A prospectus will show what it is you'll be researching, the facets of how you'll conduct the research and the good that you believe your research will bring about. Be sure to check the guidelines for the institution you'll be writing the prospectus for. They may have specific formats which must be followed for your prospectus to even be considered. It's always a good idea to have someone else
. give it a once-over for you. But be sure it's someone that is willing to give you honest critique; you want to get this funding! For a sample of how to write your prospectus, visit this website: http://www.clas.ufl.edu/users/shegeman/prospectusguide.htm.
