This activity helps students learn basics about amino acids and proteins including: structure of amino acids; functional groups of amino acids; peptide bonding; primary, secondary, tertiary, and quaternary structures, and more. The guided inquiry model works by asking a series of simple questions and then later some questions inviting larger reflection on those answers with an eye toward synthesizing new information about larger ideas. It is meant to be done in groups of 2-3 over a period of about 30-45 minutes. It is best used to introduce the topic of amino acids and proteins, as it is a self-contained activity. No prior lecture should be given, but a student-share-out and review discussion would be idea.
