When I started the nature unit one year, students told me they were sick of hearing about reducing, reusing, and recycling from a bunch of teachers and administrators who drove SUVs and didn't have recycling bins in classrooms. The next year, I was able to run one of my classes without printing any paper and I was driving a Mercedes fueled by used vegetable oil.
Don't be afraid to ask your students for advice. They HAVE been talked at their entire lives about Earth Day being every day and all that, but it's up to you (and them) to do more than just talk about it.
When your class comes up with ideas using this download, so something as a class. Then write to someone to let others know what you're doing.
I remember having these inservices where some consultant would come in and tell us that their consulting firm would be saving us a million dollars over the next decade because they recommended shutting off the lights. Our district could have saved the million and the $100,000 consulting fee by using the form you can download here and using the intelligent people on staff (called teachers) as the consulting firm. Go ahead and try it, intelligent administrators. You have talented, intelligent people working for you already. Stop hiring big corporations to fix the problems your own staff can handle. Buy resources on this site and trust your fellow educators.
