Make Gak: Experiment with Polymers
While most matter exists in one of four states (solid, liquid, gas, or plasma), sometimes matter can exhibit properties of more than one state. These substances, called polymers, exist in a kind of in-between state, exhibiting properties of both a liquid and a solid. In this science activity, you and your child will experiment with this in-between state of matter by creating a polymer using borax, white glue, and water. As your child enjoys the ooey-gooey fun, he'll learn an important science lesson about the states of matter.
