Plastic is present in nearly every aspect of our lives that we probably
take its importance for granted. Plastic is a basic component of cars,
houses, cell phones, clothing and computers, to name just a small
handful of its applications. In this experiment, students design and
synthesize their own plastics from a simple, one-pot, three-component

experimental design and materials chemistry. The plastic can be shaped or colored to suit individual student preference and students can experiment with the reaction parameters to adjust color, hardness and flexibility. Includes reproducible student handouts, Teacher Notes, and all necessary chemicals.
Complete for 30 students working in pairs.

Sodium polyacrylate, the superabsorbent polymer found in disposable
diapers, absorbs immense amounts of water. Did you know that it will also
remove metal cations from solution? The cross-linked polymer contains a
large number of sodium ions. When it is placed in a solution containing other
metal ions, they preferentially bind to anionic sites in the polymer, displacing

the sodium ions and resulting in the formation of new colored metal poly-
polyacrylate by testing the ability of the polymers to decolorize solutions of copper and iron ions. Then students will determine the exchange capacity of the polymer by measuring the amount of copper removed from a standard solution of copper(II) ions using colorimetric analysis.
Complete for 30 students working in pairs. Requires a spectropho- tometer or colorimeter. STEM

Lancaster Country Day School, Lancaster, PA
Integrated
STEM Integrated
The Gluep Production Lab is a real-life, open-ended, discovery activity with an element of corporate competition. Student research teams are challenged to use the scientific method to improve a polymer recipe and make a bouncier Gluep ball—all while staying on a fixed budget. Students design and conduct their own mini-research project as they try to win the contract to manufacture Gluep. A fantastic opportunity for students to learn about the scientific method and polymers while having fun at the same time! Includes Instructor’s Notes, reproducible student handouts, and all necessary equipment and chemicals.
Complete for 30 students working in pairs. Includes Flinn Exclusive STEM Integration Guide.
