Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

Students explore both polymers and copolymers. They use 2D and 3D models and chemical animations to do this. They investigate both addition polymerization and condensation polymerization, and then compare linear, branched, and cross-linked polymers. They connect the density of polymers with differences in their structure. Finally they connect polymer structures with their ease of destruction, and consider the importance for recycling.

Students will be able to:

  • compare linear, branched, and cross-linked polymers;
  • connect the density of polymers with differences in their structure;
  • connect polymer structures with their reversibility, and consider the importance for recycling.
