Hydrofracking Topic of Earth Day Talk

Hydrofracking and its impact on the local area will be the focus of an Earth Day talk Friday, April 19, at Keuka College.

Helen and David Slottje

David F. Slottje and Helen H. Slottje, co-founders of Community Environmental Defense Council Inc. (CEDC), an environmental law firm, will speak on “Fighting Fracking: A View from the Trenches.” at 3:30 p.m. in Jephson Science Center  104. It is free and open to the public.

According to Kasey Klingensmith, professor of biology, law firms across the state say local governments can’t stop fracking in New York because state law takes away local authority to enact laws relating to the regulation of the gas industry.

“But Helen and David argued that banning drilling was not the same as regulating it,” said Klingensmith. “They developed and advanced the thesis that New York municipalities may utilize local land use authority. This allows them to enact laws prohibiting gas drilling and associated activities outright. It also provides protective laws—which are not laws relating to the regulation of the gas industry.”

For more than three years, the Slottjes have crisscrossed the state, teaching towns that they can enact laws to keep drilling out, and drafting those laws at no charge.

“Following CEDC’s lead, nearly 150 municipalities have passed either a ban or moratorium on gas drilling,” said Klingensmith. “CEDC’s work has energized the anti-fracking movement, brought hope to local residents, empowered local governments, and continues to send Albany politicians a clear message that New York will not be fracked.”

Helen Slottje received a bachelor’s degree in economics with honors from the College of the Holy Cross and received her law degree from the University of Pennsylvania. studied at Harvard Law School from 1990 to 1991.

David Slottje graduated magna cum laude from Syracuse University, where he was a member of Phi Beta Kappa. He received his law degree from Emory University.

A Bird in the Hand …

Like most expectant parents or relatives, the wait for “D-day,” the day of delivery, is a torturous enterprise. But once the little one is safely arrived and nestled down for naps and feedings, the crowing begins.

So it is for the students in Keuka’s ornithology class and Assistant Professor of Biology and Environmental Science, Bill Brown, who have been keeping close watch on several nestboxes Brown placed along the outer perimeter of the campus, near the treeline beyond Davis Hall and the Red Barn Theatre. The nestboxes, which look like simple birdhouses to the untrained eye, are large enough for birds that prefer to live in cavities such as tree trunks to build a nest inside.

The nestbox of the Black-capped chickadees.

It has been a long wait, marred when eight of nine “active” nests of Eastern bluebirds and Black-capped chickadees were destroyed by house wrens and house sparrows, whose habit is to kick out any eggs already laid in a nest in order to take it over and lay eggs of their own. But one chickadee nest escaped the ravages of the migratory menaces, and that nestbox is the ultimate destination for Brown’s class on this, the final day of the outdoor lab for ENV/BIO 331.

Before paying a visit to the home of the new nestlings, the scientific term for baby birds recently hatched, the class stops at one additional box, where a house wren has begun to lay new eggs – three so far – after returning to the area in the last week or so.

Carefully unscrewing one side of the box, Brown reveals the wren’s nest, made primarily of twigs, with soft grasses, bluejay feathers and hair lining the inside. Fishing around with his hand, he pulls out three tiny pink-toned eggs.

Eyes (and Ears) Wide Open

Bundled warm in hoodies against the morning chill at Keuka Lake State Park, the students are standing still, listening intently. From the branches of trees nearby come chirps, calls and sing-song melodies, rising over the sound of the waves lapping the shore.

“What do you hear?” asks Bill Brown, assistant professor of biology and environmental science, who holds a Ph.D. and specializes in ornithology, the study of birds. Binoculars hang suspended from the students’ necks, but Brown wants them to listen first.

Seniors Steve Stout and Justin Henry record bird species they've identified during an outdoor field lab.

Pencils poised over palm-size waterproof notepads, the handful of students lower their heads and jot down four-letter codes for different species as they respond with the names: Mourning dove. American robin. Cardinal. Canada goose. Carolina wren. Downy woodpecker. [Eastern] Pheobe. House finch.

