Rhubarb - leaf or stem?

As part of our reading contract the story, 'That's the Idea' in Junior Journal 44, we looked all the school gardens and listed all the fruit and vegetables we could find.  We found a huge patch of rhubarb in the garden by Room 30, and had to decide whether to eat the stalks or the leaves. 

After some discussion, we decided to cook the stalks, as Ruby told us that the leaves were poisonous - we made the correct choice!  Some people enjoyed eating a cup of stewed rhubarb and appled instead of brain food after it had cooled.
