    1. 1. WHAT’S IN MY FOOD? APPLE Image Credit: http://2.bp.blogspot.com/Image credit: http://farm4.static.flickr.com/ _uqBx13aymCE/TC704swH-7I/AAAAAAAACjc/ 3224/2350015548_36c1d71a1d.jpg qG2n3U4Frvg/s1600/3458436097_2a23292044.jpg By Yuki Ueno Peters
    2. 2. WHY DID I CHOOSE THIS FOOD? I chose this food because I thought that if I were to investigate an article of food, why not look at something that I eat frequently, so the next time I eat it, I will be completely aware of what exactly I am eating?I am going to look at 1 apple. Unit: Apple(s)
    3. 3. SOURCE FOR NUTRITION INFORMATION Image credit: http:// www.bioch em.uwo.ca/ fac/yang/ coloured_te st_tubes.jpg Source for Nutrition Information:My Experiment for Starch, Glucose, Protein, and Fat
    4. 4. STARCH TEST RESULTS Observation: The sample maintained its normal state wheniodine was poured over it, therefore not containing any starch.Procedure: In order to test foods for starch, you will first need the article of food youwould like to test, as well as a supply of iodine. You will then have to fill an eyedropper withthe iodine, and with the food on some sort of plate or tray, drop a few drops on it. Makesure to not under-do or overdo the iodine, because this can heavily affect your results. If thesample turns black, that is a sign of starch in whatever food you chose to examine. Comparing the results from my experiment and research... I found that both sources tell us that apples have almost no protein at all. The apple did not turn black therefore... Present or Not Present: Not Present Image Credit: http:// www.jcrows.com/Iodine iodine_1oz_lg.jpg
    5. 5. Image Credit: http:// upload.wikimedia.org/wikipedia/commons/6/6a/ GLUCOSE TEST RESULTS Sugar_cubes.jpg Observation: I noticed a change of color in the Benedict’s Solution as it transformed somewhere in between brick-red and yellow. Comparing the results from my experiment and research... I found that both sources tell us that apple contain a lot of glucose. The apple did turn brick-red and yellow therefore... Present or Not Present: Present Procedure:
When
testing
foods
for
glucose,
you
will
need
a
test
tube,
the
article
of
food
you
wish
to
 test,
and
this
time
instead
of
iodine,
a
liquid
called
Benedict’s
Solution
will
be
used.
What
will
be
 done
>irst
in
this
process
is
the
mixing
of
food
and
distilled
water,
which
will
be
followed
by
 carefully
pouring
the
product
into
an
eyedropper.
You
will
then
add
40
drops
of
the
mix
into
the
 test
tube
that
you
prepared
earlier.
Finally,
add
10
drops
of
Benedict’s
Solution,
and
heat
the
test
 tube
that
you
prepared
earlier
to
around
40‐50
degrees
celcius.
If
you
notice
any
change
of
color
in
 the
liquid
(green,
yellow,
or
brick‐red),
it
is
a
sign
of
glucose
in
whatever
food
you
are
examining.
    6. 6. PROTEIN TEST RESULTS Observation: I did not notice a change of color in the Biuret Reagent. Comparing the results from my experiment and Biuret Reagent research... I found that both sources tell us that apples have almost no protein at all. Image Credit: http:// secure.sciencecomp any.com/Assets/ images/nc2083n.jpg The Biuret Reagent did not turn purple therefore... Present or Not Present: Not PresentProcedure:
The
test
that
will
show
whether
or
not
the
food
that
we
are
examining
contains
 protein
is
called,
the
Biuret
test.
In
order
to
preform
this
test,
>irst
you
will
need
to
add
a
few
drops
of
Biuret
reagent
to
your
sample.
Then,
put
the
test
tube
in
hot
water,
and
if
you
 notice
a
change
in
color
(purple),
protein
is
present
in
the
sample
that
you
are
testing.
    7. 7. FAT TEST RESULTS Observation: The piece of paper did not turn translucent.Image Credit: http://www.longislandpress.com/wp-content/uploads/ Comparing the results from my experiment and2010/09/36GreenPage.jpg research... I found that both sources tell us that apples don’t contain fat. The piece of paper did not turn translucent therefore... Present or Not Present: Not Present Procedure: Smudge the sample on a piece of paper, and see if it becomes translucent. If it does, it contains fat.
    8. 8. WHAT HAPPENS TO THE APPLE INEACH PART OF THE DIGESTIVE SYSTEM? Mouth: Chews the apple into tiny pieces, to make the work easier for the stomach. Esophagus: The esophagus takes the apple to the stomach. Stomach: The apple is further broken down by acids (chemical and enzymatic digestion), slowing making its way into the small intestine. Small Intestine: All of the apple’s nutrients are extracted beforeImage Credit: http://brookingsapbiology.wikispaces.com/file/view/ human_digestive_system.jpg/212015132/ releasing them into the veins. human_digestive_system.jpg Liver: The liver removes toxins from the apple and Rectum: The waste is stored in the produces bile.rectum until it is time to get rid of it. Pancreas: The pancreas makes and delivers digestive juices. Anus: The anus is where the waste Large Intestine: The parts of the food that are leaves your body/digestive system. impossible to digest are moved along the large intestine, which sends it to the rectum.
    9. 9. WHAT ENZYMES ACT ON THE FOOD, WHAT DO THEY DO TO THE FOOD AND WHY? Apple Image Credit: http:// www.thefatlossauthority. com/fat_loss_tips/wp- content/uploads/ 2011/02/calories-in-an- apple.jpgEnzymes (such as enzymes in the stomach, and small intestine) speed up the process of breaking down food. Without enzymes, this task would take a very long time.
    10. 10. WHERE THE FOOD GETS ABSORBED INTO THE BLOOD STREAM Small Intestine Image Credit: http:// www.daviddarling.info/images/ small_intestine.jpg Small Intestine: All of the apple’s nutrients are extracted before releasing them into the veins.
    11. 11. WHICH PARTS OF YOUR BODY WILL USE THE FOOD AND WHAT FOR? Apple Nutrient: Glucose Image Credit: http:// www.thefatlossauthority.com/ fat_loss_tips/wp-content/ uploads/2011/02/calories-in-an- apple.jpg Blood - The apple’s nutrients are released into the bloodstream, where they will be moved throughout the body. This is done in order to maintain a healthy body. Out the anus - Some of the food is turned into waste, where itleaves the digestive system/body through the rectum, out the anus.
