Problem/question: Which fabric- cotton, nylon, or polyester can retain the most water?
Hypothesis: If we soak cotton, nylon, and polyester fabric then we predict that polyester fabric will retain the most water.
*Cotton is soft and used to make clothes *Polyester is wrinkle free *Nylon is rough and is cut in planes
Independent: We changed the type of fabric. Types we changed, cotton, polyester, and nylon. Dependent variable: Our dependent variable was how much water each fabric retained. Constants: The type of liquid, and the type of beaker.
Teacher: 3 glass 100mL beakers Austin: cotton 100% Chase: Polyester 100%, Nylon 100% in square tile if possible
1. Acquire 3 glass 100mL beakers. 2. Fill one glass 100mL beaker to approximately 75mL of water 3. Dunk cotton slowly in water for precisely 5 seconds 4. Slowly pull out the dunked cotton and hold in air with tongs until every last drip of water has dripped in to the beaker 5. To see how much cotton has retained you must subtract the new amount of water from the original amount of water (75mL). Record data in the data table 6. Repeat steps 1-5 two times for a total of 3 trials. 7. Repeat steps 1-6 for polyester 8. Repeat steps 1-6 for nylon

From the background information we know inferred that if we soak cotton, nylon, or polyester fabrics then we predict that polyester will retain the most water. Our hypothesis was correct since out of the 3 fabrics we ran trials on to see which one could retain the most water. Polyester retained an average of 71.3 Ml of water compared to cotton which retained an average of 64.3 and nylon which retained an average of 68.3 Ml of water. Our data shows that cotton retained 63mL of water the first trial 65mL the second &65mL the third which lead up to an average of 64.3mL of water retained. Polyester retained 70mL of water the first trial 72mL of water the second time and 72mL of water the third time which lead up to an average of 71.3mL retained. Nylon retained 65mL of water the first trial 70mL the second and 70mL the third which adds up to an average of 68.3mL of water retained. From this info we can say polyester retained the most water. The reason polyester retained the most water is because it’s more thick and dense so it could hold and retain the water. Cotton and nylon did not retain as much water because they were light and had lots of holes which allowed the water to travel through. A new question that arose from this experiment is what if we used a different liquid such as soda and tried to see which fabric retained the most. The reason we thought of this is because soda is denser than water so we might get different results.
