On Tuesday, We discussed Marion Donovan. She invented the first disposable diaper in 1951. We did an experiment to determine which disposable diaper holds the most fluid. We learned about polymers and estimated how many cups of water each diaper will hold. We learned about how disposable diapers absorb so much fluid. We figured out how much fluid a disposable diaper can absorb.We found that different brands of disposable diapers absorb different amounts of fluid.
