Traditionally, schools that emphasized the practice of a discipline granted Bachelor's of Arts degrees. Schools that emphasized the science of the discipline granted Bachelor's of Science degrees. (The same is true for Associate's and Master's degrees.)
However, over the many years, the lines have blurred -- and schools with "arts" vs "science" degrees often look pretty much the same. Sometimes there are some minor differences in the graduation requirements and/or administrative procedures -- particularly for schools that offer both options for the degree.
It's best to talk with the particular school to find out particulars.
