    • Operation Saggy, Baggy Diapers Standard Indicator Activity April Scott November 2, 2009

    • What’s the Problem?
      • Ms. Scott’s sister is getting ready to have a baby and she wants to know which diaper brand is the best to use. She wants a diaper that will work best for her family (cost, durability, absorbency, etc.).
    • Important Terms
      • Absorb: to take in, suck, or swallow up
      • Durable: able to last a long time
      • Biodegradable: capable of being broken down especially into harmless products by the action of living things
      • Procedure: a series of steps followed in a regular definite order
      • Generic: not protected by a trademark registration
    • Materials Needed
      • 4 different brands of diapers, labeled #1, #2, #3, and #4 in their packages with the price
      • Paper to record data
      • Pencil
      • 4 plastic containers
      • 250 mL measuring beaker
      • 100 mL graduated cylinder
      • Paper towels
      • “ Consumer Product Testing” sheet
    • Brand Names of Diapers for Experiment
    • Brainstorm
      • Look at the labeled diapers and brainstorm characteristics that make a good diaper. Write these down.
      • What should the diaper have to stay attached?
      • How thick should the bottom be?
      • How would you choose which brand of diaper is the best?
      • How could you test the absorbency, durability, and biodegradability of the diapers?
    • Procedure
      • Today, you are going to test the absorbency of 4 different brands of diapers. Write out your procedure for testing the diapers. (Remember, you are scientists and need to make careful observations and measurements!)
      • How will you measure the water?
      • How much water will you use at a time?
    • Procedure (cont.)
      • Make a prediction of which diaper be the most absorbent. Write this down as your hypothesis.
      • Begin to test your hypothesis and record your data using the “Consumer Product Testing” sheet.
      • Use the price per package and the amount of diapers in the package to determine the cost of 1 diaper in the package.
    • Record Results
    • Conclusion
      • Review your findings. Which diaper is going to be the best for Ms. Scott’s sister to use considering cost, appearance, and absorbency?
      • Which diaper held the most water? (absorbency and durability)
      • Which diaper was the cheapest? (cost)
      • Were there trade-offs in making your decision?
      • Did your results match your hypothesis?
    • Further Questioning
      • How could you apply this type of testing to other products?
      • How did you decide which diaper was the best choice?
      • How would additional features of the diaper affect the consumers desire to purchase the product?
      • Why was it necessary to measure the water amounts carefully when carrying out the procedure?
