This
radio
broadcast
discusses
the
history
of
magnetism
from
the
time
of
its
discovery
by
an
apocryphal
Greek
sheperd
until
the
late
16th
century
and
the
work
of
William
Gilbert.
There
is
also
discussion
of
who
pioneered
the
study
of
magnetism,
what
theories
they
constructed
from
its
curious
abilities,
and
how
the
power
of
the
magnet
was
brought
out
of
the
realm
of
magic
and
into
the
service
of
science.

This
eight-session
professional
development
course
for
in-service
and
pre-service
biology
teachers
is
based
on
the
PBS
documentary
Evolution.
It
is
designed
to
address
the
nature
of
science
and
how
Darwin's
development
of
the
theory
of
natural
selection
illustrates
the
process
of
science,
and
to
deepen
teachers'
understanding
of
the
theory,
evidence
and
processes
of
evolution.
Also,

This
lesson
includes
a
theory-evaluation
activity.
A
set
of
five
scenarios
(theories
for
how
diverse
life
came
into
existence
on
Earth)
is
divided
evenly
throughout
the
class,
so
each
student
is
asked
to
evaluate
one
theory.
Students
then
come
together
in
groups
of
five,
so
that
all
theories
are
represented
in
each
group,
where
they
are
compared
and
evaluated.
Each
group
reports
to
the
entire
class

This
lesson
provides
an
opportunity
for
students
to
extend
their
understanding
of
the
three
models
studied
in
previous
lessons
by
using
them
to
explain
phenomena
and
by
comparing
them
to
one
another.
Students
will
work
in
groups
to
use
the
models
of
Paley,
Lamarck,
and
Darwin
to
explain
the
origin
of
complex
structures
like
the
eye,
the
existence
of
fossils,
and
the
variety
of
pigeon
breeds.

This
article
examines
the
idea
that
managing
the
Earth's
complex
systems
and
their
dynamics
is
the
next
great
challenge
for
the
engineering
profession.
The
effects
that
human
engineering
has
on
the
environment,
whether
intentional
or
not,
must
be
taken
into
account
on
a
global
scale.
Earth

engineering
is
meant
to
do
so
by
augmenting
existing
engineering
disciplines
