What have we been doing in the laboratory for the past 40 years? Have our experiments changed for better or for worse? Has the laboratory experience benefited our students or just turned them off? This presentation will look at laboratory experiments in mainly commercial laboratory manuals, for both first-year majors and non-majors, over the past 40 years.
