Determining the Dimensions of a Molecule

SCIENTIFIC CONCEPTS/PROCESSES

• Use inductive approach to determine diameter of a molecule
• Calculate the thickness and area of a monolayer
• Appreciate the value of indirect method

Can you measure it? Of course you can, and this kit will show you one method to do that.

The diameter of a molecule is determined inductively because it can not be seen. Ordinary measuring instruments are obviously useless. This comprehensive series of activities introduces students to the value of the indirect method of measurement, its application and the arithmetic involved.
