Green Chemistry for In-service Science 2 Teachers

Objective Students should be able to differentiate between dif- 

Phase one (engaging Phase) The lesson begins with an introduction to polymer 

The teacher uses plastic bags, polystyrene boxes and plastic food wares as example of polymers and explaining the monomers that form these polymers, the chemical process involved and the benefits and harmful effects of these polymers to human health and the environment. 

The teacher divides the students into two groups and distributes worksheets to assist them in analysing the life cycle of these polymers. The two groups discuss the benefits and harmful effect of the polymers to the current and future generation. 

The teacher asks questions to assess the students understanding of polymers and its properties. The teacher summarizes the lesson by reflecting on cognitive, economic, societal and environmental aspects of polymer production and asks students to review literature and prepare a folio on the environmental, economic and societal consequence of using polymer such as polystyrene.
