Question

Y. E. S. ―a small group of high school students is not just learning about the envi?ronment around them,but they're actually doing something to improve it.

"This group has done a series of projects,from recy?cling about 600 pounds of tennis shoes,to over 50        cellpho?nes ,"said Patrick Merrick,a school teacher and Y. E. S. adviser.

The idea for environmental projects came about two years ago and it gradually became a part of an environmen?tal science class. In class,students would learn about a topic? design a project,carry it out and then take it to the community（社区) .

"Before every topic,we spent several weeks learning about the how,what and why of the idea," said Maddie Frank and Shawn Hanson,students in Y. E. S.

One of the goals,Frank and Hanson said,was to find out how much energy their school used throughout a school day.

"We decided to carry out a school energy audit (审计) ”，they said. " We divided up the classrooms among the students in our class. Each student recorded how much energy was being used in each classroom."

"We have been able to save money with the help of our school energy audit,make money with both the shoe and the cellphone recycling,keep a large amount of garbage out of the landfills (废物填埋地) with those recycling projects and make it possible for community members to use energysaving things”，Frank and Hanson said.

While the group is working towards making a differ?ence in the environment around them,they express their thankfulness for people's support.

"Without the help of our community and school,we would not have been able to make these recycling projects possible," Frank and Hanson said.
