Polymer Science
A polymer is a substance made out of many smaller unit, called monomers. How the
monomers are put together determines the properties of the polymer. Some polymers are
stretchy (such as rubber), some are tough (such as nylon), some absorb liquids (such as
the polymers in diapers), some are man made while others occur naturally in nature.
Polymers are important substances in every day life.

Explore the holding power of diapers
Materials
Baby diapers
Newspapers or plastic containers to hold the mess
1. Try pouring some water into a diaper. See how many cups it will hold before it
leaks.
2. Tear open the diaper and pull out the material inside holding the water (it is the
polymer). Explore the polymer. Put it in a bin and let it sit overnight. What has
happened to the material? Let it sit for a few more days and see what happens.
Caution: Adult supervision is recommended.
