Experiment Opportunity

I am on my daughter's Montessori school's Green Committee.  They are asking parents and friends to donate "green" items to sell at the "green table" on Tuesdays this spring.  If anyone would like to make and donate (I'll help offset the cost if you will make it!) cleaning products or something else not too expensive that is "green," we can have it count towards your experiment.

To my understanding, the Green Committee is working to earn enough money to build a "green space" for students to play and learn in.  This space is going to be where there is presently an unused swimming pool (The Montessori moved into the old Jewish Center building and grounds).  They are wanting to fill in the pool and have gardening space, etc.
