  1. Which Diaper Absorbs More? Caitlyn Connelly

  2. 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.

  3. Independent variable- different brands of diapers Dependent variable- amount of water absorbed

  4. 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.

  5. Hypothesis If Huggies has more polymers then it absorbs more water then Pampers.

  6. Materials • Scale • 5 Huggies diapers • 5 Pampers diapers • Syringe • Food dye and water mixture • Two bowls

  7. Procedure • First weigh the diaper and record the weight. • Using a syringe add colored water to the diaper until it can’t absorb anymore. • After the diaper reaches its maximum absorption, dispose of the extra water the diaper didn’t absorb. • Then, weigh the diaper again and record the weight. • Next, subtract the second weight from the first weight to determine how much water the diaper absorbed. • Record the difference. • Repeat steps 1-6 for nine more diapers.

  8. Weaknesses and Improvements • I could have used more types of diapers. • I could have did more trials with each type of diaper.

  9. Future Studies
