Outdoor Learning Environment

“How do they get the tomato on the vine(藤、蔓)？”

The question shocked Hillis. It reminded him of the time five years ago when he was volunteering at Beattie Elementary School in his daughter’s kindergarten classroom. He’d been reading the children a book about gardening.

“These kids had only seen vegetables in supermarkets,” he says. “I felt that something important was missing in their lives.”

So he went to work. Hillis and his wife, Sally, made the local government believe that it was necessary to create an outdoor learning environment. He and other volunteers raised more than 30,000 dollars to make such a project. The project was designed like the Platte River. Like the river, the school’s front walkway turns east to west, so they planted things along the walkway, such as native grasses which can be found along the river too.

Today, students are greeted every day by the cedar-mulched creation(雪松覆盖的表面), which spreads the length of three city blocks. In the back, there’s a garden, with twenty 1 ton rocks lying in the ground, where teachers hold classes.

The outdoor effort has changed things inside, too. For science, children plant seeds and, based upon each seed’s size and weight, guess how large a vegetable will grow to become. For arts and crafts, they collect fallen leaves and make designs out of them. Other science lessons make up a large part of the outdoor learning process. “No matter what time of the year it is,” Hillis says, “there’s always something going on.”
