School Stories
Edison Environmental Science Academy -
Kalamazoo, MI
Determined to incorporate
its greenhouse and gardens into the science curriculum, the Edison
Environmental Science Academy (previously Edison Elementary) has
made great strides in working with students and teachers to realize
the benefits of school greenhouse gardening. The school had been
plagued by low state test scores and high attrition before it
applied to become a Magnet School through the Federal Magnet Grant
Project. Edison received $1.5 million over three years. Additional
money has enabled the school to partner with the Kalamazoo Wildlife
Center and become a premier theme school for environmental education.
At Edison, the greenhouse and gardens are not worked into
the curriculum; they are the curriculum. Part of this is a direct
result of the work of environmental science technician Julia
Kirkwood. Her job is to develop the outdoor infrastructurein
other words, landscape the entire school property. With the
help of students, Julia has created a beech and maple tree forest,
started an oak and hickory tree forest, grown a swath of native
Michigan prairie, created a butterfly garden, bred insects,
propagated seeds and flowers, created specialty alphabet and
cereal bowl gardens, dug a pond, and designed the soil-based,
hydroponic, and aquaponic systems in the 24-foot by 48-foot
year-round greenhouse.
The Scientific Method as a Way of Life
This outdoor classroom is used by the entire school. First graders,
for example, learn the basics of soil-based greenhouse planting
by experimenting with how seeds grow in a variety of media.
They also learn how humans use plants such as corn, wheat, rye,
herbs, and cotton for food and clothing. "We strive for all
of our work to be inquiry based," says Julia. "We focus on the
scientific method for everything we do."
This is atypical for an elementary school. "We struggle with
a general lack of teacher knowledge," notes Julia, "yet all
of the teachers are excited about the environmental theme."
Julia has a degree in wildlife biology, and she partners with
a curriculum specialist to help the teachers grasp the environmental
basics and get a foothold on this radical transformation of
their school day.
Water Culture Inquiries
Exploring hydroponics begins in second grade, and becomes more
sophisticated in the upper grades. Fourth graders, for example,
study how environmental pollutants cause nutrient and light
deficiencies in plants. The students devise a system devoid
of phosphorus to see firsthand what a plant hungry for phosphorus
looks like. They then conduct research to determine what type
of pollutantacid rain being onecreates this result
in the natural world.
Hydroponics isn't just for a well-funded theme school. With some
basins, PVC pipe, adequate lighting, and a $10 pump, anyone, Julia
insists, can create a hydroponic system. "Hydroponics for Everyone"
is her battle cry and the title of the book Julia has used to jump-start
her own program.
On the heels of hydroponics is aquaponics, which teachers introduce
to the fifth graders. Through Julia's carefully built system of water
basins connected via planted channels to a 300-gallon fish tank, kids
learn how the environment naturally filters wastewater.
Taking the fifth grade work one step further, the sixth graders
study stream monitoring and how wetlands act as natural filtering
agents through the triad of plants, fish, and fish waste. Throughout
the unit, the kids test the water at four locations for nutrients
that can be pollutants in a natural waterway, such as phosphates
and nitrates. They also test for bacteria, ammonia, and pH levels.
The four staggered sites allow the kids to deduce how well plants
filter potential pollutants in a river system.
Ongoing Funding
The
most expensive aspect of supporting this type of work is paying
the heat and light bills for the greenhouse. To keep the infrastructure
humming, Julia recommends working the greenhouse projects into
the curriculum as seamlessly as possible. "If you show how benchmarks
are being met," says Julia, "the administration is more likely
to support the work and provide maintenance funding."
