Station #1: How old are you?
1. A Julian year is defined as 365 days of 86,400 seconds each which total unit 31,557,600 seconds.
A Draconitic year depends on how long it takes the sun to complete one revolution with respect
to the lunar node, which is known as a eclipse; this happens when the sun and moon intersect
2. Julian and Draconitic years are both associated with astronomy and other sciences. They are both
used to tell the duration of time as unit. The Julian year is the distance covered by a light year
while the Draconitic year is used to tell the lunar node, which is the time, needed for an eclipse to
3. Yes, the age differs in each category because it depends what time unit each category is used for.
It may have to do with the solar system and the rotation of the sun. Some planets have very long
or very short days because it depends on how long it takes for that certain planet to rotate around
4. I do not think that these age differences will affect our health because our body is the same and it
doesn’t change depending on what time frame we are using. Our body does not change if we
travel to differ places in the world or if we follow different calendars therefore, the age of our
body remains consistent. Our birthday may differ because it depends what time frame that certain
calendar or planet is using but our body is the same.
Station #2: How good is your hearing?
1. My hearing ranges are different in each ear and there many factors of why this is so. Firstly, it
depends how the sound waves go into the ear and hit the tympanic membrane. It is varied because
it depends how strong the waves are causing the inner bones to move and amplify the sound.
2. My hearing is approximately 16k and the average hearing is around 16,000 to 20,000 vibrations
per second which implies that my hearing is average and not the best.
3. There are many activities that cause damage to our hearing. Firstly, when we listen to music with
headphones on maximum it damages our ear drum because the tympanic membrane slowly
becomes weaker as the sound becomes aggressive. If you constantly listen to loud music your
eardrum will eventually burst causing permanent damage. You can keep your range normal by
not constantly listening to maximized volume music and making sure to clean out your ears from
the bacteria and dust that accumulates.
4. Some biological damages to the ear are blocked ear canals which can be due to the accumulation
of ear wax and this can cause a lack of hearing since it is blocking the acoustic meatus.
Station 3a: How far can you see?
1. My eye sight scores are not the same for each eye and there could be many factors of why they
could be different. It may depend on the structure of each eye and how delicate there parts are.
The strength of each eye may be related to the cornea and how much light is reflected and passes
through to the retina. It depends on how much strain and stress an individual’s eyes can take and
which eye is mostly used to focus in on an object.
2. I think my eyes are better than an average human because at one point in my life I had to wear
glasses and as years went on my eyes improved. My eyes has gotten better whereas, many other
people wear glasses and their eye sight may not improve.
3. Some activities that affect the gain or loss of our vision are ones that are associated with
excessive light. Some activities that harm our vision are watching too much TV, excessive use of
the computer and video games. The successive use of light can damage our eyes and put stress on
our cornea. Also, staring at something for a long period of time can cause strain to one’s eyes.
Activities that do not harm our vision are activities that do not require constant light.
4. Some biological factors that can affect eyes are if someone in your family has any eye diseases
such as, cataracts. This causes blurred vision which can be repaired but it may be passed down to
other members of the family. Being exposed to frequent bright light can also damage the lens
which follows to the retina as this can cause severe damage to an individual’s eye sight.
Station 3b: How far can you blow?
1. You would want to know your blowing distance because it can give you an idea of how much
capacity your lungs are able to produce. If you are able to blow far you will know that your lungs
are able to hold large amounts of air and be able to release it in a heavy quantity as well. It tells
you how strong your lungs are and how strong they are.
2. There is a variation between my group members because everyone has a different body with
variations of strength in every organ. Everyone’s lungs may have a different vital capacity and
they may not be able to hold that much air to be able to blow out a candle at 90 or 100 cm.
3. The lungs adapt to certain conditions depending on how much oxygen is present at each location.
It depends on how much air we need to take in to be able to breathe efficiently. For example, at
sea level there is enough oxygen and we will be able to breathe at a normal pace whereas, at the
mountain tops there is a lack of sufficient oxygen so it will cause us to breathe heavier and more
frequently because of the insufficient supply of oxygen which we need to survive.
4. The disadvantages of changing altitudes is that each altitude has a different amount of oxygen
present. If you are at a high altitude, there is not enough oxygen in the air so you may not be able
to breath as well. Your lungs will feel heavy and breathless since they are unable to inhale enough
oxygen. If you keep changing altitudes, your lungs will not be able to adapt to the conditions fast
enough and that may cause harm to your health.
Station #4: How big are your lungs?
1. There are many factors that can influence lung capacity. There are biological factors such as, not
having a large rib cage which means that your lungs will not be able to expand as much. Factors
such as, height and weight can also vary your lung capacity because it depends how healthy you
are to be able to take in a certain amount of air. The accumulation of tar and chemical irritants can
also vary your lung capacity because the tar starts to build up in your airways and limits the flow
2. There are many ways to change your lung capacity. You can do various exercises such as,
stretching and taking in deep breathes which will strengthen your diaphragm. You can also play a
wind instrument, which will control your breathing and help you use all your alveoli. You can
decrease the lung capacity by smoking and inhaling irritants which will limit the flow of air.
3. It is important to do multiple trials as shown in the chart above because you may not get an
accurate result the first time. It could depend on how strong you are the first time and it might
make you weaker in the other attempts. This is why it is best to wait a bit after each trial so you
can get the most accurate results possible.
4. The results obtained from this activity may not be 100% accurate because you aren’t able to tell
your complete lung capacity by blowing up balloons. You will have to do several trails and use
machines to accurately predict your capacity. Measuring balloons may not be able to tell your
capacity because it is not measuring your actual lungs.
Station #5: How hard does your heart work?
1. My heart pulse scores are different in each category because it depends on how hard your heart is
working. This is because when your muscles are used excessively they need to be replenished
with oxygen and the only way to receive oxygen is for the blood to flow faster. If you are in
stable position for example, sitting, your body does not need as much oxygen because your heart
is not working as hard for the blood to flow faster. Pulses depend on how fast your body needs to
be replenished with oxygen.
2. Pulse 30 Seconds: Running, Laying down, Sitting, Standing
Pulse 60 Seconds: Running, Laying down, Standing, Sitting
Blood Pressure: Running, Standing, Sitting, Laying down
I am surprised that the blood pressure and pulses are not the same. I would expect that the blood
pressure impacts the pulses because that is how fast your heart is working. It may be varied
because it depends on how strong the heartbeat is and at what rate the heart it producing blood.
3. My blood pressure is not as bad and it is fared well for my gender and age. My average blood
pressure is 120/93 and the normal blood pressure is 120/80 which is not that far from my blood
pressure rates. This indicates that my blood pressure is normal and it is fared well for my age and
4. Some factors that lead to a healthy heart are a healthy diet and exercise. These activities will
prevent clogging of the arteries and lead to smooth distribution of the blood. Fatty foods will
increase ones cholesterol and lead to plaque that will consume your arteries and efficient blood
flow will be limited.