This is ENV/BIO 331, Keuka’s ornithology class, where one of Brown’s primary objectives is teaching students to master identification of some 104 different species of birds by sight. Thirty-nine of those species must also be identified by sound. And those are just the birds found here in New York state.

According to Brown, almost 90 percent of “birding” is done by ear; the rest comes from knowing what to expect in a given setting, whether that may be a small cluster of trees near a building, along a road, or deep in a forest fragment. (more…)

Scientists in the Making

Chemist Dmitri Mendeleev is credited with developing the first periodic table of the elements, the most important reference in chemistry because it arranges all the elements in an easy-to-read chart.

This table was key for the nearly two dozen St. Michael’s School (Penn Yan) and Penn Yan Elementary School students who visited the Keuka College campus Nov. 19 for the Chemistry Club’s Kids’ Day, held in Jephson Science Center.

Chemistry Club member Richelle Coons adds food coloring to 'elephant toothpaste' as St. Michael's School fourth-grader Sarah Loucks looks on.

The elementary school students used the table to find the atomic numbers of such ingredients as potassium and iodine before creating “elephant” toothpaste, a foam that looks like “human” toothpaste.

Conducted once a semester, Kids’ Day shows elementary school students “how much fun science is,” said Club Secretary Janelle Davidson. “We want to get the kids interested in science at a young age and [Kids’ Day] gives them the opportunity to conduct experiments in a fun and safe way.”

Davidson, a senior biology major from Cortland, showed the youngsters how to use cabbage juice as a pH indicator.

“Acids and bases will make the cabbage juice turn different colors, depending on the pH in the acid or base,” she said.

Chemistry Club president Katie Barnhart, a senior biochemistry major from Warsaw, showed the youngsters what happens to marshmallows, a glove filled with air, and a hard-boiled egg inside a vacuum. The children also dipped cotton swabs in different salts and club member Jason Troutman, a senior biology major from Kirkville, placed the end in a Bunsen burner and, depending on the salt, a different color flame was produced.

Several elementary schoolers poke the 'ooblek' to feel its properties.

Club members also showed their young friends how to make ‘ooblek,’ a type of slime that has properties of both liquids and solids; conducted experiments by combining sugar and fire; and created fireworks with gummy bears.

The highlight of the event was watching Assistant Professor of Chemistry Andy Robak, Chemistry Club adviser, create bubbles by placing a gas-filled hose under water and dish soap. He got his hands and arms wet under the gas bubbles, scooped up the bubbles, and Barnhart set the bubbles on fire.

Other members of the Chemistry Club who took part included: Kyle Morgan, a sophomore biochemistry major from Alfred Station; Steve Stout (treasurer), a senior environmental science major from Locke; Brian DelPineo, a sophomore biochemistry major from Oneida; Ashley Hager, a sophomore biochemistry major from Chemung; Sonya Decker, a freshman occupational science major from Chemung; Kathlyn Parrish, a freshman biochemistry major from Cincinnatus; Caitlin Adams, a sophomore biology major from Redwood; Andrea Burgess, a senior management major from Hemlock; Alex Jones, a senior biology major from Conklin; Chelsea George, a freshman biomedical major from Strykersville; Krystal Russell, a freshman medical technician major from Berkshire; and Richelle Coons, a freshman adolescent biology major from Lyons.

A Veterinarian in the Making

Editor’s Note: This is the 2nd in a series of stories saluting members of the Class of 2011. We asked division chairs for story ideas and they in turn contacted faculty members for ideas. We believe they came up with some terrific profiles.

Emily Credit

Andrew Robak, assistant professor of chemistry, liked Emily Credit from the first class in which she took with him “because she did as much teaching as I did, and helped solve problems in the chemistry lab.

“Since then, I have gotten to know her better, and I only became more impressed,” said Robak.

Credit, a biology major from Canandaigua, chose Keuka because she liked the small class sizes, and the individual instruction she would receive from her professors.
