Which Diaper Absorbs More? Caitlyn Connelly
Research A polymer is many molecules strung to make long chains. Polymers enhance absorbency. There are two types of polymers in Pampers diapers. They are polyethylene and polypropylene. Huggies contains the polymers: polyacrylate, polypropylene, polyester, and polyethylene. Absorb means to suck up.
Independent variable- different brands of diapers Dependent variable- amount of water absorbed
Purpose The purpose of this experiment was to determine which diaper absorbs more water. I wanted to know this because my aunt is pregnant and I wanted to help her out by knowing which diaper absorbs more.
Hypothesis If Huggies has more polymers then it absorbs more water then Pampers.
Materials Scale 5 Huggies diapers 5 Pampers diapers Syringe Food dye and water mixture Two bowls
Procedure 1.First weigh the diaper and record the weight. 2.Using a syringe add colored water to the diaper until it can’t absorb anymore. 3.After the diaper reaches its maximum absorption, dispose of the extra water the diaper didn’t absorb. 4.Then, weigh the diaper again and record the weight. 5.Next, subtract the second weight from the first weight to determine how much water the diaper absorbed. 6.Record the difference. 7.Repeat steps 1-6 for nine more diapers.
Weaknesses and Improvements I could have used more types of diapers. I could have did more trials with each type of diaper.
