Our Worm Farm

We have our worm farm in the classroom again for 2012.  We enjoy feeding our worms our banana peels and apple skins from our lunches.  Because there was lots of white stuff growing in our worm farm, we emailed Mr H (our environmental expert) to find out what was wrong.  There was nothing wrong - this is all part of a normal healthy worm environment, but we did aerate and freshen up the soil just to make sure everything was right.  The photo shows the white "stuff" that we were concerned about.
