I wanted an activity that students could do where they could make two monomers, bond them together to make a dimer, and then bond even more together to make a polymer. Since we had already made our paper atoms (Do-it-yourself paper molecular model set) and had some practice making molecules, I decided we could use them to understanding anabolism and catabolism in macromolecules. We just did this lab the past week and it took 2 days since I had to walk around and grade 9 groups for each category of macromolecules. It went well, except I had to skip making the polymers since there was a time constraint. They did really well making the enzymes and seemed to understand how the enzyme helped break apart bonds, but had some difficulty understanding where and when the bond formation occurred. I had to give them some help in imagining scenarios where bonds would be formed. All in all, it was a worthwhile activity and I think my students now understand macromolecules and their structure and function.
