In this episode of PDTV, host Katie Blunt visits Grant Elementary in the Murray School District.

Last year the Siuslaw 97J School District changed our food service operation from a national supplier (Chartwell’s) to in-house food service. Our Food Service Manager instituted an organic philosophy and wanted to source local produce. Utilizing our school garden program we now help supply fresh produce for our Siuslaw Elementary School cafeteria. Crop production is stronger in the 4/5 wing because of wind protection from the building. Florence experiences high winds and we are located close to the beach so we have constant sand blowing into our crops. The K-3 garden beds do not have the same protection as the 4/5 beds, and as a result have a lower yield. Our goal is to have students design and engineer wind barriers for these beds and then present the best solutions to our school board so that we can get funding to implement our ideas. This project can be used in any school with a garden by using preexisting barriers on a the school property. The unique environment of the school would dictate the lessons required to be adapted to fit the environmental needs of the community. If the school is lacking a garden, the students can focus on an at home garden project.
