  1. PPCD/PALS Science Project • Problem: Which hold more liquids? A Diaper or a Pull-Up?

  2. HYPOTHESIS Using three Luvs diapers and three non brand name pull ups. We will add three different types of liquids to each one; which would hold more liquid? The class guessed that the Luvs diapers will hold the most liquid.

  3. Classroom selection *Denotes Non Verbal Students: student selections made by pointing after given a choice

  4. Variables • Independent Variable- Three types of diaper and three types of pull-ups (e.g. Luvs diapers and non brand name pull-ups.) • Dependent Variable-Three types of liquid: milk, grape kool aid, and class made waste material (milk, Cracker Barrel syrup, and Jif peanut butter)

  5. Materials • Three Luvs diapers • Three non brand pull-ups • ¼ cup of Milk • ¼ cup of Kool Aid • ¼ cup mixture of syrup, milk, Jif peanut butter, Cracker Barrel syrup

  6. Procedure • We pour ¼ cup of each liquid variable per cup • We mixed the Cracker Barrel syrup, milk, and peanut butter for our class made waste • We placed items on the table: three Luvs diapers three non brand pull-ups and labeled each of them accordingly • Students poured each liquid variable onto the diapers/and into the non brand pull-ups • We check our classroom selection chart to see which held more liquid

  7. Results • The Luvs diapers held the most liquid. This proves that our hypothesis was correct.

  8. Conclusion • We selected the Luvs diaper as the best choice for holding liquid, as it held more liquid. • We believe the class made waste was not as absorbent as the other liquids. Therefore, we did not see a significant change in either the diaper or the pull-up, concerning the absorbency of a thicker substance.
