HISTORY of POPCORN
Popcorn was first discovered thousands of years ago byNative
Americans.It is one of the oldest forms of corn: evidence of popcorn from 3600
B.C. was found in New Mexico and even earlier evidence dating to perhaps as
early as 4700 BC was found in Peru. Some Popcorn has been found in early
1900s to be a purple color.
The English who came to America in the 16th and 17th centuries learned
about popcorn from the Native Americans.
During theGreat Depression,popcorn was comparatively cheap at 510
cents a bag and became popular. Thus, while other businesses failed, the
popcorn business thrived and became a source of income for many struggling
farmers. DuringWorld War II,sugarrationsdiminishedcandyproduction,
causing Americans to eat three times as much popcorn than they had before.
At least six localities (all in theMidwestern United States) claim to be
the "Popcorn Capital of the World":Ridgway, Illinois;Valparaiso, Indiana;Van
Buren, Indiana;Schaller, Iowa;Marion, Ohio;andNorth Loup, Nebraska.
According to theUSDA,most of thecorn used for popcorn production is
specifically planted for this purpose; most is grown inNebraska andIndiana,with increasing area inTexas.
As the result of anelementary schoolproject, popcorn became the
official state snack food ofIllinois,U.S.A.

ANSWER 2
The two cylinders will hold the different amount. Cylinder B will hold more than Cylinder
A. This is because the radius of Cylinder B is longer and this make the volume is bigger
than Cylinder A. Although the height of Cylinder B is shorter than Cylinder A, but this doesnot affect much compare the affect of different in radius.
ANSWER 3
Cylinder B is not full. There is still space in the cylinder for more popcorn.
ANSWER 4a) Yes, my prediction is correct. It is based on the formula, volume of cylinder equals to
. According to the formula, radius,r has more effect than height,hsince radius,ris
squared. Thus, the Cylinder B with greater radius,rhave the greater volume,V than
Cylinder A.
b) Cylinder B has a greater volume than Cylinder A.

d)
Different cylinders with different radii and height will have different values
in volume. Based on the formula,, the radius is squared and hence
radius plays a bigger part than the diameter. The reason why Cylinder B has
bigger volume than Cylinder A because it has a bigger radius than Cylinder A

Data and Observations:
The cylinder with have the greater radius and diameter will have the greater volume
The radius of Cylinder B is greater than Cylinder A.
The volume of Cylinder B is greater than Cylinder A.
So, Cylinder B holds more popcorn than Cylinder B.

From the tables above, it is clear that the radius lays a larger impact on the
volume of the cylinder. This is because the radius is squared in the formula, to
determine volume of the cylinder. Increasing the radius increased the volumemore than increasing the height. Therefore the radius is squared to find the
volume, which increases its impact on the volume.

CONCLUSIONContainer Height Radius Length Width Volume
CUBE 7.7460 - 7.7460 7.7460 464.76
HEMISPHERE - 6.9090 - - 690.99
CUBOID 5.00 - 10.00 10.00 500.00
CYLINDER 5.6419 5.6419 - - 564.19
CONE 10.5006 7.4252 - - 606.03
Shape of containers that give the most popcorn reflect the
maximum volume. From the activity earlier, I found that increasing the radius
increased the volume more than increasing the height. This is because the radius
is squared to find the volume, which increases its impact on the volume.
From the calculations, it has been found that HEMISPHEREcan
be filled in with the most amount popcorn. It followed by CONE, CUBOID,
and CYLINDER. These means that CUBEis the container that can be filled
with the least amount of popcorn.
Randomly, surveying at the movie theater, no CUBE or CUBOID
shapes can be found. Therefore, in this case, the HEMISPHEREwas the most
preferable container that can have the most popcorns.

i.You are the popcorn seller, what type of container would you look for?
If I was the popcorn seller, I will look for CUBE shape container. It is because
the least popcorns will be in. So, I will get the most profit for my sale.
Furthermore, it is cute and simple shape.
ii.You are the producer of the containers, what type of container would you
choose to have the most profit?
If I was the producer of the popcorns containers, I will look for CONE shape
container. It is because this shape is the easiest production and it takes less effort
and also no time consuming to produce.

REFLECTIONIn the making of this project, I have spent countless hours doing this project. I
realized that this subject is a compulsory to me. Without it, I cant fulfill my big
dreams and wishes. This project taught me to economise when selecting a
product. In this case, if we wanted the most popcorn, go for the cylinder
container However, from this project, we also learn that we must be wise in
handling manufacture of these containers to avoid wastage and harm towards
environment. We must also consider the shape of the container to bemanufactured as it affects the cost for manufacturing it. Hence, this shows that
we, as humans are gifted with minds to think and plan ahead for a better future.
I used to hate Additional Mathematics
It always make me wonder why this subject is so difficult
It always an absolute obstacle for me
Throughout day and night
Isacrificed my precious time to have fun
From
Monday, Tuesday, Wednesday, Thursday, Friday,,,
And even the weekend that I always looking forward to
From now on, I will do my best on every second that I will learn Additional
Mathematics full of effort!
