Subject: terrarium

Hello,
 
I am a high school biology teacher in Toronto, Canada, and I am trying to
help a group of students with a science competition.  The goal is to create
a closed terrarium using a 1L pop bottle, that creates the most oxygen
possible.  We are allowed to include any plant species, and anything
necessary for the plant to survive.  We can use soil, insects worms...  I
was wondering if you have any ideas for us?
 
Thanks,
