It's sometime in the not-so-distant
future. Scientific advances have
made it possible to genetically
engineer embryos in laboratories.
Any disease can be eradicated, as
can other “defects,”
such as a bad temper. As a result,
American society has stratified:
People whose genes have been tweaked
to perfection are groomed for great
things, like space exploration.
As for those with less auspicious
beginnings? Well, there’s
plenty of janitorial work to be
done here on Earth.
The likelihood of such a future—the
plot of the 1997 science fiction
film “Gattaca”—is
up for debate. But some scientists
and educators warn the chances of
science running amok are greater
if today’s schoolchildren
aren’t taught about the next
potential technological revolution—nanotechnology—and
its implications. Some analysts
predict that nanotechonology will
generate an industry worth 1 trillion
dollars in the next decade in the
United States alone. “The
pace of nanotechnology is breathtaking,”
says Akhlesh Lakhtakia, a professor
of engineering science and mechanics
at Pennsylvania State University.
As a result, Lakhtakia and others
are calling for nanoscience to be
integrated into high school, middle
school and even grade school curricula.
“I want our children and grandchildren
to be able to cope with this because
I don’t want them to become
slaves of oligarchy.”
Born in the 1980s with the development
of the scanning tunneling microscope
that enabled scientists to work
on a nanoscale—that is, one
billionth of a meter—nanotechnology
involves manipulating molecules
and atoms to build structures with
new properties. Since all materials
exist at this level, the technology
involves scientists of all stripes,
from engineers to chemists to medical
doctors. Among its much-touted,
potentially wide-ranging applications
is a cure for cancer, supercomputers
500-times more powerful than those
today and chips capable of storing
the entire content of the Library
of Congress. Consequently, “nanohype”
has given rise to a host of fanatics
and naysayers, from those who embrace
the technology as the key to transcending
the human condition to others who
believe that tinkering with nanoparticles
is sure to open Pandora’s
Box. “The truth usually lies
somewhere in the middle,”
explains Nigel Cameron, director
of the Center on Nanotechnology
and Society at the Illinois Institute
of Technology in Chicago. Nonetheless,
he says, “it increases to
a huge degree a far greater capacity
to manipulate the natural order.”
Not surprisingly, other countries,
such as China and Taiwan, are already
teaching children about nanotechnology
as part of their standard curriculums,
according to Judith Light Feather,
founder of the Texas-based Nanotechnology
Group (www.thenanotechnologygroup.com),
a foundation that promotes nanotechnology
education. “You go into a
grade school [in the United States]
and say nanoscience, and they look
at you like you’re from another
planet,” she says. Light Feather
works with universities to obtain
grants to develop programs for teaching
nanoscience in K-12.
In fact, 20 percent of National
Science Foundation funds granted
to universities for nanotechnology
research is earmarked for the development
of K-12 nanotechnology education.
As part of a 13-university network,
the Georgia Institute of Technology
teaches basic nanotechnology concepts
and applications to children by
holding workshops at its research
facilities. Elementary, middle and
high school students can tour the
university’s labs and “clean
room,” a dust-free environment
where nanotechnology research takes
place. Elementary school students
use s’mores for a larger-scale,
hands-on lessons in how these tiny
chips are made. Diana Palma, who
heads up Georgia Tech’s program,
says the kids are fascinated. “I
tried to find every conceivable
motivational hook in the classroom
as a science teacher for 20 years.
This is it.”
At
Lawrence University in Appleton,
Wis., Karen Nordell, an associate
professor of chemistry, facilitates
week-long workshops in the summer
for middle and high school teachers.
Rather than teaching a stand-alone
course in nanoscience, she looks
for ways to supplement and integrate
nanoscience into the teachers’
curricula by using it as an example
in the science courses they are
already teaching. She’s developed
a short experiment, for instance,
where kids actually synthesize gold
into nanoparticles. The result looks
something like grape juice, which
demonstrates how properties—like
color—change on a nanoscale.
“There’s usually a sort
of ‘gee whiz’ factor,”
Nordell says. “That’s
a very important part of keeping
students curious about science.”
Nordell uses the experiment as a
launching point to talk about gold
nanoparticles, which hold promise
as a cancer therapy, and other applications
of nanotechnology. “One of
my goals is to get them interested
in the problems that haven’t
been solved yet,” says Nordell.
She hopes nanoscience will attract
kids to science the way space did
for kids in the 1960s.

But nanotechnology education isn’t
just for budding scientists. Kevin
Ausman, director of Rice University’s
Center for Biological and Environmental
Nanotechnology, stresses that all
kids should learn about nanoscience.
“Nanotechnology is the next
plastics,” opines Ausman.
“It’s poised to explode
on the market.” Once that
happens, it will generate workforce
demands, from manufacturing lines
to sales forces, and all workers
will need to have an understanding
of nanotech concepts. Since 2001,
Rice has sponsored nanoscience training
for seventh-grade physical science
teachers in Houston, including weekly
workshops, summer internships and
sabbaticals. Another Rice program
currently being tested in six states,
Nanokids, uses actual anthropomorphic
molecules synthesized in the laboratory—they
look like stick figures—to
instruct kids in the concepts of
nanoscience through interactive
multimedia.
Proceed
Cautiously
Meanwhile, Cameron cautions that
there is a fine line between education
and promotion of technology. “What’s
the message here?” Cameron
asks. “If it’s that
[nanotechnology] is wonderful, then
that’s not education.”
He questions the motivation of those
who believe that children as young
as kindergarten need to be prepared
for nanaotechnology. The enormous
societal and ethical issues can’t
be ignored, argues Cameron; “Otherwise,
there’s a danger of the whole
thing collapsing into public relations.”
Penn State’s Lakhtakia agrees
that nanotechnology can’t
be taught in a vacuum. He’s
developed a plan to educate children
in grades six through 12 through
interdisciplinary team projects.
Just in Time education, as Lakhtakia
calls it, would present nanotechnology
in a context, warts and all. For
example, he envisions eighth or
ninth graders investigating water
filtration systems based on carbon
nanotubes. Initially, they may examine
the effectiveness of nanotubes compared
with charcoal water filters. Next,
they could determine the system’s
commercial viabilty. And what about
disposal of the filter cartridges?
Would there be health hazards? How
about neurological damage? Is it
conceivable that behavior patterns
would be altered? If so, how would
those who were affected impact society?
At the core of Just in Time education
is the synthesis of humanities and
the STEM disciplines. “People
who are primarily humanities-minded
should have to work with people
who are primarily science-minded,”
he insists. “Unless we do
that, the change in the political
landscape will be enormous.”
He points to the fall of the former
Soviet Union as an example. While
Soviet universities churned out
highly skilled scientists, they
were overspecialized. “They
couldn’t do anything else,”
Lakhtakia says. “I don’t
want to live in a world where either
scientists dominate or science is
exploited to dominate people.”
Ultimately, he says, it’s
up to regular citizens to prevent
such a scenario. “In a participatory
democracy and technological society,
it behooves everyday citizens to
know how money is made. You don’t
have to know quantum mechanics,
but you do need to know that light
travels in optical fibers and can
be used to communicate, for example.”
The public needs to be sophisticated
enough about nanotechnology to be
able to distinguish the applications
that are dangerous from those that
are not, adds Ausman; “Otherwise,
you could be throwing away the cancer
cure along with the hazards.”
