     Charter schools operate with public money but without many of the rules that govern

traditional public schools.In the United States the rules for charter schools differ from state

to state.But in general these schools have greater freedom to decide what to teach and how

to teach it.

     The "charter" is a performance contract.It establishes the goals of the school and other

details like how student performance will be measured.Fortyseven million students attend

traditional public schools.But more than a million students attend charter schools.

     And now a group of charter schools have formed the Green Charter Schools Network.

The idea is to have environmentally friendly school buildings but to also go further than that.

The schools teach students to become involved in community issues that affect them and

the environment.For example,young children grow crops in a school garden and learn

about healthy eating.Older students help recycle waste from the cafeteria.And local schools

share what they grow in community gardens with people in need.

     Jim McGrath is president of the Green Charter Schools Network.He says there are

about 200 "green" charter schools across the United States.He says the plan is to also

include traditional public schools as well as private schools.

     Jim McGrath:"The most important thing is that every one of us-every child,every

adult-has a responsibility that their action,every action we make has an effect on the earth

that we live in.And that our natural resources are not unlimited.And that if we want a

positive earth for future generations,we all need to make commitments to be agents of

change so that we don't destroy our natural resources."

     T he Green Charter Schools Network holds its first national conference this October

in Minnesota.It will include companies and organizations like Waste Management and the

United States Green Building Council.We sincerely hope that their goal is to expand the

movement across the country.
