PROJECT TITLE
Do drink companies give as much as they say they are?
INTRODUCTION
Over the years, A few consumers have been complaining about the amount of liquid seen present in drink boxes from the different drink companies and are wondering if they are getting their money’s worth. The purpose of this project is to investigate if the amount of liquid serving displayed on the drink boxes matches the amount that is present.
The objectives that will be made are:
- Measuring the volume in each carton
- Comparing the different volume
- Measuring the mass of each product
METHOD OF COLLECTING DATA
The researcher will be using four (4) different brand juices (Freshhh, Big-jo, Squeez, and Juciful). The volume of each liquid will be measured in a measuring jug a data collection sheet will be made to obtain the measurement of each product. To find the mass a calculation of each product will be performed with the use of a calculator. Mass is measured in Kilograms (Kg) so to find the mass each product will be weighed with the use of a scale and the pounds will be converted to kilograms (kg).
Data Collection Sheet
Name of band juices | Net Content (ml)Measurements | Actual Volume (ml)Measurements | Mass Measurements |
PRESENTATION OF DATA
The Table below shows the measurements and mass measurement of each drink from the different drink companies:
Name of band juices | Net Content (ml) Measurements | Actual Measurements (ml) | Mass Measurements (kg^{2}) |
Big-JO(Orange Strawberry Banana Drink) | 450ml | 450ml | 229,500kg^{2} |
Juciful(Pineapple Drink) | 450ml | 400ml | 2,040kg ^{2} |
Squeezz (Lemon Lime Drink) | 450ml | 400ml | 2,040kg ^{2} |
Freshhh(Guava Pineapple Drink) | 450ml | 375ml | 170,250 kg^{2} |
The graph below shows the comparison of volume:
ANALYSIS OF DATA
The Formula for finding mass:
* Mass =Volume x Density
Formula for converting pound to kg:
1 lb =0.453592kg
- Squeezz (Lemon Lime Drink)
1.12lb X 0.454kg = 0.51kg (Pound to Kilogram)
400ml X 0.51kg
^{Note:} (We would have to convert the 400ml to kg and 1ml = 1000kg
400ml X 1000kg = 4000kg)
4000 kg X 0.51 kg =2,040 kg^{2}
- Big JO ( Orange Strawberry Banana)
1.12lb X 0.454 kg = 0.51kg
450ml X 0.51kg
(450ml X 1000kg =450,000kg)
450,000kg X 0.51 kg = 229,500kg^{2}
- Juciful ( Pineapple Drink )
1.12lb X 0.454 kg = 0.51kg
400ml X 0.51kg
(400ml X 1000kg = 4000kg)
4000 kg X 0.51 kg =2,040 kg^{2}
- Freshhh (Guava Pineapple Juice )
1lb X 0.454 kg = 0.454kg
375ml X 0.454kg
(375 ml X 1000kg = 375,000kg)
375,000 kg X 0.454kg =170,250 kg
DISCUSSION
After collecting enough information, I was a bit disappointed with the result. All the other drink companies except Big-JO (Orange Strawberry Banana Drink) calculated volume had less than the stated volume. This just proves that most drink companies are not being truthful about the amount they are producing. A comparison between Juciful (Pineapple Drink) and Squeezz (Lemon Lime Drink) both showed similarity in volume measurements which made the mass measurements the same.
Freshhh (Guava Pineapple Drink) had the least amount in volume and mass while the others had under 450ml.
CONCLUSION
It has been concluded that manufacturers that produce these juice boxes are not taking into consideration that accurate measurements are a necessity for most consumers or else they wouldn’t be purchasing any juice boxes if they are not getting what they are paying for. This could lead to them suing a company for giving incorrect information.
