Rasayanashastrada Arivu is the Kannada version of `Understanding Chemistry' with the script in Kannada along with the voice over in Kannada.It has graphics/visuals, movie files of live experiments done to enhance understanding of the subject.

Rasayanashastrada Arivu can be used both as basic learning material and as a resource material by high school students and teachers.
The main objectives of bringing out the kannada version Rasanashastrada Arivu is to introduce chemistry in a stimulating and exciting manner, to arouse the curiosity of the user and to generate more than a passing interest in chemistry in students and teachers in kannada medium schools and to tap the talent in these schools. We believe that this interactive CD-Rom authored by Professor C.N.R. Rao, an internationally acclaimed scientist and educationist, will go a long way in providing quality software for
our kannada medium schools and further the cause of bridging the digital divide-a cherished goal of the Government of Karnataka.
