Step 1. Find a topic you are interested in doing research in (ie polymers, analytical, organic, etc) and then go to the library and find some academic papers (JACS, etc) that you might have an interest in.
Step 2. Note the school of the primary author and then look up the chemistry department on their website. Find out if multiple professors are doing similar work at that university.
Step 3. Contact the University about going to graduate school or alternatively, the actual professor. Most students gain access to graduate school through the generic department route, however, about 20 % or so contact a professor personally and then the professor "recruits" the student into the program.
Notes: You might be excluded from the most elitist schools (ie MIT, etc) since they want GPA's close to 4, however, you should be able to get in to the majority that you apply to. You will also want to research the location of the school (ie crime rate, cost of living, weather) etc. In 1995 (when I started grad school), the stipend was between $14,000 - $20,000 US / year. I don't know the stipend rate now, but it is probably slightly higher. Thus, a "scholarship" isn't needed (although if obtainable it does make for a better standard of living for the 4-5 years you are in school).
