Science: Water Absorbing Polymers
These sites introduce students to water absorbing polymers. Learn how they work, what substances they absorb, how much liquid can be absorbed, and how they are relevant in our daily lives. Includes experiments, videos and resources for obtaining the materials needed for completing these experiments in the classroom.
Explore the history of superabsorbent polymers, how it is currently being made, and its uses. NOTE: This text may be too advanced for younger students, but background information for teachers.
Disappearing Milk: Activity/Video
Watch as a magician pours milk into an apparently empty glass. When he turns the glass upside dow, nothing pours out. He uses a super absorbent polymer to pull off his trick.
