Polymers Teacher Resources
Find teacher approved Polymers educational resource ideas and activities
Seventh graders investigate the concept of polymers. They discover unique properties and how polymers are natural. The lesson contains sufficient background information for the teacher. Students examine different types of materials and complete a KWL chart during the experiment.
This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this instructional activity with experienced chemistry learners as they will synthesize polystyrene several times and calculate efflux time and viscosity. Ideally you would use this when teaching your class about polymerization.
First, young chemists practice polymer identification by density and flame tests. With the data collected, they propose a method of separating polyethylene from other plastics and determine what property makes it desirable for recycling. This laboratory activity is ideal when covering polymers in your general chemistry class.
