Students ranked certain techniques and other aspects of the lab by order of difficulty, with selection of the number 1 being too difficult and number 5 very easy; students ranked interestingnesswith number 5 being very interesting and number 1 not interesting. The percentage of students (n = 50) answering in each category is shown. In most aspects, the majority of the students perceived difficulty to be on the easy side of neutral (between 2 and 3), and in most aspects the students thought the project interesting to very interesting (between 4 and 5).
