Reflection: Developing a Conceptual Understanding Monomers make Polymers - Section 2: Introduce New Material

 

I like teaching this lesson because I feel that I have c"cracked the code" to increase students' understanding of how macromolecules are made.  As a teacher, we use whatever we can to aid student understanding and this lesson allows me to utilize videos, visual aids and atomic models to help increase my students understanding of a conceptual topic.

Use of the linking toys helps students see that monomers make up polymers.  As I discuss monomers and polymers, I walk around with the linking toys in my hand, breaking and making bonds as I instruct.  The video clip reinforces the concept and also serves to show the relationship in another way.  Lastly, allowing students to actually form a water molecule by removing a hydrogen ion and a hydroxide ion clarifies how dehydration occurs and bonds form.

This is one of my favorite lessons because students are able to gain a better sense of the dehydration synthesis and hydrolysis reactions.

Monomers make Polymers

Unit 5: Unit 2- Cells
Lesson 18 of 30

Objective: Students will understand the how the process of dehydration synthesis allows the carbon molecule to form macromolecules that perform vital functions in cells.

Big Idea: Monomers are like links in a chain.
