These materials can be used to teach about Macromolecules (proteins, carbohydrates, lipids, and nucleic acids). These activities are appropriate for high school Biology students but can easily be adapted for health classes or middle school life science. Student Objectives: Describe the general structure, subunits, and examples for each of the four types of macromolecules. Understand the process of dehydration synthesis. Create models to show the arrangements of these polymers and macromolecules.
