I completed a pseudo-internship-like experience offered by one of my undergraduate professors this semester. The job title was "biology technician," but my jobs were more geared towards learning than actual work.
Tasks I learned were: cleaning glassware in the biology department, organizing microscopes slides, cleaning microscopes, calibrating digital pipettes, and basic autoclave operations.
There were many other tasks, but I fail to remember them now, but would these skills be a boon to a grad school application, and if so, how would I incorporate them into a 1 page resume? I even filmed a video on autoclave use for instructional purpose.
