BOSTON -- A local elementary school is working to reduce the amount of trash it produces.

NewsCenter 5's David Brown reported that Lisa Grasso's third-grade class at North Walpole's Fisher Elementary School is part of a trash experiment.

For two weeks, they collected all of their juice boxes and snack wrappers. One day of trash weighed more than 3 pounds. Then they received a Green Pack from a nonprofit education foundation. The pack included a water bottle, thermos and reusable snack containers.

"It's just insane, the number of disposable bottles and disposable drinks from water -- everything -- that are filling our landfills. Just grab a reusable water bottle, rinse it out, throw it in the dishwasher and use that. It makes a big difference," said Victoria Waters, of the IXG Education Foundation.

As a mom and the founder of the foundation, Waters is making a difference by initiating change with the children.

"They can help keep our planet green, and that they do have the power, and it's really, really simple and easy little things," Waters said.

The simple idea of reusing has spread through the school. All 473 students made an effort to reuse and reduce.

"It's amazing. I'm amazed to have that little bag on the scale and not record an ounce. That's amazing, and they did it," Grasso said.

"I think it's really great because I want everybody to reduce that much trash so everybody can help the environment," student Devon McKinney said.
