Biology lessons

As you know Ali is a secondary science teacher and an hour ago there was this huge laugh from the office where she was marking year 7 books. She was marking a section on the human waste system.. this is what one pupil wrote.

"We need fibre in our diet because it helps us go to the loo by helping to push the toilet though"

Seriously, have you ever tried to push a toilet though .. i wonder if that is anything like child birth!

As if that wasn't enough, those last 3 words were in fact her second attempt writen in Biro on top of some white out! who knows what was there before!
