Are You Sure You Are Not Being Ripped Off?

Posted: July 29, 2014 in Uncategorized

Problem Statement

Are you sure you are not being ripped off from the things you buy? Well, this is an experiment to see if the products you buy contain the same amount which is placed in the label and to see if it is consistent with it packaging. The products which will be used here will be “Boy Bawang” and “My Juiz”.

Hypothesis

If you measure “Boy Bawang” and “My Juiz” six times each, then it will have the same measurement with each package and it will show the consistency in the packaging from what is shown in the cover.

These are the materials needed to conduct the experiment…

sicence lab design

  • 6 packs of Boy Bawang (30 g)
  • 6 packs of My Juiz (35 g)
  • Beaker
  • Digital scale

This is the procedure…

Boy Bawang

boy bawang tests

  1. First, get the materials needed for this experiment. (6 packs of 30 grams “Boy Bawang”, Beaker, and Digital Scale)
  2. Then place the beaker on the digital scale and press tare to make the weight back to zero.
  3. Next, open 1 pack of the “Boy Bawang” and place it in the beaker.
  4. Record the weight seen on the digital scale when the result is shown.
  5. Afterwards, repeat the process 5 more times with 5 different “Boy Bawang” packs to make a total of 6 tries.
  6. Finally, compare the results to one another to see if all the packs have the same weight to what is said on the cover.

 

My Juiz

my juiz tests

  1. First, get the materials needed for this experiment. (6 packs of 35 grams “My Juiz”, Beaker, and Digital Scale)
  2. Then place the beaker on the digital scale and press tare to make the weight back to zero.
  3. Next, open 1 pack of the “My Juiz” and place it in the beaker.
  4. Record the weight seen on the digital scale when the result is shown.
  5. Afterwards, repeat the process 5 more times with 5 different “My Juiz” packs to make a total of 6 tries.
  6. Finally, compare the results to one another to see if all the packs have the same weight to what is said on the cover.

Conclusion

  • The results show that the “Boy Bawang” was short of weight by a lot of times from the weight shown in the cover which is 30 grams. Same goes for the “My Juiz” which should have weighed 35 grams. I can conclude that with these brands, the way of their packaging is not consistent with each other, it is not following the amount shown in the cover. The other packs weighed less than the other and what is worse is that all the packs did not even reach the weight that is written on the cover. Customers are not purchasing the right amount of product declared by the producers.

Recommendations

  • When measuring products using the digital scale, one should always remember pressing tare. If the tare button is not pressed, then all the measurements of the weights of the product will be different. This was the difficulty in this experiment because I had to repeat measuring and use the extra products I had since I kept on forgetting to press tare on the digital scale.
