i’ve told this story but when i was in year four the best teacher i’ve ever had got frustrated by the fact that we weren’t having science lessons— we were a tiny rural catholic primary school, and the woman who taught science came in from offsite up until i guess she couldn’t be bothered anymore. and so my teacher sought to compensate through what i imagine were varied means, but what i remember is the two consecutive days where he passed the butcher on the way into work and brought us a) a pig bone and then b) a cow heart, which he hacked open with one of the woodwork saws we never used and encouraged us all to touch marrow and flesh respectively
