I just tried that, she said she's getting kids to clean them after.I just told the teacher who asked for pooters that CLEAPSS won't allow it. Same teacher asked for spirometer the previous week which I said no to. I'm not cleaning up anything that has been spat on by teachers or students.
That practical is in Edexcel A level. I hate it.A temporary biology teacher here did dissecting locusts last year. I know they are just bugs but why kill them just to cut up and throw in a bin? (I had no part in buying or killing them)
