Being a TA forms an integrated part of my life as a grad student and has been one among my best and most cherished memories at Macdonald Campus. Though some considered doing the same course repeatedly over semesters boring, every semester felt like a completely new and enriching experience for me for a number of reasons:
1. New minds to shape with group of students exhibiting different pre-cognitive perceptions
2. It is stimulating to observe how new students familiarize themselves with laboratory settings and enhance their skills as the labs grow progressively more challenging.
3. Most of the times, this experience is rewarding with students saying or giving Thank You cards at the end stating how happy they’ve been to experience the Biochemistry Labs.
Interestingly, this semester, a new lab was designed and incorporated in the biochemistry lab manual – DNA Extraction. Simple in the process, part of the lab involved crushing strawberries and using kitchen chemicals such as liquid soap, water and sea salt as extraction buffer to coax DNA from its confinements.
Though sceptical at first that DNA can be extracted from strawberries with simple kitchen chemicals, at the end of the lab, the students were beaming as the thin, thread-like DNA aggregated in the ethanol layer. Excited comments resounded in the usually quiet lab:
“Oh My God, there’s DNA…?”
“I guess it’s the soap which has maybe weakened the phospholipid bilayer of the cell membrane…what could be the role of salt?”
“I can’t believe this is DNA…”
“It’s so gel-like …”
For me, it has been equally exciting to observe students standing at the realms of their own “discovery” with eyes glittering in awe, and brains actively trying to locate the how and why of biochemical processes.
As far as I can remember, while I walked down the lab answering questions, instructing good laboratory techniques and verifying results, boring has never been my sentiments. Though it is with great sadness I’m saying adieu to my cherished biochemistry labs and warm animal science department, these labs will always hold a special place in my heart as because of my TA experiences, I discovered my passion to shape young minds in science and I am looking forward to carry research in making science education more accessible for all students…
I hope being a TA has transformed your life too.
