Diapers have always been a beautiful mystery to me…how CAN they hold so much? I thought it would be fun to do a little science experiment with the boys to see if we could get to the bottom {get it?} of this mystery.

absorption experimentAbsorption Experiment

This is a really fun and versatile experiment because it could incorporate all sorts of math depending on the level of the child’s math skills. measuring cup for absorption experimentYou could have the child use the mL side of the cup, if subtraction is desired or make it more complicated by using the cup measurement side for manipulation of fractions.   If you have a pre-formal-math level child, this is still a lot of fun by just guessing what is going to happen. I had the kids cut three samples of materials into same size squares. absorption materialsWe used a washcloth, a diaper and a paper towel. We noted what the water level was and then dipped the first material into the water. material goes into waterUsing tongs, we then moved the soggy material to another location and noted the AFTER measurement. We repeated this with the paper towel and then the diaper. The diaper reacted much differently than the other two materials. absorption diaper snowI scooped out the diaper covering and what was left was diaper snow! As we watched, more and more of the water was absorbed. diaper strainingI wanted to isolate the left-over water for our experiment so we strained the diaper snow to see how much water remained. absorption finalWe definitely had a winner!   There was only a few drops of water. At this point, there are several things you could do with the experiment results:
  • Find the amount of water absorbed by each material.
  • Chart and graph the results.
  • Find the differences between each material.
  • Estimate what amount would be absorbed if the size of the material was smaller.   Or larger.
  • Find another material and guess where in the absorption spectrum it would lie.
  • Play with the diaper snow.
The diapers we used for this activity was Seventh Generation.   Seventh Generation has Overnight Diapers, Free & Clear Diapers and Free and Clear Training Pants that are all free of chlorine processing, free of fragrances and latex, free of petroleum-based lotions, and hypoallergenic.   You can see from our experiment {and with a trial on your diaper-wearing child} that they have premium absorbency!
