When I was an undergrad, I tended to choose Liberal Arts electives that have something to do with my field. So those electives were classes in Philosophy of Science, History of Science, and even a rather unique, interdisplinary course that studied how science and technology are depicted in classic literature such as "War of the World", "Slaughterhouse 5", "All Quiet on the Western Front", "Brave New World", etc. The latter was because we were required to have at least 3 credits in literature since the physics dept. was part of the College of Letters and Science.
While many people think that these classes are a waste of time, I actually found them fascinating. I didn't want to major in them, but I did find them interesting enough to do quite well in all of them. They become useful later on in my professional career because I can see the perspective of science (and physics in particular) from people who do not major or work in it, especially on how they would misinterpret many aspects of science if all they got were something out of philosophical, historical, literature work. You have to know what and how people understand things before you can start explaining to them what you know.
Since such classes will probably be your first observation of how other people who aren't science majors think and understand about science, these classes become a useful practice ground for what you had to deal with later.
