Use this expanded second edition of Polymers All Around You! to introduce elementary, middle, and high school students to polymers with exciting, hands-on activities: [ dissolve plastic in water [ make gooey gluep and slime [ create a cellophane tape kaleidoscope [ skewer a balloon (without popping it!) [ soak up water with a polymer powder [ investigate mysterious invisible crystals [ test a grocery bag's stretch [ shrink plastic into fun shapes [ and more! By bringing polymer activities into your classroom, you will help your students develop an appreciation for the products of technology that they use every day and give them a solid foundation on which to base the decisions they will make as voters and consumers.
