as it could describe how one feels when sick from a virus.
How do viruses spread and what are some common viral diseases?
-Viruses spread through person-to-person contact, food, water, air, and insect bites. Common viral diseases include influenza, the common cold, Coronavirus, mumps, measles, hepatitis, and yellow fever.
How can vaccines help prevent viral infections?
-Vaccines help prevent viral infections by using dead or weakened viruses to stimulate the body's immune system to produce antibodies, preparing it to fight off the actual virus if encountered.

bacteria and viruses for kids
today we are going to talk about two
common tiny microorganisms called
bacteria and viruses
did you know that yogurt has bacteria in
it for real but before you get super
grossed out and swear never to eat
yogurt again there is something else you
need to know all of the bacteria found
in yogurt is actually good bacteria
this kind of bacteria helps our bodies
work
good bacteria are not just found in
yogurt they are also found in other
foods like kimchi pickles and soy sauce
in fact most of the bacteria in your
body and on the planet are good bacteria
only a few kinds can make you sick and
all of those good bacteria help our
bodies and the Earth but before we talk
more about that let's talk about what
bacteria are and what they look like
what are bacteria
bacteria are single-celled organisms
that are so tiny they can only be viewed
under a microscope unlike other
single-celled organisms bacteria have no
nucleus common shapes of bacteria are
rods
Spirals and spheres some move like
swimmers in water using long tails
called flagella
some remain still
and others simply Slither or slide their
way around
here is a picture of a single bacterium
and its parts
bacteria are in your body but they can
also be found in the air on your skin in
the soil and in nature
most bacteria are not dangerous but
there are some that can make you sick
these are called pathogens some common
pathogens are food poisoning
leprosy pneumonia
strep throat and typhoid fever
some pathogens can be fought by using
antibiotics which are special kinds of
medicines used when someone becomes sick
because of bad bacteria another
substance used to fight bacteria are
antiseptics which are used in soaps and
other products used for cleaning scrapes
and cuts or simply to keep your hands
clean
now that we've talked about the bad
bacteria let's move on to the good stuff
good bacteria inside your body helps you
digest food and helps keep your immune
system strong
here's a fun fact there are just as many
bacteria cells in your body as there are
other body cells
that's incredible good bacteria can also
be found on the Earth
decomposers live in the soil and break
down dead plant and animal material
another type called rhizobium helps
fertilize soil
about 40 million bacteria can be found
in a single gram of soil wild right and
bacteria also produce about half of the
oxygen in the atmosphere
now that we know more about bacteria
let's move on to viruses
what are viruses
unlike bacteria all viruses are harmful
to the body a virus is made up of
genetic material and can infect the
cells of plants animals and other
organisms
scientists debate each other about
whether viruses are living or dead this
is because viruses do not have an
organized cell structure or nucleus and
unlike bacteria they cannot reproduce
until they attach themselves to a living
cell
a fascinating fact about viruses is the
name virus comes from the Latin word
meaning slimy liquid which if you have
ever gotten sick from one might describe
exactly how you felt while you were sick
viruses attack healthy cells and as the
healthy cells reproduce the virus also
reproduces and takes over even more
cells
when a virus invades an organism the
organism becomes sick there are many
kinds of viruses that can be passed from
person to person like handshaking
food contact
through water
and through the air this can happen when
a person sneezes or coughs because
viruses are very small and can move
through the air
insect bites bad food and animals can
also be viral sources
have you ever had influenza
which is often called the flu
what about a cold well then you've had a
virus other viruses include Coronavirus
mumps
measles
hepatitis
and yellow fever
and once you are infected with the virus
you can only treat its symptoms
even though viruses might seem scary
there are a lot of ways that you can
help prevent infection
keeping your hands washed
making sure your food is well cooked
getting plenty of sleep and eating
healthy foods will all help your immune
system defeat a virus
and if you have to go somewhere where
there are a lot of people wearing a
medical grade mask can help slow the
spread of airborne viruses just like
doctors nurses and dentists do in their
offices
vaccines like the flu shot and covid-19
vaccine can also help prevent viral
infection vaccines are often made from
Dead or weak viruses these harmless
versions of the virus trick your body
into thinking that it was the real deal
and builds up your immunity that way if
the real virus tries to infect your body
your immune system will be ready with
something called antibodies the flu shot
and other vaccines help your body to
develop these antibodies hooray for
modern medicine
now that we've learned about bacteria
and viruses Let's test our new knowledge
true or false both bacteria and viruses
do not have a nucleus
true
fill in the blank blank use weak or dead
viruses to help prevent viral infection
vaccines vaccines use weak or dead
viruses to help prevent viral infection
great job
name one of the things you can use to
fight a pathogen
antibiotic or antiseptic
true or false all bacteria are bad
faults in fact most bacteria are helpful
great job microorganism magicians
bacteria and viruses are two tiny
organisms that are all around us
sometimes called germs they can both
cause sickness
while not all bacteria are harmful all
viruses can be
so make sure you do your part and
prevent the spread of these
microorganisms by strengthening your
immune system
the next time you wash your hands wear a
mask and get enough sleep you are
helping keep your body and other people
in your community healthy and safe
