Geez, I guess it depends on where you live/work... I always had to have daily lesson plans, and a sub notebook with schedules, info. on the kids, etc. Even in EI with the toddler classes. I do remember teaching in public school many years ago on occasion covering someone's class and they may have just done homework. Or maybe I'm thinking of study hall duty... lunchroom duty was much more exciting! (yeah, right)
Hall duty, now that was really entertaining. Why are you at this end of the building? (because the hall pass says something clear at the other end...) Um, I had to get this thing out of my friend's locker and um, their locker is by the gym and then, um, had to get my whatever and my locker's over here, and then um... (Giving them the teacher look) never mind just go, get to class... while I'd keep one eye on them the rest of the way down the hall... Could jr. high kids ever come up with great reasons to be anyplace but where they were! lol
Boy does Jon need a break.
In 10th grade biology class, we had to do experiments with fruit flies to study genetics. We had to keep careful watch after the mating pairs were introduced to see when the first eggs were laid (based on the timing of the eggs, you could determine the fathers whereas later eggs could have been mixed...or something like that.)
My friend and I had to go check our flies in the bio lab during a lunch period one day. The hall monitor stopped us to ask where we were going, and we deadpanned in response, "To check if our flies are still virgins." We got past.
True story: one day, I actually caught two of the flies in the act. I am now able to cross "Witness sex between fruit flies" off my bucket list
And yes, after months and months of experiments in both 10th grade bio and 12th grade AP bio, I still remember the Latin name: Drosophila melanogaster.
