Science Class Homework I used to have a friend when I was a kid in primary school. One day, we both failed to do a science class homework which could be anything on a stiff paper using sticks, glue, paint, etc, and representing something from Nature. So he took a plant in a small vase from the school garden, put it on cardboard from a box we found on the trash, wrote something on it (I don't remember what it was) and left it there on the teacher's desk, without her noticing. And we received a very good grade for the job.
