OtherDescription:
In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another. First, learners compare the scents of orange peel and lemon peel, which both contain two versions of limonene (a stereoisomer). Then, learners compare the scents of crushed caraway seeds and crushed mint leaves, which each contain a version of carvone (another stereoisomer). Use this activity to help learners discover how a molecule's shape affects smell.
