I am going to teach in a two year private college in September. Currently I am in the process of determining what laboratory experiments will the students do so that I can be prepared with the necessary laboratory equipments. My question is, how important is it to have a lab on measurement instruments such as Vernier calipers and micrometers? If I am to have a lab on this topic, is it better to use manual instruments/digital instruments? I was thinking that manual instruments might allow them to understand the concept of measurement uncertainities better. What are your thoughts? Thanks for your responses. Gamma.
