Professor C.N.R. Rao is the author of Understanding Chemistry. He has contributed the ideas, concepts, and selection of activities that are presented in this CD-ROM. This multimedia package introduces chemistry to students between high school and junior college levels.
This was the first CD-ROM developed and produced by the multimedia group. The main objectives of the CD-ROM are to introduce chemistry in a stimulating and exciting manner, to arouse the curioisty of the user and to generate maore than a passing interest in chemistry.
The modules in the CD-ROM contain all the topics generally covered in school syllabus but are presented in a simple interactive manner. It has six lessons, which are complete in themselves. The topics in the CD-ROM have colourful visuals, animations, movie files to facilitate understanding of difficult concepts. Each module in the package can be viewed in any order. Hotspots are provided which give additional information about a person, concept or procedure. At the end of the each module there is a quiz section which the user can attempt to test his/her understanding of the module.
The other features of this CD-ROM are notepad, search, help etc.
They can be viewed in any order although a sequence has been recommended by us. The following are the six lessons:

1. Chemistry in a capsule
2. Elements and the periodic table
3. Chemical bonds
4. Structures and shapes of molecules
5. Chemical Energy
6. Chemical reactions.

The topics covered under each lesson are as follows:
