Perry’s
Green Dream
In late April of 2009, the Perry Elementary
School 5th & 6th grade class started working on a
creative project. The students were given the following question: “ How can we help our school, community and environment?”
Students brainstormed with many different ideas ranging from a basketball
recycling game, wind turbine and a greenhouse. Students voted for the
construction of a school greenhouse. Students wanted to grow their own fresh
organic produce to be used in the school’s cafeteria.
The
main obstacle in the green house project was funding the project. School
budgets are very limited in the funding of extra resources and projects. The
students were given the task of finding grants to help with the purchase and
construction of a school greenhouse. The students found some grants that
promoted both school activities but also community projects. The students all worked together to right the
grant proposals. Another obstacle was how to maintain the greenhouse in the
summer. Perry has an excellent 4-H program (The Quoddy
Kids). We contacted, 4-H leader and school board
member, Denise Harris. Mrs. Harris and her 4-H crew do many projects in which
they study plants. The greenhouse will help reinforce many of their growing
lessons. Mrs. Harris also volunteered to help us with the project proposal. We
were successful in our applications to three separate grant-funding entities,
The Maine Community Foundation, Maine Agriculture in the Classroom and The
Perloff Family Foundation.
The
funding from the Maine Community Foundation came from the Washington County
Fund. This is a grant used for community projects. This fund also supported the
building of the outdoor basketball courts at the school (2007). The fees from
the Agriculture license plates support the Maine Agriculture in the Classroom
fund. It supports programs that build upon agriculture being taught in the
school using hands-on products. The Perloff Family Fund supports innovative
projects in the local schools. The Perloff Family has supported Perry
Elementary School projects for many years. They have funded the LEGO Robotics
program and all of the online video projects at the school.
Our
original proposal involved the purchase of a greenhouse kit from a hardware
store. The kit we were going to use was a durable structure, but it would only
allow us a limited growing season. Denise brought a new type of greenhouse to
our attention, a year round greenhouse. This is a greenhouse modeled after a
greenhouse at Brooksville Elementary School built by The Greenhouse Project, a
program started by Tom Adamo and Tony Ferrera. The year round greenhouse would allow us the
opportunity to grow fresh vegetables throughout the school year. The greenhouse
will be an energy efficient 16’ X 16’ stick built
greenhouse that costs roughly $50 a year to heat (based on Brooksville
numbers). The framing for the greenhouse consists of a 6 X 6 X 16 base, 2 X 6
knee walls, and 2 X 4 rafters. The north wall consists of T111. The roof of the
north wall is finished with 30-year architectural shingles. The east, west, and
south walls are tied together with polycarbonate sheets. There are two steel
exterior doors (east and west) and heat activated vents. The growing beds are
be heated by using the hot air at the peak of the greenhouse. The heating
system involves using perforated pipe and crushed stone at the base of the
beds. Along the north wall and the peak, we have 6-inch dryer vent pipe that is
fed into a galvanized “ T”. Where the perforated pipe and 6-inch pipe
come together we have an inline fan controlled by a thermostat. When the
temperature in the greenhouse goes below the set temperature, the fan will be
activated. The fan will pull the hot air from the gable peak and distribute the
air throughout the pipes. The hot air from the pipes will heat the rocks, thus
heating the beds. We have also added another heating dimension to our project.
We put PEX tubing and crushed stone in one of the beds. We are looking at
installing a solar panel that will heat the liquid
(propylene glycol) and then circulate that hot liquid through the PEX tubing.
The Solar and PEX method will have the same radiant heating of the stones as
the hot air system, but it will give us another variable to study. We will be
able to see which system is more effective and efficient.
The
Perry Elementary School Greenhouse Project has been a true community effort.
Students worked with Dean Preston, a civil engineer, on the site selection
process. Students surveyed three sites on the school grounds. The students
ranked each of the sites based on ground level and composition, water
availability, microclimate, solar exposure, and aesthetics. During this
process, Mr. Preston showed the students how to use the various tools of his
trade and the importance of each of the elements.
Once
the site was selected, the groundwork needed to be completed. Dean Preston,
Shawn Harris, Denise Harris, Lee Harris, and the Perry Town crew (Stanley
Morrill and Tate Stevens) did the groundwork. The groundwork crew along with
Richard Clark, of Clark’s Plumbing and Heating, laid the piping for the
heating system and set up the knee walls (built by Shawn Harris). Tommy Pottle, of Pembroke Lumber Company, cut the lumber used for
the greenhouse construction. Paul Mitchell, of Mitchell’s Electric, is going to
lay the conduit, wire and hooked up the electricity. The construction of the
greenhouse was completed by parent and community volunteers: Shawn Harris, Denise
Harris, Lee Harris, Dean Preston, Cody Preston, Richard Clark, Stephanie
Allard, Brian Duffy, and John Turner. The polycarbonate panels were ordered
through the Washington County Food and Fuel Alliance, under the direction of
Washington County Manager, Betsy Fitzgerald. Dr. Reeser Manley, of Shead High
School, has been consulted on soil mixtures. Coast of Maine donated the compost
mix. Richard East, of The Growing Concern, is going to work with the students
on planting the crops. Tom Adamo and Tony Ferrera provided guidance and support throughout the
project.
Perry’s Green Dream is a program that can
teach lessons across the curriculum, throughout all grade levels, and
throughout the community. This is a project that teaches or reinforces concepts
for all learning styles, Visual Learners, Auditory Learners, and Kinesthetic
Learners. Students use practical hands-on applications of classroom
instruction. To ensure project sustainability, students are going to sell the
surplus produce and compost soil at the Mustang Market, a student run
farmer's market. Students will use the funds, from the market, for the purchase
of additional materials and greenhouse maintenance. Perry Elementary School
students and the Quoddy Kids will be responsible for
the planting, maintaining, and harvesting of the crops. This is a true school
and community endeavor. Our Green Dream is also going to be used as a model for
our community. We hope to demonstrate to the community how to grow fresh
produce year round at a very low cost.
