Condensation Polymerization
Learning Goals
I can use the term polymerization correctly
I can explain the process of condensation polymerization reactions
I can explain the difference between addition polymerization and condensation polymerization reactions
LESSON OVERVIEW (SPECIFIC EXPECTATIONS: B2.1, B2.4, B3.4)
Lesson Hook:
Show the following video on making nylon as an example of a condensation polymerization reaction. Before showing the video instruct students to listen out for the reactants used in this demo. Debrief with the class and let students know that today we will be learning about the discovery of the nylon fiber and how it was formed from a condensation polymerization reaction. This experiment can also be performed in class as a demo and have students fill out a POE chart: predict, observe, and explain what happened.

Teaching Strategy:
Video Tutorials: Below are links to two tutorial videos on condensation polymers. The first video is an introduction to what condensation polymers are in contrast to addition polymers (lesson from day before). The second tutorial provides a great explanation on the condensation polymerization process. Both tutorial videos are very engaging and highly visual with coloured text and graphics. This combined with the audio of the tutorial will be of great benefit to the audio/visual learners in the classroom.

Consolidation:
Create a Tweet!
Have students work in pairs or trios to create a 140 character summary of what they learned in today's lesson. If students have cell phones they can send out the tweet on a class #hashtag and the teacher can display the tweets on the projector as students send them in. If cell phone technology is not permitted in classrooms, this exercise is still beneficial as students learn to summarize key ideas in a limited number of characters and still get the meaning across. It is also a great way to get students to work in collaboration with their peers which provides an opportunity for assessment as learning. |
