We have started a new unit in Science:  organisms .  The kids were able to make a terrarium last week.  So far they have planted a tree seedling and moss.  We are learning that while all plants need water, you can lovingly give them way too much.  We are waiting on the arrival of our millipedes and bess beetles.  I have heard the millipede are escape artists, so I'm hoping I don't find one in my purse one afternoon!
