# 18 Determination of the Set Time for Epoxy Adhesive
Students recognize epoxy glue formation as two part polymerization (usually the curing agents act as co-monomers). They monitor the reaction by the changes in viscosity of the reacting mass, the temperature rise and fall, and the...
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
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...
