This is my science project

2. WHY DID I PICK THIS FOOD?
I picked this food because rice
crackers have additional
flavors to it and it might effect
the result of the science
experiment. I tried to pick
something interesting and will
be a little different to the
others because the salt and
the sauce around the cracker
might effect how much fat and
protein is in the cracker.

3. `
HOW MUCH AMOUNT DID I USE
I used a piece of a rice cracker and I smashed the
cracker into little pieces and make it look like
powder. Then I used all of the powder and inserted
the powder into the test tube.

4. How I got the result
First, I would get some test tubes.
Then I will grind the food up into
really small bits. Then I will put the
grind up rice crackers into the test
tubes Then I would put Benedict's
solution to find out if there is some
Glucose in the food. And then I put
iodine to see if there is starch in
the food.

5. Data Results
Starch is found by using iodine and pouring a
little amount of it into the test tube that has
your food in it. Before I would insert the iodine
into the test tube, I would have to insert some
water into the test tube first. Then I would put
about 2 drops of iodine into the test tube. From
the result of that experiment, I have got the
result of...
RICE CRACKERS HAVE STARCH IN
THEM

6. Does Rice crackers
contain Glucose? http:/ /

solution.jpg
Glucose is found by using benedict’s solution and some
water. I have inserted my mashed up crackers into the
test tube and inserted some water into the test tube.
Then I would have to insert benedict’s solution into the
test tube. This time, I would have to insert more than i
have for the iodine. After I have done that, I would
have to put it into a warm water bath to heat the test
tubes. Then I would wait for several minutes. Then after
a few minutes, it has turned orange. So according to the
experiment... RICE CRACKERS CONTAIN GLUCOSE

7. Does Rice Crackers Contain fat?
To see if there is fat in the Rice Crackers, I would have to take a
piece of paper and rub it onto the rice crackers. f it contains fat,
It would turn transparent and you would be able to see a dot on
the paper.
Considering to the test result,
Rice Crackers DON’T CONTAIN FAT

8. How does food change
into energy?
Food will have to be broken up into pieces
before it changes into energy. Different
types of Enzymes will digest a type of
nutrient, such as protein, fat and glucose.
One Enzyme works only for one nutrient
and will not work for anything else. So if
one Enzyme goes wrong, it will be a huge
problem. The next slide will show how the
digestive system works and how it will
work in your body.

9. The Digestive System
MOUTH= Swallows and inserts the food into your
body. The Saliva would change your foods starch
into glucose.
Stomach= The stomach would break down your food into
smaller pieces
Small Intestine= All the Rice Crackers Nutrients are extracted before going
to the vain
Liver: Removes the toxins from the Rice Cracker
Large Intestine: Parts that are considered waste is separated and
sent to the Rectum
Rectum: Waste is stored and then it will be sent down the anus
