Addition Polymerization: Preparation of Polystyrene Using Two Types of Initiators
Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...
Cornell University
Polymerization
Explore condensation polymerization and additive polymerization through hands-on activities. Young scholars first model additive polymerization with paperclips. They finish the activity by using condensation polymerization to create a...
Curated OER
Polymerization Experiments
Students study the concepts of polymerization and the function of crosslinkage. In this polymer lesson students complete a lab activity and write down their observations.
Curated OER
Polymers
Present polymers to your chemistry class with this practical PowerPoint. Begin with a definition and the properties of polymer materials. Branch out into diagrams of polymer structure. Consider the two general types: addition polymers...
Curated OER
Polymerization Experiments
Students explain the process of polymerization. For this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

A Half DNA Ladder Is a Template for Copying the Whole
The experiment known as one of the most beautiful experiments in biology changed the way we think about DNA. Learn about the experiment and the scientists who designed it—as well as the scientists who built on the results—with an online...
Curated OER
Polymers
Students make polymers in the lab. In this polymers lesson plan, students make a nylon fiber polymer chain. They define monomers, polymers, addition polymerization, condensation polymerization, crosslinking and cyrstallinity.
Curated OER
Organic Chemistry Reactions
In this organic chemistry reactions learning exercise, students are given a table with 8 different types of reactions that occur with organic molecules. Students answer 3 questions about the reactions given in the table and indicate...
Curated OER
It's the Slime Time
Students experiment to understand the basic concept of polymerization and to understand the dissolution theory. Student experiment with polymers to understand its behavior and the mechanical behavior of polymer networks.
Curated OER
To Smell or Not to Smell, That is the Ester
Students explain the basic concepts of polymerization. Students participate in a lab to create a crude preparation of carboxyl esterase and test its effectiveness in reducing the residual monomer in an emulsion such as paint.
Curated OER
Super Glue Fuming of Latent Fingerprints
Pupils explore latent fingerprinting. They observe a supervised demonstration of the process that real-life crime scene investigators sometimes use to identify latent fingerprints. In addition, they brainstorm ways to improve the process...
Curated OER
Intrinsic Viscosity
Learners treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.
