Teaching Students About Polymerization

Polymerization is a crucial and fascinating topic in science, which involves the process of synthesizing large molecules by joining smaller ones called monomers. Students should be taught about polymerization as it is a fundamental concept in organic chemistry and materials science. Polymerization has many real-life applications, such as in the production of plastics, fibers, coatings, and adhesives. As a teacher, you can help students understand the basics of polymerization by using a variety of instructional strategies, such as visual aids, experiments, and hands-on activities.

Visual aids

Visual aids are an excellent way to introduce polymerization to the students. You can use diagrams and illustrations to show the molecular structure of monomers and polymers. Explain how monomers join together to form long chains of polymers with repeating units. You can also use animations or videos to demonstrate the process of polymerization. This will help the students visualize how monomers interact to form larger and more complex molecules.


Performing experiments is an effective way to explain the process of polymerization. You can conduct a simple demonstration using glue as a monomer and boric acid as a catalyst. Squirt glue into a bowl and add a few drops of boric acid, then mix the solution slowly. The glue will polymerize and form a rubbery substance that can be stretched and molded. This will help the students understand how catalysts interact with monomers to form polymers.

Hands-on activities

Hands-on activities such as making slime or play dough are an excellent way to engage students and show them how polymerization works. In this activity, students can make slime using PVA glue as the monomer, borax as the catalyst, and water as a solvent. When mixed, the glue and borax form polymer chains, creating slime. This activity will help students understand how different compounds interact to form new substances.


Teaching students about polymerization is essential as it is a process that is widely used in industry and technology. Students should understand the concept of polymerization to appreciate the many applications it has in the modern world. Using visual aids, experiments, and hands-on activities is an effective way to help students gain a better understanding of this vital scientific process. By making the process of polymerization relatable and engaging, students are more likely to retain the information and apply it in real-life situations.
