A reflex action is an automatic action that our body makes without us even having to think about it.
A reflex action is a survival technique that humans have.
Coughing when something gets caught in your throat is a reflex action.
Jumping when you get a is a reflex action
Moving quickly away from something that’s causing you pain, like when you back into a prickle bush and then
you jump front is another reflex action.
Blinking when something moves quickly towards your face is a reflex action too.
The pupils in our eyes close and widen in a reflex action allowing only enough light into our eyes for us to see
things clearly. The darker it is the wider our pupils grow.
Most of our reflexes have been developed over hundreds of thousands of years.
Reflex actions are often a response to something that could hurt us - that’s why we move so quickly.
When we’re reacting to pain the part of our body that’s feeling the pain sends a message straight to the part of
our body that will move us away from that pain quickly bypassing our brain.
An action that we decide to make like to pick up a book and read or bite into an apple is called a voluntary
action.
There are other movements that our body does all the time without us thinking about it like breathing and our
heart working. These are called involuntary actions.
In our group (group 5) there are 2 females and there are 2
males. We wanted to find out which gender has good reflexes
skills. Sowandia and Shazina thought it was females because
girls have smarter reflexes cause most girls get good grades.
Sukhijinder and Nathaniel thought it was male because boys
are much more energetic. That was our opinions. We asked
some kids to vote in our class. The results were
Females-15
Males-10
We will see if its right.
The way we will decide which gender has faster reflexes is by
testing it. In our class we will take nine boys and nine girls. We ill
take a ruler and we will set the person standing straight up and
then we will instruct that person it put his hand out in mid-air and
we will then drop a ruler and when the person catches it we will
count how many centimeters he/she caught the ruler at. The we
will record data. This will tell who has faster reflexes. We will
then average out the boys score and girls score and then ssates
which gender has faster reflexes.

Start with either girls or boys.
Place them in a position where they are standing up.
Their hand should be in midair, in a position where they could catch the ruler when it
falls.
When you are positioning the ruler above the hand to be dropped, place it 6 inches above
the hand. Make sure that it is exactly 6 inches with a ruler.
The ruler should be vertical and the 0 centimeter should be facing downward while the
30th cm should be facing upward.
Let the ruler go in surprise so the person cannot guess the exact time the ruler will fall.
Vary the timing with 5 seconds.
When the person catches the ruler look at what centimeter the index finger’s knuckle is
on.
Record it on the chart.
Repeat steps 2-8 for the other gender.
Repeat steps 2-8 two more times for both genders.
Average the results for the female and male
If the average for any of the genders is between 0 and 10 centimeters, it will mean that,
that gender has very fast reflexes.
if the average of one of the genders is between 11 centimeters and 20 centimeters it
means that, that gender has a normal reflex. They are not very quick or very slow.
If the average of a gender is between 21 and 30 centimeters it means that, that gender
has a very slow reflex.
Whichever gender has a lower average is the gender with faster reflexes!

Our group has observed many things we conclude that Jackie
and Sukhjinder had the faster reflexes and the person who got
the second most faster reflexes was Rupinder and Faysal. But
from looking at all the data we state that boys have faster
reflexes skill from girls. We are not saying the girls don’t have
good reflexes skill. Sometimes girls have faster reflexes.
Independent Variable-The independent variable is the gender
Dependent Variable- The dependent Variable was the reflexes
speed in the gender.

A reflex or a reflex action is a natural control system that joins muscles that are annoyed
to response to the event occurring that is annoying it. A reflex can be built in or learned.
For example babies have reflexes that they do not know at first. As they grow up they
learn from examples. While a baby walks and it falls down they get hurt. Next time they
will be aware to keep their balance. They is how children slowly develop their reflexes and
learn how to. Soon it just comes without thinking before the brain even sends the message
to your body functions. The spinal senses the sensory stimulus which senses trouble and
sends a signal to a muscle to create an immediate action. For example if some one is in a
fire the persons reflexes will immediately start to work as soon as he/she will see the fire, feel
heat, or cannot breathe from the smoke. The ability not to breathe will go to your spinal
cord telling your muscles to start moving. As the pain get worse the brain will act more
quickly with more information to get your reflexes to be active.
Since the reflex does not signal the brain first but you muscles or reflexes this is called a
reflex arc. A reflex arc starts with excited receptors. Most reflexes go completely unnoticed
because they don’t involve a movement that can be seen. Some body functions for example
digestion, blood pressure, are regulate by reflexes. They are called autonomic reflexes.
There are many types of reflexes. Your born with reflexes. Babies have reflexes and adults. But they have
different reflexes. One reflexes that everyone has is the sneezing and blinking reflexes. You are born with
those reflexes. Lets start off with the babies reflexes. As a newborn and young infant, most of your baby's
growth and physical reactions will be determined by primitive reflexes. For example, if you brush your
newborn's cheek, he will likely turns his head that reflex is called the rooting reflex, which helps him to find a
breast or bottle for a feeding. Or if you place a pacifier in his mouth , as it touches the roof of his mouth, it
will cause him to begin sucking .Sucking reflex is when something is put in its mouth an d then its starts to
suck on it. . Another reflex would be the Moro reflex . Also called the startle reflex, the moro is usually
triggered if your baby is startled by a loud noise or if his head falls backward or quickly changes position.
Your baby's response to the moro will include spreading his arms and legs out widely and extending his
neck. He will then quickly bring his arms back together and cry. The moro reflex is usually present at birth
and disappears by 3-6 months.
