This lesson covers chiral molecules, which are important in carbohydrate and protein chemistry. Understanding the difference in their structures helps with understanding the different biochemical properties of molecules with similar structures. In this lesson, students will be introduced to chirality through a teacher-led multimedia presentation and demonstrations. In cooperative groups, students will then study the concepts in more depth, building molecular models and producing their own slide shows for the class. Different groups within each class will cover different aspects of chirality, with the whole class completing a presentation of the material in the unit.
