Science Performance Task

Posted on: July 23, 2013

There are a lot of people who buy and consume Jack n’ Jill products in the Philippines due to their wide variety of products. Their products range from candies, biscuits, chips and etc. But what if the consumers weren’t getting what they paid for? What if the amount of product that they are getting is actually different from the amount declared by the company. This means that all of the consumers buying Jack n’ Jill products aren’t getting their money’s worth.

Because of this problem, I have decided to conduct an investigation to check whether or not Jack n’ Jill are actually giving the amount of product to the consumers that they declared. The initial hypothesis was that the producer was not giving the amount of product that they declared and people were not getting their money’s worth. To test this, I chose two products of Jack n’ Jill (Cream – O cookies and XO candy) to test. For the cookies, the declared weight was 36 grams. Using an electronic scale, I measured the weight of the cookies in 3 separate trials. I did the same procedure also for the measuring of the candy with a declared weight of 3.5 grams. After measuring, the 3 weights that I was able to record were 37 ± 0.5 grams, 36 ± 0.5 grams and 37 ± 0.5 grams. The candies that were measured weighed at 4 ± o.5 grams, 3 ± 0.5 grams and 4 ± 0.5 grams.

Based on the results of the experiment, it can be said that the buyers of Jack n’ Jill products, Cream – O and XO at least, are getting what they paid for since the measured weight from the 3 trials are close to the declared weight of the product. It can be concluded that Jack n’ Jill actually give the amount of product they declare to the consumers.

A possible recommendation for this investigation is to probably have different ways of measuring the weight of the product to confirm the validity of the experiment. Since the instrument used only measured to the nearest ones digit, it would not be as accurate if other instruments were used to measure the weight. It also would have been better if there were more trials to thoroughly check if the producers were actually giving the amount of product that they were declaring.
