I was thinking about this today. There are so many things that happen in classrooms that I don't think happen in the natural world. For example: if I open a new box of tissues, suddenly 14 students need to blow their nose. Or what happens to pencils? I truly don't understand this one. I don't have a pencil sharpener in my room that works well, so I will take a huge handful of new pencils to another class, sharpen them and put them out for the kids. (They have their own supplies/desks, but without a place for them to sharpen pencils, that part doesn't work well for us). The next day they are all saying they need pencils again--they can never find their pencils! I don't know if there's like an elf that comes in and steals them or what. What other phenomena do you experience?
