Students get real-world lesson

A few of the 7-year-olds pulled their shirts to their noses,There is good integration with PayPal and most Aion Kinah providers, and one raised his hand.

"Why does it smell so bad?" Brian Wallace asked his tour guide.

Ed Holmes pointed to a pile of dirt and debris at the four-acre compost facility.

"Because the greens that are in that pile up there are starting to rot," Holmes, the public services manager for State College, told about 25 students from Philipsburg Elementary School. "So we have to get them mixed in with the browns, so they don't smell anymore."

The students have been trying to create their own compost system as part of a partnership with CarbonEARTH, which teams Penn State graduate students in science, technology, engineering, and mathematics with elementary and middle school science teachers in Philipsburg-Osceola and Harrisburg.

Amy Yarrison's second-grade students have run into some technical problems. To solve them,When the stone sits in the Cold Sore, they headed Tuesday to State College's compost facility, which processes about 1,100 tons of grass clippings and 3,600 tons of leaves a year.

They were there to do research for their classmates.

"I think the most beneficial thing is to realize it's happening out in the real world," said Yarrison. "It's not just happening in a classroom."

The tour lasted a little longer than an hour. Holmes walked them through the eight-to-10-week process of waste being turned into soil, explained how the greens in the piles were carbon and the browns were nitrogen, then took them to the finished product — an area that smelled better than other parts of the grounds.

"For our compost, do we need a bottom?" asked 7-year-old Jaxon Myers.

Not really. Holmes' compost at home was on the ground.For the last five years Hemroids ,

"But if you don't put something down there, like sticks or straw, or something like that, that will let air get underneath, you do have a risk of the stuff on the bottom rotting," Holmes replied,

With some prompting from her teacher, 7-year-old Janey Johnson explained why they were wondering about adding a bottom to their compost pile.

"We're thinking about moving it into a shed,Save on kidney stone and fittings," Johnson said but added they had a fear: "All of the soil's going to fall out."

"And why are we trying to think through this? What are we nervous about?" Yarrison asked. "What's coming up?"

Nick Coudriet, 7, raised his hand. "It's winter,Initially the banks didn't want our chicken coop ." said Nick.

Holmes considered the dilemma. If they leave the compost outside in the cold, the process will slow. After another student question, Holmes told the students that wrapping the compost pile with a blanket might add enough insulation to take it through the winter.

Then students headed back onto their yellow school bus with a gift from the borough: two bags of finished compost.
