Hydrogels - 4-H Science Experiment

See how 4-H used hydrogel polymers for their national science experiment.

Steve Spangler is honored to have been chosen as the 2008 National Spokesperson for the 4-H Youth Science Day. Together with his experiment-ologists, the Spangler Science team developed this experiment just for the 2008 4-H National Science Experiment!

Water is everywhere – in the sky, in the ground, and in our homes. However, caring for this vital resource is often a challenge for each of us. Conservation means using water wisely. Protecting our groundwater is important because it is a source for drinking and irrigation. Consequently, scientists and engineers have developed amazing, superabsorbent polymers, called hydrogels, that can help.
