Check out Macrogalleria, where you can learn all kinds of nifty stuff about polymers and polymer science!
A sustainable polymer is a plastic material that addresses the needs of consumers without damaging our environment, health, and economy. The feedstocks for sustainable plastics are renewable, such as plants. The production of sustainable polymers should use less net water and non-renewable energy, emit less greenhouse gases and have a smaller carbon-footprint than their non-sustainable counterparts, while still being economically viable.
Because everything that we see and use every day is made up of natural or synthetic (man-made) polymers, it’s important to know how they are created, how they can be used, and how they affect our lives. By understanding polymers, you may even think of a new way of making one, a new type of one, or a new way of using one already created to better the lives of those you know and care about.
10B1 give us the lowdown on how different additives affect the properties of polymers. They model the process by playing monomers.
10 Polymer-based Products You Use Every Day
Steve Spangler shares an easy science demonstration to learn the differences between Styrofoam and the more eco-friendly starch-based packaging material.
Is it a solid? Is it a liquid? Just what is this slimy, stringy, rubbery stuff? This variation on slime will probably remind you of a similar substance found in many toy stores. This is the most popular version of "slime" among teachers because it's so easy to make and serves as a great visual tool for introducing students to the properties of polymers.

For our purposes, slime will be defined as any non-Newtonian fluid. If this term sounds hopelessly technical, please read on here.
