The purpose of this experiment was to determine what type of diaper has the best absorbency, cloth or disposable.
I became interested in this idea when I found out I was going to have a little brother. We didn’t know what type of diaper we were going to use so I decided to test different types of diapers so we could have the best diaper for him.
Parents and manufactures that want the best kind of diaper for their babies may use the information gained from this experiment.
My hypothesis is that Pampers Premium will have better absorbency than other leading brands of diapers in the tests.
I base my hypothesis on a magazine called consumer Reports Issued August 1998, had an article called “Diaper Wars.” They did tests on different types of diapers, and found Pampers Premium the best of them all.
The constants in this study were:
The responding variable was how much liquid is absorbed by the diaper.
To measure the responding variable, measure water before and after diaper is soaked in a bowl. Subtract the remaining amount to calculate what was absorbed.
1. Take the first diaper, and measure the central part with a ruler drawing a square 7cm by 7cm, with the pen.
3. Take out one of the bowls, and label it with a sticky note that has the name of the diaper that will be used in that bowl.
4. Measure 500 ml of water in a graduated cylinder.
5. Pour the 500 ml. of water into the bowl.
6. Place the diaper square in the right bowl.
7. Repeat steps 1-6 for the rest of the diapers.
8. Wait 5 minutes for water to absorb into the diaper
9. Remove diaper from water but allow it to drip back into the bowl for 15 seconds. Throw the diaper piece away.
10. Pour the water in the first bowl into the graduated cylinder.
11. Measure the amount of water in the cylinder.
12. Subtract the amount of water that was in the graduated cylinder after the diaper was thrown away (step11) from 500
(The original amount.)
13. Record the amount of water that absorbed in the diaper.
14. Repeat steps 9-12 to the rest of the diapers.
15. Clean up the mess.
16. Repeat test two more times and find average.
The original purpose of this experiment was to determine what type of diaper has the best absorbency, cloth or disposable.
The result of the experiment was that the greatest
absorbency of the diapers that I tested was Pampers, having almost twice
of much of the other diaper pieces that I tested. Birdseye cloth was the
worst absorbency, having about half as much of the other diaper pieces
that I tested. Each diaper piece from absorbed almost the same amount
water in each trail.
See the graphs below
My hypothesis was that Pampers Premium would have the best absorbency of the other leading brands that I tested.
The results indicate that this hypothesis should be accepted. Pampers Premium truly had the best absorbency of the other leading brands that I tested.
Because of the results of this experiment, I wonder if Pampers would also be the driest. In other words how much moisture is "locked" inside the diaper so that it will not transfer to the outside of the diaper.
If I were to conduct this project again I would have tested more diapers and I would have sampled more of each type.
Pampers also has many types of diapers. Premium
is very soft, is extra breathability, and very good absorbency. Baby dry
helps keep babies skin dry. Rash guard releases hypoallergenic, (a protective
layer) to help babies skin.
