Lesson Summary

This lesson covers the topics of intermolecular forces and covalent bonding through the crosslinking of polymers. Students explore a real-world material science application for their knowledge of chemical bonds, elements, and polymer structures—a new type of bioink that is used to 3D print biological implants and scaffolds for growing organs.

Upon completion of this lesson, students will be able to:

  • identify covalent bonds and intermolecular forces in molecular structures and discuss differences in bond properties (i.e., strength, flexibility, etc.). 
  • relate molecular structure to material properties and polymer applications.
