When I was TAing gen chem we had a cute lil red 40 UV-VIS spectrometry lab. I got done explaining absorbance and a student raises her hand and asks, "But then what is reflection?" Like lay off kid I'm just an undergrad.
Another time when I was TAing quant one of my students was confused by the hydronium-hydroxide thing and asked if there were any other structures for water. I told him that there were loads and that it was a question for the professor who confronted me a couple days later telling me not to confuse his students lol
The approximations, assumptions, and historic artifacts we use to make science digestible to students can be frustrating, but also kinda fun. It makes it feel all secret and wizardry.
